Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Combustion and propulsive characteristics of potential hybrid rocket propellant

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Presently, the advancements in the field of rockets and rocket propulsion has been done to such an extent where the mission success rate is surely more than its failure. This has also led to a need for much better efficient materials (propellants) that form a major part of the rockets.
