Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
Antioxidant edible films based on chitosan and starch containing polyphenols from thyme extracts
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to analyse the antioxidant activity of different polymeric matrices based on chitosan and starch, incorporating a thyme extract (TE) rich in polyphenols. TE provided the films with remarkable ...
Synergistic anti-biofouling effect of Ag-exchanged zeolite and D-Tyrosine on PVC composite against the clinical isolate of Acinetobacter baumannii
(Taylor & Francis Ltd, Abingdon, 2014)
Due to their susceptibility to bacterial biofilm formation, commercial tubes for medical use are one of the main sources of hospital infections with Acinetobacter baumannii. The anti-biofouling activity of novel composites ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Influence of common juniper berries pretreatment on the essential oil yield, chemical composition and extraction kinetics of classical and microwave assisted hydrodistillation
(Elsevier Science Bv, Amsterdam, 2018)
The present paper dealt with the influence of the common juniper berries pretreatment on the yield, chemical composition and extraction kinetics of juniper essential oil (JEO) obtained by classical (HD) and microwave ...
The influence of corona treatment and impregnation with colloidal TiO2 nanoparticles on biodegradability of cotton fabric
(Springer, Dordrecht, 2017)
This study discusses the effect of corona pre-treatment at atmospheric pressure and subsequent loading of colloidal TiO2 nanoparticles on the biodegradation behavior of cotton fabric. Biodegradation performance of the ...
Antioxidant activity of PLA/PCL films loaded with thymol and/or carvacrol using scCO2 for active food packaging
(Food Packaging and Shelf Life, 2020)
Present study was aimed to produce biodegradable films with antioxidant activity for active food packaging. Films of poly(lactic acid) (PLA) with 5 wt% of poly(ε-caprolactone) (PCL), denoted as PLA-5, were loaded with ...
Application of whey protein and whey protein hydrolysate as protein based carrier for probiotic starter culture
(Elsevier Sci Ltd, Oxford, 2019)
The main object of study is application of whey protein concentrate (WPC) and whey protein hydrolysate (WPH) for probiotic encapsulation. The controlled enzymatic hydrolysis was applied to change technological properties ...
Enhanced thermo-mechanical properties of acrylic resin reinforced with silanized alumina whiskers
(Elsevier Sci Ltd, Oxford, 2016)
The acrylic resin reinforced with silanized alumina whiskers with self-healing (SH) agents was synthesized. The self-healing system consisted of microcapsules with the healing agent dicyclopentadiene (DCPD) and modified ...
Shape evolution of carbon supported Pt nanoparticles: From synthesis to application
(Elsevier Science Bv, Amsterdam, 2016)
In this research, a water-in-oil microemulsion method with HCl as a capping agent was applied to synthesize carbon supported Pt catalysts. Varying the concentration of HCl caused changes in the shape of obtained nanoparticles, ...
