Porous carbon thin films for electrochemical capacitors
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Activation effects on carbon films, derived from commercial aromatic polyimide films (Kapton, DuPont), in CO2 atmosphere at 1203 K on capacitance properties were studied. Two thicknesses of polyimide films were used: 7 and ...
Engineered surface waves in hyperbolic metamaterials
(Optical Society of America, 2013)
We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO center dot ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Superior capacitive and electrocatalytic properties of carbonized nanostructured polyaniline upon a low-temperature hydrothermal treatment
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Carbonized nanostructured polyaniline (C.PANI) was hydrothermally treated in 1 mol dm(-3) KOH at 200 degrees C. The treatment caused significant reduction of micropore volume but negligible changes in mesoporous domain, ...
Arylpiperazine-mediated activation of Akt protects SH-SY5Y neuroblastoma cells from 6-hydroxydopamine-induced apoptotic and autophagic death
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
We investigated the ability of 19 recently synthesized arylpiperazine compounds to protect human SH-SY5Y neuroblastoma cells from the neurotoxin 6-hydroxydopamine (6-OHDA). The compound with the most potent neuroprotective ...
Analysis of the competitive adsorption and mass transfer influence on equilibrium mass fluctuations in affinity-based biosensors
(Elsevier, 2013)
We analyze the fluctuations of the equilibrium adsorbed mass in affinity-based biosensors, considering adsorption-desorption and mass transfer processes of two molecular species which compete for binding to the same probe ...
Extensive feedwater quality control and monitoring concept for preventing chemistry-related failures of boiler tubes in a subcritical thermal power plant
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Prevention and minimizing corrosion processes on steam generating equipment is highly important in the thermal power industry. The maintenance of feedwater quality at a level corresponding to the standards of technological ...
Composition, antifungal and antioxidant properties of Hyssopus officinalis L. subsp pilifer (Pant.) Murb. essential oil and deodorized extracts
(Elsevier, 2013)
The aim of the study was to investigate the chemical composition of Hyssopus officinalis L subsp. pilifer (Pant.) Murb. essential oil (EO) and deodorized extracts (DE) and to evaluate their potential antifungal and antioxidant ...
Improving dispersion of SnO2 nanoparticles in Ag-SnO2 electrical contact materials using template method
(Elsevier, 2013)
Considering that improvement in the performance of Ag-SnO2 electrical contact materials can be realized by an increase in metal oxide dispersion, the influence of SnO2 nanoparticles and method of their introduction in ...
