the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Extraction and characterization of pectin from Saba banana [Musa ‘saba’(Musa acuminata x Musa balbisiana)] peel wastes: A preliminary study

Saba banana, Musa ‘saba’(Musa acuminata x Musa balbisiana) peel is an underutilized waste from processed banana manufacturing in the Philippines. The feasibility of saba banana peel pectin for use in food processing was assessed. Pectin from saba banana peel was extracted under two different extraction conditions. Pectin extraction was carried out using hydrochloric acid (0.5N, pH 1.5) and citr...

Biomimetic Aminoacylation: Optimization of Reaction Conditions

Optimization of reaction conditions and effect of catalyst type on product distribution in Cyclooctene oxidation

Oxidation of cyclooctene was studied in presence aqueous hydrogen peroxide (30%, v/v) over nano iron oxide. The catalyst prepared by microemulsion method and characterized using various techniques including XRD, TEM and BET techniques for evaluating phase, structure and morphology and surface area. In this study, we investigated the effects of varying the catalyst content, reaction temperature,...
