Burn rate of a novel boron-AN-water green solid propellant
FirePhysChem, 2022 A novel composition of green solid rocket propellant has been suggested and examined. Boron powder was chosen to serve as fuel, for its very high energetic potential, which exceeds that of other common metals, as well as that of fossil fuels.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
