Investigation into Hydrogen Production in Hydrolysis of Sodium Borohydride in the Presence of Co-La-B Catalyst Chang Jing1,2,a and Du Fanglin1,b,* 1College of Materials Science and Engineering, Qingdao University of Science & Technology, Qingdao 266042, China; 2College of Recourse and Environment, Qingdao Agricultural University, Qingdao 266109, China achangjing1103@yahoo.com, bfl_du@yahoo.cn, * Corresponding Author Keywords: sodium borohydride, hydrogen,lanthanum , activation energy Abstract.
The hydrogen is often stored by high-pressure tank, adsorbents and hydrogen storage materials.
Among them, chemical hydrogen storage method is preferred to because the purity of generated hydrogen, the rapidity in hydrogen production and the portability of hydrogen storage materials is better than the other methods.

In this paper,by using cement, sand and other materials to make the M5, M7.5, M10 three strength grades cement mortar, the effect of water cement ratio and cement dosage on the strength of cement mortar was studied.
Introduction According to the similarity theory in the design of indoor model test,similar materials were determined, then the ratio of similar materials was changed to simulate the performance of different geological structure[1].
Acknowledgement The research project was supported by national natural science foundation of China (51204215) and Doctor special research fund of colleges and universities(20134321120004) and also funded by Hunan province science and technology plan projects (2013SK3150).

Commonly 6 test specimens only have been produced and tested: MT-07-01, MT-07-02, MT-07-03 and MT-08-01, MT-08-02, MT-08-03, but in the case of steel (unlike other non-metallic building materials) 6 tests are sufficient and usable test number for the satisfactory evaluation.
(I-profile) 346.6 456.8 213.4 18.2 From the comparison of of failure mechanisms seen on the failed specimens, it can be deducted, that from the viewpoint of the basic behaviour historical steel is very similar to the recent materials.

Spectral selective absorbing coating, by definition, is the coating material of spectral absorption selective.
A material of having spectrally selective absorption characteristics is a composite material, i.e. composed by 2 parts materials of the absorption solar radiation and reflection infrared spectroscopy.

Sacrificial polymer materials such as photoresist and polyimides are used for patterning and/or passivation steps [1,2].
Typical challenges in removing these materials include long process times, short bath life, corrosion, sludge formation, and filter clogging.

Experiment Materials.
PTFE and silicone are both hydrophobic materials, and therefore, the increased surface hydrophobicity is primarily a result of the surface roughness of the silicone/PTFE composites.

However, a study on FSW Mg/Al dissimilar materials was reported less.
The presence of liquid between Al and Mg can cause the two materials to separate during stirring.
