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 ...
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. ...
A green approach to starch modification by solvent-free method with betaine hydrochloride
(International Journal of Biological Macromolecules, 2021)
In this study, a novel simple and eco-efficient, semi-dry method with a spray system for starch modification has been developed. Compared to conventional semi-dry methods, this method does not use solvents so that no slurry ...
Volatile compounds of fruits of raspberry 'Meeker' and blackberry 'Cacanska Bestrna' propagated by standard techniques and in vitro micropropagation
(Int Soc Horticultural Science, Leuven 1, 2016)
A two-year research was conducted on volatile compounds of raspberry cultivar 'Meeker' and blackberry cultivar 'Cacanska Bestrna' fruits, harvested at full ripeness and collected from plants propagated by both standard ...
Optimisation of microwave-assisted extraction parameters for antioxidants from waste Achillea millefolium dust
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol ...
In vivo investigation of soft tissue response of novel silver/poly(vinyl alcohol)/ graphene and silver/poly(vinyl alcohol)/chitosan/graphene hydrogels aimed for medical applications - the first experience
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2018)
In this paper, we have shown for the first time the soft tissue response of novel silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) and silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels ...
Electrochemical Synthesis and Characterization of Silver Doped Poly(vinyl alcohol)/Chitosan Hydrogels
(Natl Assoc Corrosion Eng, Houston, 2017)
In this paper, novel silver-doped poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposites were produced by in situ electrochemical synthesis of silver nanoparticles in the polyvinyl alcohol/chitosan/graphene ...
