Biodegradation of poly(ε-caprolactone) (PCL) and medium chain length polyhydroxyalkanoate (mcl-PHA) using whole cells and cell free protein preparations of Pseudomonas and Streptomyces strains grown on waste cooking oil
(Elsevier Ltd, 2019)
Petrochemical plastics are generally recalcitrant to microbial degradation and accumulate in the environment. Biodegradable polymers obtained synthetically like poly(ε-caprolactone) (PCL) or polyhydroxyalkanoates (PHA), ...
Cavitation resistance of composite polyester resin/basalt powder
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
The paper presents the results of research on cavitation resistance of the composite based on unsaturated polyester resin and basalt powder, as reinforcement. Basalt powder was obtained by grinding and micronising basaltic ...
Recovery of molybdenum oxyanions using macroporous copolymer grafted with diethylenetriamine
(Elsevier, Amsterdam, 2019)
The presented study describes macroporous crosslinked poly(glycidyl methacrylateco-ethylene glycol dimethacrylate) [PGME] functionalized with diethylenetriamine [PGME-deta] as a potential recovery agent for Mo(VI) oxyanions ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
Consolidated vs new advanced treatment methods for the removal of contaminants of emerging concern from urban wastewater
(Elsevier Science Bv, Amsterdam, 2019)
Urban wastewater treatment plants (WWTPs) are among the main anthropogenic sources for the release of contaminants of emerging concern (CECs) into the environment, which can result in toxic and adverse effects on aquatic ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
Characterization of MgAl2O4 Sintered Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Single phase MgAl2O4 was made from a one-to-one molar ratio of MgO and Al2O3 powders mixed using ball-milling. Mixtures of MgO and Al2O3 were subsequently treated in planetary ball mill for 30, 60, 90 and 120 minutes in ...
Compression and strength behaviour of viscose/polypropylene nonwoven fabrics
(Niscair, 2019)
Compression and strength properties of viscose/polypropylene nonwoven fabrics has been studied. Compression behavior of the nonwoven samples (sample compressibility, sample thickness loss & sample compressive resilience) ...
Thermal analysis of polylactic acid under high CO2 pressure applied in supercritical impregnation and foaming process design
(Elsevier Science Bv, Amsterdam, 2019)
Thermal properties of extrusion and injection grade polylactic acid (PLA) were analysed using high pressure differential scanning calorimetry (HP-DSC) under CO2 pressures of up to 50 MPa. The greatest depression of melting ...
Antiosteogenic effect of arsenic trioxide, cholecalciferol, lovastatin or their combination in vitro
(Srpsko hemijsko društvo, Beograd, 2019)
Pathological formation of bone in non-skeletal soft tissues or heterotopic ossification (HO), for which there is currently no effective treatment, is considered to be mediated by activation of Hedgehog (Hh) signaling ...
