Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
Stability of Metal-Oxide Varistor Characteristics in Exploitation Conditions
(Acta Physica Polonica A, 2009)
Wide-spread use of metal-oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various ...
Identification of phases formed by Cu and Ni in Al-Si piston alloys
(Associazione Italiana di Metallurgia, 2014)
This paper presents the results of identifying and analyzing the phases present in the microstructure of 4 aluminum piston alloys with different chemical composition. Optical microscopy and scanning electron microscopy ...
Phenomenology of a formation of a honeycomb-like structure during copper electrodeposition
(Journal of Solid State Electrochemistry, 2007)
In this paper, the phenomenology of a formation of a honeycomb-like structure was considered. Copper deposits obtained at overpotential of 1000 mV were examined by scanning electron microscopy (SEM) technique. It was shown ...
Leaching of metastannic acid from e-waste by-products
(Springer, New York, 2020)
Anode slime and tin precipitate as by-products of the electrorefining (ER) of non-standard anodes obtained after experimental smelting of waste electric and electronic equipment (e-waste), in addition to the base and ...
Influence of gamma radiation on measurement fast pulse voltages by Kerr electro-optic effect
(Radiation Effects and Defects in Solids, 2021)
In this paper, the possibility of measuring the electronic pulse from an electronic generator for plasma heating by electro-optical method is considered. The experiments are performed by applying the Kerr effect on an ...
Viscoelasticity of multicellular systems caused by collective cell migration: dynamics at the biointerface
(Springer, New York, 2020)
Viscoelasticity of multicellular systems caused by collective cell migration depends on (1) viscoelasticity of migrating clusters, (2) viscoelasticity of surrounding resting cells and (3) the size, slip effects and thickness ...
Polymer composite films and nanofibers doped with core-shell quantum dots
(Natl Inst Optoelectronics, Bucharest-Magurele, 2020)
Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting ...
Adsorption performances and antimicrobial activity of the nanosilver modified montmorillonite clay
(Desalination Publ, Hopkinton, 2020)
The synthesis and adsorption potential of Cy-npAg, obtained by modification of raw montmorillonite clay (raw-Cy) with silver nanoparticle (npAg), was studied in this work. Optimization procedure, with respect to time, ...
Structural and surface modification of highly ordered alumina for enhanced removal of Pb2+, Cd2+ and Ni2+ from aqueous solution
(Desalination Publ, Hopkinton, 2020)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) alumina doped with iron oxide, and subsequently modified with (3-aminopropyl)triethoxysilane (APTES), FeAl2O3 and FeAl(2)O(3)APTES, was used for ...
