Polymer composite films and nanofibers doped with core-shell quantum dots
(Natl Inst Optoelectronics, Bucharest-Magurele, 2020)
Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting ...
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, ...
Valorization of food waste to produce intelligent nanofibrous beta-chitin films
(International Journal of Biological Macromolecules, 2021)
The efficient use of waste from food processing industry is one of the innovative approaches within sustainable development, because it can be transferred into added value products, which could improve economic, energetic ...
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 ...
Leaching of metastannic acid from e-waste by-products
(Springer, New York, 2020)
Anode slime and tin precipitate as by-products of the electrorefining (ER) of non-standard anodes obtained after experimental smelting of waste electric and electronic equipment (e-waste), in addition to the base and ...
Compatibility between TRIZ contradiction matrix and LT-units system / Kompatibilnost između TRIZ matrice kontradiktornosti i LT-sistema
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2020)
The contradiction matrix is the most popular tool of the Theory of Inventive Problem Solving (TIPS, rus. TRIZ). It consists of 39 engineering parameters and 40 principles. Intersecting a parameter that is improving with ...
Validation of a novel perfusion bioreactor system in cancer research
(Savez hemijskih inženjera, Beograd, 2020)
Development of drugs is a complex, time- and cost-consuming process due to the lack of standardized and reliable characterization techniques and models. Traditionally, drug screening is based on in vitro analysis using ...
Resistance to Pit Formation and Pit Growth for Different Tempers of AA2024 Aluminium Alloy in Presence of Benzotriazole
(Korean Inst Metals Materials, Seoul, 2020)
The paper analyses the corrosion behaviour of both naturally and artificially aged AA2024 aluminium alloy in NaCl solution in the presence of the corrosion inhibitor benzotriazole (BTA). The differences between these two ...
Production of sub-micro sized silver particles by chemical reduction method in an environmentally-friendly manner
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Silver nitrate in the solution was reduced in the presence of the dispersants by ascorbic acid, and silver particles were generated. The main goal was to examine the influence of different dispersants. The purpose was to ...
3D Printed Buccal Films for Prolonged-Release of Propranolol Hydrochloride: Development, Characterization and Bioavailability Prediction
(Pharmaceutics, 2021)
Gelatin-polyvinylpyrrolidone (PVP) and gelatin-poly(vinyl alcohol) (PVA) mucoadhesive buccal films loaded with propranolol hydrochloride (PRH) were prepared by semi-solid extrusion 3D printing. The aim of this study was ...
