Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note
(Polymers & Polymer Composites, 2021)
In this study poly (vinyl butyral)/silica (PVB/SiO2) composite films were subjected to the cavitation process. The experiments were carried out with a 10 wt.% PVB solution in ethanol. Silica nanoparticles were added into ...
Solvent effects on structural changes in self-healing epoxy composites
(Elsevier Science Sa, Lausanne, 2020)
Nowadays, there is a very high importance of composite research and variety of their applications in the modern world. In that sense, we researched hollow glass capillaries filled with dissolved Grubbs catalyst (GC) and ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Predicting liquid chromatography−electrospray ionization/mass spectrometry signal from the structure of model compounds and experimental factors; case study of aripiprazole and its impurities
(Elsevier B.V., 2023)
A priori estimation of analyte response is crucial for the efficient development of liquid chromatography–electrospray ionization/mass spectrometry (LC–ESI/MS) methods, but remains a demanding task given the lack of knowledge ...
Experimental and numerical thermo - mechanical analysis of friction stir welding of high - strength alluminium alloy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents experimental and numerical analysis of the change of temperature and force in the vertical direction during the friction stir welding of high-strength aluminium alloy 2024 T3. This procedure confirmed ...

Amino-modified kraft lignin microspheres as a support for enzyme immobilization
(Royal Society of Chemistry, 2020)
In this research, it has been demonstrated that amino-modified microspheres (A-LMS) based on bio-waste derived material, such as kraft lignin, have good prospects in usage as a support for enzyme immobilization, since ...
Composition-property relationship of polyurethane networks based on polycaprolactone diol
(Springer, New York, 2021)
This work was focused on the synthesis of polyurethane networks (PUNs) based on polycaprolactone (PCL) as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation and 4,4 ...
Intermolecular and low-frequency intramolecular Raman scattering study of racemic ibuprofen
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
We report the low-temperature Raman scattering study of racemic ibuprofen. Detailed analysis of the racemic ibuprofen crystal symmetry, related to the vibrational properties of the system, has been presented. The first ...
Comparison of Mechanical Behavior of SiC Sintered Specimen to Analysis of Surface Defects
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Silicon carbide is the material that in sintered form is suiTab. for protection from impact as part of the multilayered structure. Its role is to accumulate energy from the projectile, to plastically deform the projectile ...
