Ammonia is the most basic raw material in industrial and agricultural production. The current production of ammonia relies on Haber-Bosch process with high energy consumption. To overcome this shortcoming, development electrocatalytic synthesis under moderate conditions considered as a potential alternative technology. two-dimensional (2D) MXenes family has been proved promising electrocatalyst...

No one of the methods proposed for the synthesis of aspartic acid is entirely satisfactory as a practical procedure. The synthesis, described in a recent paper (1) from this laboratory, has been utilized in preparing 50 to 60 gm. lots of recrystallized aspartic acid but even here the beginning reagents are expensive, the over-all yield is only about 30 per cent of the theoretical, and the proce...

The climbing perch, Anabas testudineus, inhabits large rivers, canals, stagnant water bodies, swamps and estuaries, where it can be confronted with aerial exposure during the dry season. This study aimed to examine nitrogen excretion and metabolism in this fish during 4 days of emersion. Contrary to previous reports, A. testudineus does not possess a functional hepatic ornithineurea cycle becau...

Administration of arginine or a high-protein diet increases the hepatic content of N-acetylglutamate (NAG) and the synthesis of urea. However, the underlying mechanism is unknown. We have explored the hypothesis that agmatine, a metabolite of arginine, may stimulate NAG synthesis and, thereby, urea synthesis. We tested this hypothesis in a liver perfusion system to determine 1) the metabolism o...

Herein, a heterostructure of Ni 3 S 2 –Ni N was prepared by three-step synthesis procedure that consists the formation on NF, electrodeposition Ni(OH) over and nitridation in presence ammonia.

This is Part II of an overview the state-of-the-art and emerging technologies for decarbonising shipping using ammonia as a fuel. I (1) covered general properties ammonia, current production with emphasis on green synthesis methods, onboard storage ways to generate power from it. The safety environmental aspects, well challenges adaptation technology maritime structure, insight level costs duri...

A partially purified enzyme extract from lectin-transformed human peripheral blood lymphocytes synthesized purine nucleotides de nouo. Although the relatively lower specific activity of the pathway compared with that in the avian liver preparation previously described (Rowe, P. B., McCairns, E., Madsen, G., Sauer, D., and Elliott, H. (1978) J. Biol. Chem. 253, 7711-7721) limited the extent of p...

Ammonia synthesis via the high-temperature and high-pressure Haber-Bosch process is one of most important chemical processes in world. In spite numerous attempts over last 100 years, continuous type ammonia at room-temperature had not been possible, yet. We report development a mechanocatalytic system operating continuously pressures down to 1 bar. With optimized experimental conditions, cesium...
