The positive effects and response of the direct communication between community and university in solving a lots of problems that faces industry in Palestine

The area under study is East of Dura city which is 6 km2 and is very rich in groundwater and springs. The aquifer is very shallow and it is of unconfined aquifer. The groundwater flow is from west and north west towards east and south east. The chemical analysis of the water in the area shows that the water is good for irrigation purpose, but it is...

Single crystals of hydrogen‐vermiculite have been synthesized at room temperature by ion exchange from Na‐vermiculite using 1M acetic acid for one week. The ionic conductivity was measured and shown to be much lower than that of many other monovalent cations in the same host lattice. Its enthalpy of motion is also much lower. These marked diff...

We have made an investigation of the ion transport properties of single crystals of the naturally occurring clay vermiculite in order to elucidate the mechanism of conductivity including the predominant charge carrier . Measurements of the ion conductivity, magnetic susceptibility and x-ray lattice parameters of ionexchanged samples strongly sugges...

Synthesis of hydrogen vermiculite and Characterization using Impedance spectroscopy and Diffraction Techniques

A simple introduction to general and organic chemistry concepts in a very simple and well organized shape

Ion Transport Study using impedance spectroscopy and Diffraction Techniques

Discussion of the basic raw materials and all chemical reactions involved in preparation and syntheseis of soaps and detergents.

Novel guest- host compounds, based on single crystal vermiculite, were synthesized by diffusive techniques through a new hydrogen vermiculite. Single crystals were chosen because of the ease of characterization. An investigation of the ion transport properties of these single crystals was done to determine the mechanism of conductivity including th...

Single crystals of hydrogen vermiculite were synthesized at room temperature by ion-exchange from Na-vermiculite using 1 molar acetic acid for one week. The protonic transference number has been determined as unity in concentration cells. The protonic species in the interlayer region can undergo acid-base reactions as well as ion exchange reactions...

In my master study I discussed the rates of decomposition of β-diketones and their uranyl and thorium complexes with halates by following the change of their concentration with time spectrophotometrically. The rate constants were determined after establishing the order of each reaction with respect to each reactant. The reaction rates increase line...
