Hemalatha Jain is reinventing ancient, forgotten weaves from India’s heartlands

The Gomi Teni sari from North Karnataka, was worn by women in the 12th century.

“They haven’t been worn in over 40 years, though their border styles are used in some versions of the Ilkal sari,” says Hemalatha Jain, who is bringing the sari to Bengaluru, after having worked on its revival through her Punarjeevana initiative which seeks to empower the weavers and sustain such crafts.

“The sari’s motifs (especially on the border) evoke the patterns of jowar seeds, a prominent crop in North Karnataka, and are represented by the herringbone stitch. Gomi Teni saris used to be gifted to pregnant women and were worn by married women during the Sankranti festival. The sari is gifted on these occasions because it represents prosperity.”

She has already revived the Patteda Anchu craft, in collaboration with local craftsmen in Karnataka. She began her work in the town of Gajendragarh (Gadag district).

“When I was working in Karnataka on these crafts, I came across historical evidence for seven saris. The Gomi Teni is among them. It is an everyday kind of sari worn by farmers and other locals. It died out because of power looms and the availability of cheaper material. I was able to get a worn out sample of the sari and I decided to stick with cotton for the revival because of the hot weather in these regions,” explains Hemalatha.

“The reason I took this up is that many weavers want to work with art and I wanted to help them increase the number of looms so more artisans can come together and create a prosperous cluster.”

Beginning with one weaver, she now has a team of 45, including over 35 weavers and other artisans associated with ancillary activities around weaving.

Through her intervention in the revival process, she has brought out saris featuring check body with 2/20 s × 2/40s count and a five-inch border with Gomi design. The saris are reversible with two different pallus (there is no right-side or wrong-side to the sari) and two different borders. They have been dyed using eco-friendly dyes.

“The saris were traditionally made in red, brown and yellow because those were the colours that were available there. They didn’t use colours like black. But now we have saris in a range of colours from navy blue to black and pastel shades, apart from red,” explains Hemalatha. “We are also working to use as little water as possible because North Karnataka doesn’t have much water. Our saris are low-maintenance, the colour fastness is good. They can be washed in the machine, they don’t need any starch, they don’t even need to be ironed.”

Hemalatha brought in these characteristics by keeping the yarn count thick, so the sari doesn’t normally wrinkle.

“I am working on more such saris but I don’t want to talk about them just yet because there is a high danger of replication and duplication in this field.”

The Gomi Teni sari will be brought to Bengaluru tomorrow at Kamalini, the craft store by Crafts Council of Karnataka.

The saris will be on display at Sri Bhooma, 17th Cross, Malleshwaram until March 10. For details, call 23567470.

The flag will be yellow, red and white with the State emblem in the middle

Karnataka government, on Thursday, took a historic decision to have separate State flag.

The decision was taken at a meeting convened by Chief Minister Siddaramaiah to discuss the recommendations of the nine-member flag committee. The committee had recommended yellow, red and white with the State emblem in the middle. The meeting was attended by representatives of Kannada organisations, littérateurs and official representatives.

After arriving at a consensus with regard to accepting the flag recommended by the expert committee, an elated Chief Minister said: “The long pending demand of having separate State flag has finally been realised with the support extended by all the concerned.”

Exhibiting the State flag, he said the “government, which felt the need of having separate flag, lent voice to the demand by setting up expert committee to decide on colour and emblem of the State flag.”

An expert committee was constituted following representation from renowned journalist and writer Patil Puttappa.

After examining the legal and Constitutional provisions, the committee submitted its report on February 6. “When the report was tabled in the State Cabinet, it was unanimously accepted. This further empowered me to take a final call on the issue after consulting leaders of Kannada organisations. Leaders of Kannada outfits agreed to the recommendations on the design of State flag,” he added.

In the tri-colour Stage flag, white symbolises peace with State emblem. While yellow symbolises the auspiciousness and well-being of Kannadigas, the red colour symbolises courage.

“The state government had no power to announce its State flag. A proposal in this regard will be sent to the union government. We will urge the centre to approve the proposal and make an official announcement at the earliest,” Mr. Siddaramaiah said.

If centre agrees to the proposal, Karnataka will be second state in the country to have a separate State flag, after Jammu and Kashmir. This is due to J&K’s special status under the Constitution. “There is no opposition for States to have separate flag in the Constitution. But, the State flag will always fly below the National flag, as prescribed,” said Mr. Siddaramaiah.

Made two round trips on day one between KIA and Electronics City

App-based taxi service took on a whole new meaning on Monday when Bengaluru’s first helitaxi service took off, ferrying passengers from Kempegowda International Airport (KIA) to Electronics City in 15 minutes. The helitaxi made two trips, with the first one taking off at 6.30 a.m.

The helitaxi, touted to be the first such service in the country, was announced in August 2017 by Union Minister of State for Civil Aviation Jayant Sinha. The service is being offered by KIA in partnership with Thumby Aviation Pvt Ltd, in an effort to reduce the time taken to travel to the city from the international airport.

According to Capt. K.N.G. Nair, Chairman and Managing Director, Thumby Aviation, the helicopter can ferry six passengers. “On the first trip, we had four passengers from KIA. On the way back from Electronics City, we had five passengers. In the second trip, we had three passengers from KIA and two on the way back.” He added that they did not accept too many bookings for Monday as it was the inaugural service.

How does it work?

Those who want to avail the service can book a seat through the app (Heli Taxii). The fare is ₹4,130 per person, including GST. Once passengers exit the arrival lounge, the company has arranged vehicles to ferry passengers to its facility in the KIA premises, which would be a four-minute ride. For those heading to KIA, the company vehicle will drop passengers at the departure lounge.

At Electronics City, the helicopter will land in Thumby Aviation’s facility in Phase I, near the toll plaza.

More helicopters soon

At present, the company is operating only one helicopter. The number will increase depending on the demand. “Our service is not affecting any activities at the international airport. We have a different route, which is approved by the Ministry of Defence and Airports Authority of India, which does not interfere with the air force related traffic in Yelahanka or HAL either,” Mr. Nair added.

Mobile nanotweezers can pick, drop live bacteria

The work of Souvik Ghosh (right) and Ambarish Ghosh overcomes the earlier limitation of nanotweezers that were only able to trap and hold the molecules.
The work of Souvik Ghosh (right) and Ambarish Ghosh overcomes the earlier limitation of nanotweezers that were only able to trap and hold the molecules.

Can be used in microfluidics and in biomedicine.

A team from Indian Institute of Science, Bengaluru, has succeeded in designing a new class of mobile nanotweezers that can pick up, hold and move tiny cargo, the size of molecules, in a fluid. The work by Souvik Ghosh and Ambarish Ghosh of Centre for Nanoscience and Engineering, IISc, overcomes the earlier limitation of nanotweezers that were only able to trap and hold the molecules. Apart from nanoscale assembly – where tiny objects such as nanodiamonds or quantum dots need to be picked up and moved to a desired location — this has applications also in microfluidics, where live bacteria need to be manipulated and in biomedicine.

Limitations

Picking up and moving molecules suspended in a fluid, such as a colloid, is a busy area of research. Plasmonic nanotweezers — nanosized tweezers made of noble metals, which have been studied so far to trap cargo, have the limitation that they are fixed in position. When they are illuminated by light, they develop a ‘potential gradient’ around them. This is like a slope, and nearby particles get attracted to the potential’s minimum just as things roll down a slope. However, the limitation is that it can only capture particles that are within the range of the field.

In the new work, the robotic, mobile nanotweezer can pick up tiny particles and move them over a short distance when the microrobots are subjected to an external magnetic field. “We can tune our trapping and releasing mechanism by subsequently turning the incident illumination on and off. To move these nanotweezers, we use a rotating magnetic field which rotates the helix [of the nanotweezer] and [moves it] like a cork-screw,” says Souvik Ghosh, first author of the study published in Science Robotics.

Thermal fluctuations

The colloidal particles move due to thermal fluctuations, therefore it is very difficult to manipulate the nanoparticles. Also as the size of the particles decreases, so, too, does the trapping force. The researchers’ main challenge was to overcome this and generate sufficient trapping force using a small amount of laser power. To achieve this, small helical structures are grown on a pre-patterned substrate by electron beam evaporation of silicon dioxide (made of mostly glass). “The substrate is kept at an extreme angle to the incoming vapour flux and rotated slowly to achieve the helical shape. Apart from glass, we also combine silver (plasmonic properties) and iron (magnetic properties) nanostructures at appropriate places on the helical body,” explains Souvik Ghosh, in an email to The Hindu.

As a next step, the team is working on parallelising the process. Thus, a series of microrobots will work together like an assembly line. “This will allow us to scale up our technology and will surely have commercial impact, and initial results are promising,” says Mr Ghosh.

JNCASR’s novel material to convert waste heat into electricity

Ongoing effort : We are now trying to increase the efficiency, says Kanishka Biswas (left) .
Ongoing effort : We are now trying to increase the efficiency, says Kanishka Biswas (left) .

With nearly 65% of utilized energy wasted, the focus is on materials to mitigate this

A novel compound that exhibits poor thermal conductivity in the 25-425 degree C range but shows good electrical conductivity has been developed by a team of researchers led by Dr Kanishka Biswas from Bengaluru’s Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR). The compound, silver copper telluride (AgCuTe), shows promise as a thermoelectric material for converting waste heat into electricity.

Since nearly 65% of utilized energy is wasted as heat, the focus is on developing materials that exhibit good thermoelectric property with both glass- and metal-like properties. Potential applications of the thermoelectric technology are in automobile industry, chemical, thermal and steel power plants where large quantities of heat are wasted.

Due to the low thermal conductivity of the material developed by JNCASR, one end of the 8 mm-long rod that is contact with waste heat remains hot while the other end maintains cold temperature. The temperature difference is essential for the generation of electrical voltage. At the same time, the material exhibits good electrical conductivity like metal. The results were published in the journal Angewandte Chemie.

In the AgCuTe material, the silver atoms (cation) are weakly bound, giving rise to poor thermal conductivity due to the slow vibration of the lattice (soft lattice). At high temperatures, copper in the material further lowers the thermal conductivity along with silver. “Since the silver lattice vibrates slowly, it provides record low thermal conduction of 0.35 W per metre per kelvin, which is actually close to the glass,” Dr Biswas says.

“Both cations [silver and copper] contribute to low thermal conductivity but silver contributes more. Over 170 degree C, both silver and copper ions flow like liquid within the rigid tellurium sublattice, thereby reducing the thermal conductivity to the level of glass without affecting the hole (electrical carrier) transport,” says Subhajit Roychowdhury from JNCASR and first author of the paper.

Tellurium lattice

In contrast, the tellurium atoms (anion) are strongly bound and the lattice is very rigid. The strongly bound tellurium provides a conduction channel for holes thus rendering good electrical conductivity as seen in metals.

“By combining silver and copper with tellurium we have made our material as a combination of glass and metal — poor thermal conductivity and good electrical conductivity,” Dr Biswas says.

“Silver telluride does not have good thermoelectric property because it has higher thermal conductivity than our material,” says Roychowdhury.

It is a challenging task to have glassy and metallic properties in a single material, which is the fundamental challenge in the field of thermoelectrics. “We addressed this challenge through structural chemistry by creating a bonding hierarchy in the material,” Dr Biswas says.

The calculated efficiency to convert heat into electricity is 14% for the new material developed by JNCASR researchers. The lead telluride (PbTe) has higher efficiency of 18%. “But unlike lead telluride that contains lead, which is toxic, our material is lead-free,” he adds. The theoretical calculation to know the electronic structure was done in collaboration with Prof. Umesh V. Waghmare of JNCASR and coauthor of the paper. “We are trying to increase the efficiency by doping with different cations and anions,” Dr Biswas says.

This Anglo-Indian settlement was football’s birthplace in Bengaluru

Austin Town has changed. As in many erstwhile British Cantonment and Anglo-Indian localities, the early settlers have sold off property to migrate elsewhere. Colonial homes with monkey-tops and tiled roofs have made way for more ‘practical’ buildings.

For 50-year-old engineer, Kevin Vieyra, the biggest drawback of these changes is the fragmentation of the community. Vieyra’s grandmother Enid Wilson, an Irish woman was the sergeant of the locality in the 1900s, was one of the earliest residents of the Anglo-Indian quarters. She was the go-to person for anyone with a problem that needed solving. “Even when I was growing up, Austin Town was a close-knit community where it did not really make a difference which home you belonged to,” Vieyra recalled.

Austin Town was built in the early 1920s when the British authorities decided to re-settle workers and lower-income residents in the aftermath of the bubonic plague of 1898. The locality was made up of small cottages. Original settlers included the Anglo-Indian community and a large Tamil population that traced its ancestry to the soldiers and workers brought to the Cantonment by the British after the fall of Tipu Sultan in the Fourth Anglo-Mysore War in 1799.

According to Mansoor Ali, founder of Bengaluru By Foot, “The locality is named after Sir James Austin Bourdillon who was born in Madras in 1848 and was educated at Marlborough, England. He held multiple official posts in Bengal and Patna before becoming the Resident of Mysore between 1903 and 1905.”

The sanitary works in Austin Town were designed by WH Murphy, an engineer in the British cantonment, after whom Murphy Town is named. While James Austin himself enjoyed cricket and rifle shooting, the locality named after him is known to be the birthplace of football in Bengaluru.

 It is said that the Italian prisoners of war, held here during World War II, passed the game on to the locals. Among the first Olympians from India (in the Games of 1948 and 1952) were footballers Anthony, Kanniah, Raman and T Shanmugam — all of who were from Austin Town. So were other football greats Ulaganathan and former India football captain Carlton Chapman.

Even today, the children of the locality practise football with as much fervour as they play cricket. Twenty years ago, the locality was renamed as F Kittel Nagar, after 18th century German missionary Rev Ferdinand Kittel.

CM inaugurates first phase of Pavagada Solar Park

Chief Minister Siddaramaiah inaugurated the first phase of Pavagada Solar Park at Thirumani in Pavagada taluk of Tumakuru district on Thursday.

Addressing a large gathering, Mr. Siddaramaiah termed the solar park as the “eighth wonder of the world.” He said that “we are thankful to all those farmers who have leased out their land to the government for the project.”

In the first phase, the solar park will produce 600 MW. A total of 2,300 farmers of Pavagada have leased out 13,000 acres of land at Rs.21,000 per acre per annum. This will help to boost the economic activities in the most backward taluk. Before the solar park was established, the land rates were around Rs. 25,000 per acre but now they have risen to Rs. 4-5 lakh.

Energy Minister D.K. Shivakumar said that Karnataka will become self-reliant in the production of power and there will be no need to depend on other States. Pavagada Solar Park will be completed by December 2018 and will generate 2000 MW of power, he added.

District-in-charge Minister T.B. Jayachandra, MP Chandrappa, MLA Thimmarayappa, former Minister Venkataramanappa and others were present.
