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 ...
Towards antimicrobial yet bioactive Cu-alginate hydrogels
(IOP Publishing Ltd, Bristol, 2016)
The simplest approach to enhance alginate hydrogel characteristics and functional properties is to replace the calcium in the process of alginate gelation with other metallic ions which are essential for living systems. ...
Novel Approach for Flavonoid Esters Production: Statistically Optimized Enzymatic Synthesis Using Natural Oils and Application in Cosmetics
(Amer Chemical Soc, Washington, 2019)
The present work describes application of natural triglycerides for lipase-catalyzed esterification of structurally diverse flavonoids-esculin, naringin, and phloridzin. Ester mixtures with laurate, linolenate, or linoleate ...
Removal of Anthraquinone Dye by Cross-Linked Enzyme Aggregates From Fresh Horseradish Extract
(Wiley, Hoboken, 2016)
Horseradish roots (Armoracia rusticana) fresh extract was the source of unpurified horseradish peroxidase (HRP) which was used for the immobilization in a form of cross-linked enzyme aggregates (CLEAs). Among three ...
Bioreactor validation and biocompatibility of Ag/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposites
(Elsevier Science Bv, Amsterdam, 2013)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites containing Ag nanoparticles at different concentrations were synthesized using gamma-irradiation. Cytotoxicity of the obtained nanocomposites was determined by MU ...
Highly ordered macroporous gamma-alumina prepared by a modified sol-gel method with a PMMA microsphere template for enhanced Pb2+, Ni2+ and Cd2+ removal
(Elsevier Sci Ltd, Oxford, 2017)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) gamma-alumina was investigated for enhanced Pb2+, Ni2+ and Cd2+ removal. The synthesis was based on a modified sol-gel method using a colloidal ...
Differences in the mode of thermomechanical processing between white gold alloys to produce semi-finished products
(Bulgarian Acad Science, Sofia, 2015)
The results of the investigation of the reduction degree on the hardness of a gold sample with chemical composition Au58,5Ag15Cu9,5Ni9Zn5Pd3 for old white gold alloy and Au58,5Ag18Cu10,5Ga8Zn5 (wt %) for new white gold ...
Application of cellulose acetate for controlled release of thymol
(Elsevier Sci Ltd, Oxford, 2016)
Cellulose acetate (CA) was investigated as a carrier towards development of material with controlled release of thymol as a natural substance with strong antibacterial properties using high pressure techniques. Effect of ...
Potential of Trametes species to degrade lignin
(Elsevier Sci Ltd, Oxford, 2013)
Well developed ligninolytic enzyme system in white-rot mushrooms is responsible for degradation of low degradable and lignin rich unused plant debris, which represents serious environmental ballast. The biological degradation ...
Cyanuric chloride functionalized silica nanoparticles for covalent immobilization of lipase
(Wiley-Blackwell, Hoboken, 2016)
BACKGROUNDIn this work, fumed nano-silica (FNS) was chemically modified to amino (AFNS) and subsequently to cyanuric chloride (CCAFNS) modified silica and tested for the immobilization of lipase from Candida rugosa (CRL). ...
