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 ...
Single crystalline semi-nanotubes of indium germanate
Single crystalline In2Ge2O7 nanotubes were synthesized by a thermal evaporation method. The growth mechanism of those novel seminanotubular structures was explained to be a vapor−liquid−solid (VLS) mechanism. Its morphology ...
Tuning photoluminescence of Ge/GeO2 core/shell nanoparticles by strain
The distribution of strain field plays an important role in deciding the physical properties of nanocrystals. The growth strain of Ge/GeO2 core/shell nanoparticles embedded in a regular array of Al2O3 nanoparticles and its ...
Plasmon-enhanced polarized Raman spectroscopy for sensitive surface characterization
Local-mode and localized surface plasmons generated on the silver thin film can selectively enhance the Raman signal from the surface. Further improvement of surface signal can be obtained by using the polarized Raman ...
Interfacial reacions of Ni on Si1-xGex (x=0.2, 0.3) at low temperature by rapid thermal annealing
The interfacial reaction of Ni with relaxed Si1-xGex (x=0.2,0.3) films in the low temperature range, viz., 300–500 °C, has been investigated and compared with ...
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. ...
Thermal stability of rare-earth based ultrathin Lu2O3 for high-k dielectrics
Lu2O3 thin film was deposited on n-type (100) Si substrates using pulsed laser deposition. A k value of 15.95 with an equivalent oxide thickness (EOT) of 1.10 nm and a current density of 2.6×10−5 A/cm2 at +1 V accumulation ...
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. ...
Electrochemical energy storage in a β-Na0.33V2O5 nanobelt network and its application for supercapacitors
We report a nanostructured oxide pseudocapacitor electrode utilizing a sodium-doped vanadium oxide (β-Na0.33V2O5) nanobelt network with a three dimensional framework crystal structure, which has been successfully synthesized ...
