Structural and Metabolic Studies of Glycosaminoglycans (Sulfatase, Hydrazine, Mucopolysaccharidosis)
… of the N-acetylhexosamine residues with hydrazine (N(,2)H(,4)) followed by nitrous acid (HONO) cleavage of the polymer at pH 4.0. Initial studies with heparin-derived model compounds indicated that ester and N-sulfate substituents were stable during N(,2)H(,4) treatment but that uronic …

The detection of hydrazine and related materials by ion mobility spectrometry.
… years, has been shown to be capable of detecting hydrazines at low concentrations but with interference from ammonia. Ammonia is usually present in hydrazine environments, as a breakdown product or a by-product of the human metabolism. This project was undertaken to investigate mechanical and …

Preparation of organic hydrazides
Due to the actual high price of hydrazine, this chemical cannot be used in an economical preparation of organic hydrazides. A synthesis of such hydrazides can be envisaged by the reduction of N-nitroamides. The problem is then to find a set of conditions under which no hydrogenolysis of the …

Synthesis and Electrocatalytic Properties of Structure Engineered First-Row Transition Metal Derivatives
… development, fuel cells using liquid fuels (e.g. hydrazine) need to be developed. The key to both water electrolysis and fuel cells is the electrocatalyst. Currently, the noble metal based materials are still the state-of-the-art electrocatalysts for water electrolysis and in fuel cells in terms …

CYCLIZATION-BASED SITE-SELECTIVE N-TERMINAL CYSTEINE CONJUGATION, PEPTIDE STAPLING AND HISTONE DEACETYLASE (HDAC) PROBING
… reports another cyclization reaction between hydrazine and carbamate, synthesized from 7-hdyroxy coumarin derivatives. We demonstrate that the secondary nitrogen of hydrazine is much more reactive than the primary nitrogen for intramolecular cyclization reactions. Hydrazine affords urea bonds …

Multifunctional oxidation electrocatalysts for direct alkaline fuel cells
… of novel electrocatalysts for the oxidation of hydrazine for application in direct hydrazine alkaline fuel cells. Hydrazine is a carbon-free nontraditional fuel with high energy density (5kWh/kg), which is often considered a green fuel since its oxidation only produces nitrogen and water and …
