He was also known for his development of anomaly of strong electrolytes and the ionization theory.
J C Ghosh's other important contributions include his extensive study of photocatalysts under the influence of polarised light and developments of Fischer–Tropsch reaction for the synthesis of hydrocarbons.
Dr.
Ghosh made contributions in the field of application of Differential Thermal Application (D.T.A) as tool to the systematic study of solid catalysts.
He also successfully guided research work on technical problems relating to the production from Indian raw materials of phosphatic fertilisers, ammonium sulphate, formaldehyde, potassium chlorate etc.
During his active career in building scientific research, technical education and industrial development, he was the Head of Department of Chemistry at Dacca University, the Director of Indian Institute of Science at Bangalore, the Director of Indian Institute of Technology, Kharagpur, the Vice Chancellor of Calcutta University, and the Director-general of Industries and Supplies, Government of India.
