A team of Chinese scientists have developed a large-scale transparent smart window that can change light intensity while effectively capturing the particulate matter in smog, a study said.

The study published on Saturday in the journal iScience described a simple solution-based process to fabricate large-area flexible transparent windows with Ag-nylon electrodes for high-efficiency PM2.5 capture, reports Xinhua news agency.

It takes only 20 minutes to fabricate 7.5 square metres of Ag-nylon flexible transparent windows showing an optical transmittance of over 86 per cent, according to the group of scientists led by Yu Shuhong from the University of Science and Technology of China (USTC).

The Ag-nylon mesh can not only change the indoor light intensity, but also purify indoor air as a high-efficiency PM2.5 filter.

The scientists found that the obtained Ag-nylon electrodes could be used as an ideal intelligent thermochromic smart window with excellent mechanical stability.

It remains stable after undergoing a bending test with 10,000 bending cycles with a minimum bending radius of 2.0 mm.

Also, the Ag-nylon electrodes can remove PM2.5 by 99.65 per cent while remaining stable even after 100 cycles of PM filtration and a cleaning process, according to the study.

Union Environment Minister Prakash Javadekar on Tuesday said a programme has been formulated to reduce air pollution in 102 cities across the country.

Interacting with reporters here, he said that action plan to implement “Control of Pollution” programme for 80 of these cities was ready and the ministry has earmarked Rs 460 crore for it.

“Our intention is to make the Earth green and sky blue. We have taken up 102 cities on the priority basis, where pollutants such as dust, solid waste, vehicular emmission, are causing air pollution,” he said.

Maharashtra has the highest number of cities, including Mumbai, in the list, while Delhi, Bangaluru, Bhopal, Lucknow are among the other major cities. The minister also said that the cities with million plus population would be given Rs 10 crore each under the programme.

The ministry has also come up with a list of 28 cities, where it intends to reduce Particulate Matter (PM) – PM10 and PM 2.5 – by 10 per cent in the next one-two years.

The minister also said that his ministry has received an increase of Rs 482 crore in the 2019-20 budget to Rs 3, 175 crore which was 16 per cent higher year-on-year.
