Professor Gu Gang's original research achievements have been well received internationally, including: (1) systematic study on the linear and nonlinear optical properties of fullerenes; (2) High-yield vapor-phase synthesis of single-walled carbon nanotubes. This is the first time in the world that hydrogen plays an important role in the gas phase synthesis of carbon nanotubes. A new method for synthesizing nanocatalysts was discovered, and the patent application based on this method was authorized by the US Patent Office (US Patent 7,235, 159). (3) Chemical sensor based on the change of electrode work function of nano-devices. The concept of measuring gas and biomolecules by using the change of work function of nano-device electrode is put forward for the first time in the world, and it has been confirmed by experiments. The patent application based on this concept has been authorized by the United States Patent Office (U.S. Pat. No.7,052,588); (4) V2O5 nanofiber driver was discovered for the first time in the world. The research results were published in Nature Materials. In the same issue of Nature and Materials, an article devoted to this innovation was published. This paper is widely quoted by scientists all over the world.
The main research achievements made by Professor Gu Gang in the R&D department of MSA (a leading multinational company in the field of mine safety appliance sensors and safety instruments) are as follows: (1) Organizing a team composed of junior scientists, testers, technicians and operators to optimize the film synthesis process and technology, and producing high-quality film gas sensors and entering the market; (2) The anti-poisoning performance of catalytic combustion gas sensor is improved by using new Al2O3; (MEMS technology reduces the power consumption of gas sensors; (4) NH3 gas sensor with high selectivity was prepared. (5) It is the first attempt to realize the industrialization of gas sensors with WO3 new materials.
