Water and electricity shortages are serious issues facing the world at present. Hong Weisong, a professor at the Institute of Applied Science and Technology of National Taiwan University of Science and Technology, won the 2022 R&D 100 Awards for "graphene that can simultaneously produce water and electricity". Winning 12 awards, National Taiwan University of Science and Technology is the only award-winning Taiwan tertiary institution.
Hong Weisong said that the award-winning "black magic carpet that can be used to produce water and electricity at the same time". The black magic carpet refers to the graphene slurry that is evenly flattened and dried to become a black film with metallic luster. Using the graphene solar evaporator, the thin film is used as a wave power generation device, which can generate all-weather energy. While being used for ocean wave power generation, it can also convert seawater into safe drinking water that meets the World Health Organization standard.
Hong Weisong said that the graphene film can be used for both solar distillation water production and wave power generation, and it can also be easily scaled up. It can not only take into account renewable energy, but also continuously obtain safe drinking water. It can solve the shortage of water and electricity at one time. The problem.
The team of Professor Hong Weisong from the Institute of Applied Science and Technology of National Taiwan University of Science and Technology has professional capabilities in measurement, material preparation, and control technology. Among them, the measurement technology is familiar with various sensors and characteristics, mainly using piezoelectric thin film sensors, and also cooperates with the industry. The research fields include four major fields: circulating water resources, gas separation, biomedical materials and energy materials. These thin film technologies are all in line with the government's key goal of promoting net zero emissions by 2050.
Hong Weisong explained that the difficulty of graphene technology lies in how to adjust, uniformly disperse and coat technology. Only when these can be done well will the power generation efficiency be good. The products developed by the team have good performance in the piezoelectric field, and the positive piezoelectric coefficient is comparable to that of commercially available films. The same, but the inverse piezoelectric coefficient is 6 times higher than that of the piezoelectric film on the market. It is feasible to apply it in both sensors and actuators. The team's graphene coating technology has also been awarded the Oxford University Technology Innovation Platform Help with promotion.
The R&D 100 Awards are known as the Oscars in the research and development industry. This year, it will be the 60th. It recognizes new commercial products, technologies, and sciences with technical significance. It has long been valued by academics and industries in telecommunications, physics, manufacturing, and biotechnology. , is well-known in the technology circle, and the representative innovation technology of the year is regularly selected every year.
The famous annual technologies of the Global Top 100 Technology R&D Awards include halogen lamps, LCD screens, anticancer drugs, high-definition televisions, nuclear magnetic resonance imaging, nuclear fusion experiments, etc., which have been selected and widely used today. Taiwan has won 12 awards this year, second only to the United States, ranking second in the world and first in Asia. Taiwan's award-winning units include the Industrial Technology Research Institute, the Institute of Information Policy, the Metal Center, the Institute of Textiles, and the Institute of Nuclear Energy. These important legal person research units. The world-renowned award-winning institutions include MIT, Dow Chemical, DuPont, Siemens, etc.
