Ricin is a highly toxic material, which can be extracted from semenricini.
Due to the extensive raw material sources and the simple extraction process, it is very possible for ricin to become one of the attack means for terrorist.
In January 2003, the Britain police ferreted out some recin and the relevant raw materials and equipments in a house, and discovered that those terrorists were about to assault with recin in London.
Among those currently reported extraction methods, solution extraction is relatively simple, and all the desired raw materials and equipments can be obtained in the market, so through a small amount of money and very simple process, it is very easy to obtain a large amount of high toxic crude ricin.

At the present, organic materials like foamed polystyrene board, polystyrene mortar, etc are widely used as the main thermal insulating materials in the external walls of buildings.
In comparison, the resources of inorganic materials are very ample in our country, and great progresses of inorganic thermal insulation materials in some critical problems make them the most likely substitute for organic heat-resisting materials in exterior walls.
Durability Inorganic heat-insulating materials like silicate, sulfur aluminate etc have the same material with the main structure of buildings.
Conclusions Sulfur aluminate heat insulating materials is a new generation high effective inorganic heat insulating materials developing from traditional foamed silicate heat insulating materials.

Research shows that when ceramic materials are replaced by nano- materials, the mechanical properties of materials can be greatly improved, mainly in the following three aspects: 1) the breaking strength is greatly improved; 2) the fracture toughness is greatly increased; 3) the heat resistance is greatly improved.
The application of nano materials to anticorrosion coating greatly improves the anti-corrosion coatings and open up new ways to anti-corrosion coating and new areas of application of nano-materials.It is a major innovation of anti-corrosion coating.
