Our faculty recent work has been featured in Hindu Business line as well as IITM News Letter
Researchers at IIT-Madras have synthesised a tough, ceramic material that can conduct electricity and heat, which could possibly be used for storing hydrogen too.
A crystal structure found in certain materials called ‘MAB Phase’ gives them special properties such as high strength. In this M stands for a transition metal, like zirconium, molybdenum or titanium; A for either aluminium or silicon; and B for Boron.
Prof Somnath Bhattacharyya of the Department of Metallurgical and Materials Engineering and his team have developed a MAB phase layered ceramic — using tungsten, aluminium and boron — called WAlB. While WAlB is not a new material, known to be useful in nuclear shielding, Bhattacharyya and his team have developed a new process for making it, in a medium of molten salt. The resultant material is also of very high purity — about 98 per cent.
Bhattacharyya explained to Quantum that the material is a layered ceramic, with 2D layers of tungsten and boron, with aluminium in between. WAlB has been synthesised earlier at temperatures of 1400o C, but Bhattacharyya could do it at 800oC, at ambient pressure.
Calling the work a “breakthrough”, Dr Varun Natu, scientist at National Chemical Laboratory, Pune, observes that synthesising WAlB has traditionally proven difficult, resulting in only small crystals with low yield. However, “Bhattacharyya’s team has demonstrated not only large-scale synthesis of WAlB but also a method that uses a molten salt as a sheath. This approach significantly reduces production costs and simplifies potential future scaling, making WAlB a much more viable candidate for real-world applications.”
This material could be used as a semiconductor or for hydrogen storage, he said. Asked if the industry could take up production of this MAB at scale, Bhattacharyya said it was possible, as repeated synthesis by his students got the same, high purity material.

IIT Madras and IIT Kanpur research work on “Ways to recycle waste material from iron ore mining" covered in Business Standard
Researchers at the Indian Institutes of Technology Madras and Kanpur have developed a process to convert waste produced from iron ore mining into an environment-friendly material that can be reused by industry.
The researchers collaborated with NMDC and JSW Steel to transform slime into iron-rich materials suitable for blast furnace charging through a microwave-assisted beneficiation process. The process is economical as the microwave selectively interacts with iron oxides or carbon mix, leaving out other impurities (like silica, alumina, phosphorus oxides) while also rapidly heating the material compared to conventional routes, saving a significant amount of energy and emissions.
This project is of importance to India as while processing iron ore, particles smaller than 0.15 mm generated and are discarded as waste known as slime. Slime generated during mining is about 20-25 per cent of the total iron ore feed and it is dumped between iron-bearing mountain ranges.
Over years of mining, this has resulted in huge slime ponds holding several million tonnes of locked iron content. The slime, besides lying unproductively, may damage the land and environment. Currently, these slimes are partly exported as low-grade iron ore.
"This project has led to the creation of a lab with high-temperature facilities at IIT Madras, which was renamed as Centre for Pyrometallurgy, comprising equipment and facilities created by IMPRINT INDIA funds to perform lab-scale investigations of high-temperature processes involving reduction roasting or smelting," said Ajay Kumar Shukla, associate professor and head, centre for pyrometallurgy, department of metallurgical and materials engineering, IIT Madras.
"The project resulted in a significant breakthrough towards the development of technology to process lean quality fine iron ores on a large scale in a cost-effective and environmentally friendly manner," said Anish Upadhyaya, Department of Materials Science and Engineering, IIT Kanpur.
IITs Madras and Kanpur undertook a project under IMPRINT INDIA (Impacting Research Innovation and Technology), an initiative of the union education ministry. The researchers also published their findings in a reputed peer-reviewed journal with research scholars Soumya Ranjan Mohanty and Sunil Yadav.
"This work demonstrates an innovative, cost-effective, and energy-efficient way which may be upscaled further towards the development of a technology to beneficiate the lean quality iron ores," said Vibuti Roshan, deputy general manager (research and development) at NMDC.

MME Department faculty research work on turning bauxite residue into resource covered in Hindu Business line.
Presently, the cement industry consumes only 2-3 per cent of the bauxite residue produced every year, leaving the bulk to be treated as hazardous waste.
Bauxite residue, also known as Red Mud, contains toxic heavy metals such as arsenic, lead, cadmium, chromium, vanadium and mercury. Its high alkalinity makes it extremely corrosive and damaging to soil and life forms — it can be harmful if ingested or inhaled — posing a significant threat to the environment.
Recent efforts, particularly in Europe, in comprehensive bauxite residue utilisation involve multi-stage processes that yiels multiple products. The current research from the IIT team (Prof. Ranjit Bauri’s group in MME department) not only opens up opportunities for the disposal of bauxite residue but also creates opportunities for its utilisation in the recovery of valuable materials, thereby promoting sustainability and a circular economy. Additionally, it serves as a potential alternative source of materials for energy harvesting and storage.

IIT Madras develops 3D-Printed Face Implants for patients suffering from Black Fungus along with Zoriox Innovation Labs
Indian Institute of Technology Madras (IIT Madras) researchers have developed 3D-printed face implants for patients suffering from Black Fungus, which has been reported in COVID-19 patients as well as those with uncontrolled diabetes, HIV/AIDS and other medical conditions. Around 50 implants have already been done on patients from economically-weaker sections.
The Institute has partnered with ZorioX Innovation labs, a start-up founded by Dental Surgeons in Chennai, to implement this initiative, which is based metal 3D Printing or additive manufacturing.
The outbreak of black fungus disease, also known as ‘Mucormycosis’, has been a cause of great concern in India. One of the most devastating effects of this disease is the loss of facial features, which can have a profound impact on the patient’s mental and emotional well-being.
Therefore, the reconstruction of faces lost due to black fungus is the need of the hour. Reports suggest that about 60,000 mucormycosis cases have been registered in India post-COVID.
The fungus responsible for mucormycosis can invade the tissues of the face, causing necrosis and disfigurement. In severe cases, patients may lose their nose, eyes, or even their entire face. Furthermore, the loss of vital organs can affect a patient's ability to breathe, eat, and communicate, making it difficult to perform everyday activities.
Reconstructive surgery is a viable solution for patients who have lost their facial features due to black fungus disease. These procedures involve the reconstruction of the nose, eyes, and other facial structures using a variety of techniques, such as skin grafts, tissue expansion, and microvascular surgery. These procedures can help restore the patient's appearance and function, allowing them to lead a more normal life.
However, patient-specific implants and the procedures are expensive, rendering them inaccessible for people from weaker sections.
