Researchers at the Centre for Nano and Soft Matter Sciences (CeNS) in two studies have developed novel smart-window technologies which do not require external electrical energy for their operational needs.

“Existing electrochromic smart-window technology requires external power for its operational needs. It is limited to changing colour from transparent to blue and vice-versa (switching optical transparency functionality) upon application of an electrical stimulus and blocks both visible and near-infrared radiation, leading to a decrease in the room temperature,“ the Department of Science and Technology stated.

How it is done

Researchers, led by Ashutosh K. Singh at CeNS, have addressed this through two studies. In one, they have removed the dependency of electrochromic devices on external electrical power for their operational needs. In the second one, they have made the fabrication process more affordable.

“The resulting self-powered electrochromic smart window operates through the power stored in its switching operation from transparent to coloured states. This enhances the operational energy efficiency, affordability and energy storage functionality of the new smart-windows technology,” the department said.

In the first work, the CeNS team has developed a device that can store electrical energy by changing colour upon the application of a small electrical stimulus generated through electrochemical reactions taking place within the device itself resulting from the device configuration.

In the second research work, Dr. Singh’s team developed the fabrication process of electrochromic smart windows and made it more affordable by using an industrially adaptable solution-based spray coating approach. Under this process, the affordable electrochromic smart-window technology retained its functionalities, such as the seamless switching between coloured and transparent states while possessing energy storage capabilities that can power the portable device.

Sustainable approach

“The development of these electrochromic devices represents a major step towards sustainable energy utilisation in buildings. By optimising the process parameters and adopting cost-effective materials, we have created devices that not only enhance energy efficiency but also offer scalable and affordable solutions for modern infrastructures,” Dr. Singh said.

The Tata family’s association with Karnataka goes back decades, when Jamsetji Nusserwanji Tata along with the then Maharaja of Mysuru helped set up the Indian Institute of Science (IISc) in the early 1900s.

Eminent industrialist Ratan Tata, who breathed his last on Wednesday, had a strong connection with Karnataka, something that he fostered over the years, keeping with the legacy of the Tata family.

The Tata family’s association with Karnataka goes back decades, when Jamsetji Nusserwanji Tata along with the then Maharaja of Mysuru helped set up the Indian Institute of Science (IISc) in the early 1900s.

This relationship would continue for years to come, with Ratan Tata, as chairman of Tata Sons, later becoming the president of the IISc Court, the highest decision-taking body of the prestigious institute.

But it didn’t end there.

A frequent attendee at Bengaluru’s Aero India air shows, Ratan Tata took audiences by surprise in 2007 when he flew a Lockheed Martin F-16 jet.

A few years later in 2011, Tata, then aged 74 years, flew in on an F/A-18 Super Hornet.

Commenting on his experience in flying the advanced fighter jet in 2011, Tata said at the time, “During the ride, we performed aerobatics. We flew low, high and went through some accelerations. I loved it and I would not mind doing it all again.”

“This is not my first time flying in fighter jets but definitely my favorite one. The Bengaluru aero show gave me a terrific experience,” he added.

Although the industrialist did not fly any sorties after 2011, he was still a frequent attendee, and was spotted at many editions thereafter.

As Bengaluru and Karnataka prospered, Tata also saw it as an opportunity, and highlighted the state’s potential in sectors such as information technology (IT) and aerospace, and pitched Karnataka as a state ripe for investment.

During the Invest Karnataka Global Investors’ Meet in Bengaluru in 2016—attended by then Chief Minister Siddaramaiah, Union Minister Arun Jaitley, among others—Ratan Tata asserted that the state “boasts remarkable human capital.”

“I’m not making this statement based on promises but on my own interactions and experiences with the state over the years,” he said.

When the researchers shined ultraviolet (UV) light on their supercapacitor, they noticed a huge increase in the capacitance, several times higher than previously reported supercapacitors.

Researchers from the Department of Instrumentation and Applied Physics (IAP), Indian Institute of Science (IISc), along with other collaborators have designed a unique supercapacitor that can be charged by shining light on it. They can be used in various devices, including street lights and self-powered electronic devices such as sensors, said the research paper released on Thursday.

Capacitors are electrostatic devices that store energy as charges on two metal plates called electrodes. Super-capacitors are upgraded versions of capacitors – they exploit electrochemical phenomena to store more energy, said Abha Misra, IAP Professor and the co-author of the study. The research has also been published in the Journal of Materials Chemistry A. The electrodes of the supercapacitor are made of Zinc Oxide (ZnO) nanorods grown directly on Fluorine-doped Tin Oxide (FTO), which are transparent.

They were then synthesised. The two semi-conductors were then aligned to enhance the photo-recharging performance, explained Pankaj Singh Chauhan, co-author of the study paper and CV Raman postdoctoral fellow in Misra’s group at IISc. Chauhan added that since FTO is transparent, it allows light to fall on the optically active ZnO nanorods, which charge the supercapacitor.

When the researchers shined ultraviolet (UV) light on their supercapacitor, they noticed a huge increase in the capacitance, several times higher than previously reported supercapacitors. They also noticed two unusual properties. First, they found an increase in capacitance under light illumination with increasing voltage. This is called as necking behaviour, said AM Rao, Professor, Clemson University, USA, and co-author. Second, the team found that with the liquid electrolyte, the energy stored in the supercapacitor increased upon fast charging under UV light.

Mihir Parekh, a postdoctoral researcher in Rao’s group, developed theoretical models to explain these novel observations. To design their present supercapacitor, the team explored two key ideas. First, the surface area of the electrodes was increased by combining two optically active semiconductor interfaces in a way that maximises interaction with light, leading to higher charge generation. Second, a liquid electrolyte was used to ensure an effective electric double layer (EDL). Together, these resulted in superior performance, Misra said.

The FWD 200B is equipped with optical payloads for surveillance and missile-like weapons for air strikes and bombing.

Bengaluru-based unmanned aerial vehicle (UAV) and component private manufacturing company, Flying Wedge Defence and Aerospace (FWDA), on Tuesday announced its successful maiden flight of India’s first indigenous unmanned bomber aircraft, the FWD 200B, marking a milestone in the country’s defence sector.

The UAV is classified as a Medium Altitude (15000 ft), Long Endurance (MALE) Unmanned Combat Aerial Vehicle (UCAV) . The FWD 200B is equipped with optical payloads for surveillance and missile-like weapons for air strikes and bombing.

FWD 200B features a wingspan of 5 meters (16.4 feet) and a length of 3.5 meters (12.1 feet), making it compact yet powerful. Despite its size, the aircraft has a maximum take-off weight of 102 kg and can carry a payload capacity of 30 kg, making it capable of conducting significant missions with precision.

Operating at a cruise altitude of 12,000 feet and reaching an absolute ceiling of 15,000 feet, the FWD 200B can fly at a cruise speed of 152 km/h, with a maximum speed of 250 km/h. Its operational versatility is further highlighted by its runway requirement of just 300 meters, allowing it to operate from shorter airstrips.

With an endurance of 7 hours and a range of 800 km, the FWD 200B ensures extended mission capabilities, providing substantial coverage without the need for frequent refueling or landing.

The FWS 200B was tested at a classified location, and the first flight is touted as the fulfillment of India’s long-awaited dream of producing a combat UAV domestically right from the subsystems.
