Virtual knots (links) and spatial graphs are two natural extensions of knots. In this thesis, we discuss
about invariants of virtual knots (links) and spatial graphs. Using crossing change operation and
virtualization, ...
The present thesis mainly concentrates on the problems of determining the structure of the
unit groups and unitary subgroups of finite modular group algebras. We obtain the structure
of the unit group and the unitary ...
Chalcogenide based quaternary compound: Cu2ZnSnS4 (CZTS), a Kesterite material, has been identified as a potential absorber for thin film solar cells. Salient features of CZTS such as, high absorption coefficient (>104 ...
Development of synthetic receptors is an important and active research field of
chemistry. The construction of artificial chemosensors for
cations/anions/biomolecules is of considerable importance due to the diverse
a ...
