Classify	Excellent
Goal and objectives of the project	General goal: Obtain technology to fabricate Hydroxyl Apatite (HA) surface coating solution based on TiO2 to apply kill bacteria, fungi and toxic chemicals at offices, clinics/hospitals and in households. Specific objectives: Research and complete the technology for fabricating HA surface coating solution based on TiO2 having spherical crystal is 20-30 nm in size and rod crystal is10 x10 x 20 -500 nm in size to kill bacteria, fungi and toxic chemicals (organic solvents) at workplaces, clinics/hospitals and in households. Develop products from laboratory scale to production on a larger scale of 10L/day.
Products of the project	- HA/N-TiO2 solution was delivered to the customer (150 liters) and 500gr of HA/N-TiO2 powder was used for Aldehyde testing by Kanagawa Institute of Industrial Science and Technology in Japan. - Product quality: The solution is not precipitated and has a milky white color. N-doped TiO2 has a nano size of 15-30 nm (spherical) and a rod size of 10 x 10 x 20 (up to 500 nm). With a TiO2 content of 3-5%, the HA/N-TiO2 solution costs only a quarter of its import price, but the quality is equivalent or even better. - Patents (list): - Other products (if applicable): - Register a trademark “NANOTiO2 - HHA photocatalytic coating” - Scientific articles: 02 articles - 01 Process for synthesizing HA/N-TiO2 solution on a scale of over 10L/batch. - Master's training: 02 MSc - Book: monograph "Natural and synthetic apatite applied in environmental treatment" Natural Science and Technology Publishing House, 2022. - Certificate of Merit from the Principal of the University of Natural Sciences, Vietnam National University, Hanoi for guiding students (Mai Viet Ha) in scientific research and competing for third prize in 2024, Commendation Decision No. 1203/QD-DHKHTN dated April 24 /2024.
