We present the results of two-and three-dimensional calculations of turbulent nuclear burning of hydrogen-rich material accreted onto a white dwarf of 1.0 M. The main aim of the present paper is to investigate the question as to whether and how the general properties of the burning are aaected by dimension-ality and numerical resolution eeects. In particular, we want to see whether or not conve...

The transition from natural gas to renewable gases such as biogas and hydrogen creates an interchangeability challenge. laminar flame speed SL is a critical parameter in appliance design it unique characteristic of the mixture. It thus essential evaluate impact on SL. In this work, 1D simulations were conducted Cantera with USC-Mech 2.0 kinetic mechanism. three base blends (BG100, BG90 BG80) wa...

Hydrogen served as an electron donor in the reductive dechlorination of tetrachloroethene to vinyl chloride and ethene over periods of 14 to 40 days in anaerobic enrichment cultures; however, sustained dechlorination for more extended periods required the addition of filtered supernatant from a methanol-fed culture. This result suggests a nutritional dependency of hydrogen-utilizing dechlorinat...

Currently there is intense interest in decreasing the operating potential for hydrogen evolution in water electrolysis to considerably decrease the energy cost. In this work we report a significant decrease of the operating potential for hydrogen evolution from neutral water mediated by an iron based soft coordination polymer (Fe(III)-SCSP). The creation of a local acidic environment with a thi...

We investigated the multichannel reaction of ground-state carbon atoms with acetylene, C2H2 (X1Sigmag+), to form the linear and cyclic C3H isomers (atomic hydrogen elimination pathway) as well as tricarbon plus molecular hydrogen. The experiments were conducted under single-collision conditions at three different collision energies between 8.0 kJ mol-1 and 31.0 kJ mol-1. Our studies were comple...
