Quantum Monte Carlo Study of Buckled GaAs Monolayer

18-Dec-2017 | Rajesh O. Sharma, Lalit K. Saini, Bhagwati Prasad Bahuguna, Macromolecular Symposia, 2017

We have investigated the ground state properties of buckled GaAs monolayer using density functional theory (DFT) and quantum Monte Carlo (QMC) method. Standard first‐principles approaches such as DFT with approximate exchange‐correlation functionals do not describe the correlation effect ...

Copolymer Nanocomposite Thin‐Films Under Shear

18-Dec-2017 | Lenin S. Shagolsem, Torsten Kreer, Jens‐Uwe Sommer, Macromolecular Symposia, 2017

By means of molecular dynamics simulations, we study the behaviour of lamellae forming diblock copolymer and nanoparticle mixtures in thin‐film geometry under stationary shear. In particular, we investigate the system under transverse mode of shear considering both nonselective and selective ...

2D Structured Nano‐Sheets of Octadecylamine Grafted Graphitic‐Carbon Nitride (g‐C3N4) as Lubricant Additives

18-Dec-2017 | Ajay Kumar, Gananath D. Thakre, Pankaj K. Arya, Amar K. Jain, Macromolecular Symposia, 2017

The present paper introduces new type of 2D structured nano‐sheets as additives for lubricating oils. The 2D structured nano‐sheets of graphitic‐C3N4 (g‐C3N4) have been grafted with Octadecylamine to be used as additives. The nano‐fluids have been synthesized by blending amine grafted g‐C3N4 in ...

Design of 2D Ferromagnets With High Exchange Bias in Fe‐MoS2 Heterostructure For Spintronic Applications

18-Dec-2017 | Shatabda Bhattacharya, Shyamal K. Saha, Macromolecular Symposia, 2017

Fe‐MoS2 heterostructures are synthesized in simple hydrothermal method. Different concentrations of Fe precursor are used to grow different thickness of Fe thin sheets placing MoS2 as a template surface. Different characterization techniques are done to confirm the desired phases present in the ...
