| 2003-040 Discrete Polymer-Coated Nanoshells |
| |
A unique targeted drug delivery technology platform has been developed where a drug of interest is embedded in a biocompatible polymer that is attached to a nanoshell. The drug can be released on demand from the hydrogel by heating off the system thereby collapsing the hydrogel superstructure and getting the drug out to the desired spot in the body.

| 2004-010 & 2005-12 Carbon Nanotube Reinforced Polymer Nanocomposites |
| |
The present invention relates to a method of making highly dispersed nanotube based polymer nanocomposites. This new method allows the development of super-strong and ultra lightweight fibers and bulk nanocomposites of nylon, polyester and other high–performance based polymers. These new nanocomposites are biocompatible and biodegradable while possessing enhanced mechanical properties.

| 2004-026 Formation of Oxide Composites Direct by Carbon Combustion in Oxygen |
| |
Inventors: Dan Luss & Karen Martyrossian
The invention is a novel more economic synthesis of oxide ceramic composites such as: ferroelectrics, hard and soft magnetic ferrites, fuel cell components, superconductors, optoelectronics, battery electrode materials, catalysts, membranes, glass-ceramic, pigments and others. The method is a modification of self propagating high temperature synthesis (SHS) in which the heat needed for the synthesis is generated by combustion of carbon in oxygen rather than that of a pure metal. This enables a more economic production of the ceramic material and minimizes the presence of intermediate metal oxides in the product. The reactants mixture contains at least one metal or non metal oxide, or super oxide, or nitride, or carbonate, or chloride, or oxalate as a reactant and no pure metal. Pure carbon in the form of graphite or soot is added to the reactants mixture to generate the desired heat. The mixture is placed in a reactor exposed to gaseous oxygen. The high-temperature exothermic reaction between the carbon and oxygen generates a self-sustaining reaction in the form of a propagating temperature wave that causes a reaction among the reactants. The reaction proceeds rapidly following ignition. The final product contains simple or complex oxides of the elements. The new process also enables synthesis of oxides which cannot be produced by conventional SHS, when it is not possible to maintain a pure reactant metal in oxygen environment. An example is the synthesis of LiGaO2 or LaGaO3 by the new process.

| 2005-011 Novel Single-Step Preparation of Glycoamides for Surfactants and Detergents |
| |
A straightforward single-step process for the preparation or production of a novel family of carbohydrates has been developed. These new carbohydrates can find use as neutral detergents and surfactants. Carbohydrate moieties are linked to a carbohydrate chain via an amide bond. Carbohydrate moieties can be any monosaccharide and may include glucose, mannose, galactose, xylose, arabinose, ribose etc. The hydrophobic chain can be linear, branched, cyclic or aromatic.

| 2124 & 2320 Leucyl t-RNA Synthetases and Derivatives that Activate and Aminoacylate Non-Leucine Amino Acids to t-RNA Adaptor Molecules |
| |
The present invention relates to an in vitro enzymatic approach for the design of proteins containing unnatural amino acids where the inactivation of the editing active site using mutants of leucyl-tRNA synthetase allows amino acids other than the cognate leucine to be aminoacylated to tRNA. The resulting misaminoacylated tRNAs can be incorporated into in vitro or in vivo translation systems to incorporate non-standard or novel amino acids at specific sites within custom design proteins.

| 9622 Birefringence Grating Polarizing Beam Splitter |
| |
A birefringence polarizing beam-splitter is provided. A series or periodic blazed grooves or grooves with echelon profile having a number of steps is provided on the surface of an optically birefringent material. The birefringent substrate material may be crystalline or plastic. In another embodiment, two substrates of birefringment material having a series of periodic blazed grooves or grooves with echelon profile are combined to achieve greater angle of beam splitting.

| 9834 Bimodal Silicon Nitride/Barium Aluminum Silicate Ceramic Composites |
| |
A composition and method of fabricating pressureless sintered 70 volume % silicon nitride - 30 volume % barium aluminum silicate ceramic composites. The composites are made from 70 volume % silicon nitride, containing varying amounts and size distributions of initial β-silicon nitride, and 30 volume % barium aluminum silicate. The resulting ceramic composites contain microstructures with coarse β-silicon nitride whiskers, as well as narrow distributions of short β-silicon nitride whiskers, surrounded by fine barium aluminum silicate grains. The resulting composites exhibit improved fracture toughness and flexural strength.
