Preparation and Application of Nano Ce-Zr Mixed Oxides Supported H3PW12O40 in Nitrogen Oxide Capture and Decomposition Lin Cheng and Rui Wanga School of Environmental Science & Engineering, Shandong University, Jinan 250100, China aree_wong@hotmail.com Keywords: Nano Ce-Zr mixed oxides, H3PW12O40, NOx, Adsorption-decomposition.
Meanwhile, when the particle size of Ce-Zr mixed oxide was reduced, especially when the size decreased to around 100 nm, the material became nanophasic, and would provide more active sites for gas-solid catalysis [11].

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.

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.
Table 1 Retrofit schemes of RC frame T-beam specimens Specimen Sprayed FRP type Pre-damaged control Thickness of Spraying layer TL-1 - - - TL1-BF1-U BFRP undamaged 4.5mm TL1-BF1-D1 BFRP Δy 4.5mm TL1-BF2-D1 BFRP Δy 7mm The material properties of the basalt fiber and the resin applied to the spraying process in this test are shown in Table 2 and Table 3.

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.

Generally, such materials as surface soil, chemical fertilizer, organic castoff, green manure and nitrogen-fixing plant are used to directly improve soil and re-improve the newly-covered soil.
Alternatively, re-hardening of soil may be realized via growth of vegetation roots, concentration & dispersion of nutritive materials, and activity of microorganism[4].

However, researches about morphology structure health condition of lake basin not only reveal the potential health condition of lake system, but help to identify the key factors which leads to lake ecological degradation [15].
Therefore, the process in both water and sediment is not only material basis and power to shape basin geometry, but a source to maintain its vitality.
