Solvent effects on pKa values of some substituted sulfonamides in acetonitrile-water binary mixtures by the UV-spectroscopy method
(2009)
The examination of the dissociation constants of sulfonamides is essential in drug-design studies and in explaining the biopharmaceutical properties of substances. The dissociation constants of ten common human and veterinary ...
Comparison of the curing kinetic behavior for two epoxy resin systems containing EPIKOTE 828-EPIKURE 3090 and DURATEK KLM 606a-DURATEK KLM 606b
(2007)
The aim of the study is to determine the optimum cure temperatures and kinetics for two different epoxy resin systems without using solvent. Two resin systems consist of EPIKOTE 828® epoxy resin-EPIKURE® 3090 polyamidoamine ...
Processing of urea-formaldehyde-based particleboard from hazelnut shell and improvement of its fire and water resistance
(Wiley Blackwell, 2009)
The purpose of this study was to manufacture urea-formaldehyde-based particleboard from hazelnut shell and eliminate its disadvantages such as flammability, water absorption, swelling thickness by using fly ash and ...
Residual stress analysis snd expansion of plastic zone in simple supported and clamped supported woven Ni-Cr reinforced thermoplastic matrix composite laminated plates
(2007)
In this study, a residual stress analysis is carried out on symmetric cross-ply and angle-ply thermoplastic simple supported and clamped supported laminated plates for transverse loading. Low density polyethylene thermoplastic ...
An elastic-plastic stress analysis of woven Ni-Cr reinforced thermoplastic composite cantilever beam
(2007)
In the present study an analytical elastic-plastic stress analysis is carried out for a low-density homogeneous polyethylene thermoplastic cantilever beam reinforced by Ni-Cr steel fibers. The beam is loaded by a constant ...
