IIT-Bombay researchers patent technology that will save crores for steel industry and reduce emissions

A groundbreaking energy-efficient carbon dioxide (CO2) capture technology has been developed, offering the potential to revolutionize the steel industry while advancing India’s aim of achieving net-zero emissions by 2070. Developed by the National Centre of Excellence in Carbon Capture and Utilisation (NCoE-CCU) at IIT Bombay with support from the Department of Science and Technology (DST), this innovation enables the conversion of CO2 into carbon monoxide (CO) under electrocatalytic conditions at ambient temperatures, even in the presence of water.

Dr Arnab Dutta and Dr Vikram Vishal, along with dedicated researchers at the NCoE-CCU, have successfully patented the CO2-to-CO conversion technology. Moreover, their work is set to be published in the prestigious international journal, Nature Communications.

Carbon monoxide (CO) is widely used in the industrial sector, particularly in the form of synthesis gas (syngas). In the steel industry, CO is indispensable for converting iron ores into metallic iron within blast furnaces. However, the traditional method of CO generation involves the partial oxidation of coke or coal, leading to substantial CO2 emissions as a byproduct. 

The innovation developed by IIT Bombay’s NCoE-CCU offers a more sustainable approach by converting emitted CO2 into valuable CO. What sets this technology apart is its ability to function at ambient temperatures (25-40 °C) with minimal energy requirements.

This electrocatalytic reaction can efficiently harness energy from renewable sources, such as solar panels or windmills, ensuring a carbon-neutral process for converting CO2 to CO. Notably, this advancement aligns with India’s environmental goals and represents a critical pathway for mitigating greenhouse gas emissions.

The technology has immense potential for various industrial applications and is currently in the process of scaling up, thanks to the recent incubation of UrjanovaC Private Limited. The steel sector, in particular, stands to benefit from this breakthrough. Additionally, another technology for aqueous-based CO2 capture and conversion to calcium carbonate, originating from DST-supported NCoE-CCU activities, has been licensed to UrjanovaC Private Limited, incubated through SINE at IIT Bombay.

NATIONAL: MEDICAL RESEARCH : The Indian Council of Medical Research (ICMR) completes Clinical Trials of World’s First Injectable Male Contraceptive; study claims it’s safe

The findings of the phase-III clinical trial, which involved 303 candidates aged 25-40 years, were published in the international open-access Andrology journal last month.

The Indian Council of Medical Research (ICMR) has completed the clinical trials of the world’s first injectable male contraceptive which showed that it is safe and highly efficacious without any serious side effects.

The findings of the phase-III clinical trial, which involved 303 candidates aged 25-40 years, were published in the international open-access Andrology journal last month.

The open-labeled and non-randomized, multi-centre hospital-based phase-III clinical trials were carried out at five different centres (New Delhi, Udhampur, Ludhiana, Jaipur and Kharagpur) and coordinated by the ICMR, New Delhi.

Permission to conduct phase-III clinical trial was granted by the Drugs Controller General India (DCGI) and approved by the institutional ethical committees of the respective centres.

As part of the study, 303 healthy, sexually active and married men and their healthy and sexually active wives who came to the family planning clinic and department of urology or surgery for vasectomy or No Scalpel Vasectomy (NSV) were identified.

The men were injected with 60 mg of Reversible Inhibition of Sperm under Guidance (RISUG).

“The overall efficacy of RISUG with respect to achieving azoospermia was 97.3 per cent and based on pregnancy prevention was 99.02 per cent without any serious side effect,” the study stated.

“In the history of contraceptive development, RISUG presents the highest effectiveness compared to all other contraceptives both male and female as they were at the threshold of induction into a mass contraception program,” it said.

According to the study, with an ever-increasing world population, there is an urgent need to develop modern methods of male contraception for population control.

Even though vasectomy is quite effective as a contraceptive measure, some major limitations of this method call for the development of improved techniques.

An ideal male contraceptive approach should have minimally invasive drug delivery system with a one-time injection, long-term effectiveness with negligible side-effects and the option of reversal.

“To achieve these goals, a novel male contraceptive approach of Reversible Inhibition of Sperm under Guidance (RISUG) has been developed, which has the potential to become for mass use as once injectable and reversible male contraceptive method. Significant features of this method include localized injection and no detectable interaction with other body parts unlike the hormonal injectable contraceptives,” the study said.

NATIONAL: AGRICULTURE / VEGETABLES : ICAR-Indian Institute of Vegetable Research (IIVR) helps Grow Multiple Vegetables in One Plant

 Imagine planting one plant and getting multiple vegetables from it for your kitchen needs.

Scientists at ICAR-Indian Institute of Vegetable Research (IIVR), Varanasi are now working on a new single plant that will yield three vegetables simultaneously- brinjal, tomato and chilli.

The new plant is yet to be named.

The scientists had earlier developed ‘Pomato’ that yields potatoes and tomatoes on a single plant and ‘Brimato’ that yields brinjal and tomatoes together.

Using the grafting technique, the scientists at ICAR-IIVR, first developed ‘Pomato’.

Under the guidance of IIVR director Dr T.K. Behera, Dr Anant Bahadur, principal scientist (vegetable) and head division of crop production at ICAR-IIVR, Varanasi is now working on developing this unique single plant to yield three veggies.

“The grafting of chilli and tomato plants has been done on the brinjal rootstock and the plant is growing well. We are quite hopeful that it will start yielding chilli, brinjal and tomatoes by the end of January 2024,” said Dr Bahadur.

He said that he would analyse the feasibility of its cultivation.

Speaking about ‘Pomato’, Dr Bahadur said, “Potato tubers were germinated. Then grafting of tomato plants was done on the germinated potato tubers. As per the need, the plant was irrigated from time to time. It grew well and bore tomatoes above ground and potatoes below the ground.”

‘Pomato’, as a single plate, yielded around three kg of tomatoes and around 1.25 kg of potatoes, he added.

Thereafter, in 2019, Dr Anant Bahadur with his team grafted both the brinjal and tomato hybrids on the Brinjal root stock tolerant to waterlogging and salinity.

In 2019, his team succeeded in getting the desired result. He said the ‘Brimato’ is capable of surviving in waterlogged conditions for four days, whereas a normal plant wilts and gets destroyed in such conditions within 24 hours.

In October, the plant was transplanted, and brinjals and tomatoes were harvested till March.

A single plant yields around 3 kg of tomatoes and 2.5 kgs of brinjals, said Dr Bahadur.

Dr Bahadur said, “The special plant, ‘Brimato’, yields tomatoes and brinjals. It can be grown in kitchen gardens, backyards and also in small fields.”

NATIONAL : SCIENCE & TECHNOLOGY / HEALTH & MEDICAL SERVICES: IIT Madras develops Steam-based method to Sterilise Medical Equipment

Researchers at the Indian Institute of Technology (IIT) Madras have developed a solar-thermal steam-based system that can help sterilise medical equipment in remote and rural areas, where access to electricity and water could be an issue.

The project, funded by the Department of Science and Technology, uses portable steam cylinders charged by renewable energy-based stations (like solar energy) that are placed strategically in rural areas for power generation, steam generation and other uses.

The team also designed special sterilisation chambers to utilise such portably stored steam and effectively sterilise the tools.

“A portable steam storage canister can be a great contribution by facilitating minor medical interventions in the developing world by sterilising surgical instruments and combating infections in rural areas,” said Prof. Sathyan Subbiah, Department of Mechanical Engineering, IIT Madras, in a statement.

“The portable canister is developed with multi-layer insulation, which can retain useful heat of steam, generated via solar plants for longer duration thus making it a viable option to sterilise equipment in remote areas. The steam that is produced in the solar plant or any other means can be stored in the portable canister which can be transported to remote locations to carry out the sterilisation activities,” he added.

Safe sterilisation of surgical instruments and other medical tools are important aspects in the health care sector. It involves cleaning and disinfecting the previously-used contaminated surgical tools before subsequent use. Steam sterilisation is one of the best disinfecting methods.

Currently, doctors carry with them a set of sterilised tools, which limits the number of patients they can see at the camp.

The project was demonstrated during a medical camp at IIT Madras campus on October 14, and is all set for further trials, following which it is intended to be deployed in the field.

NATIONAL: AGRICULTURE : SCIENCE : Indian Institute of Science Education & Research (IISER) Bhopal team conducts Genome Sequencing of Indian Gooseberry Plant (Amla)

Researchers from the Indian Institute of Science Education and Research (IISER) Bhopal have for the first time unravelled the draft genome of the Indian gooseberry plant, popularly known as Amla.

Understanding the genetic composition of Amla can help us understand their origins, evolution, and how they create the biochemicals that are of medicinal value.

While Amla holds significant pharmaceutical and nutritional importance, its genetic composition has hitherto not been studied in detail.

“We analysed the genome and transcriptome of the amla plant using leaves from our campus. We employed advanced sequencing technologies, including 10x Genomics and Oxford Nanopore Technology (ONT) long-read sequencing, along with transcriptomic sequencing,” said lead researcher Dr Vineet Sharma, Associate Professor of Biological Sciences at IISER Bhopal, in a statement.

Amla is a well-known plant indigenous to South Asian countries and has been used in traditional Indian and Chinese medicine and home remedies for centuries.

The stone-fruit of the Amla tree is believed to have high Vitamin C content, in addition to being a rich source of various phytochemicals, minerals, and amino acids. Amla has been thought to be effective in treating conditions like unhealthy levels of fat, Type-2 diabetes, chronic gum diseases, symptomatic knee osteoarthritis, and more.

Apart from obtaining the draft genome structure of the Amla for the first time, the researchers also identified genes responsible for vitamin C biosynthesis and compared them with genes in other plants that bear vitamin C-rich fruits.

The team found that Amla’s exceptional antioxidant power comes from the adaptive evolution of certain genes involved in the production of antioxidants like vitamin C and flavonoids.

Amla’s abundant vitamin C content and the remarkable capacity of each tree to yield up to 100 kg of fruits make it superior to other vitamin C-rich fruits such as the West Indian cherry from Mexico and the camu camu fruit found in Brazil, Peru, Colombia, and Venezuela and makes it a perfect choice for switching from the synthetic to a natural source of Vitamin C.

According to the research team, the adaptive evolution of this plant could be one of the key reasons for its easy adaptation to various climatic zones and environmental conditions.

“The analysis of the whole genomic landscape of the Amla also helped us in understanding its evolutionary descent in comparison with 26 other plant species. It will also help in developing improved nutraceuticals, food, cosmetics, and pharmaceutical products, and for further horticultural and genomic studies,” Dr Sharma said.

The findings have been published recently in the open-access journal, Frontiers in Plant Science.
