Nature Communications Materials published the research results on aluminum alloys of Yingbo Zhang's team from School of Materials Science and Engineering at the University.

Zhang Yingbo’s team proposed an improved Efficient Global Optimization (EGO) algorithm based on Kriging model, and applied it to the composition optimization of 7xxx alloy. A 950MPa 7xxx alloy with zinc content less than 7wt.% and unusual Al8Cu4Y nanonetwork structure was found in the deformed 7xxx - T6 alloy, which may be helpful for the design of high strength aluminum alloy in the future. This research manifested the feasibility of using machine learning to find 7xxx alloy with good mechanical properties. The improved alloy through optimization will be the candidate material for mass production of key components of high-speed train. Related research results were published on Communications Materials entitled "Accelerated discovery of high strength aluminum alloys by machine learning".

In this paper, it is found that the rare earth 7xxx alloy made with traditional processing technology can have high tensile strength. In addition, this paper proved the feasibility of using machine learning to accelerate the discovery of 7xxx alloy and the potential strengthening effect of Y element. In particular, Zhang Yingbo’s team found the unusual Al8Cu4Y nanonetwork structure, which is of great value for the alloy design of high-strength aluminum alloy.

Research team from the School of Materials Science and Engineering published a series of research results in Proceedings of the Combustion Institute and Combustion and Flame, top international journals in the field of combustion

Recently, Ning Hongbo’s research team from the School of Materials Science and Engineering, published two papers in the same issue of Proceedings of the Combustion Institute, a top international journal in the field of combustion, and one briefing paper on Combustion and Flame. This is the first time for both Proceedings of the Combustion Institute and Combustion and Flame to list Southwest Jiaotong University as the authors’ first affiliation.

The International Symposium on Combustion is the largest, most influential and highest-level one in the field of combustion science and technology. It has been hailed as the "Olympics" of combustion, and is held every two years by The Combustion Institute. Proceedings of the Combustion Institute and Combustion and Flame are recognized as top journals in such fields. The latest impact factors are 5.627 and 4.57 respectively, ranking Q1 in the JCR.

Kaiqin Xiong and Zhilu Yang at the School of Materials Science and Engineering published their research papers in Bioactive Materials.

Kaiqin Xiong, engineer from the Key Laboratory of Advanced Technologies of Materials, Ministry of Education, Zhilu Yang, researcher from School of Materials Science and Engineering, and Dr. Zhou Minggang, deputy chief physician of the Department of Cardiology of the Third People's Hospital of Chengdu, recently published a paper entitled “Nitric oxide-generating compound and bio-clickable peptide mimic for synergistically tailoring surface anti-thrombogenic and anti-microbial dual-functions” with the university as the authors’ first affiliation in the international journal of Bioactive Materials (IF: 8.724).

The research results contained in the paper not only provide new solutions to surface modification of several functional molecules, but also provide new ideas for surface bionic design of extracorporeal circulation catheters, with great clinical potential.
