The second technical session was
conducted by B.R. Chakraborty, NPL
New Delhi. His presentation, "Fabrication Techniques of Nanomaterials and Its Application," discussed
various top-down and bottom-up
techniques related to synthesis of
nanomaterials. He also discussed different characterization techniques
for nanomaterials.
Session three of the second day
was by Prof. Pradip Kumar Kalita from
Rajiv Gandhi University, Arunachal
Pradesh. His talk was "Optoelectronic Properties and Applications of
Thin Films," in which discussed the
history and different properties of
thin films.
The fourth, and final, session
was an interactive workshop among
the participants and Pramanik,
Chakraborty and Kalita.

Day Three
The first session of the third day of
technical talks was a continuation of
Kalita's presentation, "Optoelectronic
Applications of Thin Films," in which
he discussed different techniques for
thin film preparation, their characterization, and photocatalytic properties.
The second session was conducted
by Prof. Prodeep Phukan, Gauhati
University, "Modified Cobalt Ferrite
Nanoparticles as Magnetic Material."
He discussed the synthesis of magnetic nanoparticles and their characterization. Prof. Sunandan Boruah
from Assam Don Bosco University
gave the third talk of the day, "Synthesis, Characterization and Applications
of Nanomaterials." Dr. Pranjal Saikia,
Gauhati University concluded the sessions on day three with "Catalytic Properties of Nanomaterials."
