[2][3] 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.

[4][5] Dr. Ghosh made contributions in the field of the application of Differential Thermal Analysis (D.T.A) as a tool for the systematic study of solid catalysts.

[6] 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 the Department of Chemistry at Dacca University, the Director of the Indian Institute of Science at Bangalore, the Director of the Indian Institute of Technology, Kharagpur, the Vice Chancellor of Calcutta University, and the Director-general of Industries and Supplies, Government of India.

[citation needed] Jnan Chandra Ghosh was born in a Bengali Kayastha family in Giridih, Jharkhand, British India.

The Vice-Chancellor of Calcutta University, Sir Ashutosh Mukherjee invited Jnan Ghosh to join as a lecturer even before the results were published.

The Sir Tarak Nath Palit Scholarship and Premchand Raychand student of the year award enabled J C Ghosh to travel to England for his doctoral degree at University College of Science in London.

[citation needed] In 1921, J C Ghosh returned to India and joined the newly established Dacca University as professor and Head of the Department of Chemistry.

[13] Towards that goal, he led research work on technical problems relating to the production from Indian raw materials of phosphatic fertilisers, ammonium sulphate, formaldehyde, and potassium chlorate.

During this period, he also served as a member of the All India Council of Technical Education and there he felt the inadequacy of quality trained persons for large-scale industrial development.

He took part in all the stages of the preparation of the Second Five Year Plan and had a large share in working out proposals for the expansion of facilities for technical education at various levels.
