Schlieren visualization of detonation diffraction and initiation in B/C2H4/O2 heterogeneous mixtures using a variable-initial pressure pre-detonator tube

Solid powder detonation engines hold significant potential for enhancing aerospace propulsion performance, owing to the high volumetric energy density of solid fuels and the high thermal efficiency of the detonation cycle. These engines are typically ignited by a pre-detonator tu...

Low InterfacialContact Resistance between Carbon-BasedGas Diffusion Layer and Sputter-Deposited Anatase TiO2

Abstract Reducing the interfacial contact resistance between separators and gas diffusion layers is critical for achieving high-power polymer-electrolyte membrane fuel cells. Stringent targets for contact resistance below 3.0 mΩ cm2 have been proposed; however, achieving such val...
