., specific surface area, pore size distribution and surface chemistry, were studied.
The surface organic structures of the bamboo and the activated carbons were studied by Fourier transformed infra-red spectroscopy (470FT-IR, Nicolet Nexus).
In accordance to the classification adopted by the International Union of Pure and Applied Chemistry (IUPAC), pores are classified as micropores (<2nm diameter), mesopores (2-50 nm diameter) and macropores (>50 nm diameter) [16].
These results are in agreement with the surface chemistry of other agricultural by-products such as peach stones and rockroses.

Abstract.
Single phase anatase structure was obtained after calcination at 400 °C.
Multi-phase of anatase and rutile structure was obtained after calcined at 600 and 800 °C.
In the Analytical Chemistry Laboratories it is mainly used as an acid base indicator due to its ability to function as weak acid as the aqueous solution of the dye has a pH value of approximately 6.5 (5 g.L -1, H2O, 20 ◦C) [7].
Confirmation structure of TiO2 powder was obtained by comparison with the Joint Committee on Powder Diffraction Standards (JCPDS) Card File No.21-1272 [11] and 21-1276 [12].

The control of the interfacial chemistry between a high-k dielectric and III-V materials presents a formidable challenge compared to that surmounted by Si-based technologies.
InP is under consideration for quantum well channel MOS structures in order to serve as a better nMOS channel interface.
Substrates are then analyzed for an assessment of the initial surface chemistry present typically by XPS and electron diffraction (for long range structural order assessment).
The apparatus design enables the study of the effect of single precursor exposures on the surface (viz., half-cycle studies) and thus the resultant interfacial chemistry during film growth, which can be correlated to device behavior. [5] III-Arsenides As noted in a recent review, [5] InxGa1-xAs are now among the most studied interfaces with high-k dielectrics.
