Compared with DAC (diamond anvil cell) static super-high pressure apparatus, the 6-8 type multianvil high pressure experimental apparatus can provide us a larger sample, which is convenient to test physical property and can be used to synthesize some new materials with special properties.
The sample pressure can be obtained through measuring the resistance changes associated with high pressure phase transition of metals, semiconductor materials.

With the benefits of positron annihilation and variable beam energy, it is a sensitive probe to detect open-volume defects in various materials such as metals, semiconductors, polymers and nanomaterials [4][5].
Slow positron beam in University of Science and Technology of China (USTC) are used in this work.
With the ability to separate information of defects in surface from inner layer as well as to provide more details about defect structures at atom level, positron beam is proved to be a powerful and sensitive tool for defects structure studies of DMS materials.

It was because of the adding of QDs improving the crystallinity of the material that the temperature of weight loss rised and heat-resistant capacity was enhanced for composite fibers.
It indicated that burned material was not QDs but the polymer.
