Ring type and π electron occupancy decides the Li-ion storage properties of Phagraphene: An example of sp2 hybridized carbon structure

Autor: Ranjit Thapa, A. Rajkamal, S. Sinthika, Gunther G. Andersson

Publikováno v: Carbon. 129:775-784

Graphite, a sp2 hybridized layered material is used as an anode material in commercial Lithium ion batteries (LIB's). It is desirable to improve the Li/C ratio in the sp2 hybridized carbon allotropes to increase the specific energy capacity. Using Fi

Publikováno v: Thin Solid Films. 642:316-323

In an attempt to introduce delocalized electronic states in the valance band of p-type delafossite crystals of CuFeO2, substitution with Mg in its lattice has been done in this work. The delafossite type crystal structure has been achieved at a compa

CO Oxidation Prefers the Eley–Rideal or Langmuir–Hinshelwood Pathway: Monolayer vs Thin Film of SiC

Autor: Ranjit Thapa, S. Sinthika, Surya Teja Vala, Yoshiyuki Kawazoe

Publikováno v: ACS Applied Materials & Interfaces. 8:5290-5299

Using the first-principles approach, we investigated the electronic and chemical properties of wurtzite silicon carbide (2H-SiC) monolayer and thin film structures and substantiated their catalytic activity toward CO oxidation. 2H-SiC monolayer, bein

Enhanced electrochemical performance by facilitating Li-ion diffusion in LiNi0.1MgxCo0.9−xO2 (0≤ x ≤ 0.2) — for high energy Li-ion batteries

Autor: R. Nimma Elizabeth, S Sinthika, M. Pushpa Selvi, S. Padmaja, S. Arockia Shyamala Paniyarasi, J Arlyn Sneha

Publikováno v: Nano-Structures & Nano-Objects. 24:100559

Layered nano-sized LiNi 0.1 Mg x Co 0.9−x O2 (0 ≤ x ≤ 0.2) cathode materials for Li-ion batteries with very low nickel content were prepared by a self-sustaining solution combustion method. The structural and morphological properties were exami

CO oxidation on Pt based binary and ternary alloy nanocatalysts: Reaction pathways and electronic descriptor

Autor: S. Sinthika, Ranjit Thapa, Anjana Tripathi, Gunther G. Andersson, Chavana Hareesh

Publikováno v: Applied Surface Science. 528:146964

The design of stable, highly active heterogeneous nanocatalyst with no CO poisoning is a challenge for the catalytic converter industry. This can be achieved by defining electronic descriptor and by understanding the bonding mechanism. We present res

Colossal magnetoresistance in amino-functionalized graphene quantum dots at room temperature: manifestation of weak anti-localization and doorway to spintronics

Autor: Rajarshi Roy, Nilesh Mazumder, Gundam Sandeep Kumar, Nirmalya Sankar Das, Kalyan Kumar Chattopadhyay, Dipayan Sen, S. Sinthika, Ranjit Thapa

Publikováno v: Nanoscale. 8:8245-8254

In this work, we have demonstrated the signatures of localized surface distortions and disorders in functionalized graphene quantum dots (fGQD) and consequences in magneto-transport under weak field regime (∼1 Tesla) at room temperature. Observed p
