In this research we have studied aimed to compare the adsorption of dexamethasone by two adsorbent; multi-wall carbon nanotube and activated carbon with the help of UV/VIS spectrophotometer Jenway 6505 model. Adsorption chart based on the wavelength of dexamethasone has been obtained and the relevant graph is plotted by considering factor of concentration. Four different concentrations necessar...

Single-walled carbon nanotube encapsulated in boron nitrite (SWCNT@BNNT) is a novel nanomaterial with one-dimensional van der Waals (1D-vdW) heterostructure. In this paper, we demonstrated that the SWCNT@BNNT has an enhanced optical power tolerance compared to of pristine SWCNT while exhibiting saturable absorption properties. Under intensity 13kW/cm2, lifetime found be 2,270 times longer than ...

Fuse Filament Fabrication of conductive nanocomposites at selected low resistivity. 3D manufactured with applications for thermoelectric devices/sensors. Anisotropy in electro-mechanical behaviour multilayer nanocomposites. Conductivity CNT composites depends on filler content, process geometry. The following paper ...

In this paper, the radial breathing mode (RBM) frequency of single-walled carbon nanotube (SWCNT) is studied based on the thin shell theory. For this purpose, SWCNT is considered as an elastic thin cylindrical shell. The dynamic equation of RBM is derived using the Hamilton’s principle. An analytical solution of the RBM frequency of SWCNT is obtained. The advantage of this formulation is that i...

Nickel-iron layered double hydroxide (NiFe LDH) platelets with high morphological regularity and sub-micrometre lateral dimensions were synthesized using a homogeneous precipitation technique for highly efficient catalysis of the oxygen evolution reaction (OER). Considering edge sites are point activity, efforts made to control platelet size within dispersions. The goal is controllably isolate ...

In this research article, we analyze phonon scattering in branched single-walled carbon nanotube (SWCNT) networks with SWCNT–SWCNT Tand Xjunctions using the wave packet method. Five phonon branches including the longitudinal acoustic, twisting, transverse acoustic, radial breathing, and flexural optical modes are selected to study energy reflection, ramification, and transmission through Tand X...

In the present work, effect of von Karman geometric nonlinearity on the vibration characteristics of a Y-shaped single walled carbon nanotube (Y-SWCNT) conveying viscose fluid is investigated based on Euler Bernoulli beam (EBB) model. The Y-SWCNT is also subjected to a longitudinal magnetic field which produces Lorentz force in transverse direction. In order to consider the small scale effects,...

The synthesis of precisely defined nanoscale hybrid materials remains a challenge at the frontier of chemistry and material science. In particular, the assembly of diverse high-aspect ratio one-dimensional materials such as gold nanorods and carbon nanotubes into functional systems is of ever increasing interest due to their electronic and sensing applications. To meet these challenges, methods...

In this study, we have investigated radius dependence of hydrogen storage within armchair (n,n) single walled carbon nanotubes (SWCNT) in a square arrays. To this aim, we have employed equilibrium molecular dynamics (MD) simulation. Our simulations results reveal that radius of carbon nanotubes are an important and influent factor in hydrogen distribution inside carbon nanotubes and consequentl...

The presence of defects in a regular structure of graphene and carbon nanotubes (CNTs) can significantly influence their mechanical properties. In this work, the effect of an absence of a carbon atom (vacancy defect) on the strength of a graphene sheet and a single walled carbon nanotube (SWCNT) is studied using quasi static molecular dynamics (QSMD) simulations. Results show that a graphene sh...
