Investigation of interface and surface energy states in semiconductors by PA method
(European Physical Journal: Special Topics, 2008)
The photoacoustic (PA) signal should generally change with the extent of damage, in the form of surface energy states (SES) or interface energy states (IES). For a mechanically, chemically or particles processed (Ar-plasma ...
Degradation of transformer oil on the basis of polychlorinated bifenyls without degrading the existing quality of the environment / Degradacija transformatorskog ulja na bazi polihlorovanih bifenila bez narušavanja postojećeg kvaliteta životne sredine
(Elektroprivreda, 2003)
This paper deals with results of laboratory experiments referring to transformer oil chemical degradation on the basis of polychlorinated bifenyls, results referring to rinsing of transformer insulation material, as well ...
The roughness analysis of metal coatings by STM technique part III: Analysis of copper coatings electrodeposited with thiourea as brightening additive / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije III deo - analiza prevlaka bakra istaloženih sa tioureom kao aditivom za sjaj
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)

Structural and electrochemical properties of nesting and core/shell pt/tio2 spherical particles synthesized by ultrasonic spray pyrolysis
(MDPI, 2020)
Pt/TiO2 composites were synthesized by single-step ultrasonic spray pyrolysis (USP) at different temperatures. In an in-situ method, Pt and TiO2 particles were generated from tetra-n-butyl orthotitanate and chloroplatinic ...
Solid state and solution structures of Cd(II) complexes with two N-heteroaromatic Schiff bases containing ester groups
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Two novel cadmium(II) complexes with condensation derivatives of 2-acetylpyridine or 2,6-diacetylpyridine with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures of the complexes revealed a ...
Ab initio and density functional study of barrier heights for methyl group torsion and conformational deformability in 1,4,6-trimethylnaphthalene
(Elsevier, 2012)
The results of an investigation into barrier heights for methyl group torsion in the ground electronic state of 1,4,6-trimethylnaphthalene (TMN) is presented. Different approaches (HF, MP2, B3LYP, CCSD(T)) have been employed ...
Degradation of anionic surfactants using the reactor based on dielectric barrier discharge
(Serbian Chemical Soc, Belgrade, 2016)
Two anionic surfactants (sodium lauryl sulfate - SDS and sodium dodecylbenzenesulfonate - SDBS) were treated with dielectric barrier discharge. Loss of surfactant activity, decrease in chemical oxygen demand (COD) and total ...
Surface modification of polyethylene by Ag+ and Au+ ion implantation observed by phase imaging atomic force microscopy
(Elsevier, 2012)
High density polyethylene (HDPE) has been modified by Ag+ and Au+ ion implantation with the energy of 60 and 200 keV, respectively. The doses of implanted silver and gold ions were as follows: 1 x 10(15), 5 x 10(15) and 1 ...
Introduction of Pt and Pd Nanoclusters in Zeolite Cavities by Thermal Degradation of Acetylacetonates
(Trans Tech Publications, Switzerland, 2004)
Nanodispersed metallic clusters of platinum and palladium were incorporated into NaX
zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates, solvent
evaporation and acetylacetonate ...
Frequency response analysis as a tool for fast evaluation of periodic operations. Case study: A heterogeneous catalytic reacator
(2nd European Process Intensification Conference (EPIC 2009), Venice, Italy, 2009)
One way to achieve process intensification is to operate the process in a periodic way, in
order to obtain better average performance compared to the optimal steady-state operation.
The source of the possible improvement ...
