Capacitive deionization (CDI) is an effective method for desalination of brackish water to alleviate the global freshwater crisis. Obtaining high capacity primary focus this field. Based on capacitive and pseudocapacitive behavior electrodes, current research mainly devoted increasing specific surface area electrode materials, however, NaCl adsorption typically limited range 10–20 mg g−1. In wo...

We have fabricated sub-micron intrinsic Josephson junctions in thin films of Tl-Ba-Ca-Cu-O using two differing techniques suited to different applications. By using lateral focussed ion-beam milling we have created arrays of intrinsic junctions in -axis oriented films. Such arrays, with areas as low as 0.25 m, display large hysteresis comparable to that observed in single-crystal intrinsic junc...

An approach is demonstrated for growing aligned ZnO nanowire/nanorod arrays following a predesigned pattern and feature with controlled site, shape, distribution, and orientation. The technique relies on an integration of atomic force microscopy (AFM) nanomachining with catalytically activated vapor-liquid-solid (VLS) growth. The pattern and growth locations are defined by the catalyst distribu...

Spatial dispersion effect of aligned carbon nanotubes (CNTs) in the terahertz (THz) region has significance for both theoretical and applied consideration due to the unique intrinsically anisotropic physical properties of CNTs. Herein, we report the angular dependent reflection of p-polarized THz wave from vertically aligned multi-walled CNT arrays in both experiment and theory. The spectra ind...

Vertically aligned carbon nanotube (CNT) arrays are grown on a moving substrate, demonstrating continuous growth of nanoscale materials with long-range order. A cold-wall chamber with an oscillating moving platform is used to locally heat a silicon growth substrate coated with an Fe/Al2O3 catalyst film for CNT growth via chemical vapor deposition. The reactant gases are introduced over the subs...

Vertically-aligned carbon nanotubes possess many advantages for a wide range of multifunctional applications. Along with the controlled growth of aligned/micropatterned carbon nanotubes, surface modification of vertically-aligned carbon nanotubes are essential in order to meet specific requirements demanded for particular applications. While many innovative synthetic methods have been developed...
