On October 24, 2018, professor yu wei, professor wang lingling and some graduate students from the ministry of engineering participated in the ninth China international nanotechnology industry expo (hereinafter referred to as "China nano expo"), which was opened at suzhou international expo center in suzhou industrial park. The conference attracted more than 1,000 nanotechnology enterprises and institutions from 25 countries and regions to participate in the exhibition, and over 1,300 innovative products of nanotechnology were exhibited.

 The expo will continue to focus on nano new materials, micro nano manufacturing, energy and clean technology, nano biotechnology and other industrial fields. There will be a main report and 12 professional conferences with distinct themes, including the industrialization of nano energy materials BBS, advanced materials and manufacturing high-end BBS in China and Australia. The expo also specially organized two international meetings between China, Iran and the Netherlands to build a platform for international exchanges and cooperation. With the expansion of naxo expo''s influence, nanotech companies and institutions from 25 countries and regions will participate in naxo expo this year, for example, Nikon in Japan, SUSS in Germany, SAWATEC in Switzerland, leuven in Belgium, Gigalane in South Korea, and INL in Europe. Countries such as Canada, Iran and Japan will also participate in naxo expo in groups. At the same time, the nano-smart life museum also made its debut, gathering more than 100 nano-smart products, such as nano-floor heating, large-size capacitive touch screen, dimming glass, nano-environmental protection coating and so on. Taking part in this grand meeting brings the most preface scientific and technological knowledge to teachers and graduate students, broadens their horizon, and injects strong impetus into future scientific research work.
