Parametric optimization of the aluminium nanocomposites wear rate
(Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2019)
The optimization of wear rate of the nanocomposites with A356 aluminium alloy matrix, reinforced with silicon carbide nanoparticles, was performed through the analysis of the following influences: wt% of the reinforcement, ...
Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
The influence of gamma irradiation on the color change of wool, linen, silk, and cotton fabrics used in cultural heritage artifacts
(Radiation Physics and Chemistry, 2019)
Fabrics made of wool, linen, silk, and cotton, which are used in the making of artifacts of cultural heritage, were divided into three groups. The first group wasn't dyed, the second group was dyed with natural dye (using ...
Gamma-radiation effects on luminescence properties of Eu 3+ activated LaPO 4 phosphor
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2018)
Eu3+ activated LaPO4 phosphors were prepared by a high-temperature solid-state method and irradiated to different high-doses gamma-radiation in the 0-4 MGy range. No effects of high-doses of high-energy radiation on ...
Composite poly(DL-lactide-co-glycolide)/poly(acrylic acid) hydrogels synthesized using UV and gamma irradiation: comparison of material properties
(Radiation Physics and Chemistry, 2020)
Composite hydrogels capable of controlled drug delivery via ion exchange are an interesting group of materials for the construction of implantable drug reservoirs for electrically charged drugs. In this study, we synthesized ...
DFT study of boron doped MgH2: Bonding mechanism, hydrogen diffusion and desorption
(International Journal of Hydrogen Energy, 2020)
The impact of boron doping on MgH2 bonding mechanism, hydrogen diffusion and desorption was calculated using density functional theory (DFT). Atomic interactions in doped and non-doped system and its influence on hydrogen ...
The corrosion resistance in artificial saliva of titanium and Ti-13Nb-13Zr alloy processed by high pressure torsion
(Procedia Structural Integrity, 2018)
In order to optimize and enhance the implant material properties, metallic materials may be modified by severe plastic deformation (SPD) procedures. One of the most attracting SPD methods is high-pressure torsion (HPT), ...
Synthesis, structural and DFT analysis of a binuclear nickel(II) complex with the 1,4-bis[2-[2-(diphenylphosphino)benzylidene]]phthalazinylhydrazone ligand
(Monatshefte fur Chemie, 2019)
In this work we present the synthesis, and experimental and theoretical analysis of a binuclear nickel(II) complex coordinated to a new phthalazine dihydrazone-based ligand. Single-crystal X-ray diffraction analysis of the ...
Effect of gestational diabetes mellitus and pregnancy-induced hypertension on human umbilical vein smooth muscle KATP channels
(Experimental and Molecular Pathology, 2019)
Gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH) can jeopardize mother and/or fetus. Vascular ATP-sensitive potassium (KATP) channels most likely participate in the processes of diabetes and ...
The influence of the surface nanostructured modification on the corrosion resistance of the ultrafine-grained Ti–13Nb–13Zr alloy in artificial saliva
(Theoretical and Applied Fracture Mechanics, 2019)
On the surface of the ultrafine-grained Ti–13Nb–13Zr alloy and the coarse-grained Ti–13Nb–13Zr alloy nanotubular oxide layers were formed by electrochemical anodization in the 1 M H3PO4 + NaF electrolyte in order to evaluate ...
