Multi-wall Carbon Nanotubes as a Support for Platinum Catalysts for the Hydrodechlorination of Carbon Tetrachloride and Dichlorodifluoromethane Magdalena Bonarowska 1,a , Kuan-Nan Lin 2,b, Marta Legawiec-Jarzyna 1,c, Leszek Stobinski 1,d, Wojciech Juszczyk 1,e, Zbigniew Kaszkur 1,f, Zbigniew Karpiński 1,g and Hong-Ming Lin 2,h 1 Institute of Physical Chemistry, Polish Academy of Sciences, Kasprzaka 44/52, 01-224 Warsaw, Poland 2 Department of Materials Engineering, Tatung University, 40, Chungshan N.
In this respect, recent work on the catalytic hydrodechlorination of chlorobenzene over Pd, supported on amorphous and structured carbons in he form of graphitic carbon nanofibres, showed irreversible losses of activity of both catalysts.
It appears that the structured carbon substrate is more effective in stabilizing metal activity..

In addition, there are also many scholars found that the perovskite type oxides also have the good cycle performance, which can react fully with natural gas in the cycle of the experimental test, and remain stable structure after cycle many times.
The structure of the CLC reactor has very important influence for the combustion process.

a b Fig. 1 GB structure in the planes (001) - (a),(100) - (b) Simulation of Grain Boundary Diffusion in a Pure Copper To evaluate the proposed model quality the double product of GBD (δDGB), where δ is the GB width and DGB is GBD coefficient) was determined by the molecular dynamics method with calculation of atomic mean square displacements (MSD) at different temperatures: 825, 900, 1000 and 1200 K On Fig.2 MSD data at temperatures of computer experiment are presented.
As for comparison with other data obtained by computer simulation, the agreement is reasonable taking into account difference in potentials chosen for simulation and difference in GB structures.

Natural fibres reinforced composite structures much different and unique than the synthetic composites as they are non- uniform with irregular cross-sections [9-15] and have a wide range of application in our day-to-day life [16].
It is strong because of cortex keratin which is in the form of long chain and these chains are compressed to form a regular structure which is responsible for flexibility also [28].

Characterization and Application of Calcium Alginate/Go (Graphene Oxide) for Adsorption Na+ and Cl- Ions Khoiril Amin1,a, Alif Alfarisyi Syah1,b, Anugrah Ricky Wijaya1,c*, Surjani Wonorahardjo1,d, and Adilah Aliyatulmuna1e 1)Department of Chemistry, Faculty of Mathematics and Natural Sciences, State University of Malang, Jl.
The higher the concentration of CaCl2, the more Ca+ ions will bind to carboxylic groups and oxygen groups that can strengthen the structure of calcium alginate/GO beads and strengthen material properties so as to increase the ability to adsorb Na+ ions.
