Research Directions Introduction
MSE at TJU is oriented toward the international frontier of science and the demands of the national strategic program. Fully utilizing the advantages of comprehensive material disciplines, MSE at TJU aims at creating an innovative platform for interdisciplinary emergence, encouraging the original and innovative fundamental research, actively promoting the progress of research on application and technique to meet the national major demands, utilizing the first-class research to achieve the first-class personnel training, and devoted to developing into the top Chinese material discipline having an international reputation. After years of development, MSE at TJU has defined the following advantageous and unique research directions:
(1) Manufacturing, Processing and Reliability Evaluation of Advanced Metallic Materials (MPREAMM)
Focusing on the requirements in national major engineering such as ocean engineering, aerospace and nuclear power, the projects “high-temperature structure integrity and life assessment technology and its application on key equipment in supercritical power plants” and “key technology development industrialization for P91 pipe used in high pressure boiler” both won the first prize of Tianjin award for progress in science and technology. MPREAMM established a joint laboratory for electronic packaging technology with Virginia Tech University and leads one 863 funded key project, which occupies the domestic leading level in the field of semiconductor high density packaging technology. Professor Ping Shan won “The Lifetime Achievement Award of China Welding” in 2015, which is the highest honor of the domestic welding academia.

(2) New Energy and Environment Materials (NEEM)
Based on the TJU-NIMS international joint research center, NEEM investigates novel energy and environmental materials. Remarkable achievements have been made in the fields of efficient conversion and application of solar energy as well as the new energy and environment materials and devices, of which a number of high-quality papers have been published in the top scientific journals such as Chem Soc Rev, JACS, Adv Mater, Angew Chem Int Ed, Nature Communications and ACS Nano. Funded by the 973 project, original results about artificial photosynthesis for fuel production have been obtained and the energy efficiency of photocatalytic CO2 reduction has been successfully increased up to 3.1%. Moreover, creative achievements have also been made in the fundamental study on controllable synthesis of nanostructures and devices by long-pulse laser.

(3) Advanced Ceramics and Machining Technology (ACMT)
To meet the major demands of the aerospace industry, ACMT performs research on high-performance ceramics and sophisticated machining technology. The line-envelop convex surface modeling technology of variable positioning point makes a breakthrough in the traditional processing methods for the complex molded surface of ceramics and has been successfully applied in the fine processing of ***** radome, which solved the key technical problem in the proposal of one key model radome. The thermal insulation components like mullite fibrous ceramics, high-temperature sealing components and binder, and thermal-stability emission coating have passed the quality examination and been applied in practical military products, which breaks the blockade on the technique. The high Q value and high precision microwave dielectric ceramics for phase shifter has been applied in phased-array radar. The PZT ternary piezoelectric ceramics with high d33 and high temperature stability employed to produce piezoelectric laser gyro for precision guidance has became the key component in the national key military project. More than two million of the aforementioned ceramic products have been supplied already.

(4) Composite and Functional Materials (CFM)
Based on the Tianjin key laboratory of composite and functional materials, the investigations on metal composite materials, carbon materials, biomaterials and high performance polymer materials are highly recognized. CFM is the first to propose the novel in-situ technique of synthesizing one-dimensional carbon nanotube, second-dimensional carbon nanosheet and three-dimensional carbon network in metal composite and energy storage materials, about which four published papers are highly cited. The biomaterials team has invented a completely new method to design high-strength thermoplastic/self-healing supramolecular polymer hydrogels, and developed novel technologies to produce safe, efficient, gene/drug delivery and nanotheranostic systems. A series of carbon-based composites have been designed and fabricated, which include high-energy, long-term solar thermal storage and controllable release of azobenzene-graphene hybrid, high-strength and high thermal-conductive fiber/graphite composite with hierarchical ordered microstructures and high-energy and power density fluorinated graphene anode material, providing the crucial materials for the new heat insulation system in the national aerospace project and high-energy batteries for returnable satellite in China’s lunar exploration project.
Composite and Functional Materials
