Lead-free, more efficient solar cells and other optoelectronics devices will likely be based on a family of materials known as hybrid perovskites. Scientists identified how to control different properties and stability in these solar cell materials using lead-free preparation.
Someday, chemically protective suits made of fabric coated in self-healing, thin films may prevent farmers from exposure to organophosphate pesticides, soldiers from chemical or biological attacks in the field and factory workers from accidental releases of toxic materials, according to a team of researchers.
While 'go big' is the motto for many science initiatives, researchers are hoping a cutting-edge microscope will allow them to 'go deep' to promote biomedical research and discoveries in materials science.
A combined experimental and theoretical study comprising researchers has shed new light on the behaviour of individual gold atoms supported on defective thin cerium dioxide films - an important system for catalysis and the generation of clean hydrogen for fuel.
Researchers explored the properties of a promising class of materials with new capabilities that depend on cracks. Their results could help open the way for practical applications from nonvolatile computer memory to quick-dimming windows.
