Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

Owning to their unparalleled sensitivity resolution, nanomechanical resonators have excellent capabilities in design of nano-sensors for gas detection. The current challenge is to develop newdesigns of the resonators for differentiating distinct gas atoms with a recognizably high sensitivity. In this work, the characteristics of impulse wave propagation in carbon nanotube-based sensors are inve...

Multifunctional carbon nanotubes are promising for biomedical applications as their nano-size, together with their physical stability, gives access into the cell and various cellular compartments including the nucleus. However, the direct and label-free detection of carbon nanotube uptake into cells is a challenging task. The atomic force microscope (AFM) is capable of resolving details of cell...

In the present study, the effect of material and process parameters on the morphological and hardness properties of friction stir process (FSP) acrylonitrile butadiene styrene (ABS) were investigated. For this purpose, firstly ABS polymeric sheets were injection molded. Then a slot with predetermined depth and width was created on sheets using a horizontal milling machine. Nano type (nanoclay, ...

Scanning transmission X-ray microscopy was used to chemically image RuO(2) nano-layer coated multi-walled carbon nanotubes (RuO(2)/MWCNT) with a spatial resolution of 30 nm. X-Ray absorption near-edge structure spectroscopy of individual RuO(2)/MWCNTs has been compared with that of MWCNTs and RuO(2) which confirms that RuO(2) interacts with MWCNTs through charge redistribution.

Inspired by the layered hierarchical nano- and microstructures of natural nacre, flattened double-walled carbon nanotube (FDWCNT) reinforced epoxy composites are fabricated. Impressively, the prepared composites exhibit layered structures analogous to nacre, and the FDWCNT loading can reach 70 wt%, which results in superior mechanical properties that evidently outperform other existing materials.

Nano-hybrid materials of single-walled carbon nanotubes (SWNTs) and polyoxometalates (POMs) with three counter cations were prepared and used as cathode-active materials of molecular cluster batteries (MCBs). The charging/discharging performances and thus battery capacity of the MCBs with hybrid materials were significantly better than those of the microcrystal-POM MCBs.

Carbon nanotubes and graphene are extra-ordinal material with remarkable electrical, optical, mechanical and thermal properties. Films of vertically aligned (VA-) SWNTs and horizontally aligned (HA-) SWNTs are synthesized on quartz and crystal quartz substrates, respectively. These aligned film should inherit the remarkable properties of SWNTs. The recent progress in growth control and characte...
