    Abstract:

Applications: A novel method for producing improved ultra-high molecular weight polyethylene (UHMWPE) and its nanocomposites (UHMWPE-alumina (Al2O3)-Hydroxyapatite (HAp)-carbon nanotubes (CNTs)) as acetabular cup liner in total hip joint replacement (THR). Sterilization of implants before surgery is inevitable, thus only UV and only Gamma-irradiation techniques have been used for standard sterilization. The novelty of the present invention is to sequence them i.e., first UV-irradiation followed by gamma-irradiation. The optimum sterilizing time is crucial as it controls the mechanical strength and wear resistance of PE composites. So, a range of treatment time is provided below which sterilization is not effective and above which deterioration in properties occurred due to chain scission.
Advantages: The sequentially sterilized (first UV, then Gamma) UHMWPE and its composites can be a suitable implant material for any joint surgery, more preferably articulating cup liner in hip joint replacement surgery. The superior mechanical strength and wear resistance of sequentially sterilized UHMWPE cup liner can improve the lifespan (greater than 15 years) of hip joint surgery in young patients. The novel sterilization method can be implemented to biomedical devices for cells proliferation and growth However, different polymers (Polyether ether ketone, Polytetrafluorethylene, high density polyethylene etc.) used in biomedical devices can be sequentially sterilized to modulate the surface or bulk molecular arrangement with improved mechanical strength and wear resistance.

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.
