Biomimetics (or biomimicry) is a field of technologies based on imitating various functions and properties of organisms. examined structure structures the scale nanoholes, the thin water is costly and unsuitable for mass production. To overcome these issues, we sought to develop elemental technologies for providing antifouling properties to biliary stents, which are made of polyethylenes (PEs), by forming nanostructures directly on the inner surface, using atmospheric pressure low-temperature plasma. We formed nanostructures on the inner walls of PE tubes of varying diameters under varying plasma conditions. We then examined the resulting structures and effects of the antifouling properties thus imparted.

A multiblock amphiphile CBA bearing a cationic imidazolinium moiety at its center formed different types of assembly in THF and CHCl 3 , which show characteristic emission bands around 300 and 465 nm upon excitation at 295 and 320 nm, respectively. These assemblies were able to be transferred into lipid bilayer membranes, keeping the similar spectral profiles with those in solutions. These results indicate a new potential of self-assembling processes for the control of supramolecular architecture hierarchically formed in lipid bilayer membranes.

time was long enough, the particles in the skin layer were much larger than the original particle size less than 100 nm [10]. A mixture composed of good solvent and poor solvent is used as the solvent used for production of an asymmetric membrane. The composition of the mixed solvent is very important for both the formation of the skin layer by vitrification and the formation of the support layer by liquid-liquid phase separation [20]. DCM is a good solvent and TCE and BuOH are poor solvents for the FPI used. Fig. 9 shows the temporal change of light transmittance after casting of the polymer solution containing the particles. The transmittance decreased immediately after casting and became constant after 70 seconds. The change in transmittance originated in the phase separation in the polymer solution cause by the evaporation of the DCM. This liquid-liquid phase separation would also result in the aggregation of the surface-modified silica nanoparticles in polymer solution. The mixed solvent used this time was suitable for formation of an asymmetric membrane for the neat FPI. However, in order to fabricate an asymmetric MMM, a solvent composition that allows suppression of particle aggregation in polymer solution during solvent evaporation will be required.

In this paper, a flexible and semi-transparent antenna is proposed having impedance bandwidth of 110 MHz (from 2.45 GHz to 2.56 GHz) of ISM band which covers the most popular (2.4 GHz) for Wi-Fi application all over the world. A simple dipole shape rectangular ring antenna with two extended edge on the opposite sides was prepared by laser direct writing on an Au sputtered PET film. The center part of the antenna was kept empty and transparent intentionally to incorporate with either a planar capacitor for microwave wireless charging or to integrate this antenna with a solar cell in future. The compact, miniature and flexibility of the antenna are suitable for easy integration in any smart devices or clothing for wireless charging to implement self-powered sensors. The performance of the patch antenna is evaluated using return loss (S11) parameter analysis. A measured reflection coefficient and simulated current distribution along with radiation pattern demonstrate that the fabricated antenna is suitable for Wi-Fi application.
