Safe-by-design gelatin-modified zinc oxide nanoparticles
(Journal of Nanoparticle Research, 2021)
We report an innovative low-cost wet precipitation synthesis method for gelatin-modified zinc oxide nanoparticles (GM ZnO NPs) at the interface between the gelatin hydrogel and aqueous electrolyte. Diffusion of ammonia ...
Hydrochemical changes and groundwater grouping data by multivariate statistical methods within one karst system: recharge-discharge zone (Eastern Serbia case study)
(Springer, New York, 2020)
To define changes in hydrochemical composition from the recharge to the discharge zone of the complex Kucaj-Beljanica karst massif, located in eastern Serbia, on a quarterly basis within one hydrologic year, a physico-chemical ...
Complementary methods for characterization of the corrosion products on the surface of Ag60Cu26Zn14 and Ag58.5Cu31.5Pd10 brazing alloys
(Walter de Gruyter Gmbh, Berlin, 2020)
Corrosion products formed on the surface of two silver brazing alloys after the potentiostatic polarization in 3.5% sodium chloride solution were characterized by the standard methods such as, the X-ray diffraction, ...
Effect of composition and method of preparation of 2-hydroxyethyl methacrylate/gelatin hydrogels on biological in vitro (cell line) and in vivo (zebrafish) properties
(Springer, Dordrecht, 2020)
We have studied the effect of compositions and methods of preparation on the physico-chemical and biocompatible behavior of the hydrogel matrices. Hydrogel matrices are synthesized by free radical polymerization of ...
Composition, structure and potential energy application of nitrogen doped carbon cryogels
(Materials Chemistry and Physics, 2020)
Resorcinol–formaldehyde (RF) cryogels were synthesized by sol–gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Preparation of floating polymer-valsartan delivery systems using supercritical CO2
(Journal of Polymer Research, 2021)
This study investigates pharmaceutical polymers (Soluplus((R)), HPMCAS, and Eudragit((R)) E100) and supercritical CO2-assisted process for preparation of floating valsartan delivery systems. Tested process (at pressure of ...
Enzymatically derived oil-based L-ascorbyl esters: Synthesis, antioxidant properties and controlled release from cosmetic formulations
(Elsevier B.V., 2020)
Lipase-catalyzed transesterification of vitamin C by natural triglycerides is promising approach for cost-efficient synthesis of liposoluble food and cosmetic antioxidants. Nevertheless, application of these alternative ...
Multi-criteria ranking of organizational factors affecting the learning quality outcomes in elementary education in Serbia
(Journal of Business Economics and Management, 2021)
The research within this paper is motivated by the opinion that different organizational factors in primary education can have a stronger or weaker impact on the quality of the learning outcome. Organizational factors, ...
Fast Oxide-Ion Conductors in Bi2O3-V2O5 System: Bi108-xVxO162+x(x=4-9) with 3 x 3 x 3 Superstructure
(Science of Sintering, 2021)
In this study, the possibility to stabilize O-2 ion conductors in Bi2O3-V2O5 system was investigated. Six pseudo-binary Bi2O3-V2O5 mixtures [3.50 lt x(V2O5) lt 8.50 mol%] were thermally treated at 1000 degrees C for 1 ...
Amino-modified hollow alumina spheres: effective adsorbent for Cd2+, Pb2+, As(V), and diclofenac removal
(Environmental Science and Pollution Research, 2021)
A simple sol-gel method and external gelatinization method of hollow alumina spheres synthesis were developed in this study. The spheres were modified with polyethyleneimine (PEI) producing PEI-Al2O3 via (3-glycidyloxypr ...
