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 ...
Processing of hybrid wood plastic composite reinforced with short PET fibers
(Taylor & Francis Inc, Philadelphia, 2018)
Poly(ethylene terephthalate) (PET) fibers (virgin, waste, and mixed) were incorporated in the composite poly(methyl methacrylate) (PMMA)-wood. Hybrid composite panels were prepared by pressure molding. Toluene-2,4-diisocyanate ...
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) ...
Chromatographic and in silico assessment of logP measures for new spirohydantoin derivatives with anticancer activity
(Wiley, Hoboken, 2018)
Lipophilicity has, for a long time, been recognized as a meaningful parameter in structure-activity relationships. It is also the single most informative physicochemical property that reveals a wealth of information on ...
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 ...
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 ...
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. ...
Floating Photocatalyst Based on Poly(epsilon-caprolactone) Foam and TiO2 Nanoparticles for Removal of Textile Dyes
(Korean Fiber Soc, Seoul, 2018)
This study discusses a novel approach for fabrication of floating photocatalyst which can be efficiently exploited for photodegradation of dyes in aqueous solutions. A fabrication of the floating photocatalyst consisted ...
Characterization of scaffolds based on chitosan and collagen with glycosaminoglycans and sodium alginate addition
(Elsevier Sci Ltd, Oxford, 2018)
Scaffolds based on chitosan (CTS), collagen (Coll), and glycosaminoglycans (GAGs) cross-linked by sodium alginate (SA) were obtained with the use of the freeze-drying method. They were characterized by different analyses, ...
