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, ...
A case with IGG4-related retroperitoneal fibrosis-periaortitis rapidly diagnosed and dramatically responded to steroid treatment
(BioMed Central Ltd., 2015)
Retroperitoneal fibrosis is a rare disease characterized by development of fibro-inflammatory tissue, which surrounds and causes compression of the retroperitoneal structures such as abdominal aorta, iliac vessels, vena ...
