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, ...
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 ...
Ultrasonic treatment of baker's yeast effluent using SnO2/TiO2 composite
(De Gruyter Open Ltd, 2017)
In this study, ultrasonic treatment of baker's yeast effluent was investigated in an ultrasonic homogenizer emitting waves at 20 kHz. The SnO2/TiO2 composites were used as a sonocatalyst to assist the sonication process. ...
