Preparation and stability of template-synthesized metal nanorod sols in organic solvents

Article Abstract:

A study was conducted to examine the preparation and stability of metal nanorod sols in organic solvents by the template synthesis method. The stability of the nanorod sols were examined using visible absorption spectroscopy. Results indicated that the addition of polymeric stabilizers did not improve the stability of the sols. Findings also showed that reasonably stable gold and silver nanorod sol;s can be determined from 40-nm diameter nanorods.

Solvent-extraction and Langmuir-adsorption-based transport in chemically functionalized nanopore membranes

Article Abstract:

The transport property of nanopore alumina membranes that are rendered hydrophobic by functionalization with octadecyltrimethoxysilane (ODS), where transport mechanism involves Langmuir-type adsorption, is investigated. The supported-liquid membranes display substantially better transport selectivity than the ODS-modified membranes that contain no liquid subphase due to this different transport mechanism.

Effect of crown ether on ion currents through synthetic membranes containing a single conically shaped nanopore

Article Abstract:

A study is conducted to show that adding crown ether commonly called 18-crown-6 (18C6) to the electrolyte solution on one side of a conical nanopore membrane provides a way to rectify the ion current flowing through the nanopore. The results have potential ramifications in controlling ion transport in nanofluidic channels and in the development of nanofluidic circuits.
