Experiments have been performed upon the absorption of ammonia and hydrazine from different solutions instilled into a human ileal sac with an exteriorized stoma. Ammonia and hydrazine absorption was greater from solutions of higher pH. It is concluded that non-ionic diffusion plays an important role in ammonia absorption from the human ileum.

Hydrazine borane N2H4BH3 and alkali derivatives (i.e., lithium, sodium and potassium hydrazinidoboranes MN2H3BH3 with M = Li, Na and K) have been considered as potential chemical hydrogen storage materials. They belong to the family of boronand nitrogen-based materials and the present article aims at providing a timely review while focusing on fundamentals so that their effective potential in t...

reasonable to suppose that the ratio k(Gly. Gly)/ kl(Leu. Gly) gives an approximate estimate of the relative selectivities of the reagents towards the splitting of peptide bonds. A simple calculation from the results in Table 2 gives a value of the ratio of 5 for aqueous hydrochloric acid and average values of 16 for methylhydrazine and 22 for hydrazine. Therefore the selectivity of the reagent...

A novel addition reaction of an aromatic hydrazine to the diketone derivative of C60 occurs highly regioselectively with an unusual migration of two hydrogen atoms from the hydrazine to the fullerene and affords a fluorescent product having a methylene carbon along the orifice.

The title compound, C(28)H(30)N(2)P(2), adopts a well documented and studied gauche conformation around the hydrazine bond. Bond lengths and angles are in the typical ranges expected for P-N and P-C bonds. A normal hydrazine N-N bond length of 1.426 (3) Å is observed.

Ultrathin 2D metal alloy nanomaterials have great potential applications but their controlled syntheses are limited to few noble metal based systems. Herein Ni x Co1-x alloy nanosheets with ultrathin (sub-3 nm) single-crystalline 2D structure are synthesized through a topochemical reduction method. Moreover, the optimized composition Ni0.6Co0.4 alloy nanosheets array exhibits excellent performa...

Within recent years hydrazine and the methyl substituted hydrazines have come into considerable use as rocket fuels. As a result of this increased production of hydrazines, the possibility of accidental human exposure is of considerable interest. Obvious concern results from the fact that hydrazine had been used as an experimental means of producing fatty liver in experimental animals for many ...

a thin film of epinephrine (ep) was electrochemically deposited on the surface of glassy carbon electrode previously activated in nahco3 solution. the cyclic voltammograms of the modified electrode indicate that the surface confined ep are strongly dependent on the solution ph, as expected for quinone/hydroquinone functionalities. the ep-modified glassy carbon electrode exhibited catalytic acti...

Some new hydrazono 5a,b, thiosemicarbazono 6a-c, and oximo chromenes 7a-c were prepared via the reaction of the corresponding beta-chlorocarbaldehyde 3 with hydrazine, aromatic hydrazine, thiosemicarbazide and hydroxylamine hydrochloride, respectively. In addition, ether derivatives 8a-h were prepared from the corresponding aldoximes 7a-c. The new products were tested for anti-inflammatory and ...
