“…However, classical continuum mechanics is a scale-free theory and cannot account for effects arising from small size. Experimental [5][6][7][8] and atomistic simulations 9,10 have evidenced a significant "size-effect" in mechanical and physical properties when the dimensions of the structures become "small." Size effects are related to atoms and molecules that constitute the materials.…”

The behaviour of carbon nanotubes in a magnetic field has attracted considerable attention in the scientific community. This paper reports the effects of a longitudinal magnetic field on the vibration of a magnetically sensitive double single-walled carbon nanotube system (DSWNTS). The two nanotubes of the DSWNTS are coupled by an elastic medium. The dynamical equations of the DSWNTS are derived using nonlocal elasticity theory. The two nanotubes are defined as an equivalent nonlocal double-Euler-Bernoulli beam system. Governing equations for nonlocal bending-vibration of the DSWNTS under a longitudinal magnetic field are derived considering the Lorentz magnetic force obtained from Maxwell's relation. An analytical method is proposed to obtain nonlocal natural frequencies of the DSWNTS. The influence of (i) nanoscale effects and (ii) strength of longitudinal magnetic field on the synchronous and asynchronous vibration phase of the DSWNTS is examined. Nonlocal effects with and without the effect of magnetic field are illustrated. Results reveal the difference (quantitatively) by which the longitudinal magnetic field affects the nonlocal frequency in the synchronous and asynchronous vibration modes of a DSWNTS.

“…Various studies have shown that the heat treatment in TiO 2 nanotubes produces a series of phase changes, eventually developing rutile as the stable phase after heat treatment above ~500 ºC 21 . Bauer et al, 22 evaluated the influence of anodization potential in the TiO 2 nanotubes growth. The authors observed that the increase of the diameter was directly proportional to the potential increase.…”

In this study, the effects of the parameters such as applied potential difference, time and annealing temperature in the titania nanotubes formation were evaluated. The morphology of the nanotubes was evaluted by using Field Emission Gun -Scanning Electron Microscope (FEG-SEM), Atomic Force Microscope (AFM), contact angle and X-rays diffraction (XRD). Self-organized nano-structures were formed on the Ti-7.5Mo alloy surface from the same electrolyte (glycerol/NH4F) for all conditions. It was observed that the potential influenced the diameter while the length was changed according to the anodization time lenght. The presence of the phases anatase and rutile was altered by annealing temperature. Results showed that 20V-48h-450 ºC was the better than other conditions for application as biomaterial.

“…Li et al [25] reported that the long process of anodizing could increase the length of the tube that increase the thickness of TiO 2 NT. Bauer et al [2] and Nischk et al [11] report that the growth of thickness of nanotube film could increase the intensity of the peak of anatase. It is also influenced by the amount of surface area of TiO 2 NT in the material.…”

“…In the last few years, TiO 2 gives a great attention due to its ability to be used as photocatalyst materials, non toxic, self cleaning, sollar cells, gas sensing and corrosionresistant material with over 5000 publications that have been produced [1][2]. TiO 2 in the micro powder form has a limitation to be used for the above application due to its low surface area, so that large amount of TiO 2 is required for those applications as has been postulated by Misriyani et al [3].…”
