Scientists have made stable, highly light-sensitive crystals. A research team from Saudi Arabia and Canada ‘grew’ light-sensitive single crystals of methylammonium lead bromide, with potential optoelectronic properties. “These crystals, easy to scale up over an area of tens of square of centimetres, could potentially be used to fabricate high-performance commercial photodetectors,” says lead researcher […]
Study in India suggests that the toxic element is making people there more vulnerable to the disease visceral leishmaniasis In parts of the Indian subcontinent, the only source of drinking water is groundwater that naturally contains arsenic. Lacking the means to remove the toxic substance, millions of people in these regions succumb to arsenic poisoning […]
Researchers create ultrathin nanotubes that can be used in solar cells. A research team from Egypt and Qatar synthesized semiconducting ultrathin nanotubes made of titanium dioxide that generate light-induced current when exposed to simulated sunlight. The thin-walled tubes can be potentially useful for manufacturing solar cells. Nageh Allam and his colleagues from The American […]
