Research & Development


IIT Indore envisages the process of convergence of traditional disciplines as the key to accomplish the previously unimaginable. With this foresight, IIT Indore has been promoting multi-disciplinary research programme, focusing on basic and applied research, technology development and innovation. It is this vision that has helped the institute to do very well in all spheres of science, engineering and humanities and social sciences.

 

A core competency of IIT Indore is research driven academic programme as it forms a core component of the undergraduate and postgraduate teaching. At IIT Indore, we have consciously promulgated the idea of involving undergraduate students in forefront research projects. This led to the initiation of a formal undergraduate research scheme entitled, "Promotion of Research and Innovation for Undergraduate Students".

Latest @ R and D


Research at IIT Indore has been recognized at international level with active participation in several key international projects and several joint collaborations with research organizations in Japan, South Korea, Russian Federation, Portugal, France, Germany, USA, and many other countries. The institute has been successful in securing 82 externally sponsored research projects worth over Rs. 22 Crores.

 

IIT Indore recognizes that encouraging entrepreneurship for technology development, economic and social stability is need of the hour. The Innovation and Entrepreneurship Development Centre (IEDC) at IIT Indore was started with the same vision. IIT Indore students are in the process of having their own start-ups thus applying innovation into practicality for the benefit of all. In the coming years, IIT Indore will develop into a world class centre for higher academic and industrial research and innovation.


RESEARCH HIGHLIGHTS

STABILIZATION OF PHASES PRESENT IN PLASMA SPRAYED ALUMINA COATINGS

Stabilization of phases present in atmospheric plasma sprayed alumina coatings applied on steel substrates is possible by adding low quantity of Chromia to the alumina feedstock. Quantification of the different phases present in the coatings can be performed by subsequent use of Rietveld refinement method. Surface morphology, microhardness and wear behavior of the different coatings are also observed. Rietveld analyses performed on coatings ensure the stabilization of metastable phases present in the alumina coatings by chromia addition. Significant increase of the α-alumina and (AlxCr¬1-x)2O3 content is observed in alumina coatings with 4wt.% chromia content. This is supported by the improved hardness and wear resistant properties of the alumina coatings containing 4wt.% chromia in it. The minimum surface roughness of the coating is also observed for alumina coatings with 4wt.% chromia content among all the alumina coatings with different chromia content.

DISCOVERY OF “FANO SCATTERING”

We have discovered a new phenomenon, named as "Fano scattering", which is possible in nanomaterials in low-frequency regime (a few wavenumbers). Suitably fabricated silicon nanostructures (Si NSs) were used as the physical system to harvest low-frequency acoustic phonons which can interact with an intraband quasi-continuum to give rise to Fano interaction as observed through Raman spectroscopy. A size-dependent asymmetry in Raman line shapes at low-frequency for Si NSs has been observed. The experimental asymmetry of Raman line shape has been explained by a theoretical model that incorporates the quantum-confined phonons as well as the contribution of intraband quasi-continuum. Upto now there was no any direct way to extract information about non-radiative transitions which play very important role at nanoscale and define the characteristics of nanomaterial.
