The Synergistic Effect of Fe-Based MOFs and HTPB on AP Decomposition in Solid Propellants
SolidsMany factors and their mutual interaction between catalysts and AP/HTPB composite solid propellant induce the complexity in the combustion. Among them, we prepared two Fe-based MOFs as catalysts and investigated their catalytic effects and mechanism on ...

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 ...

Experimental evaluation of HTPB/paraffin fuel blends for hybrid rocket applications
Combustion and Flame, 2021 Hybrid rockets have many advantages over pure solid or liquid propellant rockets, but low solid fuel regression rates and correspondingly low thrust have hindered their application to operational systems. Paraffin-based fuels regress significantly faster
