The present invention provides synthesis of a low cost bipolar membrane having superior performance by functionalization of base polymers of glass transition, Tg < room temperature and possessing good chemical, mechanical and thermal stability. Catalyst (2, 6) Pyridine dicarboxylic acid also called Dipicolinic acid, (DPA) layer is used for water dissociation. At normal pH (~7.0) DPA acts as deprotonated dicarboxylic acids anions (-COO-1) and its presence at interface, water dissociation potential at 100 mA·cm-2 gets reduced to 2.345 V from 2.65 V, while a commercial (FBM) BPM showed potential of 1.972 V. Application of nylon based woven fabric reduced the overall cost of BPM compared to PEEK based woven fabric as reinforcing material. DPA deposition increased current efficiency (η) of BPM electrodialysis from 59 to 64 % (while the same η with Fumatech BPM is 81% and the energy consumption (E) got reduced from 11.56 to 10.26 kWh·kg-1.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
