Microstructural engineering of metallic materials towards achieving exceptional mechanical performance
It is well known that the traditional paradigm of the materials science tetrahedron depicts the inter-dependent relationship among the structure, properties, processing, and performance of a material. The demand for high performance structural materials for real world applications has undoubtedly driven scientific efforts for the past few decades due to stringent regulations on efficiency and emissions.
Micromechanics of the materials group
Increasing degree of miniatursation of structures and devices has thrown open new observations in a material's response to different loading environments that are starkly different from that of the bulk. Thin films, nanostructures, MEMS and several other systems belong to this category. The 'smaller is stronger' and 'inverse Hall-Petch effect' are typical size effects that occur when the external surface or internal interface shrinks in size. Brittle materials become more damage tolerant while ductile materials tend to become increasingly brittle at small dimensions.
Sweet News For Diabetics
India is infamously called the ‘diabetes capital of the world’. With over 40 million diabetics in the country, we have a distinction of having the highest number of diabetics for any country. This has huge implications on the country’s healthcare, forcing doctors, scientists and citizens to work together to manage and remediate this condition. Now, researchers at the Indian Institute of Technology Bombay (IIT Bombay) have some sweet news for diabetics. They have developed a polymer based bioartificial pancreas that can be implanted inside the body, thus helping in managing diabetes.

A Computational Model of the Bladder
We have all felt it—the uncomfortable feeling in our nether regions that has us heading to the nearest washroom to empty our bladder. While many of us can hold it until we reach a toilet, those with urinary incontinence, or the inability to prevent the leakage of urine from the bladder, face a severe social and hygiene issue. This condition can be caused by a variety of factors, such as urinary tract infections, kidney stones or neurological disorders.
Accurate estimation of manufacturing variations can improve circuit performance New experimentally validated model accounts for manufacturing process variations while designing ultra-dense electronic circuits.
Silicon-based electronic circuits are continuously getting smaller. The Taiwanese manufacturer
TSMC currently makes chips with the smallest feature of the circuit measuring just 7
nanometers, with millions of such components packed on a single chip. The process of
manufacturing such ultra-dense circuits is complex. Despite world-class control, there are tiny
fluctuations in the nanoscale dimensions. Thus, each transistor is slightly different from another
across chips and even on the same chip. A circuit designer must account for such variations to
Chemistry of phosphorus compounds: Options are endless

Dynamics in crowded and active medium
We have been involved in understanding the mechanism of transport in crowded and active medium. For this, we build statistical mechanical models and solve it either analytically or on a computer, when complicacy of the problem does not allow exact analytical solutions. Availability of single molecule data also makes it possible to compare our results with experiments. A realistic example would be biological cell where presence of cell organelles makes it highly crowded.
Printable and flexible transparent conducting electrodes and display devices
Touch screens have become the ubiquitous interface for controlling contemporary electronic devices and incorporated into almost all the new technologies starting from smart phones, computers, flat panel televisions to personal gadgets and household appliances. One of the key components of touch screen is a transparent conducting electrode (TCE) which is optically transparent and electronically conductive. TCEs are also the backbone of optoelectronic devices eg. organic light emitting devices (OLEDs), photovoltaics (PVs), liquid crystal devices (LCDs) electro chromical devices (ECDs) etc.
Studying chemical reactions using transition state modeling
Our research focuses on chemical reactivity and catalysis. When two molecules react to form product(s), there are different likely pathways that one can think of. Energies of various intermediates and transition states connecting such intermediates involved in the reaction has an enormous effect on the pathway a reaction would proceed through. We employ ab initio and density functional theory computational methods to identify the nature of intermediates and transition states involved in catalytic reactions.
