| 20110108815 | MULTI-RATE RESIST METHOD TO FORM ORGANIC TFT CONTACT AND CONTACTS FORMED BY SAME - A method for forming a thin film electrode for an organic thin film transistor of the invention provides a multi-layer mask on a substrate with an electrode area opening in a top layer of the mask that is undercut by openings in other layers of the mask. A thin film of metal is deposited in the electrode area on the substrate. Removing the multi-layer mask leaves a well-formed thin film electrode with naturally tapered edges. A preferred embodiment of the invention is a method for forming a thin film electrode for an organic thin film transistor. The method includes depositing a first layer of photoresist on a substrate. The photoresist of the first layer has a first etching rate. A second layer of photoresist is deposited on the first layer of photoresist. The photoresist of the second layer has a second etching rate that is lower than the first etching rate. The first and second layer of photoresist are patterned by exposure. Developing the first and second layers of photoresist provides an electrode area on the substrate. An electrode is deposited in the electrode area. Lift-off of the first and second layers is performed. The electrode that is deposited has a tailored, tapered edge. A preferred embodiment thin film electrode in an organic thin film transistor has a tapered edge with a contact angle of approximately +40±4.4°. | 05-12-2011 |
| 20110073531 | DYNAMIC EQUILIBRIUM SEPARATION, CONCENTRATION, AND MIXING APPARATUS AND METHODS - Particles are separated, concentrated, or mixed within a fluid by means of a fluid-containing cell having a longitudinal axis, a cross-sectional area generally perpendicular to the longitudinal axis, and at least one particle motivating force directionally interacting with at least one recurrent circulating fluid flow generally aligned with the longitudinal axis within the fluid containing cell. | 03-31-2011 |
| 20110042353 | NANOMETER-SCALE ABLATION USING FOCUSED, COHERENT EXTREME ULTRAVIOLET/SOFT X-RAY LIGHT - Ablation of holes having diameters as small as 82 nm and having clean walls was obtained in a poly(methyl methacrylate) on a silicon substrate by focusing pulses from a Ne-like Ar, 46.9 nm wavelength, capillary-discharge laser using a freestanding Fresnel zone plate diffracting into third order is described. Spectroscopic analysis of light from the ablation has also been performed. These results demonstrate the use of focused coherent EUV/SXR light for the direct nanoscale patterning of materials. | 02-24-2011 |
| 20100319746 | HIGH EFFICIENCY THERMOELECTRIC POWER GENERATION USING ZINTL-TYPE MATERIALS - The invention disclosed herein relates to thermoelectrically-active p-type Zintl phase materials as well as devices utilizing such compounds. Such thermoelectric materials and devices may be used to convert thermal energy into electrical energy, or use electrical energy to produce heat or refrigeration. Embodiments of the invention relate to p-type thermoelectric materials related to the compound Yb | 12-23-2010 |
| 20100092982 | Regulation of Gene Expression by Protein Methylation - The invention relates to the cDNA and deduced amino acid sequence of the Coactivator Associated arginine (R) Methyltransferase protein, CARM1. A method is described for the use CARM1 to regulate gene expression in vivo. CARM1 has also been used to methylate arginine residues of histones, synthetic peptides, and other proteins. A method to use CARM1 to screen for drugs that inhibit its methyltransferase activity is also described, as is a method to screen for drugs that modulate CARM1's interactions with other proteins. | 04-15-2010 |
