Inhomogeneous brittle materials contain numerous pre-existing microcracks, holes, inclusions, or other defects and under the shock wave compression they could be activated and growth due the local shear stress effect.
By "Birth and Death" method, elements whose temperature are in excess of material meltingpoints are killed and any other element not in excess of material melting points are activated. Therefore, dynamic simulation on metal melting and freezing is fulfilled.
Doping advanced coating with suitable inorganic antibacterial healthy additives activated by rare earth elements developed building coating for purifying harmful gasses in house microclimate. Then the properties and purifying mechanisms were suggested. Results indicate that building coating can purify VOC, NOx,NH3, etc in house microclimate, and can be used in the 21st century.
In this paper, survey of the key contents on this subject, focusing on the most well-known models based on kernel substitution, namely SVM, as well as the activated fields at present and the development tendency, is presented.
Adsorption of reactive brilliant red K-2BP on activated carbon developed from sewage sludge
Activated carbon was prepared from the sewage sludge of municipal wastewater treatment plant by chemical activation (activation reagent is ZnCl2) and was used for the adsorption of dye (reactive brilliant red K-2BP).
The results indicated that the activated carbon developed from sewage sludge (ACSS), which was mesoporous, possessed opened porous structures.
euphratica rapidly activated antioxidant enzymes after the onset of salt stress, which might reduce the accumulation of reactive oxygen species and the subsequent acceleration of lipid peroxide.
