La cat\u00e1lisis electrost\u00e1tica (usando campos el\u00e9ctricos) es la forma menos desarrollada de la cat\u00e1lisis en qu\u00edmica sint\u00e9tica, debido a que los efectos electrost\u00e1ticos pueden ser fuertemente direccionales. Los investigadores en Espa\u00f1a y Australia resolvieron este problema mediante el uso de t\u00e9cnicas innovadoras basadas en microscop\u00eda de efecto t\u00fanel.<\/p>\n<p>\u201cNuestro microscopio STM modificado nos permite la captura directa de mol\u00e9culas individuales que reaccionan\u00bb, dice Albert C. Aragon\u00e8s, estudiante de doctorado en el IBEC y la UB y el primer autor del estudio.<\/p>\n<p>\u201cMediante el control de la orientaci\u00f3n de las mol\u00e9culas en relaci\u00f3n con el campo el\u00e9ctrico, hemos acelerado una reacci\u00f3n no-redox por primera vez\u201d, a\u00f1ade Ismael.<\/p>\n<p>\u00abEl uso de campos el\u00e9ctricos externos como \u00abcatalizador\u00bb implica que se puede lograr la s\u00edntesis de mol\u00e9culas que de otro modo no podr\u00edan llevarse a cabo de manera rentable en el laboratorio o en grandes instalaciones industriales\u00bb, agrega Nadim Darwish, investigador Marie-Curie en el IBEC y en la UB. \u00abEsto abre las puertas hacia la nueva tecnolog\u00eda qu\u00edmica\u00bb.<\/p>\n<p>&#8212;<\/p>\n<p><em><strong>Source paper:<\/strong> <\/em>Albert C.
