Silylation of Single-Walled Carbon Nanotubes

A non-destructive method to prepare semiconducting, silylated, single-walled carbon nanotubes Background: Single walled carbon nanotubes (SWNTs) possess unique structural, electronic, mechanical, and optical properties. The combination of the helicity and diameter of SWNTs, defined by the roll-up vector, that is, tube chirality, determines whether...

Titania and Titanate Nanostructures (BNL 15-26)

A method of synthesizing titanate and titania nanostructures and assemblies of them with controlled properties Background: Traditionally, synthesis of nanomaterials has relied on a number of imperfect approaches, like "top-down" and "bottom-up" methods. These methods are limited in terms of available shapes and sizes for the construction...

Method for Removing Strongly Adsorbed Surfactants and Capping Agents from Metal to Facilitate their Catalytic Applications

A method of synthesizing activated nanostructure electrocatalysts without damaging their surfaces. Background: Certain metals (like Pt, Pd, and Ru) are known as excellent electrocatalysts (catalysts in an electrochemical reaction), but they're also costly and scarce. They're also susceptible to carbon monoxide, have poor stability under cyclic loading,...
