CARBON CRYOGEL AS AN ADSORBENT FOR REMOVAL OF DRUGS AND PESTICIDES FROM WATER
(Society of Physical Chemists of Serbia, 2018)
Carbon cryogel (CC), obtained by pyrolysis of resorcinol–formaldehyde
cryogels, was chemically modified and used for adsorption of drugs and
pesticides from water. FTIR analysis and point of zero charge determination
showed ...
The effect of calcinated hydroxyapatite and magnesium doped hydroxyapatite as fillers on the mechanical properties of a model bisgma/tegdma dental composite initially and after aging
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This study aimed to investigate the possibility of modifying model BisGMA/TEGDMA dental composite by substituting 10 wt. % of conventional glass fillers with bioactive fillers based on calcinated nanosized hydroxyapatite ...
Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
Impregnation of cellulose acetate films with carvacrol using supercritical carbon ioxide / Impregnacija filmova acetata celuloze karvakrolom pomoću natkritičnog ugljenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Cellulose acetate films were impregnated with carvacrol using supercritical carbon dioxide. The supercritical impregnation process, conducted in a static regime at pressure of 21 MPa and temperature of 50°C, was optimized ...
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. %, ...
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. ...
Brewers' spent grain and thin stillage as raw materials in l-(+)-lactic acid fermentation
(Inst Brewing, London, 2018)
Brewer's spent grain (BSG) hydrolysates were used for l-(+)-lactic acid (LA) fermentation by Lactobacillus rhamnosus ATCC 7469. In this study the effect of the addition of various amounts of thin stillage (TS) in BSG ...
Lignin-Degrading Abilities of Novel Autochthonous Fungal Isolates Trametes hirsuta F13 and Stereum gausapatum F28
(Faculty Food Technology Biotechnology, Zagreb, 2018)
The aim of this research is to isolate and identify fungi with high lignin-degrading abilities that are autochthonous to southern Serbian region. Two novel fungal isolates identified as Trametes hirsuta F13 and Stereum ...
Influence of the aerosol flow and exposure time on the structural changes in the filtering half masks material
(Srpsko hemijsko društvo, Beograd, 2018)
The flow of air and aerosol particles through the filtering half masks material depends on the structure porosity. It is very difficult to determine the behaviour of the filtering material during the process of extraction ...
