Application of alumosilicate polymers based on metakaolin in adsorption of cadmium ions from wastewater / Primena alumosilikatnih polimera na bazi metakaolina u adsorpciji jona kadmijuma iz otpadnih voda
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Alumosilicate polymers (geopolymers) based on metakaolin as precursor and alkaline activators of different concentrations (2M, 4M, 6M and 8M NaOH/Na2SiO3) were used to remove ions of cadmium from wastewater. Experiments ...
Microvickers hardness determination of unsaturated polyester resins reinforced with alumina based reinforcement / Ispitivanje mikrotvrdoće nezasićenih poliestarskih smola sa ojačanjima na bazi aluminijum oksida
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Commercial alumina wiskers (Al2O3 w) and synthesized alumina particles via sol-gel technique (Al2O3 m) were used as reinforcement in unsaturated polyester resins (UPR). Composite materials with the addition of 0.1 wt. %, ...
The impact of wood fiber surface modification on physical properties of wood-polymer composites / Uticaj modifikacije površine vlakana drveta na mehanička svojstva kompozita polimer-drvo
(Savez inženjera i tehničara Srbije, Beograd, 2016)
In this paper, the impact of wood fiber surface modification on mechanical properties of poly-(methyl methacrylate)(PMMA)-wood composite was examined. FTIR analysis has shown that the wood fiber surface modification was ...
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, ...
Swelling kinetics and impregnation of PLA with thymol under supercritical CO2 conditions / Kinetika bubrenja PLA i njegova impregnacija timolom upotrebom natkritičnog uglenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2016)
The present work was aimed to study swelling kinetics of polylactic acid (PLA) and its impregnation with thymol in supercritical carbon dioxide (scCO2) medium. The influences of temperature and soaking time on the swelling ...
