DESCRIPTION :
ARTIFICIAL
PHOTOSYNTHESIS:
The
major focus is on designing the heterostructured photocatalysts with desired
morphologies and size as to exploit the advantages associated with
nanomaterials (such as quantum confinement effects, surface area),
hetero-interface with appropriate energetics and layered structure of
semiconductors for efficient solar H2 generation and CO2 and
N2 reduction to fuels. Also underpinning the surface chemistry /
electrochemistry / band gap engineering involved in photo-catalysis.

NOVEL
DIRECT WHITE LIGHT EMITTING MATERIALS & DEVICES:
The white LEDs
available as of today, typically consists of a blue LED and one or more
phosphors to convert part of the blue light to longer wavelengths and suffers
from low spectral power distribution in the red region and dampening emission
intensity. In addition, these are synthesized by sophisticated high vacuum
methods, which are expensive methods. We are working on developing the
novel direct white materials that eliminate the phosphors use and can
exhibit broad emission over the entire visible spectral range (400-800 nm)
under ambient conditions and underpinning the photo-physics in these processes.
We have recently discovered the formation of a stable complex under
ambient conditions, extending the present understanding of molecular
interactions, and exhibiting the unusually enhanced broad emission over the
entire visible spectral range (Inorganic

Ref No. 201811008726).
BIOMATERIALS:
The efforts are being
made to fabricate biocompatible HAp based scaffolds which can exhibit improved
corrosion resistant, mechanical strength. For this, the synthesis of a HAp-titania
based scaffolds with different morphologies and the studies on their corrosion,
cellular biocompatibility and adhesion behavior are undertaken. (Journal of
Materials Chemistry, 2010, 20,
4949–4954).
