Solar Cooling System Preserves Food Without Electricity An eco-friendly and cheap cooling system developed by a Mexican researcher uses solar energy to maintain temperature of food and water at nine degrees Celsius for three months. Refrigerating systems have been under the spot light ever since they were found guilty of polluting the atmosphere with the Chlorofluorocarbons…
Babak Ahmadi *, Mohammad Shekarchi Construction Materials Institute, Department of Civil Engineering, College of Engineering, University of Tehran, Tehran, Iran abstract Natural zeolite, a type of frame-structured hydrated aluminosilicate mineral, is used abundantly as a type of natural pozzolanic material in some regions of the world. In this work, the effectiveness of a locally quarried…

Characterization of Cement Pastes Containing Natural Zeolite as a Pozzolanic Admixture Abstract A possible use of natural zeolite originating from a mining area in South Slovakia as a pozzolanic material suitable for the partial cement replacement in composite production is studied. Measurement of chemical composition of natural zeolite is performed using XRF analysis. The particle…
Natural Clinoptilolite and Chabazite as Carrier for Antibacterial Agents of Cetylpyridinium Chloride (CPC) and Silver Abstract Natural clinoptilolite (Cli) and chabazite (Cha) were used as the carrier for two types of antibacterial agents: cetylpyridinium chloride (CPC) and silver cations (Ag). CPC-zeolites, Ag-zeolites and CPC-Ag-zeolites were characterized by Energy Dispersive X-ray (EDX) analyzer and Fourier Transform…
Study on the Effect of Adding Zeolite and other Bio-Adsorbance in Enhancing the Quality of the Palm Based Vermicompost Abstract This research work deals with the production of vermicompost from empty fruit bunch (EFB) blended with cow dung using an epigeic earthworm known as Eudrilus Eugeniae. The vermicomposting mixture was carried out in a humid…
The Study on Zeolite Column Adsorption of Groundwater Nitrate Abstract By zeolite column adsorption test process of nitrate pollution of groundwater, the research of three different inlet velocity of nitrate nitrogen removal, and the roles of nitrite nitrogen accumulation, zeolite adsorption of ammonia nitrogen and the influence of pH value changes, the results show that…
Preparation of Compound Clinoptilolite Filter Material and Performance of Ammonia Nitrogen Removal Abstract This experiment use natural clinoptilolite powder as main materials to prepare the large specific surface and high porosity spherical compound filter material by adding adhesive and pore-forming agent etc.This compound filter material has favourable effect when treating sanitary wastewater. The static adsorption…
University of Minnesota developed a method to improve biofuel production American scientists developed computer screening method that identifies materials able to improve biofuel production process. Research team from the University of Minnesota in cooperation with Argonne National Laboratory led a number of researches that would improve biofuel production efficiency. Scientists offer to use alumino silicate…
The water protection – Nikos Lygeros Translated from the Greek by Athena Kehagias Since there is at last, a formal consultation regarding the water protection from agricultural fertilizers, the role of the zeolite must be promoted in this process. More specifically, it regards the approval of: Code of Good Agricultural Practice for Protection of Waters…
