A material flow control system. In one embodiment, the flow control system includes an elongated flow control body, the body having an axial passage therethrough, wherein the axial passage is in communication with a heat exchanger and in communication with low temperature storage. Each of a plurality of fingers are received in an opening passing through the flow control body into the axial passage, each opening at an angle to the axial passage, wherein the plurality of fingers together form a nozzle for passage of heat transfer material therethrough. A mechanism actuates movement of each of said plurality of fingers in said elongated flow control body.

A gas logging system may include a data logger comprising an enclosure, a processor, and memory. The processor and the memory may be configured to log data associated with soil. The gas logging system may further include a set of probes. A probe of the set of probes may include a sensor enclosure, at least one gas sensor configured to provide the data associated with the soil to the processor and the memory, a gas-permeable water-impermeable membrane, a solid-state dehumidifying membrane, and a fan.

A system may include an optoelectronic semiconductor device including a semi-conductive substrate, an insulative layer, a photo-active layer, a source electrode, and a drain electrode. The system may further include a light source configured to selectively apply light to a surface of the photo-active layer, where the light excites electron-hole pairs within the substrate and the photo-active layer enabling an electrical current to pass between the source electrode and the drain electrode, where the presence of a chemical substance in proximity to the surface of the photo-active layer alters the electrical current in the presence of the light, and where measurement of the electrical current during application of the light enables the chemical substance to be identified.

Using nucleotide architectures to very closely and precisely place chromophores on a nucleic acid template to form dye aggregates that produce quantum coherent excitons, biexcitons, and triexcitons upon excitement to create excitonic quantum wires, switching, and gates that would then form the basis of quantum computation. Creating the various excitons and controlling the timing of the excitons would be performed using light of the corresponding wavelength and polarization to stimulate the corresponding chromophores.

The present disclosure relates to a nontoxic poly(ethyl cyanoacrylate) (PECA) plastic. The PECA-based plastic is sourced from non-petroleum feedstocks and can be thermally and/or mechanically converted back to the ethyl cyanoacrylate monomer in a closed-loop recycling system with high monomer recovery. The disclosure also provides for methods of making the PECA plastics and methods of recycling the PECA plastics.

A system may include a web server to receive an input associated with a first user, where the input includes an assessment question and associates the assessment question with a rubric, where the rubric includes a set of criteria, where each criterion of the set of criteria includes a description and a scale with a set of scale values. The system may further include a media server to receive an audiovisual input associated with a second user. The web server may be further configured to generate an evaluation tool accessible by the first user, where the audiovisual recording is embedded in the evaluation tool, and where the evaluation tool further includes a transcript of the audiovisual recording, an analysis of communication metrics associated with the audiovisual recording, and the rubric. The media server may also enable streaming of the audiovisual recording embedded in the evaluation tool.

A device may include a substrate and an oscillation circuit integrated with the substrate. The oscillation circuit may include a field-emission-based vacuum transistor. The oscillation circuit may also include a capacitive transducer. An oscillation frequency of the oscillation circuit may be indicative of a magnitude of a temperature, a pressure, or a vibration at the capacitive transducer.

A system may include a substrate and an array of unit cells for a multi-cell antenna printed on the substrate. Each unit cell may include a first trace having an outer perimeter that forms a cross shape and an inner perimeter that encloses an area within the first trace. Each unit cell may further include a second trace having an outer perimeter that is completely enclosed by and does not contact the inner perimeter of the first trace. Each unit cell may also include a varactor electrically connecting the first trace to the second trace. A method may include receiving an electromagnetic signal at the array of unit cells and controlling a capacitance of the varactor of each unit cell to result in one or more directed beams.

The present disclosure is directed to designing dyes and methods to alter the parameters controlling the dipole-dipole coupling of dyes bound to a nucleotide oligomer architecture, which are used to propagate excitons for use in next generation room temperature quantum information systems. The disclosed dyes and methods are directed to changing the dye stability, symmetry, overlap, and steric hindrance of the dyes to fine tune aggregate systems.

A compression-resistant container may include a wall at least partially enclosing a volume, where a shape of the wall includes a set of spheroidal surfaces having at least a first spheroidal surface and a second spheroidal surface. The shape of the wall further includes a set of cylindrical surfaces having at least a first cylindrical surface. The first cylindrical surface may adjoins at least the first spheroidal surface and may be positioned between the first spheroidal surface and the second spheroidal surface.
