‘Plug-and-play’ simplified electrochemical atom transfer radical polymerisation of PEGA480 under potentiostatic and galvanostatic conditions proceeds with very good control to conversions up 83%.

An electrochemical reaction followed by a chemical reaction that recovers the electroactive species in its original form is referred to as electrocatalysis. In aqueous solutions at room temperature the recovering can be achieved with the aid of an enzyme as catalysts which converts substrate S to product P. Figure 1 shows a scheme of such a system for the redox couple OX and RED. This electroch...

The electropolishing behaviour of 73 brass was studied by means of a rotating cylinder electrode (RCE) in a 70 vol % H3PO4 solution at 27 ◦C. Owing to the formation of a blue Cu2+-rich layer on the brass-RCE, an obvious transition peak was detected from kineticto diffusion-controlled dissolution in the anodic polarisation curve. Electropolishing was conducted at the potentials located at the tr...

Potentiodynamic and potentiostatic polarization tests in the potential range between open circuit (OCP) − 0.1 V OCP + 4 were carried out aluminate–phosphate electrolytes with an aluminate concentration of 0.2 mol/L varying phosphates contents 0 mol/L. The pH was adjusted 11.5 12.0 due to phosphate optional KOH addition. A high-strength, dual-phase steel, which is relevant for lightweight constr...

We studied the effects of aeration of Shewanella oneidensis on potentiostatic current production, hydrogen production in a microbial electrolysis cell, and electric power generation in a microbial fuel cell (MFC). The potentiostatic performance of aerated S. oneidensis was considerably enhanced to a maximum current density of 0.45 A/m(2) or 80.3 A/m(3) (mean: 0.34 A/m(2), 57.2 A/m(3)) compared ...

The wide range of properties exhibited by Al based alloy makes them suitable for different applications. Aluminium containing nickel Selenide ternary alloy possess considerable corrosion resistance as compared to their pure metal counterparts. The objective of the present work has been focused on the preparation and characterisation of its thin film. Alloying with Aluminium improve the oxidatio...

We study the photoreduction of adsorbed copper ions onto Au nanoparticles, on an indium tin oxide (ITO) electrode in an aqueous electrochemical cell, as a function of applied voltage and laser intensity. The photocurrent is a nonlinear function of laser intensity and increases sharply with cathodic voltage in the underpotential deposition region. The photoreduction is attributed to laser heatin...

Introduction: The human skin is an active medium from the optical point of view. Therefore, the diagnostic and therapeutic techniques employing light are increasing. Current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. Studies have shown that biological tissues, and in particular skin, demonstrate polarization...
