Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. Because of high amount of water, they are mechanically poor and soft. This aspect limits their applications. The suitability of hydrogels as biomedical materi ...
Although the sunlight mediated inactivation of viruses has been recognized as an important process that controls surface water quality, the mechanisms of virus inactivation by sunlight are not yet clearly understood. We investigated the synergistic role of ...
Neutral and charged assemblies of π-conjugated molecules span the field of organic electronics. Electronic structure computations can provide valuable information regarding the nature of the intermolecular interactions within molecular precursors to organi ...
A series of hydrophilic N,N-dimethylpyrrolidinium-and N,N-dimethylpiperidinium-based ionic liquids (ILs) have been prepared and applied as reaction media in the Wacker oxidation of styrene by hydrogen peroxide using PdCl2 as the catalyst. The efficiency of ...
Two new bis(diphenylphosphino) amines, N,N-bis(diphenylphosphino) benzidine 1 and N, N-bis(diphenylphosphino)- 3,3-dimethoxybenzidine 2 were prepared by aminolysis. Their corresponding oxides, sulfides and selenides were readily prepared by reaction with h ...
Atomistic simulations show that organosilicates, used as low permittivity dielectric materials in advanced integrated circuits, can be made substantially stiffer than amorphous silica, while maintaining a lower mass density The enhanced stiffness is achiev ...
We study hematite (alpha-Fe2O3) photoelectrodes for water splitting by examining the fate of photogenerated holes. Using H2O2 as an efficient hole scavenger, we collect all holes that arrive at the electrode/electrolyte interface. This provides the ability ...
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 ...
The influence of the boron doping level in boron doped diamond electrodes (BDD) on the electro-generation of active intermediates (hydroxyl radicals and hydrogen peroxide) involved in the oxidation of organic compounds has been studied. It is shown that th ...
Tyrosine nitration, often observed during neurodegenerative disorders under nitrative stress, is usually considered to be induced chemically either by nitric oxide and oxygen forming nitrogen dioxide or by the decomposition of peroxynitrite. It can also be ...
