Customizing the spent coffee for Trichoderma reesei cellulase immobilization by modification with activating agents
(Elsevier Science Bv, Amsterdam, 2018)
This study has explored the possibility to reuse the waste, spent coffee material for the cellulase enzyme immobilization. By the coffee surface modification with different activating agents, it was attempted to develop ...
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 ...
Silver/poly(vinyl alcohol)/chitosan/graphene hydrogels - Synthesis, biological and physicochemical properties and silver release kinetics
(Elsevier Sci Ltd, Oxford, 2018)
This study presents the synthesis of novel silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels by in situ electrochemical reduction of silver ions in the hydrogel matrix and their thorough ...
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) ...
Mesoporous Silica and Organosilica Nanomaterials as UV-Blocking Agents
(Amer Chemical Soc, Washington, 2018)
Mesoporous silica nanoparticles (MSN) and periodic mesoporous organosilica nanoparticles containing bridging benzene (PMOBTB) and ethane (PMOBTE) moieties are synthesized, characterized, and evaluated for application in ...
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 ...
Continuous biodiesel production under subcritical condition of methanol - Design of pilot plant and packed bed reactor with MnCO3/Na-silicate catalyst
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
The continuous biodiesel production from soybean oil was carried out under the subcritical condition of methanol with MnCO3/Na-silicate as a heterogeneous catalyst. The transesterification rate was first investigated in a ...
Structural design of face fabrics and the core as a premise for compression behavior of 3D woven sandwich fabric
(Sage Publications Ltd, London, 2018)
In this work, an experimental study on compression properties of two E-glass 3D woven fabrics, known as integrally woven sandwich fabrics, has been presented. Compression properties of 2D face fabrics and the core, as ...
Response surface methodology for optimisation of edible coatings based on dextran from Leuconostoc mesenteroides T3
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this study was to develop dextran-based edible films plasticized by sorbitol. In order to optimise the film-forming formulation, response surface methodology was used. The influence of dextran and sorbitol ...
