Experiments and Modeling of the Autoignition of Methyl-Cyclohexane at High Pressure [PDF]
arXiv, 2017 The autoignition delays of mixtures of methyl-cyclohexane (MCH), oxygen, nitrogen, and argon have been studied in a heated rapid compression machine under the conditions $P_C$ = 50 bar, $T_C$ = 690 - 910K. Three different mixture compositions were studied, with equivalence ratios ranging from $\phi$ = 0.5 - 1.5.

Experimentally demonstration of the repulsive Casimir force in the gold-cyclohexane-PTFE system [PDF]
arXiv, 2019 The experimentally demonstration of Casimir force transition from attraction to repulsion is still challenging. Herein, the Casimir forces for a sphere above a plate immersed in different liquids were precisely measured using Atomic force microscope, and the long-range repulsive Casimir force in the gold-cyclohexane-PTFE system is observed for the ...

Photosynthesis of NH3 from NO3− Using CH4 in Homogenous Rhenium Catalysis
Angewandte Chemie, EarlyView.We present a Re catalysis of one‐pot synthesis of NH3 from NO3− using CH4 as a reductant under UV light irradiation. We are able to directly convert NO3−, leading to several environmental issues, to NH3, an essential compound as a fertilizer and industrial raw material, by means of CH4, which has a high affinity with renewable resource/energy, as a ...
