Abstract: Disclosed herein are means and methods by which unrelated or outside entities may add value to strategic partnerships with mobile network service providers—beyond providing preexisting elevating structures. In the state of the art, mobile network service providers must rely upon multiple technicians using multiple tools to pinpoint where a tower or pole exists, and must perform precise horizontal and vertical aiming of each mobile network device when elevated and mounted at a particular position on said tower or pole. Said means and methods are directed to reducing the time and cost associated with this onsite commissioning of mobile network devices by factory wiring and factory aiming at least some of these devices in a commensurate fashion to factory wiring and factory aiming of disparate devices such as lighting fixtures.

Abstract: A method to produce coinage metal nanoparticles reduces the time and temperature of processing of previous methods. The method enables the production of significantly larger batches of high quality metal nanoparticles. A xylene-based solvent can be used to form low viscosity nanoinks from the metal nanoparticles. Aerosol deposition and inkjet printing of the low viscosity nanoinks can support feature realization in the sub-50 ?m range, useful for electronic device fabrication.

Abstract: The tris(trimethylsilyl)silanol (H-SST) ligand can be reacted with a Group 4 or 5 metal alkoxides in a solvent to form an SST-modified metal alkoxide precursor. Exemplary Group 4 precursors include [Ti(SST)2(OR)2] (OR=OPri, OBut, ONep); [Ti(SST)3(OBun)]; [Zr(SST)2(OBut)2(py)]; [Zr(SST)3(OR)] (OR=OBut, ONep); [Hf(SST)2(OBut)2]; and [Hf(SST)2(ONep)2(py)n] (n=1, 2), where OPri=OCH(CH3)2, OBut=OC(CH3)3, OBun=O(CH2)3CH3, ONep=OCH2C(CH3)3, and py=pyridine. Exemplary Group 5 precursors include [V(SST)3(py)2]; [Nb(SST)3(OEt)2]; [Nb(O)(SST)3(py)]; 2[H][(Nb(?-O)2(SST))6(?6-O)]; [Nb8O10(OEt)18(SST)2.?Na2O]; [Ta(SST)(?-OEt)(OEt)3]2; and [Ta(SST)3(OEt)2]; where OEt=OCH2CH3. When thermally processed, the precursors can form unusual core-shell nanoparticles. For example, HfO2/SiO2 core/shell nanoparticles have demonstrated resistance to damage in extreme irradiation and thermal environments.

Abstract: Lanthanide fluorinated alkoxide derivatives can be synthesized from the alcoholysis reaction of the lanthanide bis-trimethylsilyl amide and an excess amount of hexafluoro iso-propanol. Nanoparticles can be formed from the lanthanide fluorinated alkoxide derivatives by a solvothermal or solution precipitation process.

Abstract: Presented is a design of modular LED lighting fixture whereby the steps of light directing and light redirecting are independent, but cooperative, so to promote a compact fixture design with low effective projected area (EPA), good thermal properties, and a selectable degree of glare control. A lighting system employing a plurality of said fixtures is highly customizable yet has the potential to be pre-aimed and pre-assembled prior to shipping, which reduces the potential for installation error while preserving the customized nature of the fixtures.

Abstract: The present invention relates to ruggedized downhole tools and sensors, as well as uses thereof. In particular, these tools can operate under extreme conditions and, therefore, allow for real-time measurements in geothermal reservoirs or other potentially harsh environments. One exemplary sensor includes a ruggedized ion selective electrode (ISE) for detecting tracer concentrations in real-time. In one embodiment, the ISE includes a solid, non-conductive potting material and an ion selective material, which are disposed in a temperature-resistant electrode body. Other electrode configurations, tools, and methods are also described.

Abstract: A method, apparatus, and system for operating wide area lighting systems. Operating costs, as well as capital and installation costs, can be reduced by designing the lighting system for operation of individual light sources at a first “normal” operating power for a majority of the time but having the ability to boost or increase operating power for “boosted” or increased light output for the same light sources of the system for a minority of cumulative operating time of the light sources. “”In one aspect, performance data about the LED light sources is evaluated relative to whether or not the light sources will have a predicted life expectancy on the order of the entire lighting system life expectancy. Operating power levels for boosted and normal LED lumen outputs are selected to comport with predictably meeting or exceeding lighting system life expectancy.

Abstract: A lighting system is provided whereby long operating life can be reasonably ensured by taking into account requirements of the application, characteristics of the LEDs, characteristics of the fixture containing said LEDs, the desired number of operating hours, and—via developed relationships—taking an iterative approach to supplying power to the LEDs. Through the envisioned compensation methodology and effective luminaire design, a relatively constant light level can be assured for a predetermined number of operating hours (possibly longer); this is true even if operating conditions change, known behavior of LEDs proves untrue over untested period of time, or some other condition occurs which would otherwise cause end-of-life prematurely and prevent the system from meeting the desired number of operating hours.

Abstract: A method for the hydrothermal synthesis of bismuth germanium oxide comprises dissolving a bismuth precursor (e.g., bismuth nitrate pentahydrate) and a germanium precursor (e.g., germanium dioxide) in water and heating the aqueous solution to an elevated reaction temperature for a length of time sufficient to produce the eulytite phase of bismuth germanium oxide (E-BGO) with high yield. The E-BGO produced can be used as a scintillator material. For example, the air stability and radioluminescence response suggest that the E-BGO can be employed for medical applications.

Abstract: A nanosolder comprises a first metal nanoparticle core coated with a second metal shell, wherein the first metal has a higher surface energy and smaller atomic size than the second metal. For example, a bimetallic nanosolder can comprise a protective Ag shell “glued” around a reactive Cu nanoparticle. As an example, a 3-D epitaxial Cu-core and Ag-shell structure was generated from a mixture of copper and silver nanoparticles in toluene at temperatures as low as 150° C.
