摘要： Chalcogenide waveguides with high width-to-height aspect ratios and a smooth exposed surfaces can serve as mid-infrared evanescent-absorption-based sensors for detecting and identifying volatile organic compounds and/or determining their concentration, optionally in real-time. The waveguide sensors may be manufactured using a modified sputtering process in which the sputtering target and waveguide substrate are titled and/or laterally offset relative to each other and the substrate is continuously rotated.

摘要： A method, comprising: providing a light source, a high contrast providing object, and an image acquisition device; emitting a light beam from the light source through the high contrast providing object, a transparent object and a surface of the transparent object toward the image acquisition device; exposing the surface of the transparent object to icing conditions such that a layer of ice is formed by ice accretion on the surface, wherein the light beam traverses the layer of ice after having traversed the transparent object; acquiring a series of images over time of the high contrast providing object using the image acquisition device; determining blur occurring in the series of images over the time; and quantifying the loss of visibility over the time through the transparent object on the basis of the determined blur.

摘要： This disclosure provides systems, methods, and apparatus for controlling transitions in an optically switchable device. In one aspect, a controller for a tintable window may include a processor, an input for receiving output signals from sensors, and instructions for causing the processor to determine a level of tint of the tintable window, and an output for controlling the level of tint in the tintable window. The instructions may include a relationship between the received output signals and the level of tint, with the relationship employing output signals from an exterior photosensor, an interior photosensor, an occupancy sensor, an exterior temperature sensor, and a transmissivity sensor. In some instances, the controller may receive output signals over a network and/or be interfaced with a network, and in some instances, the controller may be a standalone controller that is not interfaced with a network.

摘要： The present invention provides a sensing device for detecting an analyte containing a non-metallic element such as F. A working sensor has a 3D array of voids each having a void internal wall. The void internal walls have cavities each having a cavity internal wall made from a material containing the non-metallic element. A binding of the analytes to the cavities induces a detectable variation of the optical property of the 3D array of voids. The invention exhibits numerous technical merits such as high sensitivity, high specificity, fast detection, ease of operation, low power consumption, zero chemical release, and low operation cost, among others.

摘要： The present disclosure relates generally to a sensor chip and methods for the detection of an analyte. In particular, the disclosure relates to a sensor chip for detecting an analyte in a subject suffering from a neurodegenerative disease. The sensor chip comprises a conductive layer on a membrane support layer, wherein a plurality of apertures extend through the conductive layer and the membrane support layer and are arranged such that illumination of the conductive layer and/or the membrane support layer produces a surface plasmon resonance.

摘要： A scalable, real-time, label-free, electrode- or optical-based cell monitoring system for integration into a cell culture incubator is described herein. An example system includes (1) cell culture consumables with integrated electrodes and/or optics for growing and monitoring cells, (2) incubator trays for consumable organization and recording, and (3) a system console, external to the incubator, for connecting multiple incubator trays. Without perturbing the cell culture, the system is capable of monitoring multiple culture attributes for each cell culture consumable simultaneously. These attributes can include, but are not limited to, cell growth, proliferation, morphology, media pH, or media oxygen. The system can support multiple trays, which permits monitoring dozens to hundreds of consumables simultaneously, including a mixture of consumables of various sizes. In addition to monitoring adherent cells, the disclosed technology can be readily adapted for monitoring of cell suspensions.
