Analysis results shows that the preparation method has great influence on the morphology and pore structure, and further influence the hydrodesulfurization activity.
Bulk HDS catalyst does not use a porous support, and contains very high amount of active components, which allows the entire structure to be composed of the active materials.
The three-dimensional porous structure can supply with more channels for participating molecules to contact the active sites.
The catalyst with higher surface area and more developed porous structure has higher HDS and HDN activity.

Pattern collapse is more pronounced for non-rigid nanostructures such as photoresist and low-k dielectric structures, or structures with very high aspect ratios (AR).
Results and discussions For patterned substrates, as structures are fixed at one end, the bending and aggregation of structures result from the competition between capillary forces and the elastic restoring forces.
With optical reflectance measurements, the nanoscale water penetration depths have been measured and the wetting transition from complete wetting to the superhydrophobic state has been determined by varying the surface chemistry with different silanes [6].
For structures collapsed after wet processing, the usage of dry treatments to break the covalent bonds formed between bridging structures has a potential to repair pattern collapse.
The inset shows atomic structures of a relaxed nanowire after plastic deformation.

Preparation and Its Application Performance of Backfilling Cementation Material Based on Blast Furnace Slag Shugang HU a Haili NIU b Xianjun LU c College of Chemistry and Environmental Engineering, Shandong University of Science and Technology, 579 Qianwangang Road, Economic and Technical Development Zone, Qingdao, Shandong Province, P.R.China. 266510 ahusg8921@163.com, b nhl004@163.com, cluxianjun@vip.sina.com Key words: blast furnace slag; backfilling; cementation material; application performance Abstract: The blast-furnace slag （BFS）has been characterized by chemical and phase composition to evaluate its hydration reactivity.
It has high potential activity for its glassy structure, so its use to prepare new filling cementation material is possible.
Blast-furnace slag is a glassy structure material with high potential activity for being high temperature smelted, so it can be used as base material of cementing material preparation.

Results indicated that hydration products included C-S-H and geopolymer, and both of them were amorphous although there were differences in their structure and morphology.
Conclusion Hydration products of compound binding material of alkali activated metakaolin and ground blast furnace slag are C-S-H, geopolymer, and their coexistence phase, and all of them are amorphous although there are differences in their structure and morphology.
