More and more nanometer materials are being developed, and presenting a great application foreground in biology, medicine, national defense and daily life[1-3].
Up to now, most researches of nanometer technique are only focus on developing nanophase materials and nanometer device with high sensitivity or high performance, powering them can still be challenging.

Results illustrate that the anaerobic bacteria can degrade organic materials effectively in wastewater at shorter HRT.
Effect of OLR on the bio-hydrogen production and pH In the malasses as raw materials remarkably lead to the variation in characteristics of wastewater and thus no corresponding linear relationship between HRT and OLR existed.

(a) (b) (c) (d) Figure 3- Load history captured by oscilloscope for full size Charpy test specimen 6 Material properties The material under investigation was X100 grade gas pipeline steel (36" O.D×19mm W.T).
The preliminary results from this research suggest that correction factors of at least 1.3 to 1.4 (140J/112J for sub-sized specimen, 279J/196J for full size specimen) may be required for extrapolating the semi-empirical relations calibrated on less tough pipeline material to calculate the Charpy toughness for crack arrest in X100 pipeline steel.
This is because of the high initiation energy for tougher pipeline steels which has not been accounted for in the predictive models tuned on lesstough materials (with less crack initiation energy).

Carbonation reactions clearly illustrate this phenomenon, as can be shown by the following equation using wollastonite (CaSiO3) as starting material: 1 CO2 (g)+1 CaSiO3 (s)=1 CaCO3(s)+1 SiO2 (am) (1) Recent attempts are made to emulate natural processes by producing calcium carbonate cement derived from the combination of seawater, calcium, and magnesium with carbon dioxide [2].

According to the case that mass concrete in solid sections of lower pylon column of Jiashao Bridge was easy to crack in construction because of the bigger section size, larger content of cementitious material and lower water binder ratio, the temperature and thermal stresses distribution of mass concrete was simulated and temperature control scheme was adjusted constantly based on the results of field temperature monitoring.
Because of the bigger section size, larger content of cementitious material and lower water binder ratio, improper handling in construction may easily result in large temperature stress and shrinkage stress.

This analytic result is used as the basic material for the design of the injector.
This analytic result may not only be used as the basic material for injector designs of the future, but it could also be applied to a number of areas requiring such a responsiveness.

Introduction Requirements regarding reduction of cars’ fuel consumption play a key role in automotive as they make cars lighter by application of more and more resistible materials.
Application of this kind of materials considerably reduces construction mass thanks to high durability.
