(HBO) – A compact device priced at only 880,000 VND (38 USD) that can automatically deodorize and dehumidify enclosed spaces like shoe cases or refrigerators is the product earning Hoa Binh’s teachers and students a gold medal at the World Invention Creativity Olympic, held in the Republic of Korea last July.
The province won the gold medal right in the first time it
had sent an entry to this competition, which is a pride and a great driving
force for local teachers and students in scientific and technical creation.

The authors of the automatic deodorization and dehumidification
device for enclosed spaces that obtained a gold medal at the World Invention
Creativity Olympic 2019.
Talking about the idea of this device, Nguyen
Tuan Dung, a 12th grader at the Hoang Van Thu High School for the Gifted in Hoa
Binh city, said he and his teammates love football, but after each match, their
shoes usually have bad odour which cannot be thoroughly treated, especially
when the shoes are put in enclosed shoe cases. Therefore, they had the idea of
creating a device deodorizing and dehumidifying enclosed spaces. At first, the
device was intended to be used for only shoe cases, then it was developed to be
applied to refrigerators as well.
Dung said their project won the second prize of
the national scientific and technical creation contest 2019. With the assistant
of their teacher Pham Dinh Man, they improved their product to send it to the
international competition.
Pham Dinh Man said both teacher and students had
to experiment numerous times, which required great patience.
The most difficult thing was to find out
suitable odour detection sensors, he noted, adding that they bought many types
of sensors to test. The finished device was highly valued for several strengths
like high applicability, compactness and reasonable price.
Man said they hoped their device will be widely
used in the daily life in the coming time./.

After the historic victory on April 30, 1975, which liberated the South and reunified the country, the whole Vietnam embarked on a new mission — promoting peace and reconstructing the nation with century-defining projects. On the fierce Da River, over 30,000 engineers, sappers, and construction workers battled against rocky mountains and raging floods to achieve a remarkable feat. The Hoa Binh Hydropower Plant, the largest of its kind in Southeast Asia at that time, officially began generating electricity, lighting up the North and ushering in a new era of industrialisation.
