White-rot fungal pretreatment of wheat straw: effect on enzymatic hydrolysis of carbohydrate polymers
(Institutul de Chimie Macromoleculara Petru Poni, 2023)
The aim of the study was the comparative analysis of degradation of wheat straw lignin by white-rot fungi and its implications on the efficiency of enzymatic hydrolysis of holocellulose. Peroxidases were found to be ...
Oxide Powder Mixture with Poly-vinyl Alcohol (PVA) and added Polyethylene Glycol (PEG) as Plasticizer
(Belgrade : Association for ETRAN Society, 2023)
Powder mixture consisted of ZnO, Mn2O3 (MnCO3) and Fe2O3 blended powders, was found laminating during compaction. Polyvinyl alcohol (PVA) and a combination of PVA with polyethylene glycol (PEG) added as a plasticizer, were ...
Copper(II) and silver(I) complexes with dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz): the influence of the metal ion on the antimicrobial potential of the complex
(Royal Society of Chemistry (RSC), 2023)
Dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz) was used as a ligand for the synthesis of new copper(II) and silver(I) complexes, [CuCl2(py-2pz)]2 (1), [Cu(CF3SO3)(H2O)(py-2pz)2]CF3SO3·2H2O (2), [Ag(py-2pz)2]PF6 ...
Dielectric properties of iPP and aPS nanocomposites with core-shell particles obtained by treatment in transition metal salt solutions
(Wiley, 2023)
The dielectric properties of nanocomposites based on isotactic polypropylene (iPP) and atactic polystyrene (aPS) obtained by novel, simple, and environmentally friendly treatment technique have been analyzed in this study. ...
Correlating Structure and KA2 Catalytic Activity of Zn(II) Hydrazone Complexes

Two new Zn(II) complexes bearing tridentate hydrazone-based ligands with NNO or NNS donor atoms were synthesised and characterised by elemental analysis, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopies, ...
Deterioration Characterization during Thermal Shock Testing
(International Institute for the Science of Sintering (IISS), 2023)
Thermal shock stability plays a great role in the selection of optimal refractory material. Different methods of characterization were developed for this purpose, including the implementation of nondestructive testing. ...
Understanding the Effect of Synthesis and Sintering Temperature on the Functional Properties of Barium Titanate/ Cobalt Ferrite Composites
(Association for ETRAN Society, 2023)
To investigate the effect of synthesis procedure and sintering temperature on the functional properties of perovskite/spinel ceramics, BaTiO3/CoFe2O4 composites were prepared by thermal decomposition, coprecipitation, and ...
The influence of strontium content and sintering temperature on monazite stability
(Association for ETRAN Society, 2023)
This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple ...
