Supercritical co2 impregnation of gelatin-chitosan films with clove essential oil and characterization thereof
(Savez hemijskih inženjera, Beograd, 2019)
Supercritical CO2 impregnation process was used for the first time to fabricate biodegradable gelatin-chitosan (G/Ch) films containing dove oil (CO) for potential use in active food packaging. All the impregnations were ...
Removal of textile dyes from water by TiO2 nanoparticles immobilized on poly(ε-caprolactone) beads and foams
(Serbian Chemical Society, Belgrade, 2018)
This study discusses the possibility of immobilization of colloidal TiO2 nanoparticles (NPs) onto poly(ε-caprolactone) (PCL) beads and foams that could be utilized for the removal of textile dyes from water by photodegradation. ...
Diaquabis(2,2'-dipyridylamine) M(II) Terephthalate Dihydrates, M(II) = Ni, Co: Synthesis, Crystal Structures, Thermal and Magnetic Properties
(Slovensko Kemijsko Drustvo, 2018)
Two new isostructural M(II) (M = Ni, Co) complexes with 2,2'-dipyridylamine (dipya) and dianion of terephthalic acid (H-2 tpht), [M(dipya) (2)(H2O)(2)](tpht) center dot 2H(2)O, have been synthesized by ligand exchange ...
Surface-modified TiO2 powders with phenol derivatives: A comparative DFT and experimental study
(Elsevier, Amsterdam, 2017)
The charge transfer complex formation between TiO2 powder and variety of phenol derivatives (phenol, 4-nitrophenol, 4-bromophenol, 4-tert-butylphenol, hydroquinone) was achieved. The red-shift of optical absorption was ...
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 ...
Modelling, simulation and optimisation of pulse-reverse regime of copper, silver and gold electrodeposition
(Carl Hanser Verlag, 2018)
Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, ...
Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer, New York, 2019)
Secondary alkaline lead slag (SALS), generated during lead-acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Antimicrobial Activity of Thiocarbohydrazones: Experimental Studies and Alignment-Independent 3D QSAR Models
(Wiley-VCH Verlag Gmbh, Weinheim, 2018)
Due to the rise of microbial strains resistant to conventional therapies, there is an urgent need for finding the new antimicrobial chemotypes. Heterocyclic compounds such as thiocarbohydrazones (TCHs) are able to interact ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
The influence of short thermal treatment on structure, morphology and optical properties of Er and Pr doped ceria pigments: Comparative study
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2019)
Potential non-toxic pink and red ceramic pigments based on CeO2 were successfully synthesized by self-propagating room temperature method and thermally treated at 600, 900 and 1200 degrees C for 15 min. The structure, ...
