Achieving high antimicrobial activity: Composite alginate hydrogel beads releasing activated charcoal with an immobilized active agent
(Elsevier Sci Ltd, Oxford, 2018)
New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. ...
The impact of high-power ultrasound and microwave on the phenolic acid profile and antioxidant activity of the extract from yellow soybean seeds
(Elsevier Science Bv, Amsterdam, 2018)
The aim of the study was to investigate and compare several extraction protocols like 1) high-power ultrasound probe assisted solvent extraction; 2) microwave assisted solvent extraction; 3) direct acid hydrolysis; 4) ...
Alginate/soy protein system for essential oil encapsulation with intestinal delivery
(Elsevier Sci Ltd, Oxford, 2018)
Preparation of alginate-soy protein isolate (AL/SPI) complex beads containing essential oil of thyme was carried out by emulsification of thyme oil in aqueous sodium alginate solution blended with SPI solution, followed ...
The study of thermal behavior of montmorillonite and hydromica brick clays in predicting tunnel kiln firing curve
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to test montmorillonite and hydromica type of brick clays by using simultaneous thermal analysis and dilatometry in an assessment of the suitability of brick clays to produce building elements. ...
Structural Elucidation of Enzymatically Synthesized Galacto-oligosaccharides Using Ion-Mobility Spectrometry Tandem Mass Spectrometry
(Amer Chemical Soc, Washington, 2016)
Galacto-oligosaccharides (GOS) represent a diverse group of well-characterized prebiotic ingredients derived from lactose in a reaction catalyzed with beta-galactosidases. Enzymatic transgalactosylation results in a mixture ...
Optimization of Al2O3 particle modification and UHMWPE fiber oxidation of EVA based hybrid composites: Compatibility, morphological and mechanical properties
(Elsevier Sci Ltd, Oxford, 2018)
Ultra-high molecular weight polyethylene (UHMWPE, PE)/oxidized PE (ox-PE) fibers and alumina reinforcement were used in preparation of poly (ethylene-co-vinyl acetate) (EVA)/hydrolyzed EVA (EVAOH) based composites. Different ...
Physico-chemical evaluation of hydrophobically modified pectin derivatives: Step toward application
(Elsevier, Amsterdam, 2018)
Present study reports synthesis and physico-chemical evaluation of hydrophobically modified pectin derivatives, obtained by reacting of pectin with di-acyl chlorides (glutaryl and sebacoyl chloride). Depending on length ...
Multifunctional jute fabrics obtained by different chemical modifications
(Springer, 2020)
The aim of the present research is first to reduce the jute fabric non-cellulosic components by using different chemical modifications (i.e. alkali and oxidative) and then to analyze their influence on the jute fabric ...
Towards sustainability of lactic acid and poly-lactic acid polymers production
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Lactic acid (LA) is a platform chemical which can be produced biotechnologically on agricultural residues, wastes and by-products and further used for production of biodegradable, biocompatible LA polymers. These polymers ...
Batch and column adsorption of cations, oxyanions and dyes on a magnetite modified cellulose-based membrane
(Springer, Dordrecht, 2020)
An optimized method is presented to make magnetite (MG) modified cellulose membrane (Cell-MG) from 3-aminopropyltriethoxysilane and diethylenetriaminepentaacetic acid dianhydride functionalized waste cell fibers; (Cell-NH(2)and ...
