1. A brief review on the structural analysis of Graphene Oxide
Author:  Reshmi Bose
Abstract: Graphene is considered as one of the important allotropes of carbon as two dimension honeycomb lattice. Graphene can be oxidised into graphene oxide (GO) by several process and due to presence of oxygen containing functional groups on the basal plane graphene oxide is non conductive in nature but it can readily dissolved in most of the solvents like water. Thus GO can be used in different fields of material science like in batteries, capacitor and solar cells. This review article covers a brief review on the structural analysis of graphene oxide like the presence of oxygen containing functional groups and their positions, various spectral analysis of graphene oxide and other such studies.
2. A study of an Exotic Quantum Damped
Author:  Manjari Duttaa, Shreemoyee Ganguly, Sunandan Gangopadhyay
Abstract: We have studied a two-dimensional damped harmonic oscillator in time dependent noncommutative
space in an earlier communication [Int. J. Theor. Phys. 59, 3852 (2020)]. In this paper we have
reconsidered the same model and extended the discussion by introducing a generalised solution of
Ermakov-Pinney (EP) equation. We proceed to estimate the expectation value of energy in this
state.
3. Superior Mechanical Properties of SWCNT Incorporated Borosilicate Glass Composite
Author:  Sujan Ghosh
Abstract: The conventional melt-quench technique was employed for the fabrication of single walled carbon
nanotube (SWCNT) – borosilicate glass composite. Reduced Young’s modulus (Er) and Brittleness
index (B) were evaluated using indentation method both for the borosilicate glass and the SWCNT
incorporated borosilicate glass composite. Er value of the composite was higher compared to the
base glass. On the other hand the composite shows lower brittleness index than that of the base glass
where the reduction was more prominent in the higher load. However, those interesting properties of
the composite were explained by the existence of mechanically robust SWCNTs and their different
characteristics.
4. Direct Visualization of Plasmon Assisted photon emission from an Isolated Au nanorod with sharp tips
nanorod with sharp tips
Author:  Arpan Maiti
Abstract: Plasmonics is an emerging area of research that opens the path for controlling light-matter interac- tions at nanometer scale. The field of plasmonics have great practical uses in sensing, photovoltaics,
photocatalysis, environmental monitoring and national security. In this report we study the plas- mon assisted photon emission from an isolated single Au nanorod (length 640 nm and width 200 nm) with sharp tips using cathodoluminescence (CL) spectroscopy and imaging technique which is attached with a high resolution scanning electron microscope (SEM). Here CL spectroscopy and imaging technique is used to probe and directly map the localized surface plasmon modes supported by the sharp tipped Au nanorod. The unique high resolution spectroscopy and imaging technique enables us to directly visualize light-matter interactions on the sub-wavelength scale.
