    Abstract: Caesium-137 irradiates electronic paper. An incoming gamma-ray from the Cs-137 interacts with a particle inside a micro-container by generating a recoil electron and/or a hole. Because the recoil electron physically leaves the particle, the particle is charged depending on the dose from the radiation source. And, the charge of the particles change, which results in a movement of the particles within the micro-container. After refreshing the electronic paper, a visible difference in the gray-scale can be seen. Thus, the visible difference in the gray-scale is an effect caused by the irradiation of the electronic paper, showing sensitivity to high energy radiation--thus, non-optimized electronic paper is sensitive to high energy radiation and can be used as a radiation dosimeter. In addition, electronic paper can be used for sensing chemical and bio-chemical agents, as well as detecting high energy radiation.

The nanoparticles have a maximum dimension that is in the range from 0.1 micron to 1 millimeter, and can be sintered with pores thereamongst. A passing radiation generates electrons at one or more nanoparticles, some of which are scattered into a pore and directed toward a direction opposite to the applied electrical field. These electrons travel through the pore and collide with additional nanoparticles, which generate more electrons. The electrons are amplified in a cascade reaction that occurs along the pores behind the initial detection point. An electron amplification device may be placed behind the porous material layer to further amplify the electrons exiting the porous material layer.

  • Patent number: 8002466
    Abstract: The present invention relates to an irradiation verification apparatus containing living cell material which is fixed in location on cell supports which are arranged between cell support holders. For irradiation verification, the z co-ordinate of the irradiation verification apparatus is adjusted in the direction of the beam axis Z so that, after irradiation, regions having killed cell material can be demarcated in spatial co-ordinates, with reference to an irradiation scheme, from regions having cell material of the irradiation verification apparatus that is still active. A container having an insert for the cell supports and also the cell support holders comprise a beam-transparent material. The cell support holders have a base plate and a top plate, between which the cell supports are arranged orthogonally to the holding plates.

  • Publication number: 20110174989
    Abstract: A method of preparing a fine powder of calcium lanthanoid sulfide is disclosed. The method includes spraying soluble calcium and lanthanoid salts into at least one precipitating solution to form a precipitate comprising insoluble calcium and lanthanoid salts, optionally, oxidizing the precipitate comprising insoluble calcium and lanthanoid salts, and sulfurizing the optionally oxidized precipitate to form a fine powder of calcium lanthanoid sulfide. An alternative method for forming the powder is by flame pyrolysis. The calcium lanthanoid sulfide powder produced by either method can have an impurity concentration of less than 100 ppm, a carbon concentration of less than 200 ppm, a BET surface area of at least 50 m2/g, and an average particle size of less than 100 nm.

  • Publication number: 20110118571
    Abstract: Methods are provided for the detection of an analyte in a sample using wavelength modulated differential photothermal radiometry with enhanced sensitivity. A wavelength modulated differential photothermal radiometry system, comprising two optical modulated beams, where each beam experiences different absorption by the analyte, is calibrated by controlling the relative phase difference between the modulated beams so that individual photothermal signals corresponding to each modulated beam are 180° out of phase, corresponding to peak sensitivity to analyte concentration. The system may be further calibrated by varying the relative intensities of the two modulated beams and measuring standards containing known analyte concentration in order to determine an optimal relative intensity for a given concentration range of interest.

  • Patent number: 7936265
    Abstract: A smartcard or other media detects the presence of chemical, biological, radiation, and/or explosive (CBRE) compounds or other items of interest on individuals handling the smartcard or other media. The exposure is stored such that, when the card is presented to a reader, the detection data is transmitted to the reader for appropriate processing by the system. In one embodiment, this invention provides a detection methodology which captures the fact that the holder of the detection device has been in contact with an item of interest without external power. The detector card is then able to alert appropriate authorities of that exposure when the device is presented to a reader in the normal course of the holder's business.

  • Patent number: 7914734
    Abstract: The invention encompasses analyzers and analyzer systems that include a single molecule analyzer, methods of using the analyzer and analyzer systems to analyze samples, either for single molecules or for molecular complexes. The single molecule uses electromagnetic radiation that is translated through the sample to detect the presence or absence of a single molecule. The single molecule analyzer provided herein is useful for diagnostics because the analyzer detects single molecules with zero carryover between samples.

  • Publication number: 20110049368
    Abstract: A radiation detector includes material for absorbing incident radiation, and for providing a response to heating caused by the absorption of photons from the incident radiation. The radiation detector may include multiple pixels, each with one or more layers of absorbing material. The absorbing material may include black (microstructured) silicon, which has the advantage of being a good absorber of radiation in the short wave infrared (SWIR) wavelengths (as well as ultraviolet (UV) wavelengths and visible light wavelengths). The radiation detector may include multiple pixels, each separately responding to radiation incident on that pixel, and each including black silicon (as well as possibly other absorptive materials). The pixels of the detector may each have cantilevered attachment to a frame of the detector, with differences in coefficient of thermal expansion of materials of the pixels causing deflection of parts of the pixels due to heating from absorption of radiation.

  • Patent number: 7893409
    Abstract: A photoluminescence mapping system and method for use in fabricating solar cells that eliminates the need for complex and expensive light sources, filters and high sensitivity cameras. Generally, the method includes: (i) irradiating a surface of the substrate with radiation having a predetermined energy for a first predetermined period of time to photogenerate carriers therein; (ii) stopping the irradiation; (iii) exposing the surface of the substrate to a camera for a second predetermined period of time; and (iv) capturing with the camera a photoluminescence (PL) signal emitted from the surface of the substrate.
