The products honored on May 17 demonstrate novelty and creativity, with potential for practical application contributing to economic efficiency.
After more than 3 months of competition, the 2023 Science Initiative Contest has found the winners of the awards. The first prize is worth 70 million VND, the second prize is 50 million VND, the third prize is 30 million VND and 2 consolation prizes, each worth 20 million VND. In the "Innovation Prize" category, products and special initiatives serving people in remote, mountainous areas are worth 30 million VND. This year, the jury and the Organizing Committee did not award the special prize of 100 million VND because there were no outstanding initiatives that met the set criteria.

1. New TIR lens for LED lights
The work was honored with the First Prize worth 70 million VND and belonged to the author, Dr. Nguyen Doan Quoc Anh and his colleagues from the Power System Optimization (PSO) research group, Faculty of Electrical and Electronics Engineering, Ton Duc Thang University.
The new TIR lens technology is a total internal reflection lens (also known as a reflector) attached to the LED lamp to help direct all emitted light forward and distribute the light more evenly. The new TIR lens technology helps reduce costs, increase efficiency and uniformity of light emission, thereby improving the quality and application of LED lamps. The research team also optimized the technology to be applied to many different LED products, used in the fields of civil lighting and industry, agriculture and fisheries. The new TIR lens initiative also received a USPTO (USA) Patent in 2022.
2. Personalized surgical guidance device in total knee replacement surgery
The research of Dr. Pham Trung Hieu and his colleagues at the VinUni 3D Lab group, Center for 3D Technology Research in Medicine, VinUni University, was awarded the Second Prize, worth 50 million VND.
Personalized surgical guidance (PSI) can guide the surgical position of joint replacement with up to 98% accuracy. Surgeons will rely on PSI to perform bone cuts during surgery according to the programming plan, helping to increase the accuracy of the artificial joint placement position to optimize the effectiveness and safety of surgery for patients. In Vietnam, there has never been any research on the application of PSI in joint replacement surgery.
The team has successfully performed nearly 50 total knee replacements as well as 40 hip replacements and hundreds of other joint replacements and bone alignments using 3D printing technology for personalized surgical guidance devices at the Vinmec healthcare system. In addition to products applying 3D technology in orthopedic trauma (PSI, patient's bone and joint anatomy model), this technology is currently also applied to other products in the field of creating nose molds for children with cleft palate, anatomical models to help personalize interventional stents for complex cardiovascular diseases or 3D titanium patch molds for skull bone defects.
3. Process of producing pre-germinated seeds
The project by author Luong Van Truong (Nam Dinh) received the third prize, worth 30 million VND. The solution provides a technical process to put germinated rice seeds into a dormant state to maintain life when facing adverse conditions (such as drought). Based on the natural physiological cycle of the plant, the seeds are then stored until the appropriate time for planting when conditions are favorable.
Seeds treated with this solution will germinate very quickly, usually within 30 to 120 minutes under suitable conditions. The innovation is applied in the production of seeds, rice and germinated cereals, raw materials for extracting active ingredients for medical purposes or functional foods (gaba, inositol, catalase). The author registered the solution for patent protection in 2021.
4. Tire rescue vehicle and spare tire replacement
The invention of author Dao Van Minh (Long Bien, Hanoi) received a consolation prize of 20 million VND. The product has a compact design that helps the tire rescue vehicle quickly and replace spare tires quickly and easily. With an alloy steel structure, special tire materials help the vehicle withstand heavy loads, helping the vehicle move easily after a few minutes when the vehicle has a problem. The author hopes to provide practical support for car users, contributing to reducing traffic accidents, congestion and reducing costs, saving time compared to calling for help.
5. Plant protection spraying equipment using mobile cable system
The project of Dinh Van Trung, a 12th grade student at Dien Chau 2 School, Nghe An, received a consolation prize of 20 million VND. This is a mobile cable spraying device to protect human health and serve the development of agriculture and industry. The model product was installed right in his yard with a complete cable, spraying arm, water line connection, and engine.
6. Producing silk fibers from snake plant leaves to make wigs and some environmentally friendly handicraft products to replace synthetic nylon fibers
The "Initiative Award" was given to Tran Thi Quynh (18 years old), Muong Nhe High School, Muong Nhe District, Dien Bien Province. The category honors special products and initiatives serving people in remote, mountainous areas, worth 30 million VND.
The group has taken advantage of wild tiger tongue plants growing in villages in Muong Nhe district to create non-shrinking, non-pilling, durable silk threads for use in wigs. The silk threads can also be used to make makeup brushes, ropes, and weaving baskets and nets. The silk threads are produced by hand, without the use of chemicals, and are expected to help people have new crops that bring economic efficiency, contributing to hunger eradication and poverty reduction.
In its second year, VnExpress's 2023 Science Initiative Contest hopes to create a playground for those who love science and technology; targeting professional and non-professional scientists under 40 years old, to seek initiatives, solutions, and connections to accelerate the application of advances in science and technology.
The entire prize money is sponsored by the Hope Foundation. This is a non-profit social and charitable fund operating for the community, operated by VnExpress Newspaper and FPT Corporation. The fund pursues two goals: supporting difficult circumstances and creating development motivation. One of the fund's activities is to promote the application of technology, equipping individuals and communities with sustainable development tools, especially equipping knowledge through education.
