摘要： The planchet holder for electrodeposition of materials includes a container cover configured to securely fit over the mouth of a beaker. An elongate suspension post passes through a through-hole in the cover a predetermined distance, and a holder assembly is coupled to the suspension post to be suspended within the beaker at a select height from the bottom of the beaker. A planchet receptacle extends axially from a body of the holder assembly, and a substrate recess is formed at a distal end of the planchet receptacle for selective placement of a planchet. An endcap is secured onto the planchet receptacle to securely capture the planchet, and a port in the endcap exposes one face of the planchet for electrodeposition of a material. The planchet holder holds the planchet stationary within the beaker and exposes only one face for electrodeposition and subsequent analysis, thereby reducing time and costs.

摘要： The bore hole tracer injection apparatus is a mechanical device for inserting a tracer agent into a bore hole at a predetermined depth. Outer and inner cylinders have side ports, with the side ports of the cylinders misaligned to prevent fluid escape from the inner cylinder until desired. The bottom of the inner cylinder includes a filler passage. A line passes through the top of the outer cylinder and attaches to a rod across the top of the inner cylinder, above the closed top thereof. The inner cylinder is filled with a tracer agent, and the apparatus is lowered into the bore hole to the desired depth. A weight is then dropped down the line, and jars the outer cylinder down around the inner cylinder when it contacts the top of the outer cylinder. This aligns the side ports of the cylinders to allow escape of the tracer agent therefrom.

摘要： The gelling agent for water shut-off in oil and gas wells is a composition that forms a gel to reduce or eliminate the flow of water in a gas or oil well. The composition is formed by mixing polyvinyl alcohol, a polyvinyl alcohol copolymer, or mixtures thereof with an amino-aldehyde oligomer, such as urea formaldehyde or melamine formaldehyde, with or without a cross-linker. The polymer composition can be used to minimize or completely shut off excess water production with insignificant reduction in hydrocarbon productivity.

摘要： The fluid expansion engine uses a liquid working fluid contained by primary pressurized cylinders. A heat exchange system alternately cycles hot and cold through the primary pressurized cylinders. As a result, the liquid working fluid in the cylinders reciprocally expands and contracts. The work done by the fluid expansion engine is extracted via a hydraulic pump and gearbox connected to secondary pressurized cylinders attached to the primary pressurized cylinders.

摘要： The apparatus for measuring performance of a suspension for cooling a computer processing unit is a measurement and testing tool allowing for the fabrication of new suspensions, and measuring and testing their short-term and long-term thermal performance in real time on any liquid-cooled computer processing unit. The suspension is prepared in a sample receiving reservoir and pumped across the unit, and then input to an air-cooled heat exchanger for recirculation back to the sample receiving reservoir. Temperatures of the working fluid are measured between the sample receiving reservoir and the computer processing unit, between the unit and the heat exchanger, and after output from the heat exchanger. Pressure differentials of the working fluid is measured across the computer processing unit and across the heat exchanger.

摘要： The bioorganic soil conditioner includes biochar derived from plant waste and a mix of chemicals including sulfonated naphthalene formaldehyde, urea-formaldehyde and polyvinyl alcohol. The bioorganic soil conditioner is made by infusing biochar from lignin-rich plant waste with the mix of chemicals. The bioorganic soil conditioner improves soil aggregation and moisture and nutrient retention capacity. Thus, the bioorganic soil conditioner may be added to soil to improve crop production and stabilize soil, for example, in conditions of high wind or desertification.

摘要： The method for damping ocean waves in a coastal area uses a barrier having a plurality of vertical walls positioned parallel to one another, each wall defining a plurality of horizontally extending slots. The dimensions of the slots, or overall porosity of the wall, and the number of walls positioned in parallel may be varied to provide different levels of damping. Accordingly, a desired amount of damping may be provided through varying the porosity of the walls and the number of walls. The method defines a transmission coefficient equal to the wave height of waves transmitted from the barrier divided by the wave height of waves incident on the barrier, and collects experimental data normalized with the significant wave height and the wavelength at the peak period for the depth of water to select the combination of wall number and porosity to produce the desired damping.

摘要： The device and method for measuring the effect of soiling on a photovoltaic device includes a device in which a photovoltaic device (reference solar cell, solar cells, PV module, etc.) may be shifted between partially and fully enclosed compartments in quick succession for measurements of the same device (1) when directly exposed to illumination or solar radiation; (2) when placed under a glass or transparent cover maintained cleared or cleaned of soil; and (3) when placed under glass or transparent cover left exposed to natural outdoor soiling, or attenuated using simulated soil that is not periodically cleaned. The measurements may be of short circuit current (Isc), maximum power (Pmax), or other electrical parameter conventionally used to evaluate performance of the photovoltaic device. A soiling ratio calculated as: SR Pmax = 1 - P max 2 - P max 3 P max 1 or calculated as: SR Isc = 1 - I sc 2 - I sc 3 I sc 1 may be used to compare or monitor performance of the photovoltaic device between measurement cycles.

摘要： The method of making a nanocomposite polyelectrolyte membrane is a process for forming membranes for use in hydrogen and methanol fuel cell applications, for example. A hydrophobic polymer, such as polypropylene, is blended with a nanofiller, such halloysite nanotubes (HNTs) or propylene-grafted maleic anhydride nano-layered silica (Ma-Si), to form a dry mix, which is then pelletized for extrusion in a twin-screw extruder to form a thin film nanocomposite. The thin film nanocomposite is then annealed and cold stretched at room temperature. The cold stretching is followed by stretching at a temperature ranging from approximately 110° C. to approximately 140° C. The nanocomposite is then heat set to form the nanocomposite polyelectrolyte membrane. The nanocomposite polyelectrolyte membrane may then be further plasma etched and impregnated with a sulfonated polymer, such as sulfonated melamine formaldehyde, a polycarboxylate superplasticizer or perfluorosulfonic acid.
