Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

NUMERICAL STUDY AND REMEDIATION OF AC INTERFERENCE CORROSION ON NEIGHBOURING PIPELINES [PDF]
Journal of Engineering Science and Technology, 2018 Buried pipelines for gas and oil are protected by an insulation coating and a Cathodic Protection (CP). However, neighbouring high voltage HV power lines induce an alternating current AC which causes corrosion damages on metallic structures, even in CP ...
