The effect of pH on oxygen and hydrogen peroxide reduction on polycrystalline Pt electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Oxygen reduction (ORR) and hydrogen peroxide reduction (HPRR) reactions were studied on polycrystalline Pt by the rotating disc electrode technique in sulphate solutions over the entire pH range. Initial potentials for ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
Ballistic transport through graphene nanostructures of velocity and potential barriers
(Iop Publishing Ltd, Bristol, 2011)
We investigate the electronic properties of graphene nanostructures when the Fermi velocity and the electrostatic potential vary in space. First, we consider the transmission T and conductance G through single and double ...
Synthesis and solution properties of poly(diphenyl itaconate)
(Elsevier, 1976)
Solid diphenyl itaconate monomer was obtained by esterification in the presence of diphosphorus pentoxide and polymerized in bulk with AIBN as initiator. The non-film forming polymer powder was characterized by fractionation, ...
Magnetic field influence on silicon surface periodic structures obtained by plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
External magnetic field influence on silicon submicron surface periodic structures obtained by the action of nitrogen supersonic quasistationary compression plasma flow (CPF) is studied. CPF is generated by magnetoplasma ...
The contributions of high- and low altitude emission sources to the near ground concentrations of air pollutants
(Elsevier Science Inc, New York, 2008)
The scale of transport through the atmosphere depends on the effective height of an emission source, the meteorological conditions and the physico-chemical characteristics of the pollutants. Atmospheric surface temperature ...
dc and ac transport in few-layer black phosphorus
(American Institute of Physics (AIP Publishing), 2020)
The multilayer band structure of black phosphorus (BP) is highly anisotropic, and its bandgap is tunable by applying a perpendicular electric field Ez . Within a linear response theory, we study dc and ac transport in ...
A consideration of the use of metamaterials for sensing applications: Field fluctuations and ultimate performance
(Journal of Optics A: Pure and Applied Optics, 2007)
We analysed some peculiarities of electromagnetic metamaterials convenient for plasmon-based chemical sensing with enhanced sensitivity. Owing to the vastly extended range of possible values of refractive index, a higher ...

Immobilization of glucoamylase via its carbohydrate moiety on macroporous poly(GMA-co-EGDMA)
(Elsevier, 2007)
We succeeded in the immobilization of 190 mg of periodate oxidized glucoamylase per gram of macroporous polymer. The covalently immobilized enzyme had a specific activity of 1100 U/g. The temperature and pH optimum as well ...
