The catalytic formation of ammonia synthesis through dimers N molecule. The most interesting feature of this model is it yields a steady reactive window, which is separated by continuous and discontinuous irreversible phase transitions. The phase diagram is qualitatively similar to well-known ZGB model...
46 predicting plastic and superionic helium-ammonia compounds at extreme condition. They predicted three stable stoichiometries and eight new stable phases of He–NH3 compounds under pressures up to 500 GPa and found that the predicted He–NH3 compounds exhibit superionic behavior at high pressure ...
It is vital to design effective nitrogen fixation systems that operate under mild conditions, and to this end we recently reported an example of the catalytic formation of ammonia using a dinitrogen-bridged dimolybdenum complex bearing a pincer ligand, w
View Solution Explain diagrammatically the lone pair effect of [a] The nitrogen atom of the ammonia molecule leading to the formation of ammonium ions[NH4]+ [b] The oxygen atom of theH2Omolecule leading to formation of hydronium[H3O+]& hydroxyl ions[OH]− ...
At 60°C the highest concentrations of this imidazoline were measured at pH 9. With increasing temperature the pH-optimum of the imidazoline formation shifted to lower pH levels.The reaction of N α -acetyl-dehydroalanine-methylester with ammonia generated β-aminoalaninoalanine, which was ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Supported by theoretical calculations, it is suggested that the improved dehydrogenation properties of metal amidoborane ammoniates compared to metal amidoboranes are a result of the participation of a strong dihydrogen bond between the NH3 molecule and [NH2BH3]. Our study elucidates the reaction ...
nucleation involves sulfuric acid (H2SO4) over almost all the troposphere8. However, binary nucleation of H2SO4–H2O is slow and, so, ternary or multicomponent nucleation with extra vapours such as ammonia (NH3)9and organics10,11is necessary to account for observed new-particle-formation rates...
(ligancy > 2) in a molecule together with all of its ligands.” The basic premise of GA scheme is that one can subdivide an arbitrary chemical compound into a set of smaller structural units in such a way that the overall thermodynamics of that compound can be calculated from thermodynamics...
The chemically induced crosslinks are between lysine and glutamic acid or lysine and aspartic acid with release of a molecule of water. The transglutaminase induced crosslinks are between lysine and glutamine with release of a molecule of ammonia. Protein aggregates in neurodegenerative diseases are ...
