A topical composition includes a nanoemulsion of a plurality of hydrophobic particles having a hydrophilic coating therein. The hydrophobic particles are derived from the same or different hydrophobic material and each hydrophobic particle has a melting point below the melting point of the respective hydrophobic material. The hydrophobic particles comprise a mean particle size of less than about 10 nm, and the nanoemulsion further includes one or more pharmaceutically active agents.

A method of preparing a high capacity nanocomposite cathode of FeFin carbon pores may include preparing a nanoporous carbon precursor, employing electrochemistry or solution chemistry deposition to deposit Fe particles in the carbon pores, reacting nano Fe with liquid hydrofluoric acid to form nano FeFin carbon, and milling to achieve a desired particle size.

A method includes producing an article having a substrate with a plurality of independent taggant layers that each include metal oxide nanocrystals doped with at least one Lanthanide element. Each taggant layer includes metal oxide nanocrystals doped with a different Lanthanide element than each other taggant layer.

A polymerizable ligand comprising, in one embodiment, a polyaromatic compound, with a terminal functional group, non-covalently bonded to the sidewalls of carbon nanotubes. This structure preserves the structural, mechanical, electrical, and electromechanical properties of the CNTs and ensures that an unhindered functional group is available to bond with an extended polymer matrix thereby resulting in an improved polymer-nanotube composite.

A method and apparatus for evaluating a bioaerosol sample is provided which includes detecting frequency and/or time resolution factors that allow discriminate between a plurality of signals emitted by the bioaerosol to selectively detect biological materials contained in the bioaerosol sample from materials of non-biological origin and potentially associated with a pathogenic bioaerosol.

Thermal interfaces and methods include an array of carbon nanotubes aligned substantively perpendicularly from a substrate. One method includes arranging metal catalyst particles with a particular ligand on a fluid surface of a Langmuir-Blodgett trough. This forms uniformly spaced particles with spacing based on the particular ligand. The uniformly spaced metal catalyst particles are deposited on a substrate and carbon nanotubes are grown on the particles using chemical vapor deposition. A thermal interface can be produced with a carbon nanotube packing ratio greater than fifty percent and used in a thermal switch or other device. In some methods, commercially available nanotubes are condensed on a substrate using carbon nanotubes with terminal carboxylic acids in solution and an amine monolayer on the substrate. Pretreatment of the nanotubes in a switch by applying heavy pressure between two surfaces results in good thermal conductivity between those surfaces at smaller operating pressures.
