INDIA & KARNATAKA: SCIENCE & TECHNOLOGY / RESEARCH: IISc. Scientists Develop Composite Semiconductor for Next-Gen Foldable Phones and Wearable Devices

Traditional semiconductor devices – such as transistors – are either made of amorphous silicon or amorphous oxides, both of which are not flexible and strain tolerant.

Scientists in the Department of Materials Engineering at the Indian Institute of Science (IISc.) have developed a super flexible, composite semiconductor material that can have possible applications in next-generation flexible or curved display and foldable phones, and in wearable electronics.

Traditional semiconductor devices – such as transistors, the building blocks of most electronic circuits – used in display units are either made of amorphous silicon or amorphous oxides, both of which are not flexible and strain tolerant.

According to IISc, adding polymers to the oxide semiconductors may increase their flexibility, but there is a limit to how much can be added without compromising the semiconductor’s performance.

In the current study, published in Advanced Materials Technologies, researchers have found a way to fabricate a composite containing a significant amount of polymer – up to 40% of the material weight – using a solution-process technique, specifically inkjet printing.

In contrast, previous studies have reported only up to 1-2% polymer addition. Interestingly, the approach enabled the semiconducting properties of the oxide semiconductor to remain unaltered with the polymer addition. The large quantity of polymer made the composite semiconductor highly flexible and foldable without deteriorating its performance.

The composite semiconductor is made up of two materials – a water-insoluble polymer, such as ethyl cellulose that provides flexibility, and indium oxide, a semiconductor which brings in excellent electronic transport properties.

How researchers came up with the new material

To design the material, researchers mixed the polymer with the oxide precursor in such a way that interconnected oxide nanoparticle channels are formed (around phase-separated polymer islands) through which electrons can move from one end of a transistor (source) to the other (drain), ensuring a steady flow of current. The key to form these connected pathways, the researchers found, was the choice of the right kind of water-insoluble polymer that does not mix with the oxide lattice when the oxide semiconductor is being fabricated.

“This phase separation and the formation of polymer-rich islands helps in crack arrest, making it super flexible,” said Subho Dasgupta, Associate Professor in the Department of Materials Engineering, and corresponding author of the study.

Semiconductor materials are usually fabricated using deposition techniques, such as sputtering. Instead, Prof. Dasgupta’s team uses inkjet printing to deposit their material onto various flexible substrates ranging from plastic to paper. In the present study, a polymer called Kapton was used.

Potential use scenarios

Prof. Dasgupta adds that, in the future, such printed semiconductors can be used to fabricate fully printed and flexible television screens, wearables, and large electronic billboards alongside printed organic light emitting diode (OLED) display front-ends. These printed semiconductors will be low cost and easy to manufacture, which could potentially revolutionise the display industry.

The team has obtained a patent for their material, and plans to test its shelf life and quality control from device to device before it can be scaled up for mass production.

INTERNATIONAL & INDIA / KARNATAKA: SPACE TECHNOLOGY: 4th edition ‘G20 Space Economy Leaders’ Meeting (SELM) in Bengaluru: ‘Space technology has entered every household in one way or the other’

G20 Space Economy Leaders’ Meeting begins in Bengaluru.

The 4th edition of G20 Space Economy Leaders’ Meeting (SELM) commenced in Bengaluru on Thursday July 6.

This is the first face-to-face meeting under the G20 umbrella, with the previous meetings organised in virtual and hybrid formats. Heads of national space agencies from 18 of the G20 countries and nine of the 11 invited members are participating in the two-day meet whose theme is ‘Towards a New Space ERA (Economy, Responsibility, Alliance)’.

Senior representatives from 32 global industries, and 53 local industries, are also participating in the meet.

During the inauguration, Dr. Jitendra Singh, Minister of State, PMO; MoES; S&T; Ministry of Personnel, Public Grievance & Pensions; Dep. Of Space; Dept. of Atomic Energy, said that this gathering (G20 countries along with partner countries) represents nearly two-thirds of the world’s population, the best brains across the world in the space sector, 85% of the global GDP, and 75% of the world trade.

“You are not only spearheaders, torchbearers but also opinion-makers, and I am glad that India is in a position to share its inputs with other member countries as well. The new chapter of public-private participation is going to make it a value for all of us to learn the virtues of an integrated approach. An era of partnership is in the offing. Our concerns are common and our efforts have to be common. Therefore, the time has come to carry forward the collaboration to discover wider horizons in the times to come,” Dr Singh said.

“I hardly need to reiterate the importance that space technology has gained of late across the world. Rather, I would put it in a single sentence saying that space technology has virtually entered every household in one way or the other.”

He added that every aspect of human life, be it disaster management, agriculture, education, health, navigation, defence, is connected to space technology.

G20 Sherpa, Amitabh Kant, said the space economy is experiencing rapid growth with increasing revenues and more commercial actors entering the industry. “Studies project that space could become a trillion dollar sector in the coming decades. This exponential growth necessitates support from governments worldwide. That is why, we are discussing space as a formal element in the G20,” Mr Kanth said.

Round-table meetings for the heads of space agencies, panel discussions, bilateral meetings and a plenary session are a part of the first day of the event.

KARNATAKA: MEDIA: The little known Origins of ‘Kannada Press Day – 01st July’

A total of 7,850 copies of the MS were lithographed at the Basel Mission Press between 1st July 1843 and February 15, 1844.

On July 1, a very significant anniversary was celebrated by a certain section of media professionals – Kannada print journalists – in Karnataka. It was on this date, 180 years earlier, that the very first edition of the very first Kannada newspaper, the Mangaloora Samachara, was published, giving Kannadigas a window to the world, and to themselves, in their own language.

The remarkable story of the MS began in 1836, when Hermann Moegling, a young German missionary, arrived from the Basel Mission in Switzerland to the bustling markets of the ancient port city of Mangaluru. His brief was simple – to teach the word of the Gospel to ‘this stray flock.’ Recognizing that his facility with languages would be handy, the 25-year-old came armed with more than a smattering of Sanskrit, Arabic and English, but found himself stumped by one unexpected aspect of speaking Indian languages.

“What a demanding task to give up the guttural R so late in life,” he laments to his colleague, Hermann Gundert, in a biography the latter wrote, “and instead learn the R spoken here, which is produced by a fluttering of the tongue!” Gundert would have understood. He himself was based in Tellicherry; eventually, he would master Malayalam and, in 1872, compile the first Malayalam-English dictionary. (PS: Gundert was the grandfather of Hermann Hesse, the author of the 20th century classic, Siddhartha.)

Like Gundert, Moegling did not let the difficulties of pronunciation deter him. By 1840, he was not only speaking Kanarese fluently, but slowly and surely falling in love with the language. In 1841, the Basel Mission set up the first lithographic printing press of coastal Karnataka in Mangaluru’s Balmatta (today the Balmatta Institute of Printing Technology). The lithographic process involved printing off stone slabs inscribed with text that had been painted on to the stone with oil, fat or wax. Moegling was fascinated. In 1842, he had 1500 copies of a Kannada pamphlet printed and was thrilled by the ease and speed with which the information was disseminated to large numbers of his flock. By 1843, he was dreaming of a Kannada newspaper that had little to do with the Gospel.

The first edition of the four-page Mangaloora Samachara came out to great fanfare on July 1st, 1843. With a mission to “prevent the spread of rumours and untruthful things, and also to make available genuine information to the people at large”, the fortnightly had sections devoted to various topics, including oora varthamanagalu (local news), sarakarada niroopagalu (government – read: East India Company – laws and policies), sarva rajya varthamanagalu (news from all over the state, although it also included news from places further afield, like Afghanistan), nutanavada ashcharya suddigalu (new and sensational news), and even kathegalu (moral stories, songs about good conduct by Purandaradasa). Citizen journalism was also encouraged – “Anybody can send the news and it will be published” – but a cautionary corollary was issued alongside – “if it is true.”

A total of 7,850 copies of the MS were lithographed at the Basel Mission Press between 1st July 1843 and February 15, 1844. From its 15th edition onwards, the printing of the newspaper was taken over by the London Missionary Society in Ballari, which had a letterpress machine. Delighted with the response to MS from all over present-day Karnataka, Moegling expanded the scope of the newspaper, rechristening it Karnataka Samachara. Unfortunately, it did not have a long run. In its last edition, which came out in December 1844, Moegling spoke feelingly of a Samagra Karnataka, in which all Kannada-speaking regions would come together as one, little dreaming that it would be another 112 years before that fond hope came to fruition.

NATIONAL & KARNATAKA : INVENTIONS / RESEARCH / INNOVATIONS: 04 More New CSIR-CFTRI’s Technologies released in Mysuru

An anti-obese Barley-Seaweed based supplement ‘SeaSlim’, which is supposed to regulate body weight and manages obesity, has also been launched.

In the last seven decades, the Mysuru-based CSIR-CFTRI has developed nearly 400 technologies and over 4,500 licencees’ commercialised several technologies that were transferred to them by the premier institute.

On an average, 15 to 20 technologies were developed at the CFTRI annually and nearly 120-125 technologies were transferred every year, according to scientists.

At ‘One Week One Lab’ initiative that got off to a start at CFTRI here on Monday, July 3, four new technologies were launched by the dignitaries at the inaugural of OWOL. The CFTRI has proposed to release a total of 22 technologies during the weeklong OWOL.

The four technologies include barley-seaweed based anti-obese supplement ‘SeaSlim’; freshness keeper paper under the CSIR’s Floriculture Mission; process for the production of soluble and insoluble arabinoxylan from wheat bran, and production of baker’s yeast.

Freshness keeper paper is made with natural bioactive compounds. It can extend the shelf life of cut roses by 1-2 times longer, the CFTRI said.

A simple paper-based freshness keeper paper – a patented technology which is a chemical-free design to keep cut flowers fresh during transport and storage without disturbing the protocol of cut rose flowers. Freshness keeper technology is a paper wrapped with direct contact with rose flower petals that help enhance fresh-cut flowers’ quality and shelf life by two folds, a note said here.

During the export and transportation time, cut rose flowers have a shelf life of 10-12 days at 4 degrees C. With freshness paper, the shelf life is increased by 6-7 days – taking the total shelf life to 18-20 days.

“The scope of this technology is useful to Indian florists as well as other countries, more significantly who are in import and export of cut flowers as India is ranked 15th in the export of cut roses.”

This tech is chemical-free and inexpensive, reduces waste, and increases revenue. The tech helps farmers, importers, exporters and big and small vendors, the note added.

According to CFTRI, India is ranked third in the world in the prevalence of obesity. Owing to rising obesity cases, anti-obese foods are flooding the markets. The CFTRI has developed a barley-seaweed based anti-obese supplement called ‘SeaSlim’ having qualities of brown algae and barley for managing obesity. “SeaSlim can be used as a potent antioxidant food. It lowers fat absorption in the small intestine. It lowers the risk of obesity and diabetes. It helps in regulation of body weight by reducing the food intake and can be used as a low-glycemic index food. It can be recommended as a thermogenic food to manage obesity,” the release issued by CFTRI said.

NATIONAL & KARNATAKA: DEFENCE SERVICES / TECHNOLOGY :DRDO, Navy Fly TAPAS Drone, Land it on Warship 

 The TAPAS UAV took off from Chitradurga’s Aeronautical Test Range (ATR) and flew 285 km and landed successfully on INS Subhadra.

The Defence Research and Development Organisation (DRDO) and the Indian Navy successfully demonstrated the transfer of command and control capabilities of TAPAS unmanned aerial vehicle (UAV).

The TAPAS UAV took off from Chitradurga’s Aeronautical Test Range (ATR) and flew 285 km and landed successfully on INS Subhadra. According to the Navy, the vessel was 148km off the Karwar Naval base. A ground control station and two ship data terminals were installed on INS Subhadra to control the UAV.

The UAV took off at 7.35 am from the ATR and soared to a height of 20,000 feet and flew for three-and-a-half hours non-stop to land on INS Subhadra. “After this test, the UAV flew back to the ATR safely,” said the Navy.

“This test is called C2 — command and control capabilities — to check the ability of the operator to control the drone’s flight, sensors and payloads. C2 capabilities are essential for the safe and effective operations of a drone. This is a Medium Altitude Long Endurance (MALE) drone, which has a flight endurance of 24 to 48 hours,” informed Girish Linganna, a Bengaluru-based defence expert.

TAPAS was designed and developed by the Aeronautical Development Agency and can be used for patrolling and intelligence gathering for all the three forces. These UAVs are considered the Indian version of Predator drones of the United States.

They are equipped with electro optics sensors to capture images and videos both during the day and night, long-range electro optics sensors to take images and videos from long distances that can be used for surveillance and reconnaissance missions and provide information about enemy movements and activities, Synthetic Aperture Radar (SAR) that uses a technique called synthetic aperture to create high-resolution images that can be used in all-weather conditions to obtain ground surface details like terrain features and objects, electronic intelligence, communication intelligence and other features.

KARNATAKA: RURAL INNOVATION / AGRICULTURE : Siddapur Farmer Vidyadhar Bhat Designs Wonder Modified Vehicle that carries 300 kilos of load

 Though the vehicle looks like a scooter, it does work of an autorickshaw. It is also quite useful for the farmers.

A farmer who was tired of carrying things on his shoulders has designed this vehicle, which is developed from his old TVS moped.

The farmer who has designed this unique vehicle is none other than Vidhyadhar Bhat, a resident of Unchalli of Siddapur taluk of the district.

An old TVS moped that was lying in Vidhyadhar Bhat’s house was getting rusted. So Bhat thought of using it as a cart vehicle and a sketch was made in cooperation with local engineer Prashanth. Later, they developed a three-wheeler vehicle having tyres of a scooty and an auto.

The vehicle has the engine of CT 100 and has brakes of an Omni vehicle. A  container that is fitted on the backside can carry up to 300 kilos of load. The vehicle has a fan and an intercooler as well.

The vehicle gives a mileage of 20 km to a litre if the load is full. Otherwise it can give up to 30 to 35 kilometers to a litre. On the whole, this wonder vehicle is farmer-friendly. This vehicle allows the farmer to finish off his work without depending much on labourers for farm-related work.
