Prime Minister Pham Minh Chinh visits the Science and Technology Exhibition booth of VAST
With the leading position in scientific research and technological development of the whole country, at the exhibition booth, VAST introduced a number of outstanding science and technology products in fields such as space technology, biotechnology and metal spraying technology with high practical scientific application. VAST's pavilion has become a major attraction for delegates with "made in Vietnam" products.
Some outstanding products displayed at the event include:
Technology products of metal coatings of the Institute of Tropical Engineering project group by Dr. Ly Quoc Cuong presided. Metal overlay spraying technology is very suitable for the restoration of worn industrial machine parts such as: motor rotor shaft neck, compressor shaft neck, fan shaft neck; bearings such as: engine flange cover, shaft pillow; babbitt pillows (babbitt material B83- B89). Coating materials are Cr steel, CrB alloy, Cr bits, Nb bits; tungsten bits; NiCr, hardness from 38 - 67 HRC, high adhesion. This is an abrasion recovery solution that ensures quality, safety and economy, because only a small amount of material is needed to compensate for the worn part of the machine, we get an almost 100% original product. The advantages of the technology include: because thermal spraying technology uses an indirect heat source with a detailed background, it does not warp or deform the part (control the product temperature is not more than 100oC); product quality is guaranteed due to the use of spray materials with durability, as well as high hardness, good adhesion ability to the detailed base; The price is cheap because only a small amount of material can restore the worn position, giving us almost new restoration products (better surface quality than new products, because the coating materials are alloys such as Cr, CrB, NiCr).

The circular economy model from industrial waste is a technological product under the state-level project: "Research and development and application of advanced biogas technology to generate electricity and use sludge after anaerobic fermentation to produce organic fertilizer to develop clean agriculture in Dak Lak", Code: TN18/C07, implementation time 2018 – 2020 under the National Science and Technology Program in the period of 2016 – 2020: "Science and technology for socio-economic development of the Central Highlands in regional integration and international integration", by Assoc. Prof. Dr. Do Van Manh, Director of Institute of Energy and Environment Science and Technology. The model explores waste management and treatment technologies towards a circular economy and the creation of valuable products from waste. The research results obtained the criteria of greening in production, towards the goal of net zero emissions and sustainable development.

Pico Dragon satellite with dimensions of 10 x 10 x 11.35 cm, mass of 1 kg, is the first Vietnamese-built satellite to successfully operate in orbit. The satellite was developed by a team of young engineers and researchers of Vietnam National Space Center. All steps in the satellite development process from research, design, fabrication, integration to testing are carried out in Vietnam. The satellite's mission is to take pictures of the Earth, measure some satellite parameters and the space environment by satellite-mounted sensors, and test communications with the ground.
The NanoDragon satellite with dimensions of 10 x 10 x 34.05 cm, a mass of 10kg is also researched and developed by the Vietnam Space Center. The satellite is responsible for testing technology to control the direction of satellites in orbit and receive automatic identification signals using nanosatellites. This is the product of the project "Research, design, manufacture, launch and operation of nanoscale microsatellites" under the National Science and Technology Program on Space Technology in the period of 2016 – 2020.
The MicroDragon satellite has dimensions of 50 x 50 x 50 cm, mass of 50kg. This is a product in the Basic Satellite Training Component, part of the project "Disaster prevention and climate change using Earth observation satellites" (abbreviated as Vietnam National Space Center Project). The project uses preferential ODA capital from the Government of Japan, coordinated by the Japan International Cooperation Agency (JICA) and counterpart capital by the Government of Vietnam. Specifically, the basic satellite training component performs the task of "Training 36 masters of space technology and practicing the trial manufacture of one micro satellite (weight about 50kg) at some universities of Japan". The satellite was developed by 36 students who are staff of Vietnam National Space Center at five Japanese universities.
