Combination of oven and microwave and only oven are two ways to study municipal sludge,and it investigates whether different size, microwave drying pretreatment, pretreatment time and oven temperature characteristics have effect on drying characteristics. The results shows that: using microwave to dry sludge need short time, the drying rate is fast, combination of oven and microwave has higher drying rate and lower energy consumption than only oven.

After the invention of mesoporous, the chiral mesoporous materials had been regarded a hot research issue. Inspired by the chiral phenomenon, in this investigation, we presented several aspect of chiral mesoporous from its first appearance, especially stated the template that could be used to prepare chiral mesoporous, including chiral template and achiral template, besides, the different mechanism of some distinguished scientists’ works were introduced, and some application of these material were introduced such as catalyst, HPLC stationary phases and many other fields.

Ni doped amorphous mesoporous titaniasilica with Ti/Si mass ratio of 0.8 (NiTiO2SiO2) was synthesized, and this material was characterized by a combination of various physicochemical techniques, such as N2 physisorption, diffuse reflectance UVvis, X-ray diffraction, and FT-IR. Interestingly, and some of this material showed sphere shape.
