Application of a High Order Accurate Meshless Method to Solution of Heat Conduction in Complex Geometries
Naman Bartwal, Shantanu Shahane, Somnath Roy +1
In recent years, a variety of meshless methods have been developed to solve partial differential equations in complex domains. Meshless methods discretize the partial differential…
Electronic Structure of Graphene/TiO Interface: Design and Functional Perspectives
Shashi B. Mishra, Somnath C. Roy, B. R. K. Nanda
We propose the design of low strained and energetically favourable mono and bilayer graphene overlayer on anatase TiO (001) surface and examined the electronic structure of the…
Study of Band structure, Transport and magnetic properties of BiFeO3-TbMnO3 composite
Prince Kr. Gupta, Surajit Ghosh, Arkadeb Pal +4
Magnetoelectric multiferroic composite of two types of multiferroic (Type I and II) consisting BiFeO3 and TbMnO3 is studied for enhanced magnetic and transport properties. A narrow…
Room temperature large spontaneous exchange bias in hard-soft antiferromagnetic composite BiFeO3-TbMnO3
Prince Kr. Gupta, Surajit Ghosh, Shiv Kumar +12
We report the presence of giant spontaneous exchange bias (HSEB) in a hard and soft antiferromagnetic composite of BiFeO3-TbMnO3 (BFO-TMO in 7:3 and 8:2 ratio). The HSEB varies bet…
Quantum Mechanical Process of Carbonate Complex Formation and Large Scale Anisotropy in the Adsorption Energy of CO on Anatase TiO (001) Surface
Shashi B. Mishra, Aditya Choudhary, Somnath C. Roy +1
Adsorption of CO on a semiconductor surface is a prerequisite for its photocatalytic reduction. Owing to superior photocorrosion resistance, nontoxicity and suitable band edge…
