Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

He based his calculations on the hydrogen atom, and more specifically, on the time it takes for the spin of a hydrogen atom’s electron to change relative to its proton. It’s known as the ...

TU Delft researchers developed innovative hydrogen sensors for safe energy use in aviation, enhancing carbon neutrality with ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

Scanning transmission electron microscopy experiments have uncovered the structural changes a ruthenium catalyst undergoes ...

“And the problem with a hydrogen car, if something goes wrong, it’s like the atom bomb went off,” he said. “You’re not recognizable. They'll say, ‘We thought it was Marjorie Taylor ...

Green hydrogen: Big gaps between ambition and implementation Date: January 14, 2025 Source: Potsdam Institute for Climate Impact Research (PIK) Summary: In recent years, more than 60 countries ...
