Earlier, often in collaboration with other faculty, we have worked on wide range of areas such as (i) understanding the mechanism Chemical Mechanical Planarization
(CMP) used in semiconductor industries and to find solutions to some of the
existing issues, (ii) on air pollution monitoring and control, (iii) microwave melting of metals, (iv) drying of cocoa beans,(v) comparison of fixed vs manual tracking in solar PV (vi) purification of TCE by distillation (vii) pressure swing adsorption (PSA) for oxygen concentration.
