Hydrogen explained - U.S. Energy Information Administration (EIA)
Hydrogen occurs naturally on earth in compound form with other elements in liquids, gases, or solids. Hydrogen combined with oxygen is water (H 2 O). Hydrogen combined with carbon forms different â¦
Hydrogen | Properties, Uses, & Facts | Britannica
Feb 27, 2026 · The earliest known chemical property of hydrogen is that it burns with oxygen to form water; indeed, the name hydrogen is derived from Greek words meaning âmaker of water.â
Wormhole Model for Neon-20
A quantum mechanical model for the Neon-20 nucleus is developed that allows for the splitting of a bipyramidal structure of five alpha-partices into an alpha-particle and an Oxygen-16 nucleus. The geometry of the configuration space is assumed to be...
Are all Hydrogen-powered vehicles essentially a scam?
My understanding of hydrogen powered vehicles is that you fill the "fuel tank" with water, and then the car or bike separates the oxygen and hydrogen via electrolysis. As far as I know, nobody is mini...
I figured out a reactor design that does it all! Variable heat output of ~10 or ~25 Steam…
This reactor is fed 5 g/s of water at \~ 430°C, and 101 grams of enriched uranium every 6 seconds, keeping the fuel between 400-600 grams during operation while dumping 100 kg of \~2000 °C nuclear w...
Decoupled Water Splitting: From Basic Science to Application
In this review, we discuss disruptive decoupled water splitting schemes, in which the concurrent production of hydrogen and oxygen in close proximity to each other in conventional electrolysis is replaced by time- or space-separated hydrogen and oxyg...
Superconductivity in the vicinity of ferromagnetism in oxygen free perovskite MgCNi3: An e…
We report synthesis, structural, magnetic, specific heat and Density Functional Theory (DFT) studies on MgCNi3 superconductor. Polycrystalline MgCNi3 samples are synthesized through standard solid state reaction route and found to crystallize in cubi...

The development of deep-ocean anoxia in a comprehensive ocean phosphorus model
We analyse a model of the phosphorus cycle in the ocean given by Slomp and Van Cappellen (2007, https://doi.org/10.5194/bg-4-155-2007). This model contains four distinct oceanic basins and includes relevant parts of the water, carbon and oxygen cycle...
