Facile coating of manganese oxide on tin oxide nanowires with high-performance capacitive behavior
In this paper, a very simple solution-based method is employed to coat amorphous MnO2 onto crystalline SnO2 nanowires grown on stainless steel substrate, which utilizes the better electronic conductivity of SnO2 nanowires ...
Wide-bandgap Zn2GeO4 nanowire networks as efficient ultraviolet photodetectors with fast response and recovery time
Ultraviolet (UV) photodetectors based on ternary Zn2GeO4 nanowire (NW) networks are demonstrated. The devices show fast response and recovery time, which is attributed to the unique NW-NW ...
Postchemistry of organic microrods : thermopolymerization in aqueous solution
Using the reprecipitation method, microrods of 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT) were prepared in aqueous solution. The as-synthesized microrods were found to polymerize in aqueous solution after heated at ...
Kinking-induced structural evolution of metal oxide nanowires into single-crystalline nanorings
We report an innovative method to fabricate single-crystalline nanorings based on the conventional vapor−liquid−solid (VLS) mechanism. The controllable formation of kinks in functional oxide nanowires (NWs) can be employed ...
Enhanced ferroelectric switching characteristics of P(VDF-TrFE) for organic memory devices
In the following work, we report an approach to shorten the ferroelectric switching time of P(VDF-TrFE) film by blending with as-synthesized gold nanoparticles. Ferroelectric hysteresis measurements give remnant polarization ...
Network-enhanced photoresponse time of Ge nanowire photodetectors
We demonstrated that the photoresponse time of Ge nanowire (NW) photodetectors could be greatly improved by using percolated NW networks (instead of single NW) as the active detection channels. Although the reset time for ...
Supercritical carbon dioxide-treated electrospun poly(vinylidene fluoride) nanofibrous membranes : morphology, structures and properties as an ionic-liquid host
A reverse-barrier technique is used to enable the treatment of electrospun poly(vinylidene fluoride) nanofibrous membranes with supercritical carbon dioxide. The treatment induces the formation of nanopores and extended-chain ...
Binder-free Co(OH)2 nanoflake–ITO nanowire heterostructured electrodes for electrochemical energy storage with improved high-rate capabilities
We present the fabrication of binder-free Co(OH)2 nanoflake–ITO nanowire heterostructured electrodes via a combination of chemical vapor deposition and electrodeposition methods for electrochemical energy storage applications. ...
Room-temperature synthesis of MnO2·3H2O ultrathin nanostructures and their morphological transformation to well-dispersed nanorods
MnO2·3H2O ultrathin nanostructures with sizes of 2–3 nm were synthesized at room temperature and transformation to well-dispersed nanorods was achieved after hydrothermal treatments.
Poly(vinylidene fluoride)-graft-poly(2-hydroxyethyl methacrylate) : a novel material for high energy density capacitors
We report the graft copolymerization synthesis of novel high dielectric constant HEMA (2-hydroxyethylmethacrylate)-graft-poly(vinylidene fluoride) (PVDF) copolymers for potential applications in high energy density capacitors. ...
