Okay so, good morning everyone, thank you so much for being here and for this opportunity, my name is Lluis Casabona and today I will talk about organic Field Effect transistors for near infrared light detection so first of all what is Neo infrared like and why is it important Neo infrared or n light is a type of radiation that we can find next to the visible spectrum devices made with these materials usually exhibit excellent performances however for some specific applications they might present some limitations for instance in flexible applications and for spectral selective detection um to address these issues uh we can build organic photo detectors these devices are made with Organic semiconductors which are highly conjugated organic molecules or polymers based on carbon and hydrogen these materials offer some uh advantages for instance they are compatible with flexible substrates and um of with large area fabrication uh we can um we have different types of photo detectors photo conductors photo diodes and phototransistors one type of electronic device that we can use to build organic phototransistors are the so-called organic Field Effect transistors or oets ofets are three terminal devices where the current flow from two electrodes that we call source and the drain s and D can be modulated by the application of a voltage in the third electrode called the gate these devices can be easily integrated in electronic circuits and are relatively easy to fabricate one of the main challenges of n organic photod detectors is to find photoactive materials that are able to absorb near infrared photon in this work we focused our efforts in this molecule here that you can see here which is Y6 Y6 is an end type semiconductor that presents an absortion spectr like this one with a peak in the near infrared at 841 nanometers and therefore shows potential as a possible candidate for n photo detectors and this leads us to the main objective of this work we just to study the potential of oets made with this material Y6 as prospective candidates for organic photod detectors and to optimize the fabrication conditions of these devices so the methodology that we followed in this work is as follows first we fabricated our devices then we characterized the organic uh semiconductor thin layer by different techniques in particular we focused on the crystallinity of this layer uh next we electrically characterized this electrical devices the O fets by different electrical measurements and finally the best of fets were studied as organic phototransistors under n Illumination in the following slides we will see each one of these steps in more detail so how we fabricated our devices first we started with a silicon wafer as our starting substrate where highly doed silicon acted both as the gate electrode and the substrate and a thin silicon dioxide layer as the dialectric material then we evaporated the source and drain electrodes by means of photolithography uh here you can see the the shape of the electrodes that we used which are inter digitated electrodes after that we coated um the organic semiconductor layer with a technique that is called blade coating for this we previously prepared a solution of our Semiconductor in chloroform and then uh we applied this blade coating technique which consists on preparing a meniscus in the gap between a blade and the substrate and moving the blade forward th creating this homogeneous thin film this technique is compatible with roll to roll and large area fabrication and finally um we did a thermal analing of our devices which consists on heating them at different temperatures in our case between 110° and 250° this step is extremely important as it allows us to obtain crystallinity of this particular organic semiconductor which enhances or typically enhances the performance device the device performances all of these steps took place inside of a glow box to avoid the gradation of our semiconductor here are the results of the thin film characterization um with the polarized Optical microscopy images we could see that samples are kned between 170 degrees and and 230° uh showed crystalline domains this could also be observed um with the X-ray defraction uh measurements as we observe some Peaks for these temperatures however for the highest temperatures we also observed some partial de wetting uh which is undesirable and therefore 170 and 190° were considered the optimal ones to achieve crystallinity of our semiconductor with these um devices and also the ones at 150 we perform some electrical measurements in particular the transfer measurement which consists on measuring the source and drain current as we sweep the source gate potential and by fitting this experimental data to this uh theoretical equation here we can extract the two figures of Merit of of fets which are the Field Effect Mobility which quantizes the ease with which charge carriers move along a semiconductor and the thresold voltage which is the minimum voltage that we need to apply to induce a pressable current in our device our results show that for crystalline samples the ones at 170 and 190 the mobility values and therefore the performance of our device were significantly higher than for the amoros sample which is what we expected uh moreover in particular the the highest value was around 0.1 for the samples at 170 uh regarding the thresold voltage we could see that uh we achieved values positive values for the crystalline samples which is what we expect for an end type organic semiconductor the best device es an at 170 were later characterized under illumination as organic phototransistors uh to do so we send some light pulses to these devices and here you can see an example of a dynamic measurement where you can clearly see how the current increases significantly when there is light insiding on the device um yeah El light from the amplitude of these steps we can extract the photor responsi photoresponsivity which is a key parameter to quantify the performance of a photo transistor um by performing several measurements like this one under SE under different conditions we could obtain these results which show that for different polarizations of our transistors the same tendency between responsivity of the device and incident Optical power or intensity of the incident light uh is as follows uh which follows this equation that you can see on top of the slide where this relationship is not lineal but um uh we have this relation where beta is always lower than one this shows that at lower incident Optical Powers we get higher response of our device and this leads us to the main conclusions of our work which is that we could successfully fabricate y60 feds um we also saw that uh a polymorph Y6 can be achieved aning at 170 and 190 degrees and that this Crystal in structures also provided the best performance of our device and finally we saw that um at lower incident Optical Powers we achieved higher response which uh aligns with the objective to be able to detect lower low quantities of incident light all in all Y6 is a potential candidate for our Ric photo transistors and uh further optimizations both in Silicon and in flexible substrates should be carried out and in the future hopefully apply these devices in real applications such as poo Symmetry and well thank you I would like to thank simat for this opportunity and to all my mmap fellows with whom I enjoyed a lot carrying out this project and that's all thank you so much for your attention if you have any questions please feel free to ask I will be delighted to try to answer them I have question to the first to the slide six yes okay it seems that the better personality is obtain for7 um yeah for the it is true that for the 170° um only one Peak is observed and with very low intensity the pigs could be observed um but the scale was uh very yeah the pigs were not as as significant as the ones at 190 because it's almost yeah um actually here maybe the image is not super clear and compared with the 190 um it is true that here you can clearly see the crystalling domains and here it's almost in the middle between a morphos and crystalline actually um so you could observe some crystalling domains when we when we did the electrical characterization of our samples we expected the 190° samples to perform to have a better better performance than the on at 170 and what we think it happens is that at 190 there might be some micr structural defects that we cannot observe uh with polarized microscopy images and this um decreases the performance of our device and maybe we should use other characterization techniques to further uh Analyze This okay thanks you welcome thank you 00:12:27.880 --> 00:12:30.880 thank you for see okay uh maybe English so uh thank you for presentation very interesting so I think the final um object is just human sensor no so this is a polymeric device and how it's have you consider studing how it affect by humidity or it is affected or something like that like the performance or yes um I don't know if it will show here um because I have I have extra light but they are hidden yeah um maybe I can I can look it up yeah so we did uh different stability tests of our devices because the organic semiconductors that we're using are known for not being the most St stable materials in air um the first stability test that we did was a bias stress where we measured um several times the transfer measurements the that measurements that I showed uh before and this was done 20 times and we can see a small shift here in the threshold voltage which is the minimum potential needed to switch on the device um and this these results were taken into account when when later doing the measurements under illumination and then I tried to test my devices in air because everything that I I did in this work was in a glow so in in and conditions so what I did was to take one of my devices 5 minutes out of the glowbox and then me um measure it again in the same uh equipment and you can see that the performance clearly uh diminishes so I yeah um in order to work with these devices in open air we should first um um code um yeah code them with other materials that are transparent in the near infrared um for them to work yeah thank you for the question good morning to everyone 301 00:14:50,440 --> 00:14:55,360 I'm going to start the presentation of my master thesis called processing of M tractus stainless Steels using fuse filament fabrication Advanced processing Technologies such as P injection molding and additive manufacturing are revolutionizing the way we design and manufactur components they are allowing us to combine different materials into a single piece taking advantage of the individual characteristics to obtain uh improved functionalities this opens up possib uh possibilities for a precise distribution of mechanical thermal electrical or chemical properties that with lead to the design of new applications achieving a high mechanical strength and tactility in the Steels is a longstanding challenge uh to get a a good balance between these two properties the current trend is to to apply thermomechanical treatments to the Steels to in order to get a uniform distribution of multiple phes in the micr structure uh however these multiac Steels as you can see uh have a limit a in the properties they can achieve so then several studies are showing that by alternating hard faces with soft faces in a mesoscopic scaling patterns is possible to achieve an exceptional combination of properties that is not possible by any other STS family these are called the mesas Steels and examples are the old damasus and the more recent multier Stills unfortunately uh conventional methods for producing multier steel Composites such as R bonded and Forge welding have some difficulties in obtaining complex geometries from uh raw material seats and also it had been seen that uh severe deformation operations favor the appearance of voids in the interfaces then additive manufacturing using multiple materials is a known technique but applying the multilayer still comet uh to this process is a newer and a greater area of interest uh currently mes structures uh have already been achieved by 3D printing by the direct type Technologies these are based on melting and this makes difficult to have a good control over the micr structure also it's possible to lose some alloying elements because of sulation and moreover cracks can form due to residual stresses from solidification so in this study we propose an Innovative approach by using fuse filament fabrication uh that is an indirect uh technology the process begin with by blending the metallic pwder with a binder that is then pelletized anded into a filament for printing after printing the binder has to be removed and we do this by a first solvent based debinding process followed by a thermal debinding and a cing stage uh the this is an indirect uh technology and that means that once you get the geometry you have to perform and to optimize more steps until you you get the final component uh this technology offers several advantages such as the good material combination flexibility and the most important one a good micr structure control however there are some uh challenges to to overcome in my in my work during the the master tesis I have focused on three main challenges the first one is related to the design of the fix stocks and the solution processes in order to obtain a windable printable filaments uh that is a very crucial process because all the the rest of the faces depends on the filament quality the second one is uh is to overcome overcome all the challenges using uh a two extruder printing process uh which involves the control of many parameters and requires a vast experience finally the highest complexity rely on the cing process when a rink cage uh takes place and compositional gradients are formed uh first we in this in this presentation I I will discuss combining uh two different stainless Steels uh tintic 316 L and A martic 174 pH searching for Unique com for a unique combination of mechanical and corrosion properties the challenges begin with the selection of raw materials both both patters have to s a similar compatibility with the binder so in this case we have selected uh PS with similar particle size particle size distribution similar uh morphology then uh the The Binding temperatures uh have to be similar in both materials so we have decided to use the same binder systems and finally we have maximized the solid loading uh to a 60% in both fix stocks in order to to reduce the contraction during cering and make the process more controllable uh about printing with two extruders many considerations have to be taken in in account the first is the filament retraction that is is necessary while printing to avoid ooing but can be problematic causing damages in the filaments we have solved it by reducing the filament retraction distance and by developing uh filaments with enough enough stiffness also a crucial factor is the axis nuel cero calibration and even a slight deviation can cause catastrophic results during centering finally uh printing is a process subject to variations and this can lead to microscopic defects as you can see we have partially solve it by implementing a printing parameter called overlap that consist in setting a percentage of overlap between materials about Shing we have performed a cing study between 3 1360 and 14400 Dees looking for the most suitable temperatures in terms of those factors for for both materials finally uh temperatures between uh 1360 and sorry 1380 and 1390 degrees uh were considered valid and as you can see we have uh notice the contraction differences between both materials while cering however this didn't suppose a problem while obtaining final measure structures like the one in the slide finally uh uh cine is a diffusive uh process and this results in compositional gradients so to control this effect that is very important to obtain tailor properties we have performed chemical composition analysis and micro harnesses profiles in this diagram we we can see how the interfaces and the martic bands increase uh with the growing cing temperature also it is remarkable the good uh bonding mat materials that have been achieved as conclusions uh uh the three main challenges have been uh overcome first we have uh a 316l and a 174 pH windable and printable filaments valid to material printing have been developed uh the the challenges of printing with chers have be overcome obtaining free defects uh geometries and finally um final M structures have been achieved with a a good bonding between materials and a good M structor control so we have demonstrated that the fabrication of M structors with the fuse filament fabrication technique is possible and promising finally uh we have also found some difficulties while obtaining other geometries because of the stresses during cering so we are uh planning to work on on performing the latry test and uh analyzing the most suitable topologies to to improve to solve these issues and to uh obtain the the best mechanical and corrosion properties.

 So this work has the ground SE the ground for obtaining future complex geometries with a combination of other materials, obtain unprecedented tailor properties on groundbreaking application.

 Thank you Bueno, Juan, muy bien, muchísimas gracias.

 Muy fenomenal la presentación que has hecho.

 Vamos a empezar al contrario.

 Si hay alguien de aquí, de los colegas, que quiera decir alguna cosa, que quiera hacer alguna pregunta, que se sienta libre de hacerla. Y bueno, y si no, pues vamos aquí a ver si la paz, presidente de socio, tiene algo que preguntar.

 Existe una?

 Si puedes ir a la diapositiva tres en un instante.

 Una vez.

 Donde esta?

 Parece haber un error.

 Ya se ha entendido.

 Perfecto.

 Pues es la siguiente.

 Donde tenías los resultados de micro dureza.

 Ah, vale. Es que me he perdido por.

 Por esto.

 La pregunta es.

 Por qué has usado micro dureza que tiene muy poca resolución espacial y no nano indentación, que para este caso hubiera tenido mucha más resolución.

 Y justo en la intercala, que es donde te interesa medir o hubieras podido tener una información mucho más clara.

 Y al final es que con toda la herramienta.

 De la que disponíamos, posiblemente hemos hecho tomas imágenes que yo digo en nuestro equipo de ventas y luego finalmente hicimos el análisis químico.

 Tomamos un método algo más preciso en el zoom, quizás para ver precisamente.

 Hacerte cerca del micrófono, porque si no, no se te oye.

 En las.

 Cosas que están fuera. No, de. Verdad, no se oye que hemos utilizado al final los métodos que tenemos un poco en la escuela y en el grupo y, ya sabes, lo hemos hecho lo mejor que hemos hecho.

 Una sugerencia del extranjero, porque posiblemente os de una información más precisa y complementaria a la que ya tenéis por imagen y por composición, que si mucho.

 A mi me pareció muy interesante el trabajo y has mencionado en varias ocasiones el tema de la resistencia a la corrosión, porque claro, aquí tú ves que tienes unos materiales que tienen tantas caras y de distintas composiciones, que luego cuando eso está operando en un sistema, habéis hecho alguna las medidas y no hemos.

 Llegado al final el TCM ha dado para los malo para lo que se ha contado.

 Evidentemente seguimos, tenemos que seguir más claro.

 Pues a ver si para la tesis puede dar muy buenos resultados.

 Enhorabuena, Juan.

 Vale, muchas gracias.

 Esfuerzos, full ingresos.

 hello everyone first of all I would like to thank the soci committee for selecting me as a fin finalist I'm very honored for that recognition as the chairman said I'm meono and today I'm talking about the master thesis I did last year at the University autonom Madrid under the supervision of Dr sharo and Dr miraya please don't be afraid of such a lar title what I'm explaining you today is how by a Noel stragedy we have already modeled and we are currently trying to reproduce experimentally we can dramatic dramatically um increase the performance of solar while reducing their cost I would like to start with a brief discussion of the energy situation in our worldall we are all familiarized with the need in our society to find a clean and renovable renovable source of energy here you have some a representation of the total war reserves of some non- renov renovable source of energy that as you know they are not only limit but also producing pollution problems and climate change nevertheless as per say earlier in only one year the solar energy that reach our planet is much higher than all that reserves together further more as you see here the cost of this non-renewable source of energy have been maintained over the years if not increased and on contrary solar photovolatic has gone from being the most expensive to the cheapest one in little more than a decade so what is our excuse here I mean we have the most powerful ER clean and cheap H source of energy at our disposal what is it what that we are not using it I personally don't know the answer to that question but as scientist the only thing we can do for the moment is continue improving even further this technology which is the main objective of the master thesis to do that we propose two different Pathways first of all the use of more accessible and cheaper materials and secondly increase efficiency of the devices regarding the first one we have to acknowledge the importance that silicon has in our society it has been the material used per excellence in almost every electronic technology as you see here the efficiency of these H silicon solar cells are ER for a long time now are optimal are near to the theoretical limit but the processing of this material requires thousand of degrees it is energetically expensive moreover it is controlled by Asian Powers so people rely on other countries to obtain it in this context Alli perides are very promising they have an octal structure where the vertices are Alli onion we have lead at the middle and we have an organic molecule or theion between octav the synthesis of this material is much easier and only requires 100° furthermore depending on their composition we can obtain different oo electronic properties as you see here band gaps over a wide range can be obtained so the Great properties of these materials have lead to an increase in the an increase in the evolution of the deficiency of pery solar incredible and a little more than a decade they are also at the level there are all there are and already at the level of silicon so okay now let's see the second approach to see how uh to increase the efficiency of the device I will start with the basic with the fundamentals of solar cell here you have a general schematic of a solar cell where we have a semiconductor as the absorbing layer and then we have a few other layers that ensure the operation of the cell let's illuminate it from above look at that Photon that is coming back coming down to be absorbed at the semiconductor suppose that that Photon has an energy quite higher than that of the bangard an electron from the conduction from the balance band will be well the animations are okay an electron is going to be promoted from the balance band to the condution band with that excess of energy but due to the low the low the less energetic State inside the vs this charge will thermalize eventually to the band EDS losing that excess of energy at the moment of the charge struction so as you see these thermalization losses are reducing dramatically the possible the potential efficiency of a solar cell leaving a the IAL limit at only 33% one could say that in order to mitigate these thermalization losses we should increase the band gap of the semiconductor to extract the the charge the charges at higher potential but if we do that if we increase the the energy of the bandup less photons from the incoming solar Spectrum will be absorbed so we will generate less current and this is H where the standing config configuration comes into play here we have two sub cells one on top of the other made of different materials that will absorb different spectral regions we first we first have a white B bang semiconductor that will absorb the most energetic photons leading to thermalization to higher potentials and then we will have the narrow bandas semiconductor that will absorb the remaining less energetic photons in this H configuration we have to think into account that the both two cells one on top of the other are connected in serious so the total voltage of the cell will be the sum of both voltages while the current will be limited by that subcell that produce l photocurrent so we will need to find what is known as current matching conditions it is that is to make both sub cells to absorb the same amount of like in order to maximize the total current cell if we fulfill that an a new theoretical limit open open UPS to 44% so as I told you before one of the most attractive properties of allight perides is the the Bon ability depending on their composition so we have all this composition suitable for a White Band Gap layer in a tund and luckily a few years ago some members of my group and others demonstrated that by a partial substituting of lead by team narrow bang AOS skite will also possible opening the possibility of all peros Sky tund solar cells okay H the problem this material have the steam light lead perite is that they do not absorb as efficiently as the previous composition so it's going to be the limiting factor in a tund device the problem the the solution we propose to WorkOne this problem is the use of metallic nanop particles that support localized surface plasmonic resonances as the one you are seeing in the simulation with these particles we can surgically increase the electric field at the exact position and at the exact spectral region we want so by means of introducing this nanop particles inside the narrow banga perite we can increase its absortion so basically we are like doctors operating a solar cell to increase its absorption so we did the simulations using the fdtd method at first not in a tment but in a single Junction model as the one you are seeing here and we optimize several parameters the particle material between copper gold and silver the radius of the Spheres and the volume concentration that we introduce those SPS inside the peros skite and we obtain these results for the uh the current calculated for different sizes and concentration obtaining this optimal case for this silver Nano particles let's analyze it in more detail here you have the absor and spectrum of that optimal case represented in Orange in compared to that of a reference cell without using nanop particles and as you can see there's a a considerable Improvement specifically at long wavelength now what you are seeing is the differential absortion per per unit of volume at different at crossing your planes at different wave of interest at your right we have the reference cell where we can see this fabrio type interference typically in a Plano paral multier structure and at the plasmonic cell we can see this multi multi multipolar plasmonic resonance coming from the nanop particle so from these figures we can deduce that the absortion enhancement comes from a fine coupling between both effects which is what we have been optimizing during the the simulation and finally we went for a Tandon device we did the same optimizations in a model as the one you are seeing but this time using as a starting point the optimal nanop particles previously calculated for the single Junction solar cell and we obtaining the result for the match current finding this optimal case as I told you before due to the series connection of both two cells in a tandem we we have had to calculate the current matching conditions in every Point here and as an example of that is what you are seeing here as we increase the front peros Sky thickness more photons will be absorbed there so the current in the front suell will be increased as you see represented in green on contrary less photons will reach the r Sur cell so the current there will be decreased and that's going to be a point at which both currents will match with each other maximizing the total current of the cell and that happens at 1536 for a red fa and Cel represented in Orange and at 1637 for a for the optimal plasmonic tanden cell represented in blue and this current enhancement corresponds to more than a super and absolute efficiency enhancement so I have I I hope that I have convinced you that um using designing solar cells using more affordable material is the path for the future and for that reason we have modelized all per Sky T solar set using nanop particles to overcome their limitations we found a system that promise an absolute 2% efficiency enhancment and to finish just say that the experimental demonstration of these uh models is already in progress I'm in contact with yunhan at the University of of Cambridge who is already making this device this old peros skan and solar cell the s of the of the nanop particles have already begun and first attempt to include this in the solar cells have also been made and thank you all of you for your your attention and thank to all my group for their support thank you very much Bueno, pues nada Jaime, que la verdad es que es una faena, que los tres sois tan buenos.

 Es muy bueno para la ciencia, pero muy malo para esos demás que solo tiene un premio.

 Aunque yo creo que habría que hablar con el presidente para que el año que viene haya más premios, porque es que de verdad es una pasada.

 Los tres que habéis presentado y no sé si alguien en la sala quiere.

 Por favor, profesor.

 Yo hice tu.

 Sí, yo.

 Yo tengo una pregunta de ese hombre sobre el material.

 A mi me encantan las rosquillas de plomo, pero como todo, como nos llevamos con la normativa europea de no usar plomo, porque en otro tipo de.

 Dispositivos en los que yo uso proscritas, estamos obligados a suprimir el plomo en todas ellas.

 Efectivamente, el plomo, la toxicidad del programa es un claro problema actualmente.

 Pero fíjate que esta aproximación que nosotros estamos tomando va en la línea de reducir.

 Aparte de que los grosores ya de por sí son bastante límite, son muy finos estas capas, entonces el contenido de plomo es bastante escaso y todo este dispositivo llevaría un encapsulado para tratar de que no haya fugas.

 Pero aparte de eso, toda esta aproximación se trata de aumentar la absorción del material para reducir la incluso más, incluso las.

 Pero ten en cuenta que las velocidades de las que estamos hablando son estas que sustituimos el plomo por el estaño.

 En el caso la tandem es verdad que la de arriba seguiría teniendo plomo, pero y la línea del trabajo es intentar un poco reducir ese contenido en plomo en sentidos, tanto en la composición de la pelotita como en el grosor de la velocidad.

 Pero sí es verdad que el plomo es una de las cosas que más echan atrás actualmente a las florecitas.

 Bueno, gracias Paloma, que desahogo.

 No, la verdad es que lo suscribo y muy bien para la ciencia y futuro de la ciencia, pero muy mal de nuestro tiempo por dentro, en un pais en un aprieto.

 Pero bueno, muchas ni eso.

 Solamente añadir que es la diversidad de campos en los cuales se trabaja, lo cual es muy de agradecer.

 Quiere decir que nuestra ciencia es muy ancha y eso es muy bueno.

 Muchas gracias.

 Bueno, pues muchas gracias.

 Ahora la profesora Paloma Fernández y el profesor José Ignacio Pastor van a hacer entrega, que yo llamaría a los tres finalistas para que vengan aquí.

 Muchas gracias, Sandra.

 Buenas.

 Bueno, eso ocurrió.

 No todos son prosélitos.

 Si, bueno, improviso.

 Pues no se improvisa.

 No? Para mí es una placer estar aquí.

 Bueno, además, como todo en este año, está siendo un poco la primera vez después de la pandemia.

 Por fin.

 Entonces, la verdad es que es un placer, porque me he vuelto a encontrar con gente con la que quiero mucho.

 Creo que con la lleva un montón de tiempo sin podernos encontrar a todos.

 Es un placer. Es un placer además, ver como las cosas que nació hace unos cuantos años, pues con esfuerzo pero casi como venga José Ignacio, tu pones unas fotos allí en la escuela y simultáneamente yo pongo otras fotos aquí en el pasillo de mi facultad y hacemos un concurso en Twitter y hacemos algo para dar, para celebrar, para apuntarnos.

 Bien y tu y no.

 Te vayas en 30.

 Minutos, vamos ya muy viejos.

 Pues es un placer ver como aquello que bueno es que fue literalmente dos exposiciones simultáneas, una en la facultad de pases de la Facultad de Física de la Complutense y otra en el pasillo de esta facultad, y que de ahí ya hemos llevado hasta aquí.

 Entonces eso me parece que es bueno.

 Una cosa por la que nos tenemos que felicitar todos y que desde luego, pues me hace sentirme muy feliz.

 Y la única faena pues que eso es demasiado bueno.

 Y entonces pues como soy demasiado bueno nos lo ponen muy difícil a la hora de decidir estas cosas, porque habría que daros un premio a todos.

 Saben que está muy bien, porque bueno, cuando algunos ya llevábamos un poquito retirada, pues vemos que las nuevas generaciones verdaderamente prometen y eso está muy bien y en parte.

 No nada más felicitaros a los tres.

 Ahora, si el ganador tiene la responsabilidad de ganar el concurso europeo, o sea que tiene una responsabilidad enorme detrás de él porque va a representar a toda su madre en una competición europea al Mundial realmente del más alto nivel.

 Enhorabuena de nuevo a vosotros y a vuestros directores de los trabajos.

 Esos serán el lunes normal que nos veremos de nuevo.

 Bueno, pues empezamos por los finalistas.

 Los finalistas son aves blancas y todo esto.

 Juan Jiménez a Lumbreras y Jaime Bueno, Benito y bueno, ya tiene menos emoción.

 Claro, el ganador en ese caso, bueno, tendrá mi enhorabuena.
