Graphical abstract
Highlights► Phenol adsorption on a series of eight closed carbon nanotubes was measured ► We observe the linear correlation between surface area of tubes calculated from phenol and nitrogen adsorption ► Phenol can be applied as a probe molecule for comparative analysis of tube surface areas ► Adsorption process is mainly determined by the value of tube external surface areas and the tubes behave almost independently

HighlightsFexCo1-x nanowire arrays were prepared by both the symmetric and asymmetric ac electrodeposition method in AAO templates. The crystalline structure of the nanowires shows a bcc structure with a <110> preferred orientation. The energy dispersive spectroscopy analysis reveals the alloy composition is frequency independent and changes by Co and Fe ions concentration of the electrolyte. The growth rate of nanowires was enhanced with increase in reduction/oxidation voltage difference while the highest coercivity was found for the samples fabricated with symmetric potentials. It was found that in lower frequencies region alloy composition is more sensitize to the Fe and Co ions concentration.

Highlights► We furnish superconducting Nb thin films with linearly-extended uniaxial pinning nanostructures. ► An array of Co stripes is deposited by focused electron beam-induced deposition. ► Nanostructures are designed to be commensurate with the vortex lattice at small magnetic fields. ► We investigate vortex lattice matching effects by magneto-transport measurements. ► Drops in R(B) are observed only when the vortex lattice parameter matches the nanostructure period. ► No matching effects corresponding to the Co stripe width have been observed. ► Drops in R(B) are more pronounced for the vortex motion perpendicular to the Co stripes

Research highlights► Oxygen DBD plasma running at atmosphere pressure is an efficient modification method for the MWCNTs. ► Oxygen-containing group was generated on the surface of modified MWCNTs, and it would improve the dispersion stability of the MWCNTs. ► The oxygen ratio on the MWCNTs surface depends on the plasma treatment parameter, such as discharge power and treatment time. ► The surface area and total volume increase after the DBD plasma treatment.

Highlights► We present a new AFM based approach to measure the local dielectric response. ► It is based on the measurement of the second harmonic of the photosensor signal. ► This approach allows reaching unprecedented broad frequency range (2 – 3 104Hz). ► The method was tested on different poly(vinyl acetate) (PVAc) films.

Highlights► In this paper, we have observed the self-organisation phenomenon (nano/ micro-patterning) of the surface of NiO thin films on different substrates (SiO2, Si and Al) using 100 MeV Ag ions at LN2 temperature and at large incidence angle with the beam axis. ► AFM images of ion-beam irradiated samples show the restructuring of initially flat and coherent NiO film into an almost periodic NiO lamellae structure. ► The quite regular lamellae with width, height and average distance of hundreds of nm are oriented perpendicular to the beam direction. ► Section analysis of the AFM images reveal that the width of the lamellae is less in case of NiO films deposited on SiO2 substrate in comparison to Al substrate. ► The cracking and the development of lamellae structure is observed at higher fluence in the case of Al substrate in comparision to other substrates.

Materials Science and Engineering: B, In Press, Uncorrected Proof, Available online 18 May 2011

Highlights► There are no reports on fabrication of Tb3+-doped β-Ga2O3 nanofibers by the electrospinning technique. ► For β-Ga2O3:Tb3+ nanofibers, we observed several peaks corresponding to intra-4f transitions in Tb3+ ions and did not observe the blue band emission from Ga2O3 matrix. ► The blue emission of β-Ga2O3 host has been quenched when a low concentration of Tb3+ (0.5 mol%) ions was introduced, indicating that the energy migrated from β-Ga2O3 host to Tb3+ ions.
