Magnetic materials for multifunctional applications: Magnetic refrigeration to spintronics

Magnetic alloys consisting of transition elements, especially the ones known as Heusler alloys are in the limelight because of the multifunctional properties they exhibit. These include ferromagnetic shape memory effect, giant magnetocaloric effect (MCE), giant exchange bias (EB), large anomalous Hall effect and half metallic ferromagnetism (HMF).

Fly ash utilisation in haul road construction in open cast coal mines by using polymeric fly ash composite

Haul roads being the life lines of mines are an important factor for smooth and continuous working of mine. Traditional ways of building haul roads lead to frequent ruptures and breakdown in these roads due to erosion of material, water slurry formation, huge dust generation, etc. This leads to production halts and productivity decline and ultimately economic losses.

Development of engineering ceramics for variety of advanced structural applications via microstructural engineering using innovative processing routes

In addition to the more conventional applications, such as refractory linings of steel-making furnaces / ladles and pressurised chemical vessels,engineering ceramics, owing to their high stiffness, excellent thermal stability, relatively low density and corrosion resistance have a variety of applications as advanced structural materials in cutting tools, armor, wear resistant parts, etc.

RoVeR: Remotely operated vehicle for army

A remotely operated ground vehicle (RoVeR) was designed and developed for use in counter terrorism and counter-insurgency operations by the Indian Army.The RoVeR can traverse difficult terrain, extreme slopes, inspect suspicious objects (e.g. improvised explosive devices) with a robotic arm (even when hidden under a bridge) and give visual feedback to an operator away at a safe distance of 0.5 km.

Engineering surfaces for self cleaning and reducing drag

Understanding impact dynamics of bouncing and non-bouncing droplets on hydrophobic and superhydrophobic surfaces is useful in several technical applications. These surfaces exhibit low wettability and this property may be leveraged in the applications such as pesticide spray coating, drag reduction, anti-snow adhesion surfaces, self cleaning surfaces, and surface cooling via spray evaporative cooling and on spatially varying wettability surfaces.The effect of pitch of the pillars and impact velocity are studied for the impact dynamics of a microliter

Tuning colloidal deposits by evaporating sessile droplets

On a fine morning, if you take a tiny droplet of coffee and dry it on a table top, a ring like pattern of dried coffee particles forms. This problem is known as coffee ring problem and the mechanism of the ring formation was firstproposed by Deegan et al, 1997. This seems to be an efficient way pattern micro or nanoparticles on solid surfaces. For example, in bioassays and ink-jet printing. In our lab, we have established new ways to self-assemble particles by evaporating sessile droplets.

Emission reduction technologies in diesel engines

India is planning to implement BS (Bharat Stage) VI emission norms by the year 2020. With this, advanced technologies are necessary to reduce emissions in IC engines by a large percentage. Several technologies have been tried to reduce emissions in our lab; some of them are:
Ultra-cooled EGR (UCEGR)
Exhaust gas is cooled, using a counter flow heat exchanger, to less than 5 o C and recirculated back to the engine.
Oxidised EGR (OEGR)

Numerical modeling of lifted flame

Lifted flame is a very complicated turbulence flame; difficult to model thelift-off height. Conditional moment closure (CMC) is an advanced combustion model but it too cannot predict the lift-off height accurately. We have successfully proposed a new model based on extinction criteria (CMCE). CMCE has predicted lift-off heights accurately for a wide range of jet velocities and coflow temperatures in a lesser CPU time. This proposed model helps in modeling gas turbine combustion accurately.

Self cleaning coating

This is the age of smart coatings – which means the coating will act its designated function as per the pre-defined stimulus. Multi-storey glass buildings, ACP facades, solar panels, sophisticated furniture, etc. all gather dust or stains which spoil them. In order to make them stain / dust free, it is advisable to provide the self-cleaning ability.
