IIT-Madras startup creating textile with antimicrobial material to tackle coronavirus
The coated textiles can be primarily used to manufacture N95 masks, surgical masks, PPE and food packaging bags, among others, with inherent properties of inactivating the virus.
Chennai :
An Indian Institute of Technology (IIT) Madras-incubated startup Muse Wearables is developing novel and scalable methods for coating textiles with nanoparticles-based antimicrobial agents that can inactivate the human coronavirus on contact, the Institute said on Monday.
These coatings are expected to be effective up to 60 wash cycles, thereby making the textiles re-usable.
The coated textiles can be primarily used to manufacture N95 masks, surgical masks, Personal Protective Equipment (PPE) and food packaging bags, among others, with inherent properties of inactivating the virus.
According to the Institute, Muse Wearables’ current pilot machine can coat textiles of length up to 100 metres within a few minutes, thereby making it a viable commercial solution that can be deployed immediately.
Muse Wearables was incubated by IIT Madras Incubation Cell.
“They have quickly mobilised and repurposed their offerings in response to the situation and are striving to make a positive contribution to the nation’s anti-virus efforts,” Dr Tamaswati Ghosh, Chief Executive Officer, IIT Madras Incubation Cell, said in a statement.
Some highlights of these nano-particles coated textiles include, anti-microbial properties — it continuously captures and destroys viruses and other microbes upon contact. Other viruses are as small as 30 nanometres can also be inactivated permanently.
It does not leach while washing in water and is environment-friendly. At present, the particles can be coated on materials like cotton, polyester and cotton – polyester. More fabrics will be tested soon.
It is non-toxic and therefore can be safely used for making masks and other PPEs, the Insititute.
Currently, the startup is assembling the coating machine and will shortly commence coating various textiles with different nanoparticle solutions.
Their coated textiles are expected to be ready for testing by the first week of May 2020. The start-up is also partnering with a mask manufacturing company to launch five-layered Antiviral N95 Masks at an estimated price of Rs 300 per piece.

What a ‘window’ful world!
The series, titled ‘Windows of Madras’, takes us on a journey around the age-old city via its windows, giving us a peek into the history that seeps through its crevices.
Chennai :
From the stained glass windows of Santhome, unique horizontal windows of Chintadripet, sunburst jaalis of George Town to the Art Deco windows of Royapettah — the distinctive character of buildings is almost often interwoven with the area’s heritage and is reminiscent of its architectural history. In an attempt to capture the essence of Chennai’s myriad structural styles, Sunil Raghavendher, an architect, has set out on a mission to create an encyclopedia of the city’s hidden marvels through visual imagery.
The series, titled ‘Windows of Madras’, takes us on a journey around the age-old city via its windows, giving us a peek into the history that seeps through its crevices. Minimalist illustrations, geometric shapes and a blend of colours make the series an aesthetic affair. “My idea is not to just focus on the windows but to give a taste of how every component of a structure can come together and build a certain mood. This will act as a visual encyclopedia of Chennai’s architectural diversity,” he says.
The idea took form during Sunil’s 28-day self-quarantine period at his home in Mogappair. “I was working at a firm in New Delhi. When the lockdown was announced, I took the last domestic flight from New Delhi to Chennai and landed here last month. As soon as I reached Chennai, I self-quarantined. That’s when I had all the time for myself and decided to work on this series,” he says. As part of initial research, Sunil browsed through information about heritage buildings listed in Chennai Metropolitan Development Authority’s (CMDA) and Heritage Conservation Committee’s (HCC) websites. “This gave me a set of localities to concentrate on and read about. The Internet gave me enormous information about the history, cultural and architectural background of these areas,” he says.
Through the illustrations, he aims to not just express his love for the city but also hopes to create awareness on heritage conservation. “I’ve always had a sketchy idea about wanting to do something for Chennai that would matter. I wanted to focus on the architectural heritage of the city. Something that’s often been ignored,” he explains, sharing a quick trivia. “In India, Chennai has the second largest number of heritage buildings after Kolkata. Not many are aware of that. Most buildings are in a dilapidated condition and need attention. These structures, if they aren’t preserved might go down and we will be losing a lot of our own stories. So this type of archival is very important. It will make us value what we have,” he explains
He has currently completed around 18 illustrations and is working on more. “I am also focusing on areas which are seldom given importance to — in terms of heritage conservation. What we all need to be aware of is that conservation is a slow process. So apart from the involvement of government bodies and private organisations, neighbourhoods should also come together to preserve what’s in their backyard,” he says. He hopes that people become aware of the structural marvels around them the next time they step out and can observe the intricate detailing in simple facades of everyday life. “Next, I will be focusing on different types of doors — how they are reflective of a society, its socio-economic condition, religion and heritage,” he shares.

Royapettah
Royapettah consist a rich architectural and cultural diversity — from the garden houses of the close knit Anglo-Indian community to the agraharams and the Islamic style houses dating back to the Nawabs of Arcot time with predominant Christian influence. The houses of Royapettah built in 1920s and 1930s derives its idea from the Art Deco style of architecture.
Santhome: The history of Santhome is woven with its Cathedral. Santhome has old, classical buildings, some in white, faded green, grey and yellow but all them resonate with charm and warmth. The houses and street names has a Portuguese hangover. There used to be a lot of Anglo-Indian families living in European style houses which are now given away to apartments.
Mylapore: The area doesn’t just have the agraharam houses but also consist of heritage houses with Neo Classical architecture and houses with an amalgamation of Classical, Indian and Muslim style of architecture. The houses built before 1930s have wrought iron balustrades and houses from 1930s and 1940s were constructed in the Art Deco style with distinct geometry.
Mount Road: The settlements on the road are older than the road itself. The buildings on this road display a dominance of Dutch architecture, Art Deco and Indo-Saracenic style.
Chintadripet: Chintadripet was one of the few localities in those days where streets were not demarcated on the basis of caste. Chintadripet used to have many row houses back then. The walls of every house were connected to each other. These houses were reminiscent of the French Art Decor style of construction, which followed the pattern of horizontal windows and vertical doors. Many houses used to have (and some still have) the Gajalakshmi symbol on top that signifies wealth. The houses run deep inside and have two courtyards; one in the front and another at the back. These houses still have the old style of door hinges, flooring, water pumps and even rain water harvesting systems.
T Nagar: T Nagar is believed to be the first planned urban neighbourhood in Chennai created in 1920, conceived in a European style, with the Panagal Park resembling the Arc De Triomphe and the Pondy Bazaar resembling the Champs-Élysées in Paris.
Triplicane: The streets of Triplicane take one through historic Pallava settlement that have transformed through the ages while still rooted firmly in their rich and varied culture and its architectural styles and influences that range from Vernacular to Neo Classical to Art Deco.
George Town: The neighbourhood is known for several classic styles of buildings such as Indo-Saracenic, Neoclassical, Gothic, and Art Deco, apart from several traditional styles. Each building presents its uniqueness in its architectural character.

T.N. plans portal for workersabroad intending to return
An estimated 2.5 lakh workers from State are expected to return, says an expert
The State government is planning to develop a portal for Tamil Nadu natives who are employed abroad and intend to return in the wake of the COVID-19 outbreak.
“The portal should be up in the next few days,” a senior government official said. Once the COVID-19 lockdown was lifted and transportation including air traffic opened, the data from this portal could be used in allowing them to return as well as quarantine them, he said.
Kerala government has already set up a portal allowing its natives working abroad to register. “We are expecting about a lakh workers to return,” he added.
Another official said a lot depended on when and how the Centre would open up air traffic into the country.
“The subject of air traffic was discussed during the recent video conference the Prime Minister had with the Chief Ministers. So, naturally, we need to plan on how to manage the inflow of NRI workers,” he said.
Professor S. Irudaya Rajan of the Centre for Development Studies (CDS) in Thiruvananthapuram, a noted expert researching on migrants, feels an estimated 2.5 lakh Tamil workers could return from abroad. “Over 25 lakh workers from Tamil Nadu are employed in various countries and of them, I expect at least 10% of them to return this year,” he said.
Planning ahead was necessary as to who should be allowed preference since most of them would be in a rush to return. “Priority would be given naturally to pregnant women, children and elderly persons.”
According to Mr. Rajan some 12 lakh workers are employed in the Gulf countries. “Almost all the countries are affected by COVID-19 and because of the repercussions, most of them would want to or be forced to come back home, if they could not continue to work there anymore,” he said and pointed out there may not be any job for them here too at once. Tamil Nadu and Kerala had 25 lakh and 22 lakh of their people working abroad respectively, which constituted almost one-fourth of 200 lakh Indians workers employed abroad, he said.
Based on a survey of a random sample of 25,000 households across Tamil Nadu in 2015, his team of researchers have put the figure as 25 lakh.
Mr. Rajan emphasised that in many households, the family was dependent on the remittances made by their family member employed abroad and once he/she lost his/her job, the family would have to find another source of income. The State government could think about conducting medical checks for them, finding jobs for them, among others.

Villupuram college student creates ‘smart stethoscope’
The invention had won first prize at a university-level exhibition for bio-based equipment last month.
Villipuram :
A first year engineering student from Tindivanam has invented an equipment that could help the doctors in treating patients from a distance, avoiding the danger of getting infected themselves.
M Srinath invented the ‘smart stethoscope’ as part of his academic project at Mailam Engineering college.
The invention had won first prize at a university-level exhibition for bio-based equipment last month.
“With the stethoscope that I have made, doctors can check temperature and pulse of a patient from a safe distance.
The equipment is of high quality though it doesn’t cost much, and it can last for long with battery support. The patient can wear this equipment like a watch and through artificial intelligence, the required readings will appear on a device with the doctor even if the patient is 500 metres away,” Srinath told Express.
