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.
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.
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.
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.
