.% oxygen and has no direct connection between carbon and carbon bonds in its molecular structure and higher latent heats of vaporization, which are good for solving the problem of NOx and particulate matter emissions in diesel engine.
In addition, alcohol ethers molecules vaporize quickly under high temperature inner cylinder, which changes instantaneously the molecule structure of fuel droplet sprayed from injector to extremely small oil mist.

Abstract.
The rapidly quenched Ti-15wt%Mo alloy was reported to have a fine-grained bcc structure with a lower modulus, 78 GPa with excellent corrosion resistance [6].
Change of crystal structure from a' to a² which was caused by the addition of 1.0 Fe in Ti-2.0Mo suppressed the increase of hardness in the alloy.

ABSTRACT
Perovskite-type oxide of LaTi0.5Mg0.5O3 composition was synthesized from constituent
oxide precursors by mechanochemical activation method in a high power planetary ball-mill,
followed by thermal treatment of the product in air.
INTRODUCTION Oxides with perovskite structure (ABO3) containing transition metal ions have attracted considerable interest due to their activity and stability during complete oxidation of hydrocarbons.
The A site cation, especially when it is partially substituted for another cation of different valent state, can create vacancies in the crystal structure and stabilize unusual valent states of B site cation, leading to different catalytic performances [3,4].

Previous research, carried out in 1991, showed the high similarity in primary structure of protein enterobactin synthase subunit F with the 4-CBA:CoA ligase.
Protein enterobactin synthase subunit F has unknown action, but based on the high similarity in primary structure, it could be suggested that those two proteins carry out similar function in metabolism of 4-CBA (4-chlorobenzoate) [13].

The structure of the fibers was analysised by a Nexus 670 Fourier Transform Infrared (FTIR) spectroscopy.
Obviously, the strongest diffraction peak from the PAN fiber occurs at around 2θ=17.11° in Fig 4a, which can be indexed to the (100) plane of a hexagonal structure[ 14].The broad diffraction peaks centered at 25.1° indicate that the crystallization of the pure PAN fibers is amorphous phase.
