Sentences with word «photolysis»

Predicted anvil mixing ratios of the soluble species, HNO3, H2O2, and CH2O, exhibit significant differences among models, attributed to different schemes in these models of cloud processing including the role of the ice phase, the impact of cloud - modified photolysis rates on the chemistry, and the representation of the species chemical reactivity.

Primary Petrochemical Processes in photolysis mediated by humic substances.

It is believed water photolysis occurred on these planets, giving hydrogen and oxygen.

The effects of methane photolysis and the subsequent organic haze would allow for absorption and remission of solar energy at that level which would in turn cool the surface, we have a very nice model planet showing this Titan.

The researchers also observed that the formation of functional microcircuits was determined by the specific settings (action potentials induced by repetitive glutamate photolysis) used during stimulation.

The researchers used a 2 - photon photolysis technique that can be performed in vivo, together with imaging, to manipulate and monitor neuronal activity at single - cell resolution.

They created the biradical, carbonyl oxide, by bombarding diiodomethane with ultraviolet photons in a process known as photolysis.

Steven Reiken, a research fellow in the department of surgery at the Massachusetts General Hospital in Boston, believes that antibody - targeted photolysis (ATPL), a technique based on a procedure used to treat some cancerous tumours, could cure infections caused by P. aeruginosa.

Quentin H. Gibson, who is best known for his pioneering work on the kinetics of ligand binding to hemoglobins and the development of stopped flow and flash photolysis instruments, passed away on March 16, 2011 in Hanover, N.H., at the age of 92.

The rapid photolysis of Cl2O2 is a key reaction in the chemical model of ozone destruction developed 20 years ago2 (see graphic).

CO2 photolysis in both cases provides a low level of free O2, but in this case there is no overall effect.

But Catling's team proposes instead that the hydrogen escaped into space through a process called methane photolysis, in which the hydrogen - containing methane reacts with oxygen such that hydrogen atoms are freed.

This water photolysis must have happened to the primordial Earth, with loss of Hydrogen to space but it was stopped, as it is today, by the presence of ozone (O3) which requires high oxygen tension to form and it quickly reoxidises hydrogen via OH hydroxyls back to water.

Photolysis of DM - nitrophen increased [Ca2 +] i from resting concentrations of 20 - 50 nM to values above microM, as measured with the fluorescent indicator Fluo - 3.

So far we have only been able to detect the presence of some of the simpler amino acids in our photolysis residues.

The basic idea is that Cl catalyzes conversion of ozone, O3 to molecular oxygen, O2 (1) Cl + O3 — > ClO + O2 (2) ClO + O3 — > Cl + 2O2 ClO can dimerize (3) ClO + ClO — > ClOOCl which removes it from the catalytic cycle (1) and (2), but it can also be photolyzed (4) ClOOCl + hv — > ClO + ClO so the rate of photolysis, which is proportional to the absorption cross-section, determines how much ClO is available for the cycle.
