Sentences with phrase «studies of hydrogen molecules»

Studies of hydrogen molecules in the Venusian atmosphere by NASA's Pioneer - Venus probe indicate that the planet once had liquid water on its surface, perhaps even expansive oceans.

Not exact matches

«The physical and chemical processes that follow radiolysis release molecular hydrogen (H2), which is a molecule of astrobiological interest,» said Alexis Bouquet, lead author of the study published in the May edition of Astrophysical Journal Letters.

Researchers can now study how water behaves when stripped of the hydrogen bonds that normally govern its properties, as well as the molecule's two different «spin» states, which can not be separated when water molecules are en masse.

Scientists are using a pioneering method of «caging» and cooling water molecules to study the change in orientation of the magnetic nuclei at the centre of each hydrogen atom — a process which transforms the molecule from one form of water to another.

In this latest study from a team of physicists at the University of Edinburgh, researchers used a pair of diamonds to squeeze hydrogen molecules to record pressures, while analysing their behaviour.

Seeing hydrogen is critical to studying protonation states of an enzyme and ligand — a molecule that binds to a biological macromolecule — and to analyzing the architecture of hydrogen - bonding networks.

In an experiment conducted at the Linac Coherent Light Source, the team studied plastic simulating compounds formed from methane — a molecule with just one carbon bound to four hydrogen atoms that causes the distinct blue cast of Neptune.

A JCAP study shows that nearly 90 - percent of the electrons generated by a semiconductor / cobaloxime hybrid catalyst designed to store solar energy in hydrogen are being stored in their intended target molecules.

In one study, Mao and colleagues subjected a mixture of hydrogen and water to a pressure of about 220 megapascals (2,000 times atmospheric pressure) at room temperature (300 K or 80 °F), which formed a clathrate hydrate — a cage - like framework of water molecules enclosing molecules of gas.

When I was a physicist, back in the days when supercomputers had as much power as a cellphone, those of us who studied orientational forces between molecules of hydrogen or nitrogen used spherical harmonics to represent the behaviors (shperoidal wave functions, actually, since it is a quantum - mechanical problem).

A new study by Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis (JCAP) shows that nearly 90 - percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules.
