Insights into the Microwave-Assisted Mild Deconstruction of Lignin Feedstocks Using NiO-Containing ZSM-5 Zeolites
(Amer Chemical Soc, Washington, 2016)
The depolymerization of biolignin (BL), eucalyptus (EL), and hardwood lignins (HL) to simple aromatics was studied by a microwave assisted approach using NiO/H-ZSM-S zeolites as catalysts. The catalysts prepared by the ...
Bactericidal activity of Cu-, Zn-, and Ag-containing zeolites toward Escherichia coli isolates
(Springer Heidelberg, Heidelberg, 2017)
Two types of zeolites-natural clinoptilolite (NZ) and synthetic zeolite A (A)-were enriched with approx. 0.25 mmol of Cu(II), Zn(II), or Ag(I) ions, and the obtained materials (M-Z) were tested against three different ...
Antimicrobial and Photocatalytic Abilities of Ag2CO3 Nano-Rods
(Wiley-VCH Verlag Gmbh, Weinheim, 2017)
The rod-like Ag2CO3 particles (2-4 3 0.3-0.6 mm, length 3 diameter) were synthesized in water by the precipitation reaction between AgNO3 and NaHCO3 in the presence of polyvinylpyrrolidone. The X-ray diffraction analysis ...
Structural, Mechanical and Electrical Characteristics of Copper Coatings Obtained by Various Electrodeposition Processes
(Electronics, 2022)
Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current ...
Covalent immobilization of enzymes on Eupergit® supports: Effect of the immobilization protocol
(Methods in Molecular Biology, 2017)
A selection of best combination of adequate immobilization support and efficient immobilization method is still a key requirement for successful application of immobilized enzymes on an industrial level. Eupergit® supports ...
Evaluation of the impact of critical quality attributes and critical process parameters on quality and stability of parenteral nutrition nanoemulsions
(Elsevier, Amsterdam, 2017)
The aim of this study was to develop, characterize and evaluate concentrated nanoemulsions (20%) for parenteral nutrition. Those systems were developed by the high-pressure homogenization method. Optimal conditions for the ...
Dual responsive antibacterial Ag-poly(N-isopropylacrylamide/itaconic acid) hydrogel nanocomposites synthesized by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Thermo- and pH-sensitive Ag-P(NiPAAm/IA) hydrogel nanocomposites were prepared by in situ reduction of Ag+ ions with gamma irradiation. P(NiPAAm/IA) copolymer hydrogel matrices have been previously synthesized by radiation ...
Traditional and Emerging Technologies for Autochthonous Lactic Acid Bacteria Application
(Springer, New York, 2016)
Autochthonous strains of lactic acid bacteria, isolated from traditional cheeses, may be used as starter cultures in order to standardize the quality of traditional cheeses and/or as potentially beneficial bacteria, allowing ...
Optimization of the electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) colloid solutions
(Bulgarian Acad Science, Sofia, 2017)
This work focuses on the optimization of electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) colloid solutions, films and hydrogel discs with the ability for immobilization of silver nanoparticles and ...
Polyamidoamine as a clay modifier and curing agent in preparation of epoxy nanocomposites
(Elsevier Science Sa, Lausanne, 2019)
In the present study the commercial multifunctional fatty acid polyamidoamine (PAA) was for the first time simultaneously applied as a curing agent and clay modifier for epoxy/clay nanocomposites (NC) based on diglycidyl ...
