Microstructure, roughness, and corrosion resistance of X5CrNi18-10 austenite stainless steel welded joint / X Mikrostruktura , hrapavost i otpornost na koroziju zavarenog spoja austenitnog nerđajućeg čelika X5CrNi18-10
(Belgrade : Serbian Chemical Society, 2021)
The influence of the microstructure of X5CrNi18-10 stainless steel welded joint on its resistance to general, pitting, and intergranular corrosion was analyzed. The structure of weld metal, heat affected zone (HAZ) and ...
Frequency-response-controlled multiple-resonator-based harmonic analysis
(Hertford : The Institution of Engineering and Technology, 2018)
This Letter proposes a modified method for the dynamic harmonic analysis of signals with non-stationary harmonics, which is based on the previously proposed multiple-resonator observer structure. An optimisation technique ...
The initiation of dendritic growth of electrodeposited copper on a rotating disc electrode with changing copper concentration and diffusion layer thickness
(Elsevier, 1992)
It is shown that the critical overpotential of dendritic growth initiation increases with increasing copper concentration under identical hydrodynamic conditions, as well as with increasing rotation speed to the rde (rotating ...
IR and UV/VIS Spectroscopic Characterization of the Higher Fullerene C-76-D-2 for Its Quantitative and Qualitative Determination
(Hindawi Limited, 2018)
The only stable isomer of the higher fullerene C-76 of D-2 symmetry was isolated from carbon soot by the new and advanced extraction and chromatographic methods and processes. Characterization of the isolated C-76-D-2 was ...
Efficient stabilization of Saccharomyces cerevisiae external invertase by immobilisation on modified beidellite nanoclays
(Elsevier Sci Ltd, Oxford, 2015)
The external invertase isoform 1 (EINV1) was immobilised on eight differently modified beidellite nanoclays, Modifications were composed of organo-modification with different amounts of surfactant - hexadecyl trimethylammonium ...
Macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) resins-Versatile immobilization supports for biocatalysts
(Elsevier, 2009)
Crosslinked macroporous hydrophilic poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)s [abbreviated poly(GMA-co-EGDMA)] with identical chemical structure (60% of glycidyl methacrylate) but with varied average ...
Structural effects in electrocatalysis: oxidation of formic acid and hydrogen adsorption on platinum single-crystal stepped surfaces
(Elsevier, 1986)
The oxidation of formic acid and hydrogen adsorption have been measured on platinum single-crystal stepped surfaces with five orientations. A pronounced structural sensitivity of both reactions has been found. They show a ...
Bioactive Compounds in Wild, In vitro Obtained, Ex vitro Adapted, and Acclimated Plants of Centaurea davidovii (Asteraceae)
(Natural Products Inc, Westerville, 2015)
In vitro cultures were initiated from a single seed of Centaurea davidovii. Whole plantlets were regenerated and cultivated for several months on agar-solidified nutrient media differing by their composition: basal MS ...
Methanol oxidation on Pd/Pt(poly) in alkaline solution
(Elsevier, 2015)
Bimetallic electrodes prepared by Pd nanoislands spontaneously deposited on polycrystalline platinum, Pt(poly), at submonolayer coverage were explored for methanol oxidation in alkaline media. Characterization of obtained ...
Antioxidant Capacity and Quality of Human Milk and Infant Formula Determined by Direct Current Polarography
(Springer, 2021)
Antioxidants present in infant food contribute to its nutritive value and provide protection from oxidative damage. Here, a direct current polarographic method, based on a decrease of anodic current from the hydroxoperhy ...
