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...

In the title compound, C12H11N3O, the C=N imino bond is in an E conformation. In the crystal, adjacent mol-ecules are linked by N-H⋯Ncyano hydrogen bonds, forming a chain running along [110].

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 ...

As part of continued efforts to understand the mechanisms of 1,5-α-l-arabinanases better, some arabinan-like iminosugar oligosaccharides were synthesized. An iminosugar analogue of arabinobiose was found to be a good inhibitor of the arabinanase Arb93A from Fusarium graminearum. Structures were determined for complexes of this inhibitor with wild-type Arb93A and a catalytically inactive mutant.

In the title complex, [Ni(C(9)H(9)BrNO)(2)], the Ni(II) ion lies on an inversion centre and is coordinated in a slightly distorted square-planar geometry by two N atoms and two O atoms from two symmetry-related bidentate 4-bromo-2-(ethyl-imino-meth-yl)phenolate ligands. The complex forms a one-dimensional chain in the crystal structure through short C-H⋯Br contacts (H⋯Br = 3.009 Å).
