A novel proton exchange membrane has been prepared using sulfonated poly(styrene-divinylbenzene) resin(SPSDR)–polyethylene(PE). The membrane is characterized by FT-IR, SEM and TGA/DSC. Water uptake, ...

This paper presents a detailed thermodynamical exergy analysis of an optimized MSF distillation plant based on the latest published thermodynamics properties of water and seawater software of the Massachusetts Institute ...

2-Dimethyl amino ethyl azide (DMAZ) has attracted much attention as a suitable liquid fuel replacement for monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) in propellant systems because, in contrast ...

In this research, a Dispersive Liquid-Liquid MicroExtraction (DLLME) method coupled to UV-vis spectrophotometry was developed for the indirect determination of silver ion. The method is based on the catalytic effect ...

Hydrocyclones have been used as an operational tool to separate liquids from solids in different industries for more than 50 years. Considering the importance of this issue, many experimental and ...

Several heterocyclic bioactive fluorescent 3-alkyl-3H-pyrazolo[4,3-a]acridin-11-carbonitriles were conveniently synthesized from ...

A mathematical model considering mass and momentum transfer was developed for simulation of ethanol dewatering via pervaporation process. The process involves removal of water from a water/ethanol ...

The sorption of thorium and uranium ions by functionalized SBA–15 mesoporous silica materials with Schiff base ligating groups N–propylsalicylaldimine (SBA/SA) and ethylenediaminepropylesalicylaldimine (SBA/EnSA) from ...

Dyeing wastewaters are one of the most common pollutants that cause many problems for public health and environment due to dermatitis and skin rashes, cancer production, mutagenesis, etc. Thus, treatment of these ...

Multi-Walled Carbon Nanotubes (MWCNTs) surfaces were serially modified by the annealing treatment under Helium flow at 1000oC, the nitric acid treatment and again the annealing treatment under same conditions ...

In this study, spectroscopic properties of the single-walled boron-nitride nanotube (SWBNNT) –a semiconductor channel in molecular diodes and molecular transistors–have been investigated under field-free and various applied ...

A new aromatic diamine monomer containing ether linkage based on the phenanthrimidazole ring, ‎1,1´-(4,4´- oxy bis(1,4-phenylene))bis(2-(4-aminophenyl)-1H-phenanthro[9,10-d]imidazole) was synthesized through ...

Current catalysts for the alcohol oxidation in fuel cells (typically noble metals-based) are susceptible to poisoning with intermediates like CO. Hence we decided to find superseded catalysts for methanol ...

Sodium acetate catalyzed the multi-component reaction of acetophenone, aromatic aldehydes, and acetoacetanilide in the water-ethanol mixture (1:1) at ambient temperature via Claisen-Schmidt condensation ...

An efficient and eco-friendly protocol for the synthesis of quinoxaline derivatives employing a condensation reaction between 1,2-diketone and 1,2-diaminobenzene derivative has been developed. The reaction of  1,2-diketone ...

Hexagonal mesoporous silica (SBA-15) was prepared and then functionalized by(3-mercaptopropyl)trimethoxysilane. The obtained 3-mercaptopropyl functionalized SBA-15 (SBA-Pr-SH) was then oxidized ...

A new derivative of Cyclotriphosphazene with xanthydrol as the oxygen-containing ligand was synthesized. Firstly Hexaclorocyclotriphosphazene was obtained Hexaclorocyclotriphosphazene from ammonium ...

Plasticized sulfur/montmorillonite nanocomposites were prepared by the melt-blending method and the dispersion of montmorillonite (MMT) and the mechanical properties of the nanocomposites were studied. Natural sodium ...

A novel method for the preparation of α-zirconium phosphate (ZrP) nanoparticles as an eco-friendly and recyclable heterogeneous catalyst was studied. Polyethylene glycol (PEG) was ...
