    Abstract: Nanoparticles and compositions thereof are provided for detecting and/or preventing food spoilage. Methods of making the nanoparticles and compositions, and methods of using the nanoparticles and compositions, e.g. in food packaging, are also provided. The nanoparticles can have a hydrophobic core containing a hydrophobic active agent, e.g. a hydrophobic dye and/or an antimicrobial agent, for detecting and/or preventing food spoilage. The nanoparticles can also have a copolymer of a hydrophobic polymer repeat unit, e.g. styrene or lactic acid, and a pH responsive dendrimer repeat unit. The pH responsive dendrimer repeat unit can have a pH responsive amine core having a plurality of branched acrylate arms extending therefrom. The nanoparticles can be chemically stable at neutral pH, and then release the hydrophobic active agent at a pH range indicative of food spoilage. By releasing the hydrophobic dye and/or antimicrobial agent, the nanoparticles can detect and/or inhibit food spoilage.

    Abstract: Described herein are embodiments of compositions and methods relating to three-dimensional (3D) printing. Some embodiments are directed to a composition comprising a polymer with one or more dormant functional groups. According to some embodiments, the polymer may be formed through a controlled radical polymerization method. Some embodiments are directed to a composition comprising a polymer with one or more pendent crosslinkable groups. In some cases, the composition may be used as an “ink” for 3D printing. For example, the composition may be injected into a medium. The composition and/or medium may, in some embodiments, further comprise an initiator and/or a crosslinker. After injection of the composition into the medium, the one or more dormant functional groups and/or one or more pendent crosslinkable groups may be activated, and the polymer may be crosslinked. In certain cases, the crosslinked polymer may be removed from the medium to produce a freestanding three-dimensional structure.

    Abstract: Various examples of devices, methods and systems related to pulse based arithmetic units. In one example, a pulse domain device includes an augend area calculator to provide an augend area output for an augend pulse train; an addend area calculator to provide an addend area output for an addend pulse train; a resultant sum area (RSA) decoder to provide a RSA output using the augend and addend area outputs; and a pulse timing calculator to provide RSA output pulse timing. In another example, a pulse domain device includes a multiplicand area calculator to provide an multiplicand area output for a multiplicand pulse train; a multiplier area calculator to provide a multiplier area output for a multiplier pulse train; a resultant product area (RPA) decoder to provide a RPA output using the multiplicand and multiplier area outputs; and a pulse timing calculator to provide RPA output pulse timing.

    Abstract: Methods, computer program products, and corresponding devices are provided for measuring the bi-directional reflectance distribution function (BRDF) of an object. An object is positioned relative to a BRDF measurement device. The BRDF measurement device comprises a turntable coupled to a background and a light source, the turntable configured to have the object positioned thereon; and a plurality of spectrographs configured such that each of the plurality of the spectrographs captures a reflectance spectra associated with the object from a different elevation angle relative to the object. A set of spectra data is captured by illuminating the object with the light source; and with each spectrograph, capturing a reflectance spectra associated with the object. The turntable is rotated such that an azimuthal angle between the object and the light source is changed. The capturing and rotating steps are repeated for a predetermined set of azimuthal angles.

    Abstract: Atmospheric pressure ion guides are provided. The atmospheric pressure ion guides can include a multi-ring electrode structure connecting a larger opening to a smaller opening and having a series of ring electrodes with decreasing diameter and voltage going from the larger opening to the smaller opening. The electrodes can be made from stainless steel or other suitable conductive material. The multi-ring electrode structure can be contained in a housing, such as a housing made from polyetheretherketone or other suitable thermosetting polymer. The atmospheric pressure ion guide can focus ions from an ion source for use with ion detection devices such as an ion mobility spectrometer or a mass spectrometer. Methods of using the atmospheric pressure ion guides are provided, for example to focus a plurality of ions to be injected into an ion detection device. The atmospheric pressure ion guides can increase the signal intensity of the ion detection device.
