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 ... -
The effect of aluminum and ammonium perchlorate content on temperature sensitivity, mechanical properties and performance of HTPB propellants
(The Japan Society for Aeronautical and Space Sciences, 2007)This paper describes the effect of aluminum content variation of HTPB (hydroxyl terminated polybutadiene) propellants on temperature sensitivity, mechanical properties and performance values. Aluminum (Al) content was ... -
Oxidative desulfurization of cayirhan lignites by permanganate solution
(2008)Unless important developments record new and renewable energy sources, the role of fossil fuels as an energy resource goes on. It is possible to detect sulfur, heavy metals, and tracer elements such as arsenic and selenium ... -
Effect of the activator type and catalyst/activator ratio on physical and mechanical properties of cast PA-6
(2008)The aim of the study is to produce suitable unfilled cast polyamide-6 composition exhibiting optimum mechanical, physical, thermal and electrical properties with anionic polymerization mechanism. Sodium lactamate was used ... -
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 ... -
River water quality model verification through a GIS based software
(2009)Research and development attempts on water quality models created valuable resources in the sense of model calibration and verification techniques. Recognizing the current degree of pollution in rivers and the importance ... -
A parameter identifiability and estimation study in Yesilirmak River
(2009)Water quality models have relatively large number of parameters, which need to be estimated against observed data through a non-trivial task that is associated with substantial difficulties. This work involves a systematic ... -
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 ... -
Genome response of model invertebrates and vertebrates species to stress agents in the environment
(2010)The genome response of model invertebrate and vertebrate species to stress agent in the environment was studied. The both group of species were collected from contaminated water stations along Marisa (Kemera) and Chaya ... -
Degradation of poly(vinyl chloride) onto KF-Al 2O 3
(2010)g-Alumina coated with potassium fluoride, KF-Al 2O 3 proved dehydrochlorination of poly(vinyl chloride), in tetrahydrofuran. The molecular changes was observed in the accurance of polyene sequence distribution by using ... -
The orientational behaviour of some aminoanthraquinone dyes in E8 and ZLI-1132 nematic solvents and effect of addition of carbon nanotubes
(2011)Guest-host liquid crystal displays have been widely utilised because of their many advantages such as colour, wide viewing angle and high brightness. For practical guest-host applications, it is important to choose dyes ... -
Light-scattering determination of visco-elastic and electro-optic parameters of azo and anthraquinone dye-doped liquid crystal molecules and consistent neural network empirical physical formula construction for scattering intensities
(2011)In this paper, we achieved two aims. Firstly, laser light-scattering intensities in methyl red (MR) azo and disperse red (DR) anthraquinone dye-doped nematic liquid crystal (NLC) molecules were measured versus scattering ... -
Examination of sulphonated maleic anhydride-alt-styrene copolymer membrane's properties by proton exchange membrane fuel cell
(2012)The most important element of proton exchange membrane fuel cell (PEMFC) is the proton-conduction properties of polymeric membranes. Polymeric membranes that can be compatible with PEMFC were synthesized using maleic ... -
Assessment of the sediment toxicity in Bulgarian and Turkish rivers using the biomarkers in chironomus riparius Mg. (Diptera: Chironomidae)
(2012)As a model organism we used Chironomus riparius Mg. - a widely distributed species that can be reared in the laboratory conditions and has excellent salivary gland chromosomes. The study showed that the genome at cytogenetical ... -
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 ... -
An artificial neural network model for the effects of chicken manure on ground water
(2012)In the areas where broiler industry is located, poultry manure from chicken farms could be a major source of ground water pollution, and this may have extensive effects particularly when the farms use nearby ground water ... -
A kind of energy storage technology: Metal organic frameworks
(2012)Abstract- For last fifteen years energy has been transferred by using electricity. As an energy carrier electricity has some disadvantages like its wire need for transportation and its being non-storable for large amounts. ... -
Fabrication and characterization of gold-nanoparticles/chitosan film: A scaffold for L929-fibroblasts
