This paper is reporting the data of a preliminary study on heavy metals distribution in fluid and solid phases involved dry classified aluminium hydroxide production through Bayer process. For released phases, main source contamination bauxite its mineralogical soluble or insoluble alkaline solution. It was shown that predominant way to transfer contaminating elements particles occlusion very f...

in this article, we have investigated the role of dimethylamine (dma), tributylamine (tba), triethanoleamine (tea), trishydroxymethylamine (trizma), and hexamethyleneterraamine (hmta), in the formation of zeolitic compounds. the experiments were carried out in acidic and basic media using si/al< 10 and si/a1>10. the structure of the resulting synthetic zeolites were similar to natro davyne, amm...

Surface PEGylation of nanoparticles designed for biomedical applications is a common and straightforward way to stabilize the materials for in vivo administration and to increase their circulation time. This strategy becomes less trivial when MRI active porous nanomaterials are concerned as their function relies on water/proton-exchange between the pores and bulk water. Here we present a compre...
