Degradation of explosives by nitrate ester reductases.
Explosive-contaminated land poses a hazard both to the environment and to human health. Microbial enzymes, either in their native or heterologous hosts, are a powerful and low-cost tool for eliminating this environmental hazard. As many explosives have only been present in the environment for 10 years, and with similar molecules not known in Nature, the origin of enzymes specialized for the bre...

An SEM and EDS study of the microstructure of nitrate ester plasticized polyether propellants
To p robe the microstructures of ni trate est er pla sticized p olyether (NEPE) composite propellants and observe th e morphology of each constit ute in the propellant, the microstructure and elemental constitutes of NEPE propellants were investigated using scanning electron microscopy and energy dispersive X-ray spectroscopy. The ammonium perchlorate (AP) grains had a scraggy surface and were ...
متن کاملSynthesis of Magnetic Iron-Oxide Nanofiber Composite using Electrospinning: An Absorbent for Removal of Nitrate from Aqueous Solution
This project is aimed at preparation of nano filters using recycled foam of food containersenriched by magnetic nanoparticles, for nitrate removal from water. The characterization ofthis electrospun magnetic nanofiber depicted a high capacity for nitrate adsorption. TheScanning Electron Microscopy (SEM), X-Ray powder Diffraction (XRD), Energy DispersiveSpectrometry (EDAX) and Inductively Couple...
متن کاملRegioselective synthesis of cellulose ester homopolymers.
Regioselective synthesis of cellulose esters is extremely difficult due to the small reactivity differences between cellulose hydroxyl groups, small differences in steric demand between acyl moieties of interest, and the difficulty of attaching and detaching many protecting groups in the presence of cellulose ester moieties without removing the ester groups. Yet the synthesis of homopolymers of...
