Synthetic strategies towards the carbenoid reactions of α, β-acetylenic carbonyls
(TÜBİTAK, 2018)
Catalytic reactions of α, β-conjugated carbonyl compounds have been a practical tool towards the synthesis of different useful heterocyclic compounds. Despite the numerous reactions with carbon-carbon double bond conjugated ...
Pore modification in porous ceramic membranes with sol-gel process and determination of gas permeability and selectivity
(2010)
Summary: The aim of the study was to investigate the variation in total surface area, porosity, pore size, Knudsen and surface diffusion coefficients, gas permeability and selectivity before and after the application of ...
Combined experimental and theoretical investigation of characterization and hydrogen storage properties of Zn(II) based complex and composites
(Elsevier Ltd, 2015)
Metal organic structured coordination complex was synthesized by using Zn(II), 1,10 Phenantroline and teraphtalic acid building blocks. Then the synthesized compound have been characterized with Ft-IR, TGA/DTA/DrTGA, EA, ...
Nickel-based bimetallic nanocatalysts in high-extent dehydrogenation of hydrazine borane
(2012)
Hydrazine borane N 2H 4BH 3 (HB) is a promising chemical hydrogen storage material but its development is highly dependent on the catalyst that will be used to dehydrogenate it, that is, to hydrolyze the BH 3 group and ...
The inhibition of steel corrosion in acidic solutions by a new Schiff base
(Sociedad Chilena de Quimica, 2016)
The inhibition effect of 2,2?- (((thiobis (4,1 phenylene)) bis(azanylylidene)) bis(methanylyidene)) bis(4-methoxyphenol) (BIS-IMIN) on the corrosion behavior of 304-stainless steel (SS) in 0.5 M HCl solution was studied ...
