Oxidation of hydroxide ions at platinum-modified zeolite electrode / Izvod oksidacija hidroksilnih jona na zeolitu modifikovanom platinom
(Association of Chemical Engineers of Serbia, 2012)
NaX zeolite was modified by platinum via impregnation/thermal decomposition technique, using Pt(II)-acetyl acetonate in acetone as an impregnating solution. The samples were characterized by scanning electron microscopy ...
Field applicable methods for intergranular corrosion testing of stainless steels structures / Metode ispitivanja interkristalne korozije na konstrukcijama od nerđajućh čelika na terenu
(Society for Structural Integrity and Life, 2016)
Determination of the susceptibility of austenitic stainless steel X5CrNi18-10 to intergranular corrosion (IGC) is performed by measuring the corrosion potential Ecorr in a drop of a test solution with specific chemical ...
The importance of Lean concept in sustainable development of enterprises with small scale production
(Belgrade, Serbia : United Association of Serbia for Quality (UASQ), 2016)
This paper presents an algorithm that makes it possible to improve manufacturing process in an enterprise with small scale production. Today, Lean concept is more and more used in the process ...
Heteropentanuclear Oxalato-Bridged nd-4f (n=4, 5) Metal Complexes with NO Ligand: Synthesis, Crystal Structures, Aqueous Stability and Antiproliferative Activity
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
A series of heteropentanuclear oxalate-bridged Ru(NO)-Ln (4d-4f) metal complexes of the general formula (nBu(4)N)(5)[Ln{RuCl3(-ox)(NO)}(4)], where Ln=Y (2), Gd (3), Tb (4), Dy (5) and ox=oxalate anion, were obtained by ...
Real-Time AFM and Impedance Corrosion Monitoring of Environmentally Friendly Ceria Films on AA7075
(The Electrochemical Society, 2020)
Cerium-based conversion coatings have emerged as promising green alternatives to the harmful chromium-based ones, but the mechanism of corrosive protection still remains a subject of academic and industrial research. This ...
Fractal analysis of bentonite modified with heteropoly acid using nitrogen sorption and mercury intrusion porosimetry / Fraktalna analiza bentonita modifikovanog heteropoli kiselinom korišćenjem podataka sorpcione analize i živine porozimetrije
(Serbian Chemical Society, 2011)
Experimental adsorption isotherms were used to evaluate the specific surface area and the surface fractal dimensions of acid-activated bentonite samples modified with a heteropoly acid (HPW). The aim of the investigations ...
Two-dimensional gradient-index metamaterial with sawtooth profile
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2013)
We investigate theoretically and experimentally a binary metal-dielectric metamaterial with a sawtooth profile. The structure consists of a two-dimensional array of pillars with submicrometer diameters. The pillar diameters ...
Photochemical activation of air pollutants, related to the preservation of cultural heritage / Fotohemijska aktivacija zagađivača vazduha i veza sa očuvanjem kulturnog nasleđa
(Sarajevo : University of East Sarajevo, Faculty of Technology, 2011)
It is well known that the exposition to air and weather markedly enhances derogation of
all artifacts. In this report, the contribution of light (particularly sunlight) to marked speed-up
of the oxidation and other changes ...
