Introduction
Since the 1970s, polyaniline (PAn) with good electrical conductivity properties has aroused wide research interests, and it has become a new type of functional materials with the most development prospect [1-3].
Among these polyaniline materials, polyaniline with one-dimensional tubular structure has a potential application due to its special structure which is in favor of electron transfer.
There are many preparation methods to fabricate polyaniline materials, among which the chemical oxidation polymerization [7] with simple reaction process and without any template or complex post-processing and equipment has important useful value.

Microstructure Refinement of Magnesium Based Alloy

The traditional strengthening principles, such as solid solution strengthening, precipitation hardening and work hardening, are not very effective in improving mechanical properties of magnesium based alloys since the techniques related with above principles are deleterious to the ductility of metallic materials.
However, Mg-Al based alloys, such as AZ91, AZ31 and AM60, are most important magnesium alloys and are used in approximately 90% of all magnesium products as structural materials at present.
