Opportunities, perspectives and limits in lactic acid production from waste and industrial by-products
(Savez hemijskih inženjera, Beograd, 2016)
In line with the goals of sustainable development and environmental protection today great attention is directed towards new technologies for waste and industrial by-products utilization. Waste products represent potentially ...
Influence of surface modification to mechanical and thermal properties of nanomodified acrylic dental resin
(Inst Materials Physics, Bucharest, 2018)
This paper investigated the processing and characterization of dental nanocomposites based on poly(methyl methacrylate) (PMMA) matrix reinforced with zirconium dioxide (ZrO2) nanoparticles were prepared by in-situ free ...
In vivo investigation of soft tissue response of novel silver/poly(vinyl alcohol)/ graphene and silver/poly(vinyl alcohol)/chitosan/graphene hydrogels aimed for medical applications - the first experience
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2018)
In this paper, we have shown for the first time the soft tissue response of novel silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) and silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels ...
Influence of the aerosol flow and exposure time on the structural changes in the filtering half masks material
(Srpsko hemijsko društvo, Beograd, 2018)
The flow of air and aerosol particles through the filtering half masks material depends on the structure porosity. It is very difficult to determine the behaviour of the filtering material during the process of extraction ...
In vitro conservation of cherry rootstock Gisela 5
(Natl Inst Science Communication-Niscair, New Delhi, 2015)
The paper presents results of the application of 'Cold Storage' (CS), a very simple in vitro technique preservation of cultures at +5 degrees C in total darkness. A protocol has been developed for in vitro preservation of ...
Development and validation of a stability-indicating LC-UV and LC-MS/MS methods for quantitative analysis of anisomycin and identification of degradation products
(University of Sao Paulo, Conjunto Quimicas, Sao Paulo, 2018)
Multifunctional drug anisomycin was subjected to forced degradation in accordance with International Conference on Harmonisation (ICH) guidelines for the first time. The drug was exposed to the recommended stress conditions ...
Removal of emerging pathogenic bacteria using metal-exchanged natural zeolite bead filter
(Iwa Publishing, London, 2019)
Hospital wastewaters can become a route for dissemination of antibiotic-resistant bacteria to the environment if not properly treated. Some of these bacteria are able to survive conventional disinfection treatments (e.g. ...
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 ...
Thermodynamics of mixed and pure aqueous solutions of K2HPO4 at T=298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Experimental results on isopiestic measurements for three ternary aqueous solutions of K2HPO4 with KCl, KBr, and KNO3 at T = 298.15 K were modeled with the Clegg-Pitzer-Brimblecombe equation based on mole-fraction-composition ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
