Plastic bag making process

Residing in Phia Thap Hamlet at the foot of Pha Hung mountain, the Nung ethnic minority people are renowned for producing agarwood incense sticks. For several hundreds of years, members of the Nung ethnic group follow their traditional craft of making incense sticks from agarwood trees. Their incense sticks are made of natural materials, with artificial chemicals free. Each piece is soaked four times in a flour mixture of sawdust and agarwood powder in order to create beautiful incense sticks. Producing these items requires great skills, including eye movement, from makers. Generations of the Nung community have passed the tradition down to younger members. The craft is closely associated with the Vietnamese custom of burning incense on the first or 30th days of every lunar month and other special occasions, such as the ancestors’ death anniversary. The most time-consuming stage of the process is drying the incense. Locals often dry them … [Read more...] about Incense-making craft of Nung ethnic group in Cao Bang

Hanoi (VNS/VNA) - A group of Vietnamese researchers at the University of Connecticut in the US have invented COVID-19 high-tech biological face masks and patches to deliver vaccines into the human body easily. Award winning Nguyen Duc Thanh, 37, and his research team, Nguyen Lab, used autolytic piezoelectric polymer sheets, which has been studied by themselves and applied in organ transplantation since 2018, to make a special type of face mask. The invention was launched to meet the urgent need in the US last year. Most medical masks are made of synthetic polymers similar to plastic bags which are unable to self dispose and pose a major hazard to the environment. Medical masks are unable to prevent bacteria, viruses and fine dust like KN95 or N95 masks. Meanwhile, N95 masks are very expensive and can be used only one time, Dr Thanh said. Thanh’s team came up with the idea of using the autolytic piezoelectric polymer sheets that can filter the dust as effectively as N95 but … [Read more...] about Vietnamese researchers invent COVID-19 vaccine patches, reusable face masks
