IISc. researchers have nano solution for wastewater treatment

They developed a metal organic framework (MoF) nanocomposite by intercalating the properties of graphene oxide and UiO-66-NDC.

Researchers in the Indian Institute of Science’s (IISc.) have developed a novel nanocomposite material for improved wastewater treatment.

A team of the Interdisciplinary Centre for Water Research (ICWaR) in the IISc., led by Praveen C. Ramamurthy, has developed a metal organic framework (MoF) nanocomposite by intercalating the properties of graphene oxide and UiO-66-NDC.

Heavy metals

According to IISc., industrial effluents containing heavy metals have polluted our water sources for decades. Lead, a heavy metal commonly found in discharge from paint and battery manufacturing plants, is a major water pollutant whose presence severely affects human and animal health.

In recent years, scientists have turned to nanotechnology to develop absorbent materials that can remove heavy metals for improved wastewater treatment.

However, existing adsorption materials and technologies are expensive, and their applications are limited by where they can be implemented and how efficiently they can adsorb lead. This demands the development of novel, low-cost and structurally stable composite materials for wastewater treatment. To this end, ICWaR researchers have developed a novel nanocomposite material.

The researchers have demonstrated that the new nanocomposite can adsorb lead (Pb) from simulated wastewater systems.

Four-fold capacity to absorb lead ions from wastewater

The team demonstrated that the newly developed MOF nanocomposite adsorbent has approximately four-fold enhanced capability in removing lead ions from wastewater compared to previously reported studies of graphene oxide. The material exhibits a stable crystalline structure. Modelling and simulation results also support enhanced efficiency in lead adsorption due to the adsorbent molecular architecture.

The new nanocomposite has improved adsorption and high regeneration and reusability capacities, making it an effective tool in the wastewater treatment of lead ions.

IISc student wins prize at Berlin summit for TB diagnostics tool

An IISc student won third prize at an international summit held in Berlin, Germany, for a device that could make tuberculosis (TB) diagnosis cheaper and more accessible.

Ayushi Chauhan, a PhD scholar at IISc’s chemical engineering department, was awarded third prize under the ‘Breakthrough of the Year Emerging Talents’ category at the Falling Walls Lab and Science Summit 2022 in Germany. She was earlier the winner of Falling Walls Lab India 2022, leading her to represent the country during the global summit.

She and her adviser, Dr Bhushan Toley, developed a pocket-sized device for the detection of both regular and drug-resistant tuberculosis, that makes the diagnostic portion near equipment-free. “The device reduces instrumentation cost by 99.6% and testing cost by 87%, which can be reduced even further. Only around one-third of tuberculosis cases are actually reported.

This is due in large part to equipment needs,” she said, during her pitch at the summit. She said the diagnosis method was visually similar to that of a home pregnancy test and Covid tests. “I believe this invention can bring an end to tuberculosis by 2035,” she said.

Vikram Kirloskar – The man who brought Toyota to Karnataka

Vikram Kirloskar brought global auto giant Toyota to Karnataka in 1997, when the State wasn’t yet a big name in the global business arena.

Way back in 1997, when Karnataka wasn’t yet a big spot on the global business map, auto major Toyota set up a manufacturing facility at Bidadi, on the outskirts of Bengaluru. The man who was instrumental in bringing the Japanese automaker to Karnataka was Vikram Kirloskar who passed away on November 29.

The initial efforts towards bringing Toyota Motor Corp to India were made during the tenure of Chief Minister Veerappa Moily in the early 1990s, and were later followed up by his successor H.D. Deve Gowda. During J.H. Patel’s tenure, Toyota Kirloskar officially started its operations in Karnataka. Thereafter, the business savvy S.M Krishna and his industrious industries minister R.V. Deshpande extended support to the venture.

Although multiple Chief Ministers and their industries ministers were involved in bringing, hosting and settling Toyota at Bidadi, one key person who worked tirelessly from outside was Vikram Kirloskar, who is a mechanical engineering graduate from the Massachusetts Institute of Technology (MIT), U.S.A.

Industries Minister Murugesh Nirani said, “He was a dear personal friend, an industry friend and, more importantly, a genuine human being who was always ready with a smile. With the passing of Vikram, a prominent face and a pillar of the business community of Karnataka is no more.”

The Kirloskar family hails from Haveri in the Dharwad region. They have been running various businesses, including automotive engineering, pumps, gensets, and machine tools for over 100 years. Vikram Kirloskar became the mainstay of ‘Karnataka Inc.’ with Toyota Kirloskar in 1997.

Since its inception, Toyota has invested over ₹20,000 crore in Karnataka, and Mr. Kirloskar’s personal commitment in 2010 was ₹1,500 crore.

“He has been a great help in organising Global Investors’ Meet. He and (his wife) Geetanjali came with me for a road show in the U.S. prior to GIM in 2010,” recalled Mr. Nirani.

A doyen of the automotive industry, Mr. Kirloskar was extremely supportive of young people and their business ideas.

Addressing a trade body event that had several youngsters in the audience recently, he said, “You are the future leaders. You should soon be sitting here where I am sitting.”

The fourth-generation entrepreneur of the Kirloskar family leaves behind his wife Geetanjali and daughter Manasi, who works in the company.

HAL delivers 16th ALH Mk-III helicopter to Indian Coast Guard

Hindustan Aeronautics Limited (HAL) has handed over the last of the 16 Advanced Light Helicopters (MK-III, Maritime role) to the Indian Coast Guard at a programme here on Tuesday.

The chopper was handed over to DG, Coast Guard, V.S. Pathania, in the presence of senior officials from the Indian Coast Guard and HAL.

“We are proud to be associated with HAL and happy to issue a Letter of Intent (LoI) for nine more helicopters. Despite Covid-19, HAL delivered all the helicopters at the shortest time with seamless production activities and this allows us to strengthen India’s maritime security,” Pathania said.

The DG had signed a contract with HAL for the supply of 16 ALH Mk-III in March 2017.

C.B. Ananthakrishnan, CMD, HAL, said a unique feature of the contract has been the performance based logistics (PBL) – the one stop solution for maintenance of these helicopters by HAL.

“This will serve as a benchmark for all our future contracts and boost our resolve to work with private partners to speed up the work in the interest of all our customers and strengthen Make-in-India activities in the defence eco-system,” he said.

S. Anbuvelan, CEO (Helicopter Complex), HAL, pointed out the major challenges in execution of the contract that included integration of new systems sourced from foreign OEMs, conducting flight trials for certifications and overcoming disruptions in the supply chain due to lockdowns.

ALH Mk-III is indigenously designed, developed and produced by HAL. The company has so far produced more than 330 ALHs, a versatile helicopter which has logged more than 3.74 lakh flying hours.

Fortis performs 72 robotic surgeries in three months

Fortis Hospital has successfully performed 72 robotic surgeries (knee and hip replacement) since September 2022. To create awareness about the efficiency of robotic surgeries, the hospital launched an initiative to perform 100 robotic surgeries without adding any additional costs.

Akshay Oleti, business head of the hospital, said the the hospital currently provides robotic surgeries at the same cost as conventional surgeries to ensure the advanced procedures are more accessible. In October, Ndeshiwangisa Senyaeli, a 66-year-old Tanzanian woman, was treated at the hospital.

She was even unable to perform basic chores for 15 years and had co-morbidities like hypertension, asthma, heart defects among others earlier. The doctors explained that both her knees were damaged due to osteoarthritis.

She could barely take a step when she arrived at the hospital. Dr Narayan Hulse, Director – Department of Orthopaedics, Bone & Joint Surgery, Fortis Hospital, explained that they performed a surgery using the Mako Robotic Technology within a gap of three days. The robot helped create a 3D virtual model of the damaged knee and plan the corrective surgery accordingly.

Dr Hulse explained that often, patients would be unhappy with the knee surgeries as the metal plates would often end up being inaccurately placed. With the MAKO robot, the technology has evolved as the robot calculates everything, all the angles and cutting of the bones as well, reducing inaccuracy to almost nil.
