Multifunctionalized Nanoparticles as a Delivery System

Vanderbilt researchers have created a novel nanoparticle that can be loaded with 2-8 times more drug than current delivery systems with a tailored linear release rate. They have demonstrated the power of this nanoparticle by effectively delivering the drug brimonidine, currently used in the treatment of glaucoma, to the retina at the back of the ey...

Structurally Designed Fuel Cell Catalysts for PEM or DMFCs

A method of producing colloidal, shaped nanoparticles of a transition metal or alloys thereof, comprising reducing ions of at least one transition metal in an aqueous solution thereof in the presence of at least one compound, which, at its isoelectric point, is a zwitterion and/or at least one small, non-polymeric anion and the nanoparticles produc...

Enhanced Cooling of Oil Based Transformers and Other Heat Generating Equipment with NanoParticle Suspensions

Nanometer-sized, low-cost, readily available, particulate nanodiamond is used as an additive to the mineral oil used in electrical power transformers and other oil-cooled electrical equipment to enhance the thermal conductivity [TC] and dielectric properties of the oil without compromising the oil’s required electrical insulation, such that failure...

Novel Carbon Nanofiber/Polymer Resins

Vanderbilt researchers have developed a method for generating a novel polymeric material. These materials contain relatively inexpensive carbon nanofiber additives that enhance the mechanical strength of polymer composites by as much as 45%, while adding less than 1 wt% to the material. By adjusting the synthesis process, other polymeric materials ...
