Dr. Shampa Aich and her research group are focused in the field of metallurgical & materials science and engineering especially on (1) Smart materials (SMA/FMSMA), (2) Magnetic materials, (3) Bio-materials and (4) Surface modifications.Our contribution in those areas include, (i) Fabrication of NiTi shape memory alloy thin films by magnetron sputtering, (ii) Development of microstructure and magnetic properties of magnetic shape memory alloy ribbons in heusler family by rapid solidification (melt-spinning), (iii) Development of rare-earth-based as well as rare-earth free permanent magnets, (iv) Synthesis of wear resistant coating system of TiB (titanium monoboride) whiskers on titanium surfaces by solid state diffusion (Pack boriding), (v) Fabrication of macroporous but mechanically tough bio-scaffolds on the metal implant/stent surfaces, which can promote cell adhesion and proliferation on metallic implant and can perform controlled on-site drug release and photocatalytic sterilization. (vi) Deposition of a series of bilayers and multilayers coatings of Ti/TiB2, Ti/TiN, Cr/CrN and Ti/TiN/Cr/CrN on steel substrate by pulsed laser deposition (PLD) technique to improve the tribological properties and cutting efficiency of cutting tool, (vii) To determine the feasibility of growing inert silica shells around the metallic nanoparticles with the help of core-shell nanotechnology to render those nanoparticles stable by preventing their agglomeration and bio-degradation to improve their unique properties and potential biomedical applications.
Over the past years, our research has led to one US Patent ((U-3480), 2002) on “Integral Titanium Boride Coatings On Titanium Surfaces And Associated Methods” and 30 major publications in; Journal of applied physics, IEEE transactions on magnetics, Journal of magnetism & magnetic materials, Journal of alloys & compounds, Powder technology, Journal of materials science, Materials & manufacturing processes, Materials Letters, Surface Engineering and Metallurgical Transactions A.
