In these conditions, the chemistry and physics of the process involved in the growth mechanism of silicon thin films produced by the hot wire or the hot-wire plasma assisted technique can be proper derived by balance equations that supply information about how the plasma density, the gas dilution and the gas temperature influence the growth mechanism and the equilibrium of the concentration of species presented on the growth surface.
Introduction The actual state of know-how of amorphous and microcrystalline silicon thin films (a/µc-Si:H) grown by Plasma Enhanced Chemical Vapour deposition was accomplished by an extensive gas phase analysis performed during the deposition process, aiming to identify the main precursors of the growth mechanism and the role of the plasma on the set of chemistry reactions that take place on the growth surface.
Similar approach has also been followed, concerning the films produced by hot-wire CVD, since it may involve different gas phase chemistry [3].
The filament and the plasma sheet are the initiators of the reaction chemistry (SiH4 and H2 cracking and dissociation).
By doing so the growth surface relaxes and the structure stabilises. 1700 1800 1900 2000 2100 0.5 1.0 1.5 2.0 2.5 a) Si SiH SiH2 SiH3 R Tf (ºC) 0 20 40 60 80 100 120 140 160 180 0.5 1.0 1.5 2.0 2.5 b) Tf=1900ºC Si SiH SiH2 SiH3 R P (W) 1700 1800 1900 2000 2100 0.5 1.0 1.5 2.0 c) Tf=1900ºC H1 H2 H3 R Tf (ºC) 0 20 40 60 80 100 120 140 160 180 0.5 1.0 1.5 2.0 d) H1 H2 H3 R P (W) Figure 3 - R dependence on Tf and P for SiHx (a and b) and Hx (c and d) species formed.

Synthesis of a schiff base derived from p-hydroxybenzaldehyde and p-aminobenzoic acid had been achieved by solvent-free reaction using improved jet milling, and the structure of the compound have been characterized by Fourier transform infrared spectrometer, 1H nuclear magnetic resonance techniques and mass spectrometry.
Introduction With the increasing public attention to energy problems and environmental pollution, the research of green chemistry has gained considerable momentum in recent years 1-4.
Therefore, this method is used widely as a green chemistry method.
An important goal of green chemistry is to develop high yield reactions that do not require workup for removal of catalysts, supports, solvents or other auxiliaries 6 .
Schiff base attracted great and growing interest in biology and chemistry for many years due to their facile synthesis and wide applications 7-9.

The highest efficiency achieved for meso D-π-A structure is up to 12% [2] and 7.1% for β π-A structure [3], in which D represents the electron donor, A represents the electron acceptor and π represents a π-conjugation bridge serving as a spacer between the porphyrin and donor/acceptor.
To improve the performance of solar cells, further optimization of the structures of dyes as well as testing conditions is under investigation in our laboratory.

Structures of the chiral io-nic liquids have been characterized by the infrared spectroscopy, nuclear magnetic resonancespectroscopy and quantum chemical structure optimization method.
Molecular Structure's Computer Optimization of Chiral Ionic Liquids.
Using the method of DFT quantum chemistry (Density Functional Theory, DFT) B3PW91/6-311G (d, p) to optimize the chiral ionic liquids’ molecule geometrical structure.
The synthesis of three chiral ionic liquids have the same cation structure, so difference is that the anion.
In the molecular structure optimization, we found three types of anions in the order：PF6->BF4->Br-.

Therefore, high temperature expanding process changes tubular structure, not composition of carbon nanotubes.
