    Basic Information

Technology developed: 2D Nanolayered Tungsten & Molybdenum Disulphides (TP19762335965)
Category: Technology Service/Know how
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. R Vijay International Advanced Research Centre for Powder Metallurgy and New Materials Centre for Nanomaterials Scientist F
Technical Application Area: Manufacturing
If 'Other', please specify:
Automotive, Aerospace
Please give more details of new technical application area:
2D nanosheet like structure in sulphides of transition metals like tungsten and molybdenum have shown wide range of attractive properties, which can be harnessed for various applications as catalyst or lubricant. However, the absence of commercially viable routes for their synthesis in bulk quantity and reproducible quality has been a major issue hindering their commercial exploitation. Recently, a novel technique has been developed by ARCI to generate such 2D structure in WS2 and MoS2. The process offers unique control capabilities to synthesize tailor-made 2D nanolayered structure in these sulphides in bulk amount.

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.
