Aims The X-ray micro-tomography (micro-CT) technique has been used to visualize the microstructure of pharmaceutical granules produced by high shear wet granulation and the dynamic evolution of porosity during granule dissolution. The combination of time-resolved micro-CT imaging with UV/VIS detection of the quantity dissolved made it possible to evaluate the effective diffusion coefficient of ...

Fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. Micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). It is well known that the structure and prope...

We present high-resolution multi-frequency single-pulse observations of the Vela pulsar, PSR B0833−45, aimed at studying micro-structure, phase-resolved intensity fluctuations and energy distributions at 1.41 and 2.30 GHz. We find micro-structure in about 80% of all pulses independent of observing frequency. The width of a micropulse seems to depend on its peak flux density, whilst quasi-period...

The main objective of this research is to develop a micro and nanogap structure using dry anisotropic etching –Reactive Ion EtchingRIE. Amorphous silicon material is used in the micro and nanogap structure and gold as electrode. The fabrication processes of the micro and nanostructure are based on conventional photolithography, wet etching for the Al pattern and wet etching for a-Si pattern usi...

Non-wetting super-hydrophobic or super-lyophobic surfaces are of great interest in a variety of applications. Natural water repelling surfaces show micro-/nanocombined hierarchical structure which shows extremely low wettability and self-cleaning characteristics. Inspired by such natural wonders, there have been tremendous efforts to create artificial non-wetting super-hydrophobic or super-lyop...

In this paper, an observation on the toe pad of a newt was carried out. It was found that the pad surface is covered with an array of polygonal cells separated by channels, similar to those of a tree frog's pad. With this micro-structure, a newt can move on wet and smooth surfaces without slipping. Inspired by the surface structure of newt toe pads, elastic micro-patterned surfaces were fabrica...
