Researchers have demonstrated that ultrasmall plant-derived crystals can be developed into a super-glue, an advance that may lead to eco-friendly and cost-effective adhesives.
A single drop of the "eco" glue has enough strength to hold up to 90 kilogramme (kg) weight, but can still be easily removed by the touch of a finger, as needed.
The researchers said the new glue may increase the reusability of valuable structural and decorative elements, provide new solutions for packaging applications, and lead to the development of greener adhesive solutions.
India was the fifth most polluted country in 2019 with Ghaziabad in the National Capital Region ranking as the most polluted city in the world, according to a global compilation of PM2.5 particulate pollution data.
On the whole, air pollution in India decreased in 2019 from 2018 though about half of the 50 most polluted cities were in India.
Whilst cities in India, on average, exceed the World Health Organisation target for annual PM2.5 exposure by 500%, national air pollution decreased by 20% from 2018 to 2019, with 98% of cities experiencing improvements.
