We report the fabrication of stretchable transparent electrode films (STEF) using 15-nm-diameter Ag nanowires networks embedded into a cross-linked polydimethylsiloxane elastomer. 15-nm-diameter Ag NWs with a high aspect ratio (˃1000) were synthesized through pressure-induced polyol synthesis in the presence of AgCl particles with KBr. These Ag NW network-based STEF exhibited considerably low haze values (<1.5%) with a transparency of 90% despite the low sheet resistance of 20 Ω/sq. The STEF exhibited an outstanding mechanical elasticity of up to 20% and no visible change occurred in the sheet resistance after 100 cycles at a stretching-release test of 20%.

AbstractWe address the template-directed deposition of metals on microtubule supports for generating metal nanostructures with different morphologies. Microtubules are highly ordered protein assemblies of tubular structure with a high aspect ratio. In this approach, the biostructure serves as a functionalised scaffold where the metal is generated in situ and shaped into a nanostructure with its morphology complementary to that of the biotemplate. When the biotemplate is coupled to an appropriate chemical reaction, different Ag / protein structures are produced, ranging from microtubules densely covered by small Ag nanoparticles to continuous Ag nanowires.

Lifting Surfaces

ABSTRACT A hybrid craft is defined as a combination of different lifting surfaces. The lift force can be of aerodynamic or hydrodynamic character. This research deals with the conditions of using planing mono-hulls equipped with a couple of wings, called planing-wing hybrid craft. A parametric study is conducted by using Vortex Lattice Method to determine feasibility of using an aerodynamic wing mounted to planing craft. It has been determined that the wing area should be more than twice as much as the wetted surface of the craft, to get an effective wing for planing craft. Furthermore, the wing should be so designed as to obtain its high aspect ratio. Maximum lift force contribution resulting from different wing configurations considered in this study is less than 35 percent of the total hydrodynamic lift force at an arbitrary condition. On this basis it may be concluded that the wing may be effectively used only in special conditions, hence this is not recommended for general application.

Noble metal nanoparticles have been a source of immense interest due to their novel properties and the uniqueness in properties due to high aspect ratio and quantum size effect resulting from their reduced size. In this paper, silver nanowires with an uniform diameter of 50nm were simply and successfully synthesized by solvothermal method using ethylene glycol as reducer in the presence of anodic alumina oxide (AAO) template. The experiment process is repeatable and the condition is moderate. The results of the field emission scanning electron microscope (FE-SEM) and the transmission electron microscope (TEM) show that there are more Ag nanowires with high aspect ratio produced on the surface of AAO and they are formed by many short nanowires connecting with each other from beginning to end. X-ray diffraction (XRD) and High-resolution transmission electron microscope (HRTEM) reveal that the prepared product is made of pure silver with face centered cubic structure. The optical properties were characterized by UV–Vis spectroscopy. The results reveal that Ag nanowires have a strong absorption band at about 378nm and 715nm which can be attributed to the transverse surface plasmon response(SPR) and the longitudinal surface plasmon response of the long silver nanowires.
