The influence of Sr and Mn incorporated ions on the properties of microwave single- and two-step sintered biphasic HAP/TCP bioceramics
(Springer, New York, 2014)
The aims of this study were to investigate the effects of Sr- and Mn-doped ions on the sintering behaviors, microstructure and mechanical properties of the bioceramics processed by single- and two-step microwave sintering ...
The Antimicrobial Activities of Silver Nanoparticles Synthesized from Medicinal Mushrooms
(Begell House Inc, Danbury, 2020)
Crude polysaccharide extracts derived from Agaricus bisporus (A), A. brasiliensis (B), and Phellinus linteus (P) were used for the synthesis of silver nanoparticles (AgNPs, labeled AAgNP, BAgNP, PAgNP, respectively) UV and ...
Novel azo pyridone dyes based on dihydropyrimidinone skeleton: Synthesis, DFT study and anticancer activity
(Dyes and Pigments, 2021)
Seven novel azo dyes with 2-pyridone and dihydropyrimidinone moieties have been synthesized and thoroughly characterized. The azo-hydrazone tautomerism has been investigated by experimental and theoretical approaches. The ...
Isopiestic determination of the osmotic and activity coefficients of the {yKBr + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, ...
Recycling of silver-plated brass for production of high purity copper and ultrafine silver powder for electric contacts
(Bulgarian Chemical Communications, 2014)
The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining materials of higher value ...
Antimicrobial activity and biocompatibility of Ag--(+) and Cu2+ -doped biphasic hydroxyapatite/alpha-tricalcium phosphate obtained from hydrothermally synthesized Ag+- and Cu2+ -doped hydroxyapatite
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HAp) powders doped with Ag+ or Cu2+ were synthesized by a hydrothermal method in order to obtain biomaterial with an antimicrobial effect. The synthesis was performed with two contents of dopant (Ag+ or ...
Immobilization of lipase on epoxy-activated Purolite((R)) A109 and its post-immobilization stabilization
(Elsevier Sci Ltd, Oxford, 2014)
In this study, Purolite (R) A109, polystyrenic macroporous resin, was used as immobilization support due to its good mechanical properties and high particle diameter (400 mu m), which enables efficient application in enzyme ...
High Energy/Power Supercapacitor Performances of Intrinsically Ordered Ruthenium Oxide Prepared through Fast Hydrothermal Synthesis
(Wiley-VCH Verlag Gmbh, Weinheim, 2017)
A simple one-step microwave-assisted and temperature-controlled hydrothermal synthesis was applied to prepare a nanocrystalline RuO2 dispersion from an aqueous solution of RuCl3 for supercapacitive applications. The obtained ...
The dependence of the photocatalytic activity of TiO2/carbon nanotubes nanocomposites on the modification of the carbon nanotubes
(Elsevier Sci Ltd, Oxford, 2014)
Nanostructural TiO2/modified multi-wall carbon nanotubes photocatalysts were prepared by hydrolysis of Ti(iso-OC3H7)(4) providing chemical bonding of anatase TiO2 nanoparticles onto oxidized- or amino-functionalized ...
