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) ...
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 ...
A Computational Model for Drug Release from PLGA Implant
(MDPI, Basel, 2018)
Due to the relative ease of producing nanofibers with a core-shell structure, emulsion electrospinning has been investigated intensively in making nanofibrous drug delivery systems for controlled and sustained release. ...
Sorption of textile dyes from textile wastewater by chitosan-based hydrogel / Sorpcija boja za tekstil iz tekstilnih otpadnih voda pomoću hidrogela na bazi hitozana
(Savez inženjera i tehničara Srbije, Beograd, 2018)
With the excessive risks that are present in today's environment, it is of great importance to treat wastewaters before their discharge in water streams. One of the everyday challenges is design of a low-cost and environmentally ...
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 ...
Synthesis and properties of nano-hydroxyapatite/poly (methacrylic acid) composite hydrogels / Uticaj neutralizacije na svojstva poroznih hidrogelova na bazi hidroksiapatita i poli(metakrilne kiseline) sintetisanih slobodno-radikalskom polimerizacijom
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Goals. The goal of this study was a development of biocompatible composite hydrogels, structurally similar to native bone tissue, by incorporation of ~60 wt % of calcium hydroxyapatite (HA) into a matrix of hydrogels. Also, ...
Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
