The composite material 1-ethyl-3-methylimidazolium methanesulfonate ionic liquid in Syloid AL-1FP silica shows unprecedented water vapor sorption equilibrium properties. Equilibrium data were recorded at different loads of ionic liquid in the silica support (from 1.8%w to 60%w). At loadings>1.8%w, all the composites show type 3 isotherm, therefore conserving the vapor-liquid equilibrium of the bulk ionic liquid/water binary system but with increased ... Read more

Effect of employing solar hybrid adsorption desalination-cooling system (ADCS) at the Egyptian weather has been investigated using TRNSYS software employing meteorological data of Assiut city at Egypt. A theoretical model of a semi continues hybrid ADCS employing silica gel-water has been used. Maximum specific daily water production (SDWP) is found to be about 10 m3/ton of silica gel. Moreover, maximum ... Read more

In this paper, a new hydromatrix power generation unit is presented. This presented hydromatrix power unit is aimed to convert the water movement in the main river branches into electrical power. It is found that the generated power based on the proposed hydromatrix power can be reached 5 GW/h in Egypt. the proposed hydromatrix power unit based on the under ... Read more

ABSTRACT: This paper is aimed at estimating the possible energy generation by wind in high rise buildings. The 71-strory, 310m height Pearl River Tower in Guangzhou, China is selected as a case study. The tower being designed as office building for Chinese National Tobacco Company (CNTC) headquarters has a total gross area of 210,000 m2 of which 40,000 m2 for ... Read more
