    The Spanish lose interest in heating
    Most Spanish feel disaffected by the problems of climate change. And much more after the outbreak of the economic crisis, which has preoccupations the environmental concerns of citizens over the past two years, the study society due to climate change of the Foundation Mapfre. In particular, the warming has gone from being the fifth overall problem of the Spanish in 2008 to eighth in 2010 and has completely disappeared from the list of risks to Spain. The report presented yesterday by Secretary of State for Climate Change, Teresa Ribera, is a problem that the Spanish away in time and space, as they believe that only affect future generations and poor countries (55% ).

    Alice was beginning (pasado simple) to get (infinitivo) very tired of sitting by her sister on the bank, and of having nothing(pasado progresivo) to do: once or twice she had peeped into the book her sister was reading (pasado progresivo), but it had no pictures or conversations in it, 'and what is the use of a book,(Presente simple) thought Alice 'without pictures or conversation?' So she was considering (pasado progresivo) in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her. There was nothing (pasado simple) so very remarkable in that; nor did Alice think it so very much out of the way to hear the Rabbit say to itself, 'Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered (pasado perfecto) at this, but at the time it all seemed quite natural); but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, (pasado simple) for it flashed across her mind that she had never (pasado simple)before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge. In another moment down went Alice after it, never once considering how in the world she was to get out again. The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping herself before she found herself falling down a very deep well. VERBOS: Was, beginning, having, reading, is, considering, use, made, feel, looked PREFIJOS: Re-markable SUFIJOS: Beginning, having, reading, considering, looked, making, wondered, picking, suddenly, occurred, stopping, falling.

    In particular, the warming has gone from being the fifth overall problem of the Spanish in 2008 to eighth in 2010 and has completely disappeared from the list of risks to Spain. The report presented yesterday by Secretary of State for Climate Change, Teresa Ribera, is a problem that the Spanish away in time and space, as they believe that only affect future generations and poor countries (55% ).

    El nuevo catalizador permitirá la comercialización de células de combustible revolucionarias

    El diario de la ciencia (el 15 de junio de 2010) barato, mucho mas liviano que antes y permite el funcionamiento continuo.
    --Que baterías tradicionales no pueden ofrecer--- las células de combustible de acido formicas directas pueden revolucionar el mercado de la electrónica portátil. Un nuevo catalizador desarrollo en el instituto de química física de la academia Polaca de ciencias habilitara un uso extendido de células de combustible, investigadores dicen.
    Uno apenas puede encontrar a un usuario consumidor de electrónica que no este irritado por los problemas con el suministro de energía. Las baterías se gastan rápidamente y requieren los reemplazos continuos o toma un tiempo largo de carga. Las células de combustible podrían mejorar significativamente el confort de usar los dispositivos electrónicos. Su comercialización, sin embargo se impide por muchos problemas tecnológicos. Un nuevo catalizador desarrollado en el instituto de Varsovia representa un hito sustancial en la manera a la diseminación de barato, durable, ligero y ambiente amistosa células de combustible operadas por el acido fórmico.
    La célula de combustible es un dispositivo que convierte la energía química en energía eléctrica. La corriente se genera directamente debido a la combustión de combustible en la presencia de catalizadores usadas en el ánodo y el catado de la célula del combustible. “la eficacia teórica de conversión de energía química en el poder eléctrico puede alcanzar el cien porciento incluso. Las mejores células de combustible actuales, impulsadas por el hidrogeno, alcanzan gasta un 60% en la visa real en comparación, la eficacia de motores de baja-condensación están baja en 20%”, dice el doctor Andrzej Borodziniski de IPC PAS.
    El obstáculo mas grande a la diseminación de combustible de hidrogeno es el almacenamiento del hidrogeno. El problema resulto ser sumamente desafiante tecnológicamente y todavía esta esperando por soluciones satisfactorias. Una alternativa para alimentar células impulsadas por el puro hidrogeno es la tecnología celular del combustible de metanol. El metanol, sin embargo, es toxico y la célula de combustible impulsada por el metanol deben producirse con los caros catalizadores de platino es mas, la célula de combustible de metanol tienen el baja potencia y se operan a una temperatura relativamente altas y tan potencialmente peligrosas (aproximadamente 90º C).

    Una solución alternativa es la célula de combustible de acido fórmico. En este caso, la reacciones ocurren a la temperatura ambiente, y la eficacia y poder de esta célula de combustible son claramente mas altas que aquellas de metanol. Además, el acido fórmico es fácil de guardar y transportar. Tener, sin embargo, el combustible celular del acido fórmico estable en el funcionamiento una necesita un catalizador eficaz y durable.
    Una ventaja del catalizador desarrollado IPC PAS, particularmente importante del punto de vista económico, es que conserva sus propiedades mientras operado en la ley de pureza del acido fórmico. Tal acido fórmico pueden producirse fácilmente en cantidades grandes, también de la biomasa, para que el combustible para la nueva célula de combustible fueran muy barato

    Jose Gonzalez, Yaxibel Salazar y Keren Betancourt. Nuevo catalizador que permite la comercialización de pilas de combustible revolucionario La ciencia todos los días (junio15, 2011).nuevos catalizadores económicos mucho más ligero que antes y que permite la operación continua lo que las baterías tradicionales no pueden realzar, tiene directa células de combustible de ácido fórmico puede revolucionar el mercado de dispositivos electrónicos portátiles. Un nuevo catalizador desarrollado en el instituto de química física de la academia polaca de ciencias permitirá un uso generalizado de la pila de combustible, según los investigadores Difícilmente se puede encontrar un usuario consumidor electrónicos que no se irritan por problemas con la fuente de alimentación, las pilas se agoten rápidamente y requieren reemplazos continuos o tomar un largo tiempo de carga. Las celdas de células de combustible mejoran notablemente la comodidad de uso de dispositivos electrónicos. Su comercialización, sin embargo se ve dificultada por muchos problemas tecnológicos. Un nuevo catalizador desarrollado en el instituto de química física de la academia polaca de ciencias en Varsovia representa un mito sustancial en el camino a la difusión de la barata, durable células de combustible ligero y fácil para el ambiente impulsado por el ácido fórmico. Pila de combustible es un aparato que convierte la energía química en energía eléctrica. La corriente se genera directamente, debido a la quema de combustible en presencia de catalizadores que se utilizan en el ánodo y el cátodo de la eficiente combustible celdas teóricas de conversión de energía química en energía eléctrica en las células pueden alcanzar hasta el cien por ciento. Las mejores células presentes combustibles, propulsadas por hidrógeno, llegar hasta el 60% en la vida real. Para la comparación, la eficiencia de los motores de baja compresión es tan baja como 20%, dice el dr. andrzej borodzinski PAS de la CIP. El obstáculo a la difusión de los combustibles es el almacenamiento de hidrógeno. El problema resultó ser muy complejo técnicamente y aún está a la espera de soluciones satisfactorias. Una alternativa a las células de combustible alimentada por hidrógeno puro es el combustible de metanol la tecnología celular, sin embargo, es tóxico, y las células de combustible de metanol alimentado tienen un bajo poder y son operados en una mente relativamente alta y por lo tanto potencialmente peligrosa de temperatura (aproximadamente 90ºc). Una solución alternativa es la célula de combustible de ácido fórmico en este caso, las reacciones se producen a temperatura ambiente y el poder de estas células de combustible son claramente superiores a las de las de metanol. Además, el ácido fórmico es fácil de almacenar y transportar. Que, sin embargo, el combustible de ácido fórmico celulares estables en la operación que necesita un catalizador eficaz y duradero. Una ventaja del catalizador desarrollado en el PAS de la CIP, particularmente importante desde el punto de vista económico, es que conserva sus propiedades, mientras que operaban en el ácido fórmico de baja pureza. Ácido fórmico como puede ser fácilmente producido en grandes cantidades, también a partir de biomasa, por lo que el combustible para las células de combustible nuevo sería muy barato Clasificación de los conectores however: restricción due to: causales and: aditivo in addition: : restricción the new catalyst is cheaper than othercatalysts. this catalyst produces more formic acid large quantitie.
