The current work aimed to fabricate a screen-printed graphite electrode (SPGE) modified by MnO2 nanorods (MnO2 NRs) for sensing hydrazine. Thus, facile protocol was adopted construct the that were subsequently applied modify SPGE surface directly. As-synthesized NRs/SPGE sensor exhibited strong behavior towards hydrazine, with large peak and small oxidation potential. This electrochemical in op...

We report on real-time electrochemical detection of individual DNA hybridization events at an electrode surface. The experiment is carried out in a microelectrochemical device configured with a working electrode modified with single-stranded DNA probe molecules. When a complementary DNA strand labelled with a catalyst hybridizes to the probe, an easily detectable electrocatalytic current is obs...

The influence of hydrazine reduction on metal dispersion, particle size distribution, and support morphology was investigated for a series of bimetallic Ru-AuiMgO catalysts. The catalysts were prepared by impregnation of MgO with chlorine-containing precursor salt solutions. Hydrazine reduction significantly lowered the residual chlorine content of the catalysts and allowed the formation of hig...

in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...

The interaction of hydrazine vapors with single-crystal germanium was studied by using the thermogravimetric method. article considers processes taking place on surface Ge up to formation Ge3N4 nitride, in particular, accumulation N2H4+H2O and their etching water vapor contained hydrazine.

Reaction of 1-oxo-1,2,3,4-tetrahydrocarbazoles 1a-e with hydrazine hydrate in absolute ethanol afforded N,N'-bis-carbazolylazine derivatives 2a-e. Treatment of compounds 1a-e with hydroxylamine hydrochloride in ethanol with a catalytic amount of pyridine resulted in the formation of 1-hydroxyimino-1,2,3,4-tetrahydrocarbazoles 3a-e. Reduction of 3 with hydrazine hydrate in the presence of pallad...

The germanium nitride and InP nanowires were grown using the pyrolytic decomposition products of hydrazine (N2H4), which was containing 3 mol.% H2O. In a separate set of experiments the quartz microbalance was used to study the interaction of water containing hydrazine with Ge sample in the temperature range of 450-650°C. It was established that up to 500°C only water molecules interact with Ge...

The nitro group in aromatic nitro compounds containing reducible substituents such as methyl, carboxylic acids and phenols, and halogens are selectively and rapidly reduced at room temperature to the corresponding amines in good yield by employing hydrazine glyoxylate in the presence of zinc powder or magnesium powder. It has been observed that hydrazine glyoxylate is more effective than hydraz...
