Manganese metal was evaluated as a fuel for slow-burning delay compositions press-filled in aluminium or compaction-rolled
in lead tubes. Oxides of antimony, bismuth, copper, manganese and vanadium were considered as ...

Layered double hydroxides (LDHs) with high and tailorable UV-Vis-NIR absorption were prepared through transition
metal (TM) modification. The synthesis method used and amount of TM present were found to influence the ...

A novel intumescent additive was synthesized by neutralizing 3,5-diaminobenzoic acid hydrochloride
salt with ammonium dihydrogen phosphate. This compound, which melts at 257 °C, decomposes
concurrently to release carbon ...

(Wiley-Blackwell, 2013-03)
A novel method to simultaneously measure liquid-solid-mass-transfer and external wetting
efficiency was employed at column to particle ratios of 10, 6 and 3. Two prewetting
procedures representing the upper (Kan) and ...
