| 20120074062 | MICROFLUIDIC DEVICES, PARTICULARLY FILTRATION DEVICES COMPRISING POLYMERIC MEMBRANES, AND METHODS FOR THEIR MANUFACTURE AND USE - The present disclosure describes devices useful for microscale fluid purification, separation, and synthesis. Such devices generally comprise a fluid membrane that separates two or more fluids flowing through plural microchannels operatively associated with the membrane. Often, the membrane is a semipermeable membrane, such as might be used with a filtration device, such as a dialyzer. Devices of the present invention can be combined with other microscale devices to make systems. For example, the devices may be coupled with one or more microchemical microfactories, one or more micromixers, one or more microheaters, etc. Examples of devices made according to the present invention included an oxygenator, a dialyzer, microheat exchangers, etc. | 03-29-2012 |
| 20120063475 | NONLINEAR OPTICAL CRYSTALS AND THEIR MANUFACTURE AND USE - Described are nonlinear optical (NLO) crystals, including aluminum-borate NLO crystals, that have low concentrations of contaminants that adversely affect the NLO crystal's optical properties, such as compounds that contain transition-metal elements and/or lanthanides, other than yttrium, lanthanum, and lutetium. Some NLO crystals with low concentrations of these contaminants are capable of second harmonic generation at very short wavelengths. Also described are embodiments of a method for making these NLO crystals. Some embodiments involve growing a single NLO crystal, such as an aluminum-borate NLO crystal, from a mixture containing a solvent that is substantially free of harmful contaminants. The described NLO crystals can be used, for example, in laser devices. | 03-15-2012 |
| 20110300567 | METHOD FOR DETERMINING REDOX ACTIVITY AND SCREENING COMPOUNDS BASED ON REDOX ACTIVITY - A method for identifying the redox activity of a subject compound is disclosed. The method can be performed aerobically and can include forming a mixture comprising a free-radical precursor and a compound to be tested, and converting the free-radical precursor into a free-radical anion and a free-radical cation. After the free radical cation and the free radical anion have been formed, the relative redox activity of the subject compound may cause a difference in the rate of photo-bleaching of the mixture and/or the rate of superoxide generation. These differences can be quantified and used to identify the redox activity of the subject compound. This sensitive technique for measuring redox activity can be used to screen compounds for various biological applications. Drugs also can be developed based on the relationship between redox activity and biological activity for particular biological applications. | 12-08-2011 |
| 20110300230 | FLUID PURIFICATION SYSTEM - Disclosed are systems and methods of preparing dialysate for use in a home dialysis system that is compact and light-weight relative to existing systems and consumes relatively low amounts of energy. The method includes coupling a household water stream to a dialysis system; filtering the water stream; heating the water stream to at least about 138 degrees Celsius in a non-batch process to produce a heated water stream; maintaining the heated water stream at or above at least about 138 degrees Celsius for at least about two seconds; cooling the heated water stream to produce a cooled water stream; ultrafiltering the cooled water stream; and mixing dialysate components into the cooled water stream in a non-batch process. | 12-08-2011 |
| 20110253629 | Microfluidic devices, particularly filtration devices comprising polymeric membranes, and method for their manufacture and use - The present disclosure describes devices useful for microscale fluid purification, separation, and synthesis devices. Generally, such devices comprise a fluid membrane that separates two or more fluids flowing through plural microchannels operatively associated with the membrane. The fluids can both be liquids, gases, or a liquid and a gas, such as may be used for gas absorption into a liquid. Often, the membrane is a semipermeable membrane, such as might be used with a filtration device, such as a dialyzer. Devices of the present invention can be combined with other microscale devices to make systems. For example, the devices may be coupled with one or more microchemical microfactories, one or more micromixers, one or more microheaters; etc. Examples of devices made according to the present invention included an oxygenator, a dialzyer, microheat exchangers, etc. Particular materials had to be developed for use with certain embodiments of the device disclosed herein. For example, a new composite material was made comprising nanocrystalline cellulose filler and a polysulfone polymeric material. A dialyzer comprising the composite membrane also is disclosed. In order to make the nanocrystalline cellulose-polymer composite, a new method was devised for making an organic dispersion of nanocrystalline cellulose. The method comprised first forming an aqueous dispersion of nanocrystalline cellulose. A mixture was then formed comprising the aqueous dispersion and an organic liquid having a boiling point higher than water. The water was then selectively removed to form a second mixture comprising the nanocrystalline cellulose and the organic liquid. | 10-20-2011 |
| 20110045406 | SOLUTION PROCESSED THIN FILMS AND LAMINATES, DEVICES COMPRISING SUCH THIN FILMS AND LAMINATES, AND METHOD FOR THEIR USE AND MANUFACTURE - Devices having a thin film or laminate structure comprising hafnium and/or zirconium oxy hydroxy compounds, and methods for making such devices, are disclosed. The hafnium and zirconium compounds can be doped, typically with other metals, such as lanthanum. Examples of electronic devices or components that can be made include, without limitation, insulators, transistors and capacitors. A method for patterning a device using the materials as positive or negative resists or as functional device components also is described. For example, a master plate for imprint lithography can be made. An embodiment of a method for making a device having a corrosion barrier also is described. Embodiments of an optical device comprising an optical substrate and coating also are described. Embodiments of a physical ruler also are disclosed, such as for accurately measuring dimensions using an electron microscope. | 02-24-2011 |
| 20100261304 | Solution-based process for making inorganic materials - Disclosed embodiments provide a solution-based process for producing useful materials, such as semiconductor materials. One disclosed embodiment comprises providing at least a first reactant and a second reactant in solution and applying the solution to a substrate. The as-deposited material is thermally annealed to form desired compounds. Thermal annealing may be conducted under vacuum; under an inert atmosphere; or under a reducing environment. The method may involve using metal and chalcogen precursor compounds. One example of a metal precursor compound is a metal halide. Examples of suitable chalcogen precursor compounds include a chalcogen powder, a chalcogen halide, a chalcogen oxide, a chalcogen urea, a chalcogen or dichalcogen comprising organic ligands, or combinations thereof. Certain disclosed embodiments concern a method for making a solar cell from I-III-VI semiconductors. | 10-14-2010 |
| 20100015625 | CTIP2 EXPRESSION IN SQUAMOUS CELL CARCINOMA - The present disclosure provides methods of diagnosing and staging squamous cell carcinomas, for instance head and neck (HNSCC), by detecting chicken ovalbumin upstream promoter-transcription factor-interacting protein 2 (CTIP2) expression. For example, it is demonstrated herein that expression of CTIP2 is increased in SCC relative to a corresponding normal sample. Also included are kits for detecting SCC, as well as methods for identifying CTIP2 inhibitors. | 01-21-2010 |
| 20080275655 | Database supported nanocrystal structure identification by lattice-fringe fingerprinting with structure factor extraction - Candidate structures for nanocrystal and other specimens are obtained based on a specimen complex spectrum that is determined as a Fourier transform of a phase-contrast electron micrograph. The specimen can also be assessed based on an amplitude portion of the complex spectrum using a lattice-fringe fingerprint. In some examples, the specimen complex spectrum is compensated based on an electron microscope transfer function, a specimen tilt, or based on other crystallographic compensation. Amplitude or phase portions of the compensated complex spectrum can be compared with reference structures stored in one or more reference structure databases. | 11-06-2008 |
