“In a way, this mechanism is not too dissimilar to electron-hole recombination in semiconductor photodetectors,” exaplained Lozada-Hidalgo. While the mechanism may not be too different than semiconductor photodetectors, these devices are based on proton transport as opposed with all current photodetectors today, which are based on electron transport.
“One general philosophy for making something that can maintain high stress is to make it so strong that it’s unbreakable,” said Huang, professor of materials science and engineering in Northwestern’s McCormick School of Engineering.
When they illuminated the membrane with sunlight, they found the proton conductivity increased by 10 times, according to Dr Marcelo Lozada-Hidalgo, who led the research alongside Prof Sir Andre Geim.
A solar-driven photoelectrochemical cell provides a promising approach to enable the large-scale conversion and storage of solar energy, but requires the use of Earth-abundant materials.
Well, science could well be on its way to making us float too, thanks to a breakthrough in sonic levitation. Engineers from the University of Bristol have demonstrated that it’s possible to trap (essentially levitate) objects larger than the wavelength of sound in an acoustic tractor beam
