Minimal research exists for non-chromatographic separations of rare-earth metallofullerenes containing di-metallic (M2), di-metallic carbide (M2C2), and tri-metallic nitride (M3N) clusters trapped inside fullerene cages. Herein, we demonstrate a non-HPLC method (i.e., SAFA, Stir and Filter Approach) for purifying Er3N@Ih-C80, a rare-earth, metallic nitride clusterfullerene. We describe a strate...
In the application of UREX+1 process, technetium will be separated together with uranium and iodine within the first process step. After the separation of uranium, technetium and iodine must be immobilized by their incorporation in a suitable waste storage-form. Based on recent activities within the AFCI community, a potential candidate as waste storage form to immobilize technetium is to alloy...
Waste distribution and compaction at the working face of municipal waste landfills releases mercury vapor (Hg(o)) to the atmosphere, as does the flaring of landfill gas. Waste storage and processing before its addition to the landfill also has the potential to release Hg(o) to the air if it is initially present or formed by chemical reduction of Hg(II) to Hg(o) within collected waste. We measur...
Background: A biomaterial used in oral cavity should not become toxic, irritant, carcinogenic, and allergenic. Chitosan represents a new biomaterial in dentistry. Purpose: To examine the toxicity of chitosan from tiger prawn shell waste on cell culture with MTT assay. Methods: Chitosan with concentration of 0.25%, 0.5%, 0.75% and 1% was used in this experiment. Each sample was immersed on eppen...
16 There has been growing interest in establishing food waste prevention and recovery 17 programs throughout the world. The drive to target food waste stems from increasing concerns 18 about resource conservation, food security, food waste’s environmental and economic costs, and 19 a general trend in the waste management industry to transition to more sustainable practices. 20 Here the drivers ...
The aim of this study is the comprehensive planning for integrated management of solid waste at the industrial parks. The share of each industrial group including food, metal, chemical, non-metallic minerals, textile, electrical and electronical, and cellulose industries were 48.2, 14.9, 6.7, 22, 0.9, 0.6, and 6.5 percent, respectively. The results showed that nearly half of total industrial wa...
Grounding Waste: Towards a Sociology of Waste Networks. This article contributes towards building a sociology of waste. It advances a network analysis framework to understand the position and role of the various actors involved in waste governance in Ireland, North and South. It is the state at the EU and national levels that has sought to deal with waste within the competing sustainability and...
