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

Oct. 13, 2021 — A new single-atom catalyst can produce hydrogen from urea at an exceptional rate. Liquid nitrogen quenching introduces tensile-strain on the surface of oxide support, stabilizing ...

Single-atom catalysts are at the cutting edge of catalysis research, offering a blend of high efficiency, selectivity, and sustainability. Single-atom catalysts are defined by their structure where ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

In a particle diagram, atoms are represented by a single coloured ... Here, the oxygen atom is red, carbon is black and hydrogen is white. Image caption, A ball-and-stick model of methane ...
