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 ...

In the title compound, C(5)H(8)N(3) (+)·Cl(-), the cation and the anion lie on a mirror plane and are hydrogen bonded in a three-dimensional network via the H atoms of the two hydrazine N atoms. The pyridine N atom is protonated and hydrogen bonded to the terminal hydrazine N atom.

We controlled the morphologies of zinc oxide (ZnO) nanostructures on single-walled carbon nanotube electrodes by an electrochemical deposition method and investigated the dependence of the electrocatalytic characteristics toward hydrazine on the different morphologies. ZnO nanorods provided high electrocatalytic activity with unique electrochemical behaviours, associated with the H(+) ion gener...

I would like to comment briefly on the issue raised by Dr. Wheeler (1) with reference to the review by Tisdale (2) on the use of hydrazine sulfate for the treatment of patients with cancer cachexia. The point, in my opinion, is not whether or not hydrazine sulfate was effective in the clinical trials reported by the authors but whether its use in that context was appropriate. We know, in fact, ...
