Proton exchange membrane (PEM) water electrolysis is an important technology to produce large-scale green hydrogen. Platinum ...

Chirality: like a right hand and a left hand, two molecules can have the same composition, but a different shape and ...

Electric vehicles may be the biggest topic in alternative fuels, but they're not alone: Hydrogen-powered engines have existed ...

The simultaneous generation of an electron beam with high energy and high current density with a high-fill factor is challenging for a backward wave oscillator (BWO) and other linear-beam devices. To ...

Just as we were getting used to electric supercars, along comes what is said to be the world's first hydrogen hypercar. The ...

Syllabus: The NTA has put the official JEE Main 2026 Syllabus online on their website: jeemain.nta.nic.in. If you're planning to take the JEE Main 2026 exam, you can find the full syllabus there. It ...

Using sunlight, rather than electrolysers, to split water into hydrogen has been a dream since the 1960s. A Fortescue-backed pilot plant is hoping to make that a commercial reality.

Generation of 23-fs-long laser pulses with energy of 8.5 μJ at the wavelength of 1.8 μm is achieved by means of Raman conversion of 250-fs 50-μJ pulses at the wavelength of 1.03 μm. The Raman ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has been getting bigger since the Big Bang. When the hydrogen and helium atoms ...

Substituent Effects on NMR Chemical Shifts and Cyclic Hydrogen Bonding in 2-Pyridone Dimers: An Accurate Approach to Hammett Constant Determination Linking Structure, Energetics, and Electron ...

Using density-functional theory, we predict stable alloy configurations (ground states) for a 1 nm Pt–Pd cuboctahedral nanoparticle across the entire composition range and demonstrate their use as ...
