We report a novel class of amphiphilic conjugated block copolymers composed poly(3-octylthiophene) and poly(ethylene oxide) (POT-b-PEO) that exhibit highly tunable photoluminescence colors spanning from blue to red. POT-b-PEO self-assembles into various well-defined core/shell-type nanostructures as result its amphiphilicity. The self-assembly structure can be readily controlled by altering the solvent composition or other external stimuli. color change was completely reversible,...
Harvesting the ambient mechanical energy that is abundant in living environment a green technology which can allow us to obtain an eco-friendly and sustainable form of energy. Here, we report powder-based triboelectric nanogenerator (P-TENG) using polytetrafluoroethylene powder as freestanding layer. By employing powder, has fluid-like characteristics, device able harvest random vibrational from all directions be fabricated regardless size or shape its container. Notably, this shows...
Abstract We report the transient memory device by means of a water soluble SSG (solid sodium with glycerine) paper. This material has hydroscopic property hence it can be in water. In terms physical security devices, prompt abrogation which stored large number data is crucial when stolen because all things have identified information device. By utilizing paper as substrate, we fabricated disposable resistive random access (RRAM) good retention longer than 10 6 seconds and cycling endurance...
Abstract The importance of poly-crystalline silicon (poly-Si) in semiconductor manufacturing is rapidly increasing due to its highly controllable conductivity and excellent, uniform deposition quality. With the continuing miniaturization electronic components, low dimensional structures such as 1-dimensional nanowires (NWs) have attracted a great deal attention. But components much higher current density than 2- or 3- films high can degrade device lifetime lead breakdown problems. Here, we...
The energy harvesting interface circuit is proposed for wind-driven triboelectric nanogenerator (WD-TENG). To extract power from the WD-TENG maximally and deliver to output (battery) efficiently, a rectifier-reusing bias-flip (RRBF) technique multiphase reconfigurable switched-capacitor converter (MRSCC) are developed. In RRBF, low-side switches of rectifier reused as without additional components. MRSCC delivers battery efficiently by reducing switching loss including overlap loss....
