Nanocomposite photonic structures for solid state lighting
InactiveUS7259400B1Quality improvementHigh color rendering indexDischarge tube luminescnet screensCathode ray tubes/electron beam tubesPhosphorNanoparticle
A photonic structure for “white” light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent nanocomposite matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The phosphors dispersed in the matrix may be nanocrystalline, or larger sized with the addition of non light emitting, non light scattering nanoparticles dispersed within the matrix material so as to match the index of refraction of the matrix material to that of the phosphors. The nanocomposite matrix material may be readily formed by molding and formed into a variety of shapes including lenses for focusing the emitted light. A large number of the photonic structures may be arranged on a substrate to provide even illumination or other purposes.

Laser desorption ion source
ActiveUS20050056776A1Efficient extractionImprove ionization efficiencyElectron/ion optical arrangementsIsotope separationPhysicsIonization
Atmospheric pressure, intermediate pressure and vacuum laser desorption ionization methods and ion sources are configured to increase ionization efficiency and the efficiency of transmitting ions to a mass to charge analyzer or ion mobility analyzer. An electric field is applied in the region of a sample target to accumulate ions generated from a local ion source on a solid or liquid phase sample prior to applying a laser desorption pulse. The electric field is changed just prior to or during the desorption laser pulse to promote the desorption of charged species and improve the ionization efficiency of desorbed sample species. After a delay, the electric field may be further changed to optimize focusing and transmission of ions into a mass spectrometer or ion mobility analyzer. Charged species may also be added to the region of the laser desorbed sample plume to promote ion-molecule reactions between the added ions and desorbed neutral sample species, increasing desorbed sample ionization efficiency and / or creating desired product ion species. The cycling of electric field changes is repeated in a timed sequence with one or more desorption laser pulse occurring per electric field change cycle. Embodiments of the invention comprise atmospheric pressure, intermediate pressure and vacuum pressure laser desorption ionization source methods and devices for increasing the analytical flexibility and improving the sensitivity of mass spectrometric analysis.

InactiveUS20100269990A1Reduce inhibitionReduce extractionCellulosic pulp after-treatmentBiofuelsFiberLignocellulosic biomass
A process for separating the components of lignocellulosic biomass for the purpose of producing a pure reactive cellulose is disclosed. The process has two stages. In the first stage, the lignocellulosic biomass is pretreated with steam, with or without an acid catalyst, and then pressed, with or without the presence of an eluent, to remove hemicellulose and other impurities. In the second stage, the pretreated biomass is extracted with a solvent such as ethanol with or without acid catalysts in order to remove lignin and release a purified cellulose stream. The extracted cellulose is then rapidly decompressed to rupture the fibrous structure. The process provides a purified cellulose stream that is relatively easy to hydrolyze with enzymes and ferment to biofuels and other chemicals such as ethanol.
