ABSTRACT. At various calcination temperatures 450, 550 and 650 °C, zinc oxide nanoparticles were produced. Calcinated ZnO has high surface area as the BET was 119.12 m2g–1 average particle radius calculated to be 1.16 nm. The dimension of crystallites straining in nanoparticles' diffraction peaks remained measured. Williamson–Hall (W–H) technique besides size–strain approach stayed used. For ea...

of Vienna, Vienna, Austria; Floridsdorfer Allergiezentrum, Vienna, Austria. Background: Mung beans (Vigna radiata) contain 2 Bet v 1 related proteins: Vig r 1, a member of the PR-10 subfamily, and cytokinin-specific binding protein (CSBP), a protein with low sequence identity (31%) to Bet v 1. We aimed to compare Vig r 1 and CSBP to Bet v 1 regarding biochemical and immunological properties. Me...

Metal organic frameworks (MOFs) are considered an interesting option for hydrogen storage. These materials show an exceptional H2 uptake. Here, Zn3(BTC)2 as MOF was synthesized with a solvothermal method. The phase stability and microstructure of the Zn3(BTC)2 was characterized in terms of their properties and structures, using a number of analytical techniques including FT-IR, XRD, SEM, BET ...

Multi-Walled Carbon Nanotubes (MWCNTs) surfaces were serially modified by the annealing treatment under Helium flow at 1000oC, the nitric acid treatment and again the annealing treatment under same conditions and their maximum adsorption capacities for benzene and toluene were measured and analyzed. The unmodified and modified MWCNTs werecharacterized by Fourier Tr...

In this research, a metal oxide nanocatalyst of ZnO supported copper oxide is reported as a highly efficient recyclable catalyst for the chemoselective synthesis of 1,1-diacetates. The catalyst was synthesized by co-precipitation method and characterized by XRD, BET specific surface area, ESEM, EDS and TEM analysis. A wide range of aldehydes, including aromatic and aliphatic aldehydes were conv...

The activated carbon was prepared from fast precarbonization of reed lignin in the fluidized-bed followed by K2CO3 activation. The impregnation ratio was = 1:1 in this research. The effect of activation temperature upon the BET specific surface area and specific pore volume of the carbon was closely investigated. Increasing activation temperature led to an opening and widening of the porous str...

In this paper we explore the relation between subjective and objective measures of video quality. We computed objective MOS values from video clips using the video quality measuring tool VQM and compared it to the clips’ subjective Acceptability scores. Using the ITU defined mapping (M2G) from MOS to binary Good or Better (GoB) values, we compared the M2G translated values to the clips’ subject...

Pharmaceuticals as an increasing water contaminant pose major hazards to quality and human health. Hydroxyapatite (HAp) has shown promise in the treatment of many contaminants, although it could be improved. The adsorption capacity silver titanium dioxide nanoparticles doped calcined HAp (AgNPs-TiO2NPs@calcined HAp) for acetaminophen (ACT) Ibuprofen (IBP) was investigated this study. Fourier Tr...

Four lignocellulosic materials (walnut shell, chestnut pine wood and burnt wood) were analyzed as biosorbents to remove nickel ions in aqueous solution. The optimal pH condition was determined. Due this, a range of different pHs (3.0 7.5) tested. adsorption isotherms kinetics established. To plot Langmuir Freundlich isotherms, batch tests made with variable concentrations (5 200 mg L−1). pseudo...
