Multifunctional, catalytic nanowire membranes and the membrane-based 3D devices

Article Abstract:

A new hydrothermal synthesis of Ti[O.sub.2]-based long nanowire catalysts that are cast directly into thermal-stable, robust and multifunctional free-standing membrane (FSM)-based 2 dimensional (2D) paper and 3D devices in nearly any macroscopic size and shape is reported. These nanowires have displayed unusual potentials in applications such as catalytically splitting water and cracking oil, making protection mask and armor, fabricating flame-retardant fabric, filtering bacteria, photoassisted rewriting, sensing and regenerating tissues.

Surface enhanced Raman scattering effects of silver colloids with different shapes

Article Abstract:

Three kinds of silver colloids, self-assembled nanowires, triangular nanoplates and quasispherical nanoparticles are synthesized by solution-based method. TEM studies revealed that they exposed different crystal planes such as {111} crystal planes to triangular nanoparticles, mainly {100} and {111} planes to self-assembly nanowires.

Polarized surface enhanced Raman scattering from aligned silver nanowire rafts

Article Abstract:

Oriented arrays of silver nanowires are fabricated and then used to illustrate the special and strongly polarization-dependent enhancement possible in interwire region.
