Synthesis, spectral characterisation and thermal behaviours of some new p-tert-butylcalix[4]arene and calix[4]arene-esters containing acryloyl groups
(2013)
The mono-, di-, tri-, and tetra-acryloyl esters of p-tert-butylcalix [4]arene and calix[4]arene were synthesised by reacting acryloyl chloride with sodium salts of p-tert-butylcalix[4]arene and calix[4]arene in THF. The ...
Frequency and voltage dependence of electric and dielectric properties of Au/TiO2/n-4H-SiC (metal-insulator-semiconductor) type Schottky barrier diodes
(Institute of Physics Publishing, 2015)
The main electrical and dielectric properties of Au/TiO2/n-4H-SiC (MIS) type Schottky barrier diodes (SBDs) have been investigated as functions of frequency and applied bias voltage. We believe that the use of high dielectric ...
Synthesis, characterization of poly-2- (2-hydroxybenzylideneamino)-6- phenyl-4,5,6, 7-tetrahydrobenzo[b]thiophene-3-carbonitrile: Investigation of antibacterial activity and optical properties
(2012)
The oxidative polycondensation reaction conditions of 2-(2- hydroxybenzylideneamino)-6-phenyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3- carbonitrile were examined. The magnitude of the reflectance of the polymer decreases ...

Boric acid: A simple molecule of physiologic, therapeutic and prebiotic significance
(Walter de Gruyter GmbH, 2015)
Boric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino- and hydroxy acids, carbohydrates, nucleotides and vitamins ...
CO2 gas detection properties of a TIO2/Al2O3 heterostructure under UV light irradiation
(Institute of Physics Publishing, 2015)
Al/TiO2/p-Si and Al/TIO2/Al2O3/p-Si samples were prepared using the atomic layer deposition method (ALD) and their gas sensing properties were investigated. The electrical properties of the samples were studied using a two ...
Magnetic nanoparticles for plasmid DNA purification through hydrophobic interaction chromatography
(Taylor and Francis Inc., 2014)
Magnetic poly(2-hydroxyethyl methacrylate-co-N-methacryloyl–L-phenyl alanine), p(HEMA-co-MAPA) nanoparticles were produced by emulsion polymerization technique. The nanoparticles were characterized by zetasizer, atomic ...
