Throughout the universe, hydrogen is mostly found in the atomic and plasma states whose properties are quite different from molecular hydrogen.

Atmosphere The outer atmosphere of Saturn contains 96.3 molecular hydrogen and 3.25 helium by volume.

In this symbiosis, the nonmethanogenic anaerobes degrade the organic substance and produce among other things molecular hydrogen (H2).

A key difference compared to other biogeochemical cycles is that because of its low molecular weight hydrogen can leave Earth's atmosphere.

Proteins are separated according to isoelectric point (pH at which they have neutral net charge) in the first dimension, and according to their molecular weight in the second dimension.

The nearly neutral theory of molecular evolution is a modification of the neutral theory of molecular evolution that accounts for slightly advantageous or deleterious mutations at the molecular level.

Hydrogen stations Hydrogen stations which are not situated near a hydrogen pipeline get supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen trailers, liquid hydrogen tank trucks or dedicated onsite production.

The hydrogen economy is a proposed system of delivering energy using hydrogen.

Dehydrogenation is a chemical reaction that involves the removal of hydrogen from a molecule.

There is a need to expand and deepen the community of scientists and engineers who work on energy issues, for instance within the disciplines of physics, chemistry, biotechnology and the social and economic sciences.

It s very hard to explain this by molecular recognition.

Liquid hydrogen (LH2 or LH2) is the liquid state of the element hydrogen.

Gel permeation chromatography is used to determine the number average molecular weight, weight average molecular weight, and polydispersity.

The Great Hydrogen Hope

The mean molecular mass of air is 28.97 g mol.

Each has a molecular weight of approximately 50,000 Daltons.

It's between two isotopes of hydrogen, two kinds of hydrogen deuterium, which is heavy hydrogen, which you can get from seawater, and tritium which is super heavy hydrogen.

Other compounds detected in volcanic gases are oxygen (meteoric), hydrogen chloride, hydrogen fluoride, hydrogen bromide, nitrogen oxide (NOx), sulfur hexafluoride, carbonyl sulfide, and organic compounds.

That implies that the pressure of hydrogen gas is 1 bar and the activity of hydrogen ions in the solution is unity.

There are emission lines from hydrogen that fall outside of these series, such as the 21 cm line.

It has the molecular formula C14H14N2.HCl and a molecular weight of 246.73 g mol.

Assuming that the hydrogen atoms are uniformly distributed throughout the galaxy, each line of sight through the galaxy will reveal a hydrogen line.

Many higher molecular weight amines are, biologically, highly active.

A molecular sieve can adsorb water up to 22 of its own weight.

The quality of the sample is sufficient for research on molecular biology.

Water is comprised of oxygen and hydrogen.

A hydrogen maser, also known as hydrogen frequency standard, is a specific type of maser that uses the intrinsic properties of the hydrogen atom to serve as a precision frequency reference.

The explosion is created when the white dwarf accretes hydrogen from the companion star, building up mass until the hydrogen undergoes fusion.

And I thought molecular weight sounded much less nerdy than molar mass.

In contrast, molecular orbital theory has orbitals that cover the whole molecule.

It also reacts with the other halogens and absorbs hydrogen.

Algae produce hydrogen under certain conditions.

A hydrogen unit was provided from the Swiss company Oerlikon.

And for molecular programming, the question is how does your cell phone know when to stop growing?

He believed the rays to consist of streams of particles of ordinary molecular magnitude.

This is why this new particle accelerator is so exciting.

The hydrogen revolution has started, but with a slow burning fuse.

Hydrogen fluoride is a chemical compound with the chemical formula HF.

Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO42 ).

At this depth, the temperature is above the critical temperature, which for hydrogen is only 33 K (see hydrogen).

In its simplest incarnation, water is split into hydrogen and oxygen gases.

Oxidation of hydrogen sulfide produces elemental sulfur (S8), oxidation state 0.

Steam reforming Fossil fuels are the dominant source of industrial hydrogen.

A hydrogen station is a storage or filling station for hydrogen, usually located along a road or hydrogen highway, or at home as part of the distributed generation resources concept.

Resistance to the growing influence of molecular biology was especially evident in evolutionary biology.
