to realize high-performance deep-blue emitting materials for OLEDs. Finally, he concluded with the dark
triplet exciton harvesting channel and their impact on EQE and CIE color coordinates.

Heusler alloy thin films for spintronics applications
Prof. Srinath S, University of Hyderabad, Hyderabad, August 17
th
Prof. Srinath S, Department of Physics, University of Hyderabad, delivered an
excellent lecture on Heusler Alloy Thin Films for Spintronics applications. Prof.
Srinath has indulged in Heusler alloys, types, and various applications. In the talk,
after a brief introduction to spintronics, the speaker discussed some exciting ideas
about transport and magnetic magneto-transport results. Then, he focused his
discussion on Cobalt-based Heusler alloys which, attracted great interest due to their
high spin polarization, high Curie temperature, and high saturation magnetization.

Smart functional polymeric materials for energy and biomedical applications
Dr. S. Vengatesan, Central Electrochemical Research Institute, Karaikudi, September 30
th
Dr. S Vengatesan, Senior scientist, Electro-Chemical Process Engineering Division
CSIR-CECRI Karaikudi, focused on the polymer composite, which finds unique

applications in automotive, aerospace, military, medical and sports fields., especially
tissue engineering. Energy and medical fields are considered the top-most sectors
where enormous challenges are daunting in front of humanity in the 21st century.
Hydrogen, an eco-friendly and zero-emission fuel, is forecasted as a promising

renewable energy source in the automotive sector. He spoke about water electrolysis
as an efficient electrochemical process that can produce pure hydrogen from water. He focused on

developing cheaper hydrocarbon-based membranes with suitable ionic conductivity and stability. He also
suggested the role of the different polymers and their compositions on the physio-chemical properties of
the membranes.
Further, he showed that metal-based implants widely used in tissue engineering are heavy-weight and

cannot satisfy tissue restoration or regeneration requirements. The replacement of damaged tissues and
bones is inevitable by employing polymer composite scaffolds/implants since the polymers have elastic
mechanical properties. The session gave ideas on developing bio-degradable polymers as
scaffolds/fibrous materials with good biocompatibility, cytocompatibility, and antibacterial properties.

Advanced materials for structural applications
Dr. Hari Krishna Koduru, Bulgarian Academy of Sciences, Bulgaria, October 29
th
Dr. Hari Krishna Koduru from the Bulgarian Academy of Sciences, Bulgaria, Sofia,
spoke about the "advanced materials for structural applications." His talk was based
on Metamaterials. These materials are alleviated the classical limitations of optics and
led to exotic applications such as negative refraction, sub-wavelength resolution
imaging, invisibility devices, and perfect absorbers. Furthermore, he showed that the
enhancement of spontaneous emission is a dynamic and challenging fundamental
quantum phenomenon in optics. In a nutshell, it opens new avenues for a spectrum of
