Water Electrolysis with Inductive Voltage Pulses

“…The studies of HER are carried out in different kind of systems and following each other processes is divided (Salem, 2004;Heyrovsky, 2006;Murphy, 1983;Bockris, 1957;El-Meligi, 2009;Sasaki and Matsuda, 1981;Noel and Vasu, 1990;Kristalik, 1965): Volmer electrochemical discharge step, Heyrovsky electrochemical desorption step, Tafel catalytic recombination step. Each of steps can be a reaction limiting step in a certain system during the whole reaction.…”

A sensor for investigating the interaction between biologically important heavy metals and glutathione

“…Capillary electrophoresis (CE) or high-performance liquid chromatography (HPLC) are the most commonly used techniques for GSH separation. For the identification and determination of GSH and other related peptides and proteins electrochemical methods based on the catalytic evolution of hydrogen on mercury electrodes (peak H, Brdicka procedure) have been intensively used (Heyrovský, 2000(Heyrovský, , 2004(Heyrovský, , 2006Kizek et al, 2001;Mader et al, 2001;Brázdová et al 2002;Trnková et al, 2002;Strouhal et al, 2003;Průša et al, 2004aPrůša et al, ,b, 2005Průša et al, , 2006aKukačka et al, 2006). Electrochemical techniques appeared to be very suitable for the design of sensors and biosensors (Billová et al, 2003;Kizek et al, 2003;Vacek et al, 2004a;Adam et al, 2005a,b,c;Potěšil et al, 2005Potěšil et al, , 2006.…”
