Recently, the Fifth International Conference on Nanoenergy and Nanosystems was held in Beijing. Hosted by the Beijing Institute of Nanoenergy and Systems of the Chinese Academy of Sciences, experts and scholars from related research fields at home and abroad gathered together to discuss major frontier issues in the field of nanoenergy and systems.
Energy is the fundamental driving force for the progress of human civilization and the decisive factor in global technological change. Nowadays, human society has begun to enter the era of big data, artificial intelligence and the Internet of Things, in addition to the traditional "big energy" such as electric energy and fossil energy, human beings have begun to explore "small energy" such as micro-nano energy to solve the problem of self-supply of small devices in the era of the Internet of Things.
In 2012, Chinese scientists took the lead in developing friction nanogenerators, which can collect low-frequency mechanical energy scattered in the environment and convert it into electrical energy. Over the years, China has made a series of important progress in theoretical research such as piezoelectric electronics and piezoelectric optoelectronics, as well as the development of application technologies such as friction nanogenerators and micro-nano sensors.
Gao Hongjun, academician of the Chinese Academy of Sciences and vice president of the Chinese Academy of Sciences, said in his speech that the marine blue energy technology with nano-generators as the core can efficiently collect marine wave energy and convert it into electricity, providing a possibility for human beings to use marine energy on a large scale, and providing an exciting energy technology path for the world to achieve the great goal of "carbon peaking and carbon neutrality".
Gao Hongjun pointed out that China is one of the major countries in the world's nanotechnology research, after more than 30 years of development, the overall strength of China's nanotechnology research has been at the forefront of the world, and China's nanotechnology research is facing new major development opportunities. In the next step, we will take micro-nano energy and micro-nano systems as one of the key research and development areas of nanotechnology, strive to develop more innovative achievements, cultivate more scientific research talents, and make greater contributions to the world's nanotechnology and energy research.
Gao Ruiping, deputy director of the National Natural Science Foundation of China, also said that energy has become one of the most concerned areas for the development of various countries, especially under the "double carbon" goal. The energy problem of sensors needs to be solved urgently, and how to obtain energy from the environment to drive these sensors with small but huge numbers, extremely wide distribution and movement is still a huge challenge. The National Natural Science Foundation of China will support basic research and scientific frontier exploration, support talent and team building, enhance the ability of source innovation, and provide knowledge reserves for high-level scientific and technological self-reliance and self-reliance.
After the opening ceremony, Sun Licheng, a foreign academician of the Chinese Academy of Sciences and professor of Westlake University, and Bao Zhenan, academician of the National Academy of Engineering and professor of Stanford University, were invited to give a conference report.
A total of 7 sub-themes will be set up to focus on the latest research results in the field of nanoenergy and systems. The conference also selected scientists who have made outstanding contributions to nanoenergy and nanosystems and awarded the "Nano energy award", which was awarded by Professor Zhang Haixia of Peking University, Professor Zi Yunlong of the University of Chinese of Hong Kong, and Yang Ya, researcher of beijing Institute of Nanoenergy and Systems, Chinese Academy of Sciences.
