Innovation does not come from the information or knowledge; it arises from the wisdom gathered from one concept and applied to an entirely unrelated problem. Material science offers that central spot where one can work in interdisciplinary research fields such as metallurgy, mechanical, electronics, chemical, biology and computer sciences to drive the technology forward.

Welcome to Material Science

Start by doing what's necessary; then do what's possible; and suddenly you are doing the impossible.

The CeramicWorks Lab

firework Why did we name our lab "CeramicWorks"?

From an early age, Diwali was the most awaited festival for me. Light, color, food, festival and fireworks. When I saw the fireworks in US on the occasion of 4th July (Independance Day), I was mesmerized: what patterns! what precision in timing! A science of alchemy which was nothing short of magic. The bright colors in the dark sky, manifesting joy, exuberance, and celebration. In our research, we want to achieve the technological excellence with synthesis and processing of novel materials that will capture our imagination of a vibrant future.

Ceramics is that material with infinite possibilities. Ceramics exhibit wide range of properties, because of their ability to form ionic and covalent bonds and configure themselves in varieties of crystal structures. And that's where their strength lie: they are everywhere - in the porcelain bowls, protection vests, space-shuttles, lasers, sensors, energy harvesters, solar cells, energy storage devices (batteries, super-capacitors), fuel-cells, refractories, bio-ceramics, electronics, jewelries, … you name it!

One of my teachers once described ceramics as "Ceramics are the materials of future and they will remain so forever." The reason being the permutations and combinations of possibility for coming up with new ceramic compounds is beyond imaginations and so are their applications. But, let us not limit ourselves to ceramics only; let's use all the materials available: ceramics, metals, polymers, composites, metamaterials, all of them realize a world of new material, new technologies, new possibilities.


firework Any reliable technology stands on sound scientific foundation. Being an academic research lab, scientific understanding comes first. Our research group focuses on three major field of researchs: Composites, Field assisted processing, and Machine learning. While appearing disconnected at first sight, they are pieces of the same jigsaw puzzle, commonly known as "Material's Tetrahedron". This tetrahedron emphasizes on four independant pillars in developing technologies that we can depend on: Structure, Processing, Properties and Performance.

Crystal structure and processing technique determine the final properties of materials. But as learn from Ashby's Material selection Maps, there are always trade-off in properties. For example, hard materials have limited ductility. To overcome this natural challenge, we design composites of complementary materials and take advantage of field assisted processing to achieve desired performance. Machine Leaning and FEM (finite element method, YouTube Video) are used as tools to understand and simulate the corelations among the corners of the Tetrahedron.


firework Ashby’s maps highlights the need for composite designs where materials of different properties (often contrasting) are stitched together to provide superior properties. Properties that no single material exhibit, kind of Meta-material. Nature, being the greatest designer/architecture has done it over and over again, giving rise to a new field of study "Bio-inspired designs."

A very simple example of a composite, human bones , is a composite of hard mineralized tissue (cortical) and soft organic elastic fibers (collagen). The hardened matrix, formed by Calcium Hydroxylapatite, grows into an open-lattice structure that allows blood vessels. This unique design and composition allows bones to be hard and fracture resistant while being light-weight. Additionally, it is also functionally graded material with hard cortical bones on the surface and spongy Trabecular bone inside. An idea that has been adopted in TMT ( Thermo Mechanically Treated) steel bars, used to reinforce concrete (another example of popular composite). We design the structure of composites made up of metal-ceramic-polymers for armor, functionally graded materials, thermal barrier coating and shock absorption applications.

Field Assisted Processing

Ceramic parts are primarily fabricated by sintering. Sintering is a process in which powders of desired material are first compacted into desired shape and then fired to a high temperature. High temperature facilitates the diffusion of constituent particles into a solid dense mass. Sintering, in the form of pottery, is one of the oldest invention of human civilization. However, the process has changed little until a few decades ago when our scientific understanding of sintering mechanisms improved. Researcher showed that pressure, rapid heating and microwave heating can not only shorten the processing time but also improved the properties of fabricated material. The field assisted sintering (also known as Flash Sintering) is the latest addition to the list, in which we apply electric field directly to the ceramics (at relatively lower furnace temperature).

In the figure accentuates the role external fields play in reducing the energy consumption and time required for processing, by introducing a new path for duffusion)create non-equilibium crystal structural changes that give rise to novel properties, even in traditional ceramics. For a typical case of 3 mol% yttria stabilized zirconia, as we move from convention sintering to pressure assisted (hot press), Microwave (MW), Spark plasma sintering (SPS) to flash sintering, the sintering temperature dropped from 1500 C to 800 C. The right most figure shows that as we apply higher and higher electric field (DC voltage)the sintering temperature drops and densification rate enhances.

Our hypothesis is that these externally applied fields (shown in red)create non-equilibium crystal structural changes that give rise to novel properties, even in traditional ceramics. play in reducing the energy consumption and time required for processing . We are working to come up with a unifying theory which can explain the field-matter interactions, and to harness this understanding to thermal barrier coatins (TBC), functional ceramics, and storage devices (batteries).

Machine Learning

firework There isn't any active field of research that is not utilizing Machine learning (ML) or Artificial Intelligence (AI) to unravel the emperical relationships between the causes and the effects. In material science, ML is finding applications in understanding phase evolutions for complicated systems, predicting material properties of new alloy compositions, ML aided molecular dynamic simulations, corelating properties to the processing history, Microstructure analysis, to name a few (link).

In our lab, we are using Neural Networks, Random Forest and UNET along with Finite Elemental Method (FEM) simulation to formulate the processing parameters and intelligent designs of composites. Our group is currently working on grain boundary detection , orientation of pearlitic lamellae, intelligent phase identification, peak fitting of X-ray diffractions.


Science is the systematic study of natural phenomena, while technology uses scientific discoveries to create device and equipment to solve a probem or further our understandings. In simpler words, technology helps in scientific discoveries and good science leads to development of new technologies. We, being a Technological institute, are committed to design products and processes that can serve the society well. Accordingly, we work on the projects involving technological applications of the Sciences we are involved in.

Oxygen Concentrator

firework During the Pandemic, we realized the big chasm between theories being taught in the classes and technologies being developed. With all scientific prowess we struggled to save lives. There were urgent need for PPE kits, Ventilators, Oxygen concentrators, vaccines. I was involved in two of these projects: PPE Kits and Oxygen concentrator. The working principle of an oxygen concentrator is rather simple: zeolite under high pressure selectively absorps Nitrogen on its surface. All one needs to do is to have two vessels containing Zeolite and use pressure swing adsorption (PSA) with the help of timed solenoid valves get pure oxygen from one vessel while the other one gets purged. This process reverses in the second half of the cycle and it continues.

firework Transforming this principle into technology turned out to be a challengin task, but with the help of IIT community, specially our technical staffs at IITK: Vijay Yadav, Om Prakash, Anil Jha and our own alumni from RevRefineries, we were able to achieve 90-93% pure oxygen at the flow rate of 10 LPM (Litre per minute). I am sharing a post of Startup Innovation and Incubation center at IIT Kanpur (SIIC), with Prof. Amitabha Bandyopadhyay (BSBE) and Prof. Suman Saurabh (IME). .

Thermal Barrier Coating

firework The power efficiency of a turbine engine and jet engine is limited by the temperature these structures could withstand without softening. Depending on the application, operation temperatures can exceed 700 ºC. Beyond these temperatures, refractory metal-alloys start oxidizing and softening, resulting in quick degradation. Ceramics, on the other hand, are resistant to oxidation, corrosion and wear, as well as withstand very higher temperatures. However, they are brittle in nature and can undergo catastrophic failure without warning. So, naturally a composite materials are developed in which the high temperature Ni-super alloys are coated with a thin layer of ceramics, called thermal barrier coating, TBC (relevant article).This coating serves two purposes: it protects them from oxidation, and it can sustain an appreciable temperature gradient across a relatively thin layer of ceramic (100 μm to 2 mm) which allows the engine to operate at a much higher temperature, thus achieving a higher efficiency as per the Carnot cycle.

While the idea of TBC is simple, processing isn't. And that is because of the processing temperatures for metals and ceramics are different and the wettibility of ceramics on metals is poor, meaning they don't want to stick to each other and result in poor interfacial strength. With microwaves (electromagnetic fields), electric fields and magnetic fields we have seen improved interfaces and mechanical adherence and some unexpected results.

Shock absorber armors

firework Taking a leaf out of Nature's design handbook, the research group Prof. Ortiz (MIT) and her collaborators have used the idea of Exoskeletons of insects, shells of invertebrates, and scales of fishes to conceptualize flexible Bio-ceramic armors. In a ground breaking finding, published in Nature Communication, Prof. Ling Li's group (VT, Blacksburgh) mimicked Chiton's scaled exterior mineralized scales arrayed on the soft underlying layer. The inter scale spacing was design to give flexibility for easy manoeuvring. We are developing composites of metal-ceramics-polymers to develop shock absorbing designs.

Gas sensor

firework While factories and laboratories are essential for Technological advances, they also generate various toxic gases like NO2, CO, and Volatile Oxide Components (VOCs such as acetone and ethanol) pose a serious threat to our health and wellbeing. This situation has compelled us to think of sensors that can monitor the presence of such gases in real-time. While some sensors are already in use, we need to develop novel synthesis routes and new sensing materials, which can be then integrated together to achieve high accuracy and precision. Metal oxide semiconductors (MOS) in nanostructure form have the potential of becoming a compelling alternative to existing sensors owing to their high surface-to-volume ratio, high sensitivity towards toxic gases, and ease of synthesis, while being economically viable. We work on Hydrothermally grown oxides and doped oxides to improve their sensing properties based on morphological changes.

ML on Microstructure

firework For material processing, Microstructures always play crucial role in determining the properties. So far it has been done by metallurgist with tons of experience. ML is the new expert which "quickly" learn from examples and make intelligient predictions. We are working on several ML project related to microstructures: grain boundary detection for grain size measurements, phase quantification in multiphased alloys, orientation of lamellar pearlite in hypo-eutectoid steels and X-Ray Diffraction peak fittings. As we improve our understanding, we will expand into different fields of Material Science. seen many microand
