In recent years, flexible electronic devices pursued for potential applications. The design and the fabrication of a novel flexible nanoarchitecture by coating electrical conductive MWCNT fiber with ultrathin films of MnO2to achieve high specific capacitance, for micro-supercapacitors electrode applications, are demonstrated here. The MWCNT/MnO2composite fiber electrode was prepared by the electrochemical deposition which was carried out through using two different methods: cyclic voltammetry and potentiostatic methods. The cyclic voltammetry method can get “crumpled paper ball” morphology MnO2which has bigger specific capacitances than that achieved by potentiostatic method. The flexible micro-supercapacitor was fabricated by twisting two aligned MWCNT fibers and showed an area specific capacitance of 2.43 mF/cm2. The flexible micro-supercapacitors also enable promising applications in various fields.

AbstractCyclic voltammetry (CV) was used to study the reduction potentials of 2,5-di(ethynylphenyl)-4-nitroaniline and 2,5-di(ethynylphenyl)nitrobenzene. Although no absolute reduction potentials can be used in the correlation between solution (CV) and solid state (nanopore) embodiments, each CV plot showed two reductions. The first and second reduction might correspond to switching events of recently reported molecular electronic devices in a nanopore. Cyclic voltammetry results are also reported for other potential molecular scale electronic devices.

Chemically Selective

The first few atomic layers of a solid can form a barrier between its interior and an often hostile environment. Although adsorption at the vacuum-solid interface has been studied in great detail, little is known about adsorption at the liquid-solid interface. Adsorption at a liquid-solid interface is of intrinsic interest, and is of technological importance because it provides a way to coat a surface with monolayer or multilayer structures. A pinhole free monolayer (with a reasonable dielectric constant) could lead to the development of nanoscale capacitors with unique characteristics and lithographic resists that surpass the resolution of their conventional counterparts. Chemically selective adsorption is of particular interest because it can be used to passivate a surface from external modification or change the wear and the lubrication properties of a surface to reflect new and useful properties. Immunochemical adsorption could be used to fabricate novel molecular electronic devices or to construct small, “smart”, unobtrusive sensors with the potential to detect a wide variety of preselected species at the molecular level. These might include a particular carcinogen in the environment, a specific type of explosive, a chemical agent, a virus, or even a tumor in the human body.
