We report a wicking material based on nanostructured TiO2 (NST) for the application of flat heat pipes. Heat pipes adopt wicking materials to achieve some unique functions that thermal siphons could not achieve[1], and they have found their applications as cooling systems in a wide variety of areas such as spacecraft and electronics. Different kinds of materials such as carbon nanotubes[2], nan...

As a p-type semiconducting oxide that can absorb visible light, cuprous oxide (Cu2O) is an attractive material for solar energy conversion. This work introduces a high-temperature, vapor-phase synthesis that produces faceted Cu2O nanowires that grow epitaxially along the surface of a lattice-matched, single-crystal MgO substrate. Individual wires were then fabricated into single-wire, all-oxide...

Photoconductivities of monocrystalline vanadium pentoxide (V2O5) nanowires (NWs) with layered orthorhombic structure grown by physical vapor deposition (PVD) have been investigated from the points of view of device and material. Optimal responsivity and gain for single-NW photodetector are at 7,900 A W-1 and 30,000, respectively. Intrinsic photoconduction (PC) efficiency (i.e., normalized gain)...

Standard sacrificial template synthesis allows metal oxide nanotubes to be produced from ZnO nanowires. In spite of their high interest in several technological fields, the low surface area of these nanotubes is a drawback for most applications. Here we report for the first time the sacrificial template synthesis of stainless steel wire-mesh (SSWM) supported metal oxides of high technological i...

CoFe/Cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. Nanowires with 30 nm diameter and the definite lengths were obtained. The effect of CoFe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. The layers thickness was controlled t...

A facile top-down/bottom-up hybrid nanofabrication process based on programmable temperature control and parallel chemical supply within microfluidic platform has been developed for the all liquid-phase synthesis of heterogeneous nanomaterial arrays. The synthesized materials and locations can be controlled by local heating with integrated microheaters and guided liquid chemical flow within mic...

The photocatalytic activity of silver-based catalysts containing different amounts molybdenum disulfide (MoS2; 5, 10 and 20 wt.%) was evaluated by the degradation antibiotic ciprofloxacin production hydrogen via water splitting. All silver (Ag)-based degraded more than 70% in 60 min. catalyst that exhibited best result 5%Ag@TiO2-P25-5%MoS2, with ca. 91% degradation. control experiments stabilit...
