Hydrogen peroxide (H2O2) is known to play a multifaceted role in cell physiology mechanisms involving oxidative stress and intracellular signal transduction. Therefore, the development of analytical tools providing information on the dynamics of H2O2 gener ...

The reduction of palladium oxide nanoparticles in the presence of hydrogen peroxide or dissolved oxygen gives rise to a catalytic reduction current dependent on the hydrogen peroxide concentration or the oxygen concentration. Using terephthalic acid as an ...
An amperometric biosensor for adenosine 5 -triphosphate (ATP) was developed applying a competitive assay of two glucose converting enzymes: glucose oxidase (GOD) and hexokinase (HEX). Competition between GOD and HEX for glucose in presence of ATP, lead to ...
In this Article, we studied the surface immobilization of five organic-acid-modified atom-transfer radical polymerization (ATRP) initiators based on salicylic acid, catechol, phthalic acid, and m- and p-benzoic add on alumina, and we also investigated the ...
An oxidative stress (OS) state is characterized by the generation of Reactive Oxygen Species (ROS) in a biological system above its capacity to counterbalance them [1]. Exposure to OS induces the accumulation of intracellular ROS, which in turn causes cell ...
The present PhD thesis deals with the high temperature polymerization of methyl methacrylate in a continuous pilot scale process. The major aim is to investigate the feasibility of a polymerization process for the production of PMMA molding compound at tem ...
CuO powders with a high specific surface area are shown to be able to produce H2O2 in aqueous solution under simulated light irradiation. The highest rate of peroxide production was observed under mild experimental conditions using O2 and a large surface a ...
Several researches have dealt with the thermal initiation of Me methacrylate (MMA) in the past. Some of them already discussed the presence of peroxide contg. species that are formed from dissolved oxygen and the monomer itself as main reason for this init ...
The novel versatile Co(I) tris-carbene complex [(TIMENxyl)Co]Cl (1) (TIMEN = (tris[2-(3-aryl-2,3-dihydro-1H-imidazol-2-ylidene)ethyl]amine)) reacts with CO, 1-electron oxidizers such as CH2Cl2, and O2 to yield the Co complexes [(TIMENxyl)Co(CO)]Cl (2), [(T ...
Escherichia coli (E. coli) photokilling due to the TiO2 under light irradiation in a batch reactor was studied by using of attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and atomic force microscopy (AFM). The ATR-FTIR spectr ...
