Corrosion behaviour and electrical conductivity of reinforced TiAl3 and B4C hybrid aluminium composites
(Polish Academy of Sciences, 2017)
In this study, corrosion and electric conductivity of aluminum hybrid composites (in situ TiAl3 and ex situ B4C) produced by powder metallurgy are investigated. Hybrid (in situ and ex situ) aluminum composite powders are ...
Effect of surfactant types on the size of tin oxide nanoparticles
(Polish Academy of Sciences, 2017)
In this study, tin oxide (SnO2) nanoparticles were synthesized by hydrothermal method in the presence of hydrazine and ammonia by adding surfactant for 12 h in a Teflon autoclave at 100°C reaction temperature. Tin(II) ...
Preparation and swelling properties of zeolite-poly(2-hydroxyethyl methacrylate-co-acrylic acid) hydrogel composites
(Polish Academy of Sciences, 2016)
Zeolite-Poly(2-hydroxyethyl methacrylate (HEMA)-co-acrylic acid (AA)) hydrogel composite materials were synthesized by in situ free radical addition polymerization technique. The swelling values obtained highly for the ...
Synthesis, characterization and sensing behavior of WO3 nanocrystalline powder for toluene vapor
(Polish Academy of Sciences, 2017)
Tungsten oxide (WO3) nanocrystalline powder was successfully synthesized by direct precipitation technique starting from sodium tungstate dehydrate (Na2WO4•2H2O) as precursor at 80°C for 48 h. The morphological characteristics, ...
Inhibition of ochratoxin A production of aspergillus carbonarius by yeast species
(2011)
A total of 21 yeast strains isolated from wine-grapes of Turkey were screened for their ability to inhibit ochratoxin A (OTA) accumulation by Aspergillus carbonarius in both yeast extract sucrose (YES) broth and grape ...
Production of white barite from barite concentrates of shaking tables by bleaching process after magnetic methods
(Polish Mineral Engineering Society, 2018)
Market price of industrial minerals depends on the purity of products, and increases almost exponentially with the decrease in grade of coloring impurities. Therefore, this work was conducted to investigate the applicability ...
The effect of ball type in fine particles grinding on kinetic breakage parameters
(Polish Mineral Engineering Society, 2015)
In the study, the effect of different grinding media on breakage parameters was investigated. Ceramic and steel balls were used as the grinding media. It was observed that the grinding of ignimbrite obeyed first-order ...
Saturation operation on the direct current motor that is used for manipulator control
(2013)
In this study, the saturation operation on the motor armature current has been carried out with a manipulator control algorithm. Manipulator system is controlled by state feedback plus integral error control strategy. ...
Determination of biogenic amines at low μg L–1levels as acetylacetone derivatives by RP-HPLC with UV-visible detection in expired apple juice samples
(Slovensko Kemijsko Drustvo, 2018)
An accurate and sensitive method for trace quantification of three biogenic amines in expired apple juice samples based on reversed-phase liquid chromatography (RP-HPLC) with UV-visible detection is described. Biogenic ...
