Platinum therapies For half a century, the field of metalbased anticancer drugs has been dominated by the precious metal platinum. The discovery of platinum’s anticancer properties was made by chance during an experiment in 1965, conducted at Michigan State University by Barnett Rosenberg. Rosenberg used a platinum electrode to apply an electric field to a colony of E. coli, which was observed ...

In this study a simple, highly sensitive, and selective electrochemical method was developed for determination of the low concentration curcumin (CUR) using a poly(vanillin-co-caffeic acid) p(Van-CA) modified platinum electrode. Electrode modification was carried out electrochemically with cyclic voltammetry (CV) method. For this purpose; a solution of 6 mM vanillin (Van) and 6 mM caff...

In this work, platinum group metal (PGM) free-based cathode active layers were prepared using different printing techniques. The membrane electrode assemblies (MEAs) integrate a PGM free catalyst based on Fe, N and C atoms at the side. Scanning electron microscopy (SEM) images of MEA cross sections showed strong impact fabrication process structure, porosity ionomer repartition. MEAs characteri...

This study deals with the manufacturing of catalyst-coated membranes (CCMs) for newcomers in field coating. Although there are many studies on electrode ink composition improving performance proton-exchange membrane fuel cells (PEMFCs), few papers dealing coating itself. Usually, it is a know-how that often remains secret and constitutes added value scientific teams or business industrialists. ...

In this study, the electrochemical mechanism of catechol in presence and absence of nitrite ion, is investigated in phosphate buffer medium (pH=7) using platinum electrode through cyclic voltammetry method in various scan rates. Electrochemical oxidation of catechol showed how quinone has changed to o-benzoquinone and also how o-benzoquinone has reacted with nitrite ion and potential scan rate ...

A method has been developed for the continuous monitoring of oxygen tension in solutions and gases. The oxygen is reduced at a platinum surface which is covered with a plastic membrane. The silver-silver oxide reference electrode is also included under the membrane. Drift is less than 10 per cent for a period of days, and temperature compcnsation is possible. A number of uses to which it has be...

The present dissertation aimed to develop a new microfluidic system for a point-of-care hematocrit device. Stabilization of microfluidic systems via surfactant additives and integration of semipermeable SnakeSkin® membranes was investigated. Both methods stabilized the microfluidic systems by controlling electrolysis bubbles. Surfactant additives, Triton X-100 and SDS stabilized promoted faster...
