Filamentous Carbon Particles for Cleaning Oil Spills
The invention provides methods and apparatus for the creation of carbon filaments used for cleaning oil spills.
Crude oil and other petroleum products can cause severe damage to the environment and wildlife when spilled into the water. Oil is not only transferred by supertanker, but also by underwater pipelines an kept in coastal storage facilities. All of these have the potential to accidentally release crude oil int the ocean and sea. Due to the extreme environmental...

Method and Apparatus for Three-Dimensional Carbon Fiber Production
UCF researchers have discovered a method for producing three-dimensional carbon fibers. These novel fibers have a surface area approximately two orders of magnitude greater than the surface area of primary fibers.They are composed of original carbon fibers (OCF) with secondary carbon filaments (SCFs) grown thereon. Additional tertiary carbon filaments (TCF) can also be grown from the surface of SCFs, forming a filamentous carbon network with high surface area. The presence of carbon...

Wide Electrochemical Window Solvents
Typical electrolyte solvents for use in liquid or polymer electrolyte solutions include alkyl ethers and alkene carbonates. These solvents are used to dissolve electrolyte solutes and/or rubberizing polymer additives to form electrolyte solutions which may be used in electrochemical devices. However, these materials have significant disadvantages. Ethers are volatile and have low dielectric constants, while carbonates are unstable around alkali metals and have high melting points. |

Creation of Light and/or Surface Plasmons with Heated Metallic Films
Thin Metal Film Plasmonic Device
Ultrasmooth thin metal films with a nanoscale bull’s eye pattern of circular concentric grooves produce a monochromatic beam of collimated light when heated. The plasmonic device can be made from different metals such as tungsten, gold and silver or other combinations of materials. The wavelength of the emitted light can be tuned by changing the metal and the spacing of the concentric grooves of the bull’s eye pattern. The monochromatic...

Supertough Polylactide Composites
Biodegradable Plastics from Strengthened Polylactic Acid
Polylactic acid is a renewable polymer used for creating biodegradable plastics. Unfortunately, polylactic acid has limited applications due to its brittleness when compared to petroleum-derived plastics.
A process developed at the University of Minnesota can strengthen polylactic acid using less added material (as little as 1 wt% of non-polyactic acid material as opposed to 2-3 wt% for commercial additives) by creating a...
