Abstract:
The present disclosure relates to a process for preparing the boron based nano- sheets. The process comprises a step-by-step chemical recipe that integrates the phenomenon of intercalation with ultrasonication. The chemical recipe includes a reaction of MgB 2 crystals with aqueous H 2 SO 4 which results in selective removal of Mg ions from parent crystals making it amenable for intercalation in presence tetramethylammonium hydroxide (TMAOH). The intercalation process leads to expansion of crystal by increase in the inter-layer gallery space from 3.5A° in parent MgB 2 to 4.7A° in the expanded crystals. Subsequent ultrasonication of these expanded crystals exfoliates the crystals with higher yields, into few-layer-thick nanostructures which resemble morphology of accordions. For the first time, the present disclosure is reporting such accordion-like nano-sheets derived from MgB 2 .

THE VISION
THE MISSION
ABOUT I-STEM
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.
