Nano–Crystalline Mn–Ni–Co–O Thermistor Powder Prepared by Co–Precipitation Method
Powders, 2023 Here, we demonstrate that nano–sized Mn–Ni–Co–O powder can be prepared at a low temperature via a co–precipitation method. In this work, Mn2+ was partially oxidized to Mn3+ ions in an aqueous solution by adding an oxidizing agent (H2O2).

Hemostatic Comparison of a Polysaccharide Powder and a Gelatin Powder [PDF]
Journal of Investigative Surgery, 2018 Purpose/Aim: Powdered hemostats have been widely adopted for their ease-of-use; however, their efficacy has been limited resulting in applications restricted to low-level bleeds. This study investigates the use of bovine-derived gelatin particles (BGP) as a standalone hemostatic powder and compare BGP to commercially available microporous ...

Langmuir, 2013 We investigate the wicking in granular media by considering layers of grains at the surface of a liquid and discuss the critical contact angle below which spontaneous impregnation takes place. This angle is found to be on the order of 55° for monodisperse layers, significantly smaller than 90°, the threshold value for penetrating assemblies of tubes ...

Cookoff of Black Powder and Smokeless Powder
Propellants, Explosives, Pyrotechnics, 2021 AbstractWe have completed a series of both vented and sealed cookoff experiments of black powder and smokeless powder in our Sandia Instrumented Thermal Ignition (SITI) apparatus at bulk densities of 1078 and 729 kg/m3, respectively. The confining aluminum cylinder was ramped from room temperature to a set point temperature and then held at the ...
