Sealosafe A family of processes for encapsulating inorganic and organic wastes in a cementitious material suitable for landfill. The product, known as Stablex, is made from a cement and an aluminosilicate and may incorporate pulverized fly ash. Developed by C. Chappell in the United Kingdom in the 1970s and now operated in a number of countries. Offered by the Stablex Corporation, Radnor, PA. The environmental acceptability of the product has since been criticized. 

Encapsulation is the process of obtaining small solid nanoparticles, liquid nanodroplets or gas nanobubbles with a polymeric coating. We will give a historic account of some of the early work on encapsulating inorganic pigments and fillers with a polymer through (mini)emulsion polymerization. 

For microencapsulation of inorganic nanoparticles, preparation methods like in situ polymerization may be used [102]. However, these methods often require toxic organic solvents and surfactants. Furthermore, the removal of residual surfactants or solvents is needed, since they cause faults in the product An environmentally benign solvent like supercritical carbon dioxide can be used to encapsulate inorganic nanoparticles. But its use is limited because of the low... 

Figure 4.4 General synthetic strategy used for the elaboration of polymer-encapsulated inorganic particles through heterophase polymerization.

The encapsulated inorganic nanoparticles can be manipulated as if they were organic macromolecules. Significant advantage of CNDs that size, net surface charge and composition can be modified one variable at a time. Optimization of composite nanodevices permits several variables to be incorporated into modeling as needed.

Condensation of stoichiometric amounts of a tet-rathiol cavitand syntone 95 and its tetrachloride analog 96 in the presence of cesium carbonate by Scheme 2.160 has been used in [181, 182] to obtain a bis-cavitand covalent capsule (car-cerand) 257. The latter gives 1 1 cage complexes (carceplexes) with solvent and gas guest molecules as well as those with encapsulated inorganic cations and anions.
