(Phys.org)—Splitting water is a two-step process, and in a new study, researchers have performed one of these steps (reduction) with 100% efficiency. The results shatter the previous record of 60% for hydrogen production ...
(Phys.org)—Photosynthesis – the ubiquitous yet remarkable process by which most plants, algae, and cyanobacteria convert light energy into chemical energy – provides the atmospheric oxygen and organic compounds fundamental ...
(Phys.org) —Scientists have long observed that the wettability of graphene – an essentially two-dimensional crystalline allotrope of carbon that it interacts oddly with light and with other materials – can be reversed ...
(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 ...
The absorption of water waves is the process through which water waves lose their energy, thus reducing their impact on shores or other solid structures surrounding them. Enabling this absorption process in real-world settings ...
A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That's because, even though hydrogen is abundant, it must be derived from another substance that contains ...

A large international team of researchers has proven that fragments of splitting atomic nuclei begin spinning after scission occurs during nuclear fission. In their paper published in the journal Nature, the group describes ...
The search for sustainable approaches to generating new fuels has brought scientists back to one of the most abundant materials on Earth—reddish iron oxide in the form of hematite, also known as rust.
