Abstract: Methods, structures, devices and systems are disclosed for implementing compact (e.g., nanoscale) coaxial lasers with coaxial cavity geometries which can be used to construct various coaxial cavity lasers that can operate in single mode, at room-temperature, and produce continuous-wave lasing. The described laser systems can also operate at low-temperatures, and provide thresholdless lasing using a spectrally broadband semiconductor gain medium. The cavity of the compact lasers includes a central metal core and a hollow ring surrounding the central metal core, formed within a housing with an open terminal and a closed terminal. The open terminal is positioned to both receive pump light and output laser light, and the closed terminal includes a metal cap that encloses the central metal rod and one side of the hollow ring. The described nano cavities also include a ring-shaped gain medium section, and ring-shaped lower and upper plug sections.

Abstract: The present invention relates to affinity biosensing using polarization of light scattering of aggregated noble metallic nanostructures to determine concentration of an analyte in a test sample. This new sensing system utilizes the changes in polarized plasmonic scattering from nanostructures as the nanostructures aggregate due to binding of the analyte to a binding partner attached to the surface of the metallic nanostructure.

Abstract: Three resonance-based universal power converter topologies are disclosed. One includes a partially resonant parallel L-C link and incorporates intermediate cross-over switching circuits between the link stage and each of the input and output stages (which are constructed using unidirectional switches), thereby permitting the partially resonant circuit to be operated bi-directionally. A second includes a partially resonant series LC link in parallel with the input and output networks. A third includes a partially resonant series LC link in series between the input and output networks. The input and output networks can be formed from either bidirectional switches or a combination of unidirectional switches and intermediate cross-over switching circuits, permitting the partially resonant circuit to be operated bi-directionally.

Abstract: Provided are a novel fullerene derivative which can adsorb quickly and efficiently an allergen which may cause a pollen allergy without releasing the allergen again, does not contain a metal or the like which may cause a harmful effect to a human body, and is easily applicable, impregnable, or chemically bondable onto surface of various materials: and a process for producing the same. The fullerene derivative is characterized in that a halogen group and many hydroxyl groups are bonded directly to a fullerene nucleus. In the case that the halogen group is chlorine, the fullerene derivative can be synthesized by a partial hydroxylation of a chlorinated fullerene or a partial chlorination of a hydroxylated fullerene.

Abstract: Disclosed are optical sensing devices and methods for detecting samples using the same. The optical sensing device comprises a source unit configured to generate a polychromatic light beam containing p-polarized and s-polarized components; an interferometric unit configured to split the light beam into a probe beam passing a first path and a reference beam passing a second path and to recombine the probe beam output from the first path and the reference beam output from the second path; a sensing unit disposed in the first path to introduce a first SPR effect associated with a target sample to the probe beam; and a detection unit configured to detect target sample characteristics by obtaining an intensity spectrum of the recombined light beam. The introduction of a polychromatic light source in the optical sensing device increases the detection dynamic range and the detection sensitivity.

Abstract: A scanning apparatus, is used to effect multiple images of a tumor in which a contrast agent has been localized as a detectable marker over a selected time to map the change in the imaged marker. The rate of change in the imaged marker and/or contrast intensity of the dyed tissues is used to assess tumor aggressiveness and as an early predictor of response to cancer therapy. In particular, following the marking of tumor or cancerous tissues by the initial localization of an imageable contrast agent, the rate of change in the volume and/or area of the imaged marker is used to provide an indication of tumor interstitial fluid pressure (TIFP).

Abstract: The present invention relates to a focus-adjustable device and a system thereof, wherein the focus-adjustable device is fabricated by forming a single closed flow channel in the internal of a transparent substrate, so as to make the substrate and the single closed flow channel together form a specific lens structure similar to the Fresnel lens. In the present invention, when a light illuminates on one side of the substrate, the light would be concentrated at a specific focus point distancing from the other side of the substrate after being deflected by the specific lens structure. Moreover, a fluid having a specific refractive index can be filled into the single closed flow channel by a flow channel opening, so as to carry out the purpose of adjusting the focus of the specific lens structure; or to make the light parallelly pass through the specific lens structure without any deflection.
