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 ...
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 ...
Structural and thermal studies of non-metal cation pentaborate salts with cations derived from 1,5-diazobicyclo[4.3.0]non-5-ene, 1,8-diazobicyclo[5.4.0] undec-7-ene and 1,8-bis(dimethylamino)naphthalene
(Elsevier B.V., 2012)
The reaction of the cyclic amines 1,5-diazobicyclo[4.3.0]non-5-ene (DBN), 1,8-diazobicyclo[5.4.0]undec-7-ene (DBU) and 1,8-bis(dimethylamino)naphthalene (PS) with B(OH)3 in a 1:5 ratio affords in high yields the non-metal ...

(Elsevier Ltd, 2016)
A novel two dimensional Metal-Organic Framework (MOF) structured compound with trimesic acid (TMA), 1,10 Phenantroline (Phen) and Cu(II) building blocks were synthesized and characterized experimentally. Then Grand Canonical ...
Preparation and Characterization of PVA/PVP Nanofibers as Promising Materials for Wound Dressing
(2013)
The PVA/PVP, PVA/PVP with 5% and 10% chitosan and PVA/PVP-Iodine fibers were produced via electrospinning technique. Their morphological and chemical characteristics were examined with SEM, TGA, FT-IR, viscometer and ...
Hydrogen storage properties of mono-and bidentate MOF structured orotate complexes
(Materials Research Society, 2014)
One of the barriers for wide usage of hydrogen energy system is efficient storage. To store more hydrogen efficiently, physisorption is a choice among the others with high storage performance, reversibility, and lifecycles. ...
