Synthesis of rutile titania powders: Agglomeration, dissolution, and reprecipitation phenomena
Rutile titania powders were synthesized via a sol-gel/hydrothermal process using nitric acid as the catalyst. A molar acid to alkoxide ratio of 10 and a water to alkoxide molar ratio of 250 produced 100% rutile powders when precipitated below 45 °C. Higher temperatures yielded initially either anatase or mixtures of anatase and rutile. Spherulitic growth produced cauliflower-shaped agglomerates...
متن کاملManagement of Kitchen Waste Material through Vermicomposting
India produces around 3000 million tones of organic waste annually. This huge volume of waste(s) comes from agriculture, urban and industrial sources and also from domestic activities. Utilization of this waste material for productivity process is important for both economical and environmental reasons. In the present study an effort has been made to asses the efficacy of E. foetida (red tiger ...
متن کاملThe Widespread Occurrence of Coupled Carbonate Dissolution/Reprecipitation in Surface Sediments on the Bahamas Bank
Using two complimentary approaches (pore water advection/diffusion/ reaction modeling and stable isotope mass balance calculations) we show that carbonate dissolution/reprecipitation occurs on early diagenetic time scales across a broad range of sediments on the Great Bahamas Bank. The input of oxygen into the sediments, which strongly controls sediment carbonate dissolution, has two major sour...

New energy value chain through pyrolysis of hospital plastic waste
In this paper, the evolution in thermochemical behaviours of hospital plastic wastes and changes in chemical composition and characteristics of pyrolysis liquid products have been investigated by using different fixed bed reactor scales. The main objective is to identify the critical technical parameters enabling thermochemical process adaptation in function of raw materials chemical structure,...
