Abstract: We give the characteristics of a hollow electrode discharge in oxygen in the presence of plasma created by an electron beam in the vicinity of the hollow entrance. Electron beam evaporates ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

In this study, chiral gold nanoparticles with a concave vortex cube structure were employed as the chiral substrate, exhibiting highly tunable optical chirality and intriguing chiral-induced spin ...

We report the infrared radiative capture of electrons at ionized oxygen donors in gallium phosphide. The radiative transition occurs between a shallow excited state (ionization energy 51.5±2 meV) and ...

The oxygen evolution reaction is crucial to sustainable electro- and photo-electrochemical approaches to chemical energy production (for example, H 2). Although mechanistic descriptions of the oxygen ...

The effective use of oxygen as an alloying element in Ti alloys is attractive due to the reduction of production cost and the increase in strength and hardness of the alloy. Although the oxygen ...

Water electrolysis is a main strategy for sustainable hydrogen production. The main obstacle limiting the efficiency of electrolytic water is the sluggish OER of four electron transfer steps.

About 510 million years ago, a deadly combination of low oxygen and surging hydrogen sulfide may have been what decimated 45% of all ocean life. When you purchase through links on our site, we may ...
