Polyvinyl alcohol (PVA) is a typical refractory organic pollutant with low biodegradability and high molecular weight.This paper presents data on the radiolysis of PVA in aqueous solutions by using ionizing radiation.Response surface methodology with Box-Benhken design of experiment was applied to analyze the interact…
The novel phenolic Mannich bases 2,2'-(2-hydroxy-4,5- dimethylbenzylazanediyl)diethanol (1) and 2-((2-(4-(2-hydroxy-4,5- dimethylbenzyl)piperazin-1-yl)ethylamino)methyl)-4,5-dimethylphenol (2) have been synthesized in good yield by using a microwave-induced technique from 3,4-dimethylphenol and corresponding amines in…
La caracterizacion de la propagacion de grietas se basa en la teoria clasica de la mecanica de la fractura elastica lineal, la cual ignora cualquier efecto tridimensional en la propagacion de la grieta. Factores tales como el espesor de la probeta y la curvatura del frente de la grieta no son considerados. El fenomeno…
David Cowan is a Hydraulics Engineer with ITT Goulds Pumps responsible for applied research and hydraulic design of engineered API process pumps.His responsibilities include the development and analysis of new and existing hydraulic products through traditional and computational methods.He is also jointly responsible…
The objectives of this research were to analyze the physical and mechanical properties of Oriented Strand Board (OSB) prepared from steam treated betung bamboo (Dendrocalamus asper) strands under various adhesive combinations. The strands were steamed at 126 °C for 1 h with the pressure of 1.4 kg cm-2 prior to be blen…
Investigations were carried out to study the effects of heat treatment on the mechanical properties of medium carbon steel. Samples of medium carbon steel were examined after heating at 9000C and soaked for 60 minutes in a muffle furnace and quenched in oil. The mechanical behavior of the samples was investigated usin…
In the process of hot dip galvanizing of Si and Mn added high tensile strength sheet steels, the selective surface oxidation of Si and Mn causes coating defects. One of the promising methods overcoming this problem is oxidation-reduction process. The steel surface exposed to an oxidizing atmosphere will react primaril…
Property prediction models based on the group-contribution+ (GC+) approach have been developed to provide reliable predictions of pure component properties together with uncertainties of predicted property values which is much needed information in performing chemical product and process design and analysis of sustain…
In this work ,The thermal comfort properties of polyester and bamboo blended woven fabrics have been studied in relation to %of component fibers in blends ,pick density and weave .The objective was to determine the influence of fabric factors such as the constituent fibers ,pick density and weave characteristics on th…
It has become increasingly clear that the cellular microenvironment, in particular the extracellular matrix, plays an important role in regulating cell function. However, the extracellular matrix is extraordinarily complex in both its makeup and its physical properties. Therefore, there is a need to develop model syst…
Using Reversible Addition-Fragmentation chain Transfer (RAFT) polymerization as model technique for reversible deactivation radical polymerization (RDRP) methods, we explored the synthesis of complex non-ionic amphiphilic water-soluble polymers in general, and of associative telechelics in particular. Via straightforw…
Density functional theory and GGA-PW91 exchange correlation function were performed to simulate the bonding behavior of hydroxyl and epoxy groups on the graphene surface. We compared the different binding energies for two epoxy groups, as well as one hydroxyl group and one epoxy group on all possible positions within…
Transmission-EBSD (t-EBSD) method is proposed as a new method for nano-scale microstructures analysis of materials. t-EBSD uses TEM thin foil specimen. Electrons transmitted through the specimen form EBSD patterns. A EBSD detector used for standard EBSD (s-EBSD) is used to acquire these t-EBSD patterns. The patterns a…
The properties and microstructures of Al2O3–SiC–ZrO2(ASZ) composite ceramics for solar thermal power generation were investigated.The composite ceramics were synthesized with α-Al2O3,partially stabilized zirconia(5.2% Y2O3 in mass fraction) and silicon carbide by a pressureless sintering technique.Influences of SiC an…
The effective use of bischofite in the salt lake area in China for magnesium oxychloride cement(MOC) as a building material is concerned. The MOC material should be improved for the long-term water resistance. However, there is no any systematic study on this aspect so far. This review paper summarized and evaluated r…
Nano-graphene oxide(GO) aqueous was prepared by oxidizing graphite according to Hummers method and ultrasonic dispersion.The effects of GO on the concrete properties doped with polycarbonate superplasticizer(PCs) were investigated by measuring the fluidity,viscosity and setting time of cement pastes,pore structure of…
soundness 0.5 mm ABSTRACT: The properties of blended cement with nano-SiO2 (NS) were experimentally studied. The silica, which is the major component of a pozzolan reacts with calcium hydroxide formed from calcium silicates hydration. The rate of pozzolanic reaction is proportional to the amount of surface area availa…
By means of alternating current electrochemical technique two crystalline copper(I) π-complexes with fluorine containing anions [Cu(L)CF3SO3] (1) and [Cu2(L)2(H2O)2](SiF6)2 · 2.5H2O (2) (L - 2-(allyl)-amino-5-methyl-1,3,4-thiadiazole) have been obtained and characterized by X-ray single crystal diffraction and Raman s…
Comfort is one of the most important aspects of all clothing. In this research an attempt has been made to finish the fabric with various softeners. Four different types of bleached fabrics like cotton, heavy cotton, P/ V blend, P/C blend were used for the study. These fabrics were treated with softeners like Anionic,…
SUMMARY. The objective of the present study was to prepare ceramic nanoparticles of a poorly aqueous soluble drug (piroxicam) to explore the relationship between particle size and dissolution profile. Ceramic nanoparticles were prepared by self-assembling of hydroxyapatite using colloidal precipitation technique, with…
