2017-2-25 · ABSTRACT: The INO experiment is a mega-science project and will have RPC detectors as an active element. It will be instrumented with about 28,800 RPC detectors. These active detectors use a gas mixture of R134a (95.2%), Isobutane (4.5%) and SF6 (0.3%).

Rational Electrode–Electrolyte Design for Efficient

2018-4-25 · Renewable energy-driven ammonia electrosynthesis by N2 reduction reaction (NRR) at aient conditions is vital for sustainability of both the global population and energy demand. However, NRR under aient conditions to date has been plagued with a low yield rate and selectivity (<10%) due to the more favorable hydrogen evolution reaction (HER) in aqueous media.

Abstract. High-voltage circuit breakers (HVCB) generally act in pure SF 6 under pressure of a few bars. the wong of this kind of circuit-breaker consists first to create an electric arc due to the separation of the contacts and second to rapidly extinguish this arc by a high blowing during the current-zero phase of the alternative current. for a given gas, the rate of transition from the
