However, computations predict that the charge distribution of NO3À is anisotropic and minimal on nitrogen. Here we show that when the nitrate's charge is suffi- ciently dampened by resonating over a larger area, a Lewis acidic site emerges on nitrogen that can interact favourably with ...
(only in the presence of a catalyst under pressure and at high temperature): 2P 6H2O = 2HPO35H2. Water does not react with nitrogen and hydrogen, but with carbon at high temperatures it gives water vapor: C + H2O = CO + H2. The reaction can be used both in the industrial ...
Moreover, the type2 enterotypes had higher serum ornithine, which indicates a stronger urea cycle of the body [51]. For ruminants, the urea cycle could provide more urea nitrogen for rumen microbial protein [52]. In the milk, increased palmitoyl-L-carnitine in the type2 enterotypes could ...
“With this material, the dawn of ambient superconductivity and applied technologies has arrived,” according to a team led by Ranga Dias, now an assistant professor of mechanical engineering and of physics. The researchers have discovered that nitrogen-doped lutetium hydr...
The prototype chemical treatment for cancer was a nitrogen mustard(HN2). Like most chemotherapy agents, it works by killing cells. That sounds like a bad thing, but it turns out to be a good thing if the victims are cancerous cells. HN2’s cytotoxicity is due to its ability to alkylate...
Scientists from the RIKEN Nishina Center for Accelerator-Based Science and collaborators have shown that knocking out a single proton from a fluorine nucleus—transforming it into a neutron-rich isotope of oxygen—can have a major effect on the state of
These single and double bonds have relatively low bond energies (approximately 160 and 418 kJ/mol, respectively) compared with triple bonds (954 kJ/mol) [1]. Thus, single- or double-bonded polymeric nitrogen can release a large amount of energy upon dissociation into triple-bonded nitrogen ...
As the electrons hit the oxygen and nitrogen molecules, it "dumps in a little energy," Hampton said. "And then (the molecules) relax back down to ground state. When they do that, they release a little bit of light." The best chance of seeing the aurora is to head toward the poles,...
