Gold catalysts on TiO2-modified silica gel for the selective cyclopentane oxidation to cyclopentanone Lixin Xu1, a, Chuanfeng Sun1, b, Jie Li1, c, Guangyuan Chen1,d 1School of Chemistry & Chemical Engineering, Anhui University of Technology, Ma'anshan 243002, PR China aLxxu@ahut.edu.cn, bscf-wj@163.com, ccnen1204008238@sina.com.cn, d171985724@qq.com Keywords: gold catalyst; cyclopentane oxidation; cyclopentanone; silica gel Abstract.
Mildly acidic silica gel is a cheap catalytic support material highly resistant to the acidic medium and considerably applicable in cyclopentane oxidation under a harsh reaction conditions.
Experimental 2.1 Materials and Methods.
As given in Fig 2, almost monodispersed black dots indicate the existence of Au nanoparticles although the TiO2/SiO2 support material displays a strong background of the images.
Entry 1 and 2 of Table 1 demonstrate that the Au species play a key role for the cyclopentane oxidations since no oxidation products were detected when the reaction was attempted in the absence of gold.

Energy and material exchange in the forest ecosystem, transfer from one library to another, and form a series of forest ecological systems.
Parallel computing capacity of the genetic algorithm also plays a key role in solving the complexity of ecosystems.
Thus, although the energy flow of some material is small, it has high quality.
Complex networks in ecosystem is an effective method to study complex ecological phenomenon from the systematic perspective and complex network technology, which reveals the whole emergence and vulnerability of forest ecosystem function by network simulation to material, energy and information flow in an between ecosystem.

The chemical technology, environmental measures associated with the curing chemistry has become the key of harmless manganese slag treatment.
Experimental Materials.
However, when the ratio was 90%, the initial and final setting time was very long, which could not meet the requirements of practical engineering application; while the ratio was 60%, the initial and final setting time was appropriate.
Calcium silicate hydrate gel material quality had been improved, and the composition was optimized.
Hence, the number of cementitious material was significantly increased, and the interface structure of gel and aggregate were improved.

The as-synthesized catalysts had been investigated by catalytic activity tests, and key improvements were made to BTEX degradations.

Experimental research on seismic performance of pre-damaged RC frame T-beam strengthened with Sprayed BFRP Rui Gao1, a, Qian Gu1, b, Chengfang Sun2, c and Yujia Peng1, d 1School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan430070, P.R China; 2City College, Dongguan University of Technology, Dongguan523106, P.R.China agaorui3333@126.com, bguqian218@126.com, c13412969219@139.com, dtmpyj@126.com Key words: sprayed BFRP; pre-damaged; reinforced concrete(RC) frame T-shape beam; seismic performance Abstract: This experimental program was designed for investigating the seismic performance and reinforcement effect of pre-damaged RC frame T-beams reinforced with sprayed basalt fiber reinforced polymer (BFRP).
Sprayed FRP rehabilitation can repair and reinforce building structure damaged by earthquake rapidly, and there are many unique advantages: reinforcement material solidify and strengthen fast, low cost, less construction process, short cycle, and light construction equipment.
Now in the field of spraying FRP structural rehabilitation, glass fiber is the chopped fiber researched and applied more, but sprayed GFRP has a certain characteristic of brittle fracture and poor durability; the overall performance of sprayed CFRP is excellent, but reinforcement material cost a lot.
Before spraying, concrete surface dust must be blew off with high pressure air of spray gun, then spraying resin undercoat, after curing spraying chopped BFRP, a ridged aluminum compaction roller is used to force out any entrapped air voids and to work the material into a consistent thickness.
