Melbourne: A team of Indian research scientists are working on a device that can manipulate the extent of light and filter specific colors while still being transparent which can make up to “smart” contact lenses.

This research is being carried out by the scientists at Melbourne-based RMIT University and the University of Adelaide who are creating a stretchable nano-scale device to manipulate light.

These devices are made on a rubber like material which are used for contact lenses, said an associate professor Madhu Bhaskaran from RMIT.

“We embedded precisely-controlled crystals of titanium oxide – a material that is usually found in sunscreen, in these soft and pliable materials,” she said.

These materials form an ideal platform for wearable optical devices as these prove to be bio-compatible.

“By engineering the shape of these common materials, we can create a device that changes properties when stretched. This modifies the way the light interacts with and travels through the device, which holds promise of making smart contact lenses and stretchable colour changing surfaces,” Bhaskaran explained.

Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision.

In a more advanced version, the lenses can transmit data and gather live vital information or even show information like a head-up display.

“Manipulation of light using these artificial crystals uses precise engineering. With advanced techniques, we can dynamically control their filter properties, which allow us to create devices for high data-rate optical communication or smart contact lenses,” explained Dr Withawat Withayachumnankul from the University of Adelaide.

The current challenge is that dielectric resonators only work for specific colours, but with the new flexible surface, scientists can adjust the operation range simply by stretching it.

“With this technology, we now have the ability to develop light weight wearable optical components which also allow for the creation of futuristic devices like flexible smartphone cameras,” noted Gutruf in a paper published in the journal ACS Nano.(IANS)(image-fitnesskites.com)

June 17, 2018:

Restaurateurs Prodyut and Sumana Mukherjee have not only brought Indian cuisine to the ongoing FIFA World Cup 2018 here but also plan to dish out free dinner to countrymen if Argentina wins the trophy on July 15.

Based in Moscow for the last 27 years, Prodyut and Sumana run two Indian eateries, “Talk Of The Town” and “Fusion Plaza”.

Both restaurants serve popular Indian dishes like butter chicken, kebabs and a varied vegetarian spread.

During the ongoing FIFA World Cup 2018, there will be 25 per cent discount for those who will possess a Fan ID (required to watch World Cup games).

There will also be gifts and contests on offers during matches in both the restaurants to celebrate the event.

The Mukherjees, hailing from Kolkata, are die-hard fans of Argentina. Despite Albiceleste drawing 1-1 with Iceland in their group opener with Lionel Messi failing to sparkle, they believe Jorge Sampaoli’s team can go the distance.

“I am an Argentina fan. I have booked tickets for a quarterfinal match, a semifinal and of course the final. If Argentina goes on to lift

“We have been waiting for this World Cup. Indians come in large numbers during the World Cup and we wanted these eateries to be a melting point,” he added.

According to Cutting Edge Events, FIFA’s official sales agency in India for the 2018 World Cup, India is amongst the top 10 countries in terms of number of match tickets bought.

Prodyut came to Moscow to study engineering and later started working for a pharmaceutical company here before trying his hand in business. Besides running the two restaurants with the help of his wife, he was into the distribution of pharmaceutical products.

“After Russia won the first match of the World Cup, the footfall has gone up considerably. The Indians are also flooding in after the 6-9 p.m. game. That is the time both my restaurants remain full,” Prodyut said.

There are also plans to rope in registered fan clubs of Latin American countries, who will throng the restaurants during matches and then follow it up with after-game parties till the wee hours.

“I did get in touch with some of the fan clubs I had prior idea about. They agreed to come over and celebrate the games at our joints. Those will be gala nights when both eateries will remain open all night for them to enjoy,” Prodyut said.

Watching the World Cup is a dream come true for the couple, Sumana said.

“We want to make the Indians who have come here to witness the spectacle and feel at home too. We always extend a helping hand and since we are from West Bengal, we make special dishes for those who come from Bengal,” she added. (IANS)
