Carbon nanomaterials are becoming increasingly significant in biomedical fields since they exhibit exceptional physicochemical and biocompatible properties. Today, the stem cells offer potentially new therapeutic approaches in tissue engineering and regenerative medicine. However, the induction of differentiation into specific lineages remains challenging, which provoked us to explore the biome...

In this paper, we have explored the feasibility of a carbon nanotube (CNT) ring oscillator (RO) for detecting ionized radiation. The effect of ion irradiation on the oscillation frequency of CNT-based RO is considered using the displacement damage dose (DDD) methodology. The analytical model of the irradiated resistance of metallic single-walled CNT (SWCNT) has been developed and verified by ex...

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,...

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...

Based on plasma-treated single wall carbon nanotubes (SWCNTs), SWCNT/SiO(2) and thiol groups-functionalized SWCNT/SiO(2) hybrids have been fabricated through a sol-gel process. By means of thiol groups, Ag nanoparticles have been in situ synthesized and bonded onto the SiO(2) shell of SWCNT/SiO(2) in the absence of external reducing agent, resulting in the stable carbon nanotube/SiO(2)/Ag nanop...

Two types of bacteria were placed on the top surface of carbon nanotube films and the composite film morphology was examined using scanning electron microscopy. The interaction of bacteria with the carbonaceous film was studied after drying and subsequent heating to 1000 °C. For gram-positive bacteria, subsequent shrinkage of the bacterial layer causes film stresses and roll-up, and for the gra...

This paper utilizes molecular-dynamics simulations to investigate the mechanical characteristics of a suspended (10, 10) single-walled carbon nanotube (SWCNT) during atomic force microscopy (AFM) nanoindentation at different temperatures. Spontaneous topological transition of the Stone-Wales (SW) defects is clearly observed in the indentation process. The present results indicate that under AFM...

The effects of Single Walled Carbon Nanotube (SWCNT) on mixed convection in a cavity are investigated numerically. The problem is studied for different Richardson numbers (0.1-10), volume fractions of nanotubes (0-1%), and aspect ratio of the cavity (0.5-2.5) when the Grashof number is equal to 103. The volume fraction of added nanotubes to Water as base fluid are lowers than 1% to make dilute ...

In this work, it has been investigated the Monkeypox disease which occurs in both humans and animals by infection with a double-stranded DNA virus having symptoms consisting of fever, fatigue, headache, muscle pains like flu. Tecovirimat drug can be applied prohibition monkeypox through adsorbing onto surface single-walled carbon nanotube (SWCNT) as delivery method due to direct electron transf...
