Abstract: In some examples, a method of making a filter includes heating a metal substrate to precipitate a first phase on a surface of the metal substrate from a metal alloy, the metal substrate defining a plurality of apertures configured to allow a gas to pass through the apertures. The metal substrate is the metal alloy including a first metal and a second metal. The method further includes growing a plurality of carbon nanotubes (CNTs) on the surface of the first metal of the first phase, and the CNTs are configured to capture at least one particle.

Abstract: Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.

Abstract: Improved resolution of a time-varying optical measurement is provided with optical intensity modulator(s) having a bandwidth greater than that of the detector array(s). The modulator configuration can have high photon collection efficiency, e.g. by using polarization modulation to split the incident light into several time-gated channels.

Abstract: A system for cooling an inductively coupled plasma (ICP) instrument includes: the ICP instrument; a pump in fluid communication with the instrument via a first conduit; and a micro-channel heat exchanger in fluid communication with the instrument via a second conduit, and in fluid communication with the pump via a third conduit. The pump is configured to generate a pump outlet pressure of coolant that exceeds a back pressure of the instrument such that a pressure of the coolant traveling through the second conduit and into the heat exchanger is less than or equal to 5 pounds per square inch (psi) above atmospheric pressure, as measured at an inlet to the heat exchanger.

Abstract: A system and method for utilizing Raman spectroscopy to detect and identify a fluid sample or stain in situ to determine the presence of body fluids. A portable Raman spectrometer performs stand-off Raman spectroscopy on suspected body fluids to detect and identify their actual presence, such as blood or semen. The portable Raman spectrometer can include a stand-off attachment to allow the proper distance between the spectrometer and fluid sample for optimal visual and statistical analysis of spectral data.

Abstract: A method of performing Raman spectroscopy can include guiding a Raman pump beam with an optical fiber, where the Raman pump beam inducing fluorescence in the optical fiber. The beam and the fluorescence are coupled to a photonic integrated circuit (PIC) via the fiber. The beam is used to excite a sample in optical communication with the PIC via evanescent coupling and induces Raman scattering in the sample. The Raman scattering is collected via the PIC, and the Raman pump beam as well as the fluorescence is filtered out from the Raman scattering via the PIC.

Abstract: A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.
