Solid propellants: AP/HTPB composite propellants
Arabian Journal of Chemistry, 2019 AbstractIn this article we mainly discuss about AP/HTPB composite solid propellants. Classification, components, properties, burning rate and ignition behavior of propellants are mentioned here. Combustion of AP monopropellant, HTPB and AP/HTPB is discussed in detail.

The Passage of Chaperonins to Extracellular Locations in Legionella pneumophila Requires a Functional Dot/Icm System [PDF]
BiomoleculesHtpB, the chaperonin of the bacterial pathogen L. pneumophila, is found in extracellular locations, even the cytoplasm of host cells. Although chaperonins have an essential cytoplasmic function in protein folding, HtpB exits the cytoplasm to perform ...
