Insight in the regioselective enzymatic transgalactosylation of salicin catalyzed by beta-galactosidase from Aspergillus oryzae
(Elsevier Sci Ltd, Oxford, 2015)
In this study, enzymatic synthesis of galactoside of salicin, compound with potential physiological activity due to structural resemblance with galectin inhibitors, and analgesic and antipyretic properties of salicin, was ...
Study on the formation of an amoxicillin adduct with methanol using electrospray ion trap tandem mass spectrometry
(Wiley, Hoboken, 2008)
The possibility of using the protonated methanol-adduct of antimicrobial amoxicillin for its identification and quantification at residue levels has been investigated, since it is impossible to completely suppress the ...
Poly(acrylamide-co-itaconic acid) and semi-IPNS with poly(ethylene glycol): Preparation and characterization
(Wiley-VCH Verlag Gmbh, Weinheim, 2004)
A pH-responsive poly(acrylamide-co-itaconic acid) (PAAm/IA) hydrogel and semi-interpenetrating networks (semi-IPNs) with 5, 10 and 15 wt.-% of poly(ethylene glycol) (PAAm/IA/PEG), were synthesized. Their swelling behavior ...
Analysis of the composite and film hardness of electrodeposited nickel coatings on different substrates
(Elsevier Science Sa, Lausanne, 2008)
Fine-grained nickel thin films were electrodeposited from a self-made sulphamate-based electrolyte on different substrates: polycrystalline cold-rolled copper and single crystal silicon with two different orientations, ...
Phase-transformation kinetics in triphasic cordierite gel
(Cambridge Univ Press, New York, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
Life Cycle Energy Assessment of biohydrogen production via biogas steam reforming: Case study of biogas plant on a farm in Serbia
(International Journal of Hydrogen Energy, 2021)
The aim of this paper is to demonstrate and to quantify energy flows in a life cycle of biogas to biohydrogen production, starting from feedstock materials via anaerobic digestion, biogas upgrading, biohydrogen production, ...
In situ radical polymerization of methyl methacrylate in a solution of surface modified TiO2 and nanoparticles
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Surface modified TiO2 nanoparticles dissolved in toluene were encapsulated in PMMA by in situ radical polymerization of methyl methacrylate initiated by 2,2'-azobisisobutyronitrile. The surface modification of the TiO2 ...
Antimicrobial activity of metal oxide nanoparticles supported onto natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The antimicrobial activity of Cu2O, ZnO and NiO nanoparticles supported onto natural clinoptilolite was investigated in the secondary effluent under dark conditions. After 24 h of contact the Cu2O and ZnO nanoparticles ...
A kinetic study of the release of vanillin encapsulated in Carnauba wax microcapsules
(Elsevier Sci Ltd, Oxford, 2012)
Thermal release of vanillin encapsulated in Carnauba wax microcapsules was studied by isothermal thermogravimetric analysis at 443, 453, 473, and 483 K. The thermal analysis data were analyzed kinetically and it was found ...
The problems in design and detailed analyses of energy consumption for biodiesel synthesis at supercritical conditions
(Elsevier, Amsterdam, 2009)
The main goal of this study is analysis the existing and recently published data related to design of larger scale plant for biodiesel synthesis at supercritical conditions. Such analysis was focused on the problem of ...
