I. Introduction 
Tianjin University, Tianjin nanoparticles and nano-Systems International Research Center (referred to as “nano-Center”), was in March 2016 by the Tianjin University of the 46th Standing Committee approved the construction of the immediate Scientific research unit. It will be fully operational on July 22, 2018. As a new international research institution, the Nano Center has received care and support from leaders and colleagues at all levels of Tianjin University. The center has successively been approved by the National Natural Science Foundation of China, the National Natural Science Foundation of China, the National Natural Science Foundation of China, the Tianjin Natural Science Foundation of the key project, the Tianjin Natural Science Foundation of the Youth Project, and the China Postdoctoral Science Foundation (including our school’s only first-class postdoctoral fellow in 2017) National Science Foundation) and the China-US International Cooperation Fund. In 2019, the Nano Center and Akashi Innovation Industry Technology Research Institute jointly established the “Tianjin University  Akashi Zhiyuan Graphene (Nano) Materials Joint Laboratory”, which was supported by a number of projects from Akashi Innovation Technology Group. In the same year, it established a joint laboratory with Beijing 718 and obtained stable enterprise research funding. In addition, many companies such as 2018 Technology, South Korea Park Group, Cosmos Hitachi High-Tech, Tesken China, Su Daweige, Zhuo Li Hanguang and many other companies have continued to support students in the center. 
From its official listing to the present, the Nano Center has grown into a fully functional and well-equipped international research center. At present, there are 40 doctoral and master students in the center, and 3 postdoctoral fellows in the station, all of whom are selected for the “Postdoctoral International Exchange Program Introduction Project”, each of which has received a two-year national postdoctoral research grant of 400,000 yuan. While reserving excellent teachers for the school and saving the cost of human resources, it also provides important experience for the school’s postdoctoral reform. In addition, the Nano Center has just introduced a full-time American professor. The scientific research work of the center is also being carried out in a comprehensive and orderly manner. At present, more than 40 papers have been published (statistics as of 2019), including 30 SCI articles (23 publications in the second district and above), 5 conference papers, 5 EI articles, including 3 Phys. Rev. Lett., Nat . Nanotech. 1 article, Nano lett. 1 article, Nat. Comm. 1 article. 
1.1 Goal and mission
To build a world-class international research platform in the fields of graphene electronics and cluster physics, to cultivate for the motherland research talents who are determined to forge ahead and have the spirit of scientific research and innovation, aim at the frontiers of world science, serve the country’s major technological needs, and strive for success. World-class research results. 
1.2 research 
(1) epitaxial graphene electronics: SiC single crystal from optics to electronics – Preparation and Epitaxial graphene device 
epitaxial graphene graphene is an ultra high purity, which is in the induction heating furnace The silicon carbide single crystal grows on the surface of silicon carbide after being heated to a high temperature. Epitaxial graphene nanoelectronics can make full use of the volatility of electrons, so it is very likely to become an ideal material for future quantum computing hardware manufacturing. At the same time, epitaxial graphene electronic devices also have much lower power consumption than traditional silicon electronic devices, and significantly increased operating speed. One of the most noticeable features of the industry is that epitaxial graphene nanoelectronic devices can be directly put into production after a slight improvement on the basis of traditional device processes, without the need to develop new preparation processes. Therefore, epitaxial graphene nanoelectronic devices have great practical value and promotion potential. At present, Nano Center has realized the process flow of cutting, grinding and polishing, hydrogen etching from silicon carbide crystal pillars to 300 micron wafers, and has carried out the preparation and characterization of epitaxial graphene electronic devices. 
(2) Physical Cluster: spectrometer means completely independent research to build large 
clusters or several tens of micro-aggregate of atoms, typically less than 5 nanometers in size. The research work of the Nano Center based on free clusters is based on exploring its unique electrical, magnetic, catalysis and other properties as the starting point, and the final goal is to serve the development of advanced electronic equipment and new catalytic hydrolysis devices with related research results. Unfolded.
In order to study the electronic structure of free clusters, the lifetime of high excited states and the electronic structure of the inner shell in depth and systematically, we independently designed and built three sets of free cluster research systems and a set of supporting clusters research and study with two-dimensional materials Combined EPI system. What is proud of is that the above four research systems are all independently developed and designed by the center, produced and processed in China, and completely installed, debugged and operated by the teachers and students of the center. Among them, the design concept of a photoelectron spectrometer system based on a small electrostatic ion storage ring for high-resolution full spectrum measurement was first proposed in September 2015 by the executive director of the center, Professor Ma Lei. The completion of this system marks the birth of the world’s first storage ring system for full-spectrum photoelectron spectroscopy of free clusters. At the same time, this system is my country’s first storage ring system with completely independent intellectual property rights. Its process level and resolution will surpass similar large-scale equipment in Europe, filling the gap in the country’s completely independent research and development and construction of large-scale instruments in this field. 
(3) Development and research of 
flexible electronic devices based on micro-nano processing technology. Flexible electronic devices are used in the fields of biomedical engineering, new energy, environment, information, national defense, etc., with their unique flexibility and ductility, as well as electrical functions. It has a wide range of application prospects. Based on this, the center uses micro-nano processing technology to prepare one-dimensional nano silver wires, two-dimensional graphene nanosheets and other metal polymer functional composite materials, which are used in flexible electronic devices, energy storage devices, and gas sensors. This direction has become a research hotspot and key content in interdisciplinary research. At present, several million yuan has been spent on horizontal projects that have been cooperated in this direction. 
1.3 Experimental platform The 
Nano Center is diligent and thrifty, and every second counts. It successfully completed the construction target within the budget and planned time. Adhering to the construction concept of building the most advanced modern laboratory, the Nano Center is function-oriented and integrates functional design with practical beauty. Reasonable use of funds and scientific program design allow the scientific research and working environment of the Nano Center to reach international standards at low operating costs. Nano Center pays attention to energy conservation and environmental protection during the construction process, using high-end dust-proof paint, anti-static floor, LED lighting and double-layer fireproof glass to achieve safety and energy saving.
