Estimation of residual strength of a crack-containing welded pressure vessel exposed to a subzero operating temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
This paper presents a method for estimating the residual-strength of welded pressure vessel made of HSLA steel which contains a surface axial crack. In order to analyze the behavior of the structure, a set of specimens ...
Oxygen reduction reaction on silver electrodes under strong alkaline conditions
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Oxygen reduction reaction (ORR) was studied on a silver polycrystalline electrode in different NaOH concentrations with a help of rotating disc and rotating ring disc electrodes. Soluble reaction intermediate was detected ...
Catalyzing Transcriptomics Research in Cardiovascular Disease: The CardioRNA COST Action CA17129
(MDPI, Basel, 2019)
Cardiovascular disease (CVD) remains the leading cause of death worldwide and, despite continuous advances, better diagnostic and prognostic tools, as well as therapy, are needed. The human transcriptome, which is the set ...
The initial characteristics of the polypyrrole based aqueous rechargeable batteries with supercapattery characteristics
(Elsevier Ltd, 2019)
The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge ...
Impact of plasma treatment on acoustic properties of natural cellulose materials
(Springer, Dordrecht, 2019)
Low-temperature plasma is widely used in many surface treatment technologies for modifications of the physical properties of different polymeric materials. In the present work, we have examined the modification of acoustical ...
Polyphosphate glass as fertilizer for plant seedlings / Efekat primene polifosfatnog stakla u supstratima za gajenje cveća i povrća
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Due to the dissolution properties the phosphate glasses can be promising materials for the development of new ecologically safe fertilizers. The complex polyphosphate glass with a molar ratio (M2O + MO)/P2O5 gt 1 and ...
Solvent influence on absorption spectra of food azo dyes / Uticaj rastvarača na apsorpcione spektre prehrambenih azo boja
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
The solvent influence on absorption spectra of food azo dyes was examined by the method of Linear Solvation Energy Relationships (LSER). For this purpose, six azo dyes were used: tartrazine (E 102), ponceau 4R (E 124), ...
The initial characteristics of the polypyrrole based aqueous rechargeable batteries with supercapattery characteristics
(Elsevier Science Bv, Amsterdam, 2019)
The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge ...
Use of spent brewer's yeast in L-(+) lactic acid fermentation
(Inst Brewing, London, 2019)
The application of by-products from the brewing industry in lactic acid (LA) production was investigated in order to replace expensive nitrogen sources (such as yeast extract) with cheaper and renewable nitrogenous materials ...
Effects of non-thermal atmospheric plasma treatment on dentin wetting and surface free energy for application of universal adhesives
(Springer Verlag, 2019)
The study aims to evaluate the effects of non-thermal atmospheric plasma (NTAP) treatments on dentin wetting and surface free energy (SFE) and compare the effects of NTAP treatment, etch-and-rinse, and self-etch protocols ...
