Abstract: Echelle gratings and microelectromechanical system (MEMS) digital micromirror device (DMD) detectors are used to provide rapid, small, and highly sensitive spectrometers. The new spectrometers are particularly useful for laser induced breakdown and Raman spectroscopy, but could generally be used with any form of emission spectroscopy. The new spectrometers have particular applicability in the detection of improvised explosive devices.

Abstract: Systems and methods for co-enhancing contaminant degradation such as LNAPL and DNAPL degradation. Embodiments of the inventive technology may relate to assuring adequate amounts (e.g., concentrations) of certain substances (e.g., nitrogen, electron acceptor, bacteria, microbial substrate) so that degradation of LNAPL and DNAPL is enhanced as intended. Any of the inventive methods may involve the amendment of groundwater with one or more particular substance (uric acid, electron acceptors, microbial substrate, as but a few examples) in order to enhance DNAPL, and perhaps also, LNAPL degradation.

Abstract: Methods and apparatus are disclosed for possibly producing pipeline-ready heavy oil from substantially non-pumpable oil feeds. The methods and apparatus may be designed to produce such pipeline-ready heavy oils in the production field. Such methods and apparatus may involve thermal soaking of liquid hydrocarbonaceous inputs in thermal environments (2) to generate, though chemical reaction, an increased distillate amount as compared with conventional boiling technologies.

Abstract: The present invention relates to the fields of molecular biology and plant biology. Specifically, the invention is directed to the methods for expressing spider silk proteins in plants and the synthesis and purification of spider silk proteins therefrom.
Abstract: The invention is a method for the development of a platform that enables the efficient and simultaneous creation of multiple detection assays. The invention entails the use of any bacteriophage, modified to carry a reporter gene, to which any analyte-recognizing moiety is attached via the capsid. The modified bacteriophage is used to attach to the target analyte. This attachment is identified via bacteriophage amplification in a helper bacteria strain with subsequent production and detection of the reporter gene.
Abstract: A method for mitigating the deposition of wax on production tubing walls. The method comprises positioning at least one ultrasonic frequency generating device adjacent the production tubing walls and producing at least one ultrasonic frequency thereby disintegrating the wax and inhibiting the wax from attaching to the production tubing walls. A system for mitigating the deposition of wax on production tubing walls is also provided.
Abstract: At least one embodiment of the inventive technology relates to a frozen environmental sample temperature control system that comprises a frozen formulation having water in an amount from substantially 87% to 78% by weight of the formulation, and salt in an amount from substantially 13% to 22% by weight of the formulation, the system further including at least one container containing the frozen formulation; and a cooler having insulating material disposed between an outer wall and an inner surface that defines an inner chamber into which the at least one container and the at least one frozen environmental sample may be placed for storage and/or transport. Various embodiments may incorporate specific types of insulating material and/or adaptations to an inner surface of the cooler to enhance the insulation effected thereby.

Abstract: Disclosed are surfactants that contain two ionic or polar nonionic head groups, each connected to a central ionic head group by a hydrocarbon linking moiety. The central head group is a dithiophosphate, dithiocarbamate, or quaternary ammonium group. These surfactants have potential applications in chemical decontamination of mustard (simulants), storage and release devices/chemical switches and the remediation of heavy-metal ion-contaminated water.

Abstract: The invention is a method for the development of assays for the simultaneous detection of multiple bacteria. A bacteria of interest is selected. A host bacteria containing plasmid DNA from a T even bacteriophage that infects the bacteria of interest is infected with T4 reporter bacteriophage. After infection, the progeny bacteriophage are plating onto the bacteria of interest. The invention also includes single-tube, fast and sensitive assays which utilize the novel method.
Abstract: The present invention relates to methods for the rejuvenation of cupric oxide having adsorbed arsenic from arsenic contaminated water. The rejuvenated cupric oxide may be recycled to again react with and adsorb arsenic in arsenic contaminated water.
Abstract: Ultrasonic spectroscopy, calorimetry, or thermogravimetric analysis provide measures which correlate with properties of asphaltene complex of petroleum residua which can be used to establish or maintain consistent properties of petroleum residua during blending or to determine immediacy of petroleum residuea to deposition phenomena during pyrolytic thermal treatment.

Abstract: In at least one embodiment, the inventive technology relates to in-vessel generation of a material from a solution of interest as part of a processing and/or analysis operation. Preferred embodiments of the in-vessel material generation (e.g., in-vessel solid material generation) include precipitation; in certain embodiments, analysis and/or processing of the solution of interest may include dissolution of the material, perhaps as part of a successive dissolution protocol using solvents of increasing ability to dissolve. Applications include, but are by no means limited to estimation of a coking onset and solution (e.g., oil) fractionating.

Abstract: An imaging fountain flow cytometer allows high resolution microscopic imaging of a flowing sample in real time. Cells of interest are in a vertical stream of liquid flowing toward one or more illuminating elements at wavelengths which illuminate fluorescent dyes and cause the cells to fluoresce. A detector detects the fluorescence emission each time a marked cell passes through the focal plane of the detector. A bi-directional syringe pump allows the user to reverse the flow and locate the detected cell in the field of view. The flow cell is mounted on a computer controlled x-y stage, so the user can center a portion of the image on which to zoom or increase magnification. Several computer selectable parfocal objective lenses allow the user to image the entire field of view and then zoom in on the detected cell at substantially higher resolution. The magnified cell is then imaged at the various wavelengths.
Abstract: A towline fuse device for use in a towing system with a towing vehicle and a towline is provided. The towline fuse device comprises a fuse mechanism for failing at a predetermined level of tensile force, the fuse mechanism mounted between the towing vehicle and the towline wherein the predetermined level of failure of the fuse mechanism is less than the towing ratings of the towing system. The strain energy in the towline is then harmlessly dissipated in the towline fuse device.
Abstract: A device for the measuring membrane permeability in electrical/electrochemical/photo-electrochemical fields is provided. The device is a permeation cell and a tube mounted within the cell. An electrode is mounted at one end of the tube. A membrane is mounted within the cell wherein a corona is discharged from the electrode in a general direction toward the membrane thereby generating heated hydrogen atoms adjacent the membrane. A method for measuring the effects of temperature and pressure on membrane permeability and selectivity is also provided.
