We report enhanced figure of merit, ZT, in p-type Bi0.4Sb1.6Te3 nanocomposites fabricated by a rapid and high throughput method of mixing nanostructured Bi0.4Sb1.6Te3 particles obtained through melt spinning with micronsized ...
Electrically tunable dielectric materials and strategies to improve their performances
Electrically tunable dielectric materials have potential applications as various microwave devices, such as tunable oscillators, phase shifters and varactors High dielectric tunability, low dielectric loss tangent and ...
Synthesis of porous NiO nanocrystals with controllable surface area and their application as supercapacitor electrodes
We report a facile way to grow various porous NiO nanostructures including nanoslices, nanoplates, and nanocolumns, which show a structure-dependence in their specific charge capacitances. The formation of controllable ...
Controlled synthesis of copper-silicide nanostructures
Octahedral-shaped, spindle-shaped, and wire-shaped Cu3Si nanostructures were synthesized through a silicon void-filling process. Faceted silicon voids were observed to spontaneously grow at the SiO2/Si interface through ...
Properties of (K,Na)NbO3-based lead-free piezoelectric films prepared by pulsed laser deposition
To investigate the properties of (K,Na)NbO3-based lead-free piezoelectric films at the morphotropic phase boundary composition, we fabricated epitaxial [(K0.5Na0.5)0.97Li 0.03] (Nb0.8Ta0.2)O3 films on (001), (110) and ...
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 ...
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.
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 ...
Synthesis of high surface area mesostructured calcium phosphate particles
High surface area mesostructured calcium phosphate (MCP) particles were synthesized using surfactants 21 (F127 and P123) and the textural properties optimized in this study. The synthesized MCP samples 22 subsequently ...
Controlled synthesis of Sb nanostructures and their conversion to CoSb3 nanoparticle chains for li-ion battery electrodes
Nanostructured Sb was prepared through a simple polyol process. Either Sb nanoparticles (Sb NP) or nanowires (Sb NW) were obtained by adjusting the concentration of surfactant. Electrochemical analyses revealed that the ...
