Immobilization of horseradish peroxidase onto kaolin
(Springer, New York, 2016)
Kaolin showed as a very perspective carrier for the enzyme immobilization and it was used for the adsorption of horseradish peroxidase (HRP). The effects of the enzyme concentration and pH on the immobilization efficiency ...
Methacrylic Acid Based Polymer Networks with a High Content of Unfunctionalized Nanosilica: Particle Distribution, Swelling, and Rheological Properties
(Amer Chemical Soc, Washington, 2015)
The poor stability and tendency to agglomerate of unfunctionalized nano-SiO2 in the presence of ionic species presents a challenge for preparing poly(methacrylic acid)/nano-SiO2 nanocomposite (NC) hydrogels with desired ...
Testing of the efficiency of military devices for personal respiratory protection in relation to sub-micron particles of biological agents
(Inst Materials Physics, Bucharest, 2012)
The construction of biological weapons and tactics of its application dictate that dissemination of biological agents on the target has to be in the form of aerosols. The work was done on the effectiveness of filtration ...
Photocatalytic activity of pulsed laser deposited TiO2 thin films in N-2, O-2 and CH4
(Elsevier Science Sa, Lausanne, 2010)
We report on pulsed laser deposition of TiO2 films on glass substrates in oxygen, methane, nitrogen and mixture of oxygen and nitrogen atmosphere. The nitrogen incorporation into TiO2 lattice was successfully achieved, as ...
Antioxidant Protective Effects of Mushroom Metabolites
(Bentham Science Publ Ltd, Sharjah, 2013)
Global industrialization and agricultural development are related to the release of various pollutants into the environment including huge amounts of free radicals, which are associated with the occurrence of various ...
Effect of Deposition Current Density and Annealing Temperature on the Microstructure, Hardness and Magnetic Properties of Nanostructured Nickel-Iron-Tungsten Alloys
(Electrochemical Soc Inc, Pennington, 2014)
Nanostructured nickel-iron-tungsten alloy coatings were electrodeposited from an ammonia citrate bath on steel and copper substrates at current densities in the range of 50 to 300 mA cm(-2). The contents of iron and tungsten ...
Biological activity of electrochemically synthesized silver doped polyvinyl alcohol/graphene composite hydrogel discs for biomedical applications
(Elsevier Sci Ltd, Oxford, 2016)
Silver/poly(vinyl alcohol), Ag/PVA, and silver/poly(vinyl alcohol)/graphene, Ag/PVA/Gr, composite hydrogel discs were produced by freezing/thawing, followed by electrochemical reduction of Ag+ ions inside respective matrices, ...
Raman spectroscopy study of anodic film on Ag43Cu37Zn20 alloy
(Natl Inst Optoelectronics, Bucharest-Magurele, 2016)
The objective of this study was characterization of anodic film obtained when Ag43Cu37Zn20 alloy was treated electrochemically in 3.5% wt. NaCI under potentiostatic conditions. At the potential of +0.25 V a complex multilayer ...
In situ characterization of some sweet and sour cherry autochthonous genotypes in West Serbia region
(Iii International Symposium on Horticultural Crop Wild Relatives, 2019)
Autochthonous cherry genotypes in the Republic of Serbia can potentially provide a rich and useful genetic variability, especially for ripening time, fruit quality and resistance to diseases. Fruit Research Institute, Cacak ...
Lignin degradation by selected fungal species
(Elsevier Sci Ltd, Oxford, 2013)
As biological decomposition of plant biomass represents a popular alternative environmental-friendly and economically justified process, screening of ligninolytic enzyme systems of various fungal species is a topical study ...
