Reactive dynamics study of hypergolic bipropellants: monomethylhydrazine and dinitrogen tetroxide.

Specific Impulse and Ignition Delay Time Assessment for DMAZ with Liquid Oxidizers for an Upper Stage Rocket Engine

2-Dimethyl amino ethyl azide (DMAZ) has attracted much attention as a suitable liquid fuel replacement for monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) in propellant systems because, in contrast to these fuels, it is noncarcinogen. In this research, performance, and ignition delay time of DMAZ were studied with common liquid oxidizers such as inhibited red fuming n...

Electrophilic aromatic substitution reactions are of considerable importance in the production of fine chemicals. However, many traditional processes suffer serious disadvantages, including low selectivity for the desired product and the requirement for large quantities of mineral or Lewis acids as activators. Such acids cause corrosion and generate large volumes of spent reagents. Major effort...

Modeling the Vapor – Liquid Equilibrium and Association of Nitrogen Dioxide / Dinitrogen Tetroxide and Its Mixtures with Carbon Dioxide

Determination of monomethylhydrazine with a high-throughput, all-fiber near-infrared spectrometer based on an integrated acoustooptic tunable filter and an erbium-doped fiber amplifier.

A novel integrated acoustooptic tunable filter (IAOTF) has been developed. This tunable filter is based on the Bragg interactions between waveguide and surface acoustic waves. Compared to (bulk) AOTF, its advantage include all-fiber construction, smaller size, narrower spectral resolution (1.7 nm), higher diffraction efficiency (37%), and lower rf power requirement (150 mW). A relatively narrow...

معرفی ماده 1و5-دی‌آزا بای‌سیکلو [3.1.0] هگزان و مشتقات آن به عنوان سوخت‌های مایع نوین خودمشتعل

1,5-Diazabicyclo[3.1.0]hexane (DABH) is the unusual and highly energetic derivative of the diaziridine, because cis-diaziridines are thermodynamically less stable than the trans-isomers. therefore, the investigation of DABH molecule has practical importance besides fundamental research. Three possible conformations of DABH were considered: boat, chair, and twist. According to the published repo...
