For their excellent features like their low energy consumption, long lifetime, minimal environmental pollution and high efficiency the white light emitting diodes represent an attractive alternative to conventional sources of artificial lighting. Therefore, the interest optimize their components and include the development of new elements with better characteristics has increased...
Cyanidation is the most commonly used process in the world for extracting silver from its ores. In recent years, mineral deposits with easily leachable silver are being depleted. On the other hand, there is an abundance of silver sulfosalts (thioarsenites and thioantimonites), which are difficult to dissolve with cyanide and...
El trabajo presenta el estudio fotocrómico de los diariletenos 1,2-diciano1,2-bis(2,4,5-trimetiltiofen-3-ilo)etano (D1) y 1,2-bis(5-etoxi-2-(2-piridilo)tiazolilo)perfluorociclopenteno (D2); y la síntesis y luminiscencia del co-(estireno-vinilanilina) dopado con dos nitronaftalimidas (PStV3N y PStV4N respectivamente). El estudio fotocrómico de D1 se realizó en solución de tetraclorometano; D2 se estudió en estado sólido; se empleó la técnica...
Coupling TiO2 with other oxides is an efficient strategy employed to increase the photocatalytic performance of the TiO2. The composite offers a pathway to separate charge carriers by suppressing their recombination. Commonly, a maximum performance is observed when the foreign oxide is around 5-7 % mol in the composite, leading...
