Starting with a brief description of what bioglass is about, he went to its further applications and development in different fields of engineering. Developed by Larry L. Hench in late 60', Bioglass is specifically composed of silica, calcium oxide, sodium oxide and phosphorus pentoxide. It has several applications in the domains of
- Bone regeneration
- Dental adhesives
- Implant dentistry
- Air abrasion
Further, he touched different aspects of opportunities in bioceramic materials in orthopaedic, dental and tissue culture. Prof. Ray explained in detail about which all Biomolecules constitute the bioglass and how the material is being formed.
Next up was the topic of hemocompatibility analysed through a graph of percentage hemolysis vs absorbance followed by a brief idea of in vitro calcification.
Summing up, he concluded touching the point stating

- Biomolecular glass contain heterogeneously distributed nanomoids
The final session was taken up by Prof. Debrupa Lahiri, from the department of biomaterials and multiscale mechanics lab, Department of Metallurgical and Materials Engineering at IIT Roorkee. The session was about surface-modified metallic orthopaedic Implant for sustained drug release.
She started with the topic of orthopaedic implants and the consequences of infections. So, to serve safety for a more extended period without any rejection, a metallic Implant offers
- Excellent bio-compatibility (non-toxic)
- High corrosion resistance
- Suitable mechanical properties
- High wear resistance
Bio-ceramics provides several applications such as
- Bone-scaffold and bone-filler

The knowledge imparted by them to the budding inquisitive minds makes them perceive a lot, thereby building a desire in them to take the technology ahead in several applications and do welfare to the society.
Team MM reached out to one of the coordinator of the event and the President of NITR-ICS, Ekta Kumari, for knowing about her stance on the implementation of Obmodtea.
It all started when one of the mentors of our chapter proposed us to include the InCerS chapter in this webinar for a better reach and platform. And with the support of the convenor of the event Prof Sudip Dasgupta, HoD of Ceramic Engineering Prof. Debasish Sarkar, and the Faculty advisor of our InCerS chapter Prof. S K Pratihar, we were able to implement it properly."
Webinars and online sessions have become way too familiar these days pertaining to the problems faced due to the pandemic. Even in online sessions and webinars, a lot of planning and management has to be done to ensure that the event is being conducted smoothly without much of connectivity issues. This is what Ekta Kumari had to say,
Management- A captain or leader is as good as his/her team. I am extremely thankful to the executive body of the 20-21 session for showing so much dedication and professionalism towards this chapter. As I am busy with my research intern in tata steel, the core team took the whole responsibility to manage and coordinate the works among themselves. In a brief period, we managed to contact more than ten colleges across India, and around 200+ participants registered for the webinar. As demanded by some speakers the broadcasting was kept private, so the team took the responsibility of sending the mail of webinar link to each and everyone (200 participants nearly )at least 12 hours before the event for consecutive five days. And at the same time, we tried to respond to every query of participants through mail and call from our side.
Team MM appreciates ICS and Department of Ceramic Engineering for making Obmodtea happen and ensure that the event is carried on smoothly.
