    Abstract: It is a relatively easy task to the solution of the so-called phase problem in crystallography, by applying ab initio phasing methods for the efficiency of structure solution from single-crystal data. Their effective application to powder x-ray diffraction data is still a real challenge unless the size of the structure is moderate. The percentage o... Show More

    Abstract: With the development of biological tissue engineering, vascular stent materials have been greatly improved. Synthetic polyester polymers and bio-derived materials with excellent biocompatibility, biodegradability and mechanical strength have greatly improved. These are ideal tissue vascular scaffold materials. Vascular stents mainly play two roles ... Show More
