Nitrogen fixation is the process where atmospheric nitrogen is converted into a reactive form by breaking the triple covalent bond between nitrogen atoms, allowing it to bond with other elements like carbon, hydrogen, and oxygen through the use of specialized enzymes in microorganisms or industrial pr...
Once the dioxygen is adsorbed via a C–O–O–C configuration, the introduction of the first electron-proton pair (i.e., the first reduction stage) leads to the dissociation of the O–O bond and the formation of one hydrogen bond between both oxygen atoms [117]. This mechanism also ...
The conformational linkage units preferably include conformational ring structures which exhibit hydrogen bonding or other Lewis acid-Lewis base type of interactions. The conformational ring structures can include hetero-atoms and cationic metal atoms. The chemical groups and bonding features of the polymer...
instrument. In its simplest form, adsorption involves the attraction and immobilization of a given solute molecule (adsorbate) on the surface of a solid (adsorbent) via physical (Van der Waals) and chemical (bond sharing) interactions. From a process standpoint, the cost of adsorption varies ...
Tungsten carbide is one of the most promising electrocatalysts for the hydrogen evolution reaction, although it exhibits sluggish kinetics due to a strong tungsten-hydrogen bond. In addition, tungsten carbide’s catalytic activity toward the oxygen
of energy to proceed (Postgate 1982). The nitrogen molecule is composed of two nitrogen atoms joined by a triple covalent bond, thus making the molecule highly inert and nonreactive. Nitrogenase catalyzes the breaking of this bond and the addition of three hydrogen atoms to each nitrogen atom....
Engineering of defects in semiconductors provides an effective protocol for improving photocatalytic N2conversion efficiency. This review focuses on the state-of-the-art progress in defect engineering of photocatalysts for the N2reduction toward ammonia. The basic principles and mechanisms of thermal catalyz...
By using molecular modeling we have found a hydrogen bond in the transition state for protease/amidase catalyzed hydrolysis of peptides and amides donated by the scissile NH-group of the substrate. The hydrogen-bond acceptor was found either in the enzyme (enzyme assisted) or in the substrate ...
