A University of California, Berkeley chemist has engineered a new technology that could make hydrogen-producing fuel cells ...

Hydrogenases catalyze the reversible splitting and production of hydrogen gas (H2), using complex catalytic cofactors ...

A key objective of electronics engineers is to further reduce the size of devices, while also boosting their speed, ...

The force of gravity varies across the solar system, primarily influenced by a celestial body's mass, size, and density. The Sun has the strongest gravity at the centre, while planets like Jupiter ...

A covalent bond is formed when two atoms share one or more pairs of electrons to achieve a stable electron configuration.

This statement is generally false. Covalent compounds tend to have lower melting and boiling points compared to ionic ...

During winter months, frost can unleash icy havoc on cars, planes, heat pumps, and much more. But thermal defrosting with ...

One such question, asked every now and then, is why humans float more easily in saltwater. There are a few places in the world where this is especially apparent, for example in the Dead Sea, or in the ...

Figure 1. (a) Schematic diagram of the synthesis of TA-TMT, TA/DTTA-2-TMT, and DTTA-TMT; (b) PXRD patterns of TA-TMT, (c) TA/DTTA-2-TMT, and (d) DTTA-TMT. Inspired by the "barrel effect", the team ...

A hydroquinone-embedded covalent organic framework (Tz-QH-COF) was designed to address photocatalyst instability in solar-driven H₂O₂ production. The hydroquinone units serve as reversible hole ...
