On the morning of July 1st, 2019, Sino-LinchemInternational, Inc. and BLACK P2 (USA) INC, a U.S. high-tech start-up company,donated 10 million yuan worth of high-end material "BLACK phosphorus"to Tianda Baojie Saida Innovation and Technology Research Institute. TheCooperation and Donation Ceremony was successfully held at the ConferenceCenter of Xiqing Economic Development Zone, Tianjin, China. Ms. Lin shan, VicePresident of our company, Ms. Liang, Deputy Chief Engineer, Mr. Li, Engineerand Mr. Alan Liang, Representative of BLACK P2 (USA) INC, attended the ceremony.

At the Donation Ceremony, Professor Wei Hongyuan,President of Tianda Baojie Saida Innovation and Technology Research Institute,introduced the achievements of the Institute in science and technologyinnovation and achievement transformation as an international innovationplatform. Ms. Lin Shan, Vice President of our company, and Ms. Liang, DeputyChief Engineer, respectively introduced our company's development status,research on key technologies of black phosphorus industrialization and its futureapplication. Ms. Lin Shan, on behalf of the company and BLACK P2 (USA) INC, aU.S. technology company, donated the first batch of "BlackPhosphorus" products to Tianda Baojie Saida Innovation and TechnologyResearch Institute.

Ms. Lin Shan said in her speech that Tianda BaojieSaida Innovation and Technology Research Institute has outstanding talents andexperienced team, has the ability of independent development and hasfirst-class and most complete R&D experimental equipment in China. On the Anniversaryof Chinese Communist Party, we donated black phosphorus crystal products toresearch and develop the application of black phosphorus, accelerated thetransformation of scientific and technological achievements of black phosphorusas a new material, actively promoted the development of black phosphorus in newmaterials industry, and accelerate the application of black phosphorus invarious fields in the future. This is a day of profound significance! We hopeto actively promote the research and development of "blackphosphorus" products and expand the application of black phosphorus in thehigh-tech field with the help of the world-class R&D platform of TiandaBaojie Saida Innovation and Technology Research Institute.

Black phosphorus, a black metallic crystal with alattice of linked six-membered rings, is the most thermodynamically stable ofthe allotrophes of phosphorus. It is well known that single-layer graphite hasdominated the two-dimensional materials world for the past decade, but due toits lack of orbital energy gap, graphene cannot be integrated as asemiconductor material with traditional silicon-based devices, which greatlylimits its application. In recent years, black phosphorus as a newtwo-dimensional material has attracted great attention from scientists. Blackphosphorus itself has an energy gap and can be used as an adjustablesemiconductor to solve the problems of graphene. It has a great applicationprospect in the next generation of nanometer electronic devices, photoelectricdevices, solar energy, biomedicine and many other cutting-edgetechnologies and industrial fields.
