The H-Prize program is a series of inducement prizes intended to encourage research into the use of hydrogen as an energy carrier in a hydrogen economy...

The hydrogen economy is an umbrella term for the roles hydrogen can play alongside low-carbon electricity to reduce emissions of greenhouse gases. The...

Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel...

Deuterium (hydrogen-2, symbol 2H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other is protium, or hydrogen-1). The...

Fat hydrogenation is the process of combining unsaturated fat with hydrogen in order to partially or completely convert it into saturated fat. Typically...

This is a timeline of the history of hydrogen technology. c. 1520 – First recorded observation of hydrogen by Paracelsus through dissolution of metals...

2001 Nobel Prize in Chemistry. In 1956 a heterogeneous catalyst made of palladium deposited on silk was shown to effect asymmetric hydrogenation. Later,...

stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the Big Bang. As a predictive theory, it yields...

physicist who won the Nobel Prize in Physics in 1955 "for his discoveries concerning the fine structure of the hydrogen spectrum." The Nobel Committee...

Molecular hydrogen occurs in two isomeric forms, one with its two proton nuclear spins aligned parallel (orthohydrogen), the other with its two proton...

hyperfine energy levels of atomic hydrogen. Here is a brief description of how they work: First, a beam of atomic hydrogen is produced. This is done by submitting...

The parody has been used with other chemical names for water, such as hydrogen hydroxide, dihydrogen oxide, and hydric acid. It is also used in many prank...

Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride and the simplest pnictogen hydride, ammonia...

Hydrogen fuel enhancement is the process of using a mixture of hydrogen and conventional hydrocarbon fuel in an internal combustion engine, typically...

In chemistry, transfer hydrogenation is a chemical reaction involving the addition of hydrogen to a compound from a source other than molecular H2. It...

"gas dwarf" for a high-mass super-Earth-type planet composed mainly of hydrogen and helium in an animation of one model of the exoplanet Gliese 581c. The...

human. The moist solid emits small amounts of hydrogen cyanide due to hydrolysis (reaction with water). Hydrogen cyanide is often described as having an odor...

to an anomalous difference in energy between two electron orbitals in a hydrogen atom. The difference was not predicted by theory and it cannot be derived...

discovered the emission of a subatomic particle which he initially called the "hydrogen atom", but later (more accurately) named the proton. He is also credited...

The Nobel Prize in Physics (Swedish: Nobelpriset i fysik) is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields...
