(Phys.org)—Scientists have used sunlight to turn seawater (H2O) into hydrogen peroxide (H2O2), which can then be used in fuel cells to generate electricity. It is the first photocatalytic method of H2O2 production that ...
(Phys.org)—Although scientists know that when silicon mixes with water, hydrogen is produced through oxidation, no one expected how quickly silicon nanoparticles might perform this task. As a new study has revealed, 10-nm ...
(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For ...
Japanese scientist Kikunae Ikeda first proposed umami as a basic taste—in addition to sweet, sour, salty and bitter—in the early 1900s. About eight decades later, the scientific community officially agreed with him.
