Carbon Nanotube Tower-Based Supercapacitor

Ames Research Center, Moffett Field, California A new technology to create electrochemical double-layer supercapacitors is provided using carbon nanotubes as electrodes of the storage medium. This invention allows efficient transport between the capacitor electrodes through the porous nature of the nanotubes, and has a low interface resistance between the electrode material and the collector. Carbon nanotubes directly grown on a metal surface are used to improve the supercapacitor performance. The nanotubes offer a high surface area and usable porosity for a given volume and mass, both of which are highly desirable for supercapacitor operation.

Magnetic Responsive Hydrogel Material Delivery System

Magnetic nanoparticles can be used as contrasting agents in MRIs, and as a drug delivery mechanism. Interest in the design of new drug delivery systems focuses on releasing the drug at a controlled rate and desired time. Magnetic nanoparticles (MNPs) have shown great potential for use in biomedicine due to their ability to get close to biological entities such as cells, viruses, proteins, and genes with heating ability when exposed to a time-varying magnetic field. Superparamagnetic MNPs with proven biocompatibility have attracted attention as drug carriers in hyperthermia therapy, magnetic resonance imaging (MRI) as a contrasting agent, tissue repair, immunoassay, and cell separation procedures.

Die Extrusion Technology for Medical Tubing Applications

Patent-pending process would allow 1000-plus layers from a single extruder.Although the concept of nanotechnology (controlling matter on an atomic scale) dates back to 1959, it is only now becoming more commercially realized. It has the potential to challenge the way all products are extruded in almost every type of medical tubular or related industrial product applications.
