Abstract: Disclosed is a process for producing graphene from solid hydrocarbons including biomass and coal. The disclosed method does not require the presence of hydrogen and does not operate under a vacuum. The method begins by converting biomass to a graphene precursor while coal is used as is. Subsequently, the method grinds the graphene precursor to provide a desired particle size. The particles of graphene precursor (biocoal or coal) are converted to graphene by catalytic conversion on metallic foil under atmospheric conditions and in the absence of hydrogen.

Abstract: Disclosed is a limonene-sulfur polysulfide and methods for preparing the same. The polysulfide prepared according to these methods is flexible, moldable and otherwise capable of being formed in any manner consistent with a thermoplastic polymer. The limonene-sulfur polysulfide has been demonstrated to sequester inorganic palladium and inorganic mercury dissolved in water.

Abstract: The present invention provides for analysis of cyber-physical systems with relation to compliance requirements such as regulatory compliance, maintenance compliance and safety compliance. Generally, the invention provides for a set of paths from an initial state to an end state, and analyzing the paths to determine which ones contain a violation state. Based on the resultant paths test scripts are generated. Additionally, other compliance related procedures can be performed utilizing the path analysis.

Abstract: A system and method for creating a controlled geyser well with sustained periodical production includes a cap (16) which prevents gas from entering a well tubing (14) while allowing liquid to enter and accumulate in the tubing, means for compressing the gas, and means for injecting the gas in the annulus so that the gas enters the bottom end of the well tubing (14), thereby creating a controlled geyser effect which blows out most of the liquid residing in the well tubing (14). The gas being compressed can be a produced gas or a supplied gas

Abstract: Flow restriction differential pressure and a third tap differential pressure for a pipe are used to determine a pressure loss ratio for the pipe/system that includes a flow restriction. The pressure loss ratio is used to determine whether liquid is present in the pipe. If liquid is present in the pipe, a value of the Lockhart-Martinelli parameter is determined and used to (1) correct gas flow measurement for the pipe and (2) determine a liquid flow rate in the pipe.

Abstract: A photovoltaic retrofit device for a concentrating solar thermal power plant having a parabolic trough reflector, and a fluid receiver with working fluid therein spaced from the reflector and positioned at a focal point of the reflector. The photovoltaic device includes a plurality of adjustable angle dichroic mirrors positioned between the parabolic trough reflector and the fluid receiver. A photovoltaic receiver assembly has multiple photovoltaic panels in angular relationship to each other. A photovoltaic temperature regulating system includes a fluid medium to regulate temperature of the photovoltaic panels.

Abstract: A method for creating devices facilitating secure data transmission, storage and key management. At least two devices are each comprised of at least part of a physically unclonable function unit originally shared by the at least two devices on a single, monolithic original integrated circuit. The process includes physically segmenting the shared physically unclonable function unit between the at least two devices. The at least two devices which share the single, monolithic integrated circuit are physically separated into individual device units.

Abstract: Impedance is used to determine the performance of paraffin inhibitors in oil containing paraffin. The method and system can use a specially designed impedance cell having a cell constant of less than 1 cm−1. Further, the method can include obtaining at least impedance measurements above the wax appearance temperature (WAT) for an oil sample treated with a paraffin inhibitor and an oil sample not treated, and impedance measurements below the WAT for the treated oil sample and the untreated oil sample. Thereafter, the impedance measurements are correlated to determine paraffin inhibitor performance.

Abstract: An annular axial mixing system for combined gas and liquid flow. The system includes a gas-liquid separator to separate a multiphase gas and liquid into a gas flow and a liquid flow. A lower leg in communication with the gas-liquid separator is configured to receive liquid flow. An upper leg in communication with the gas-liquid separator is configured to receive gas flow. An annular mixing chamber receives gas from the upper leg. A static liquid chamber, at least a portion of which is within the mixing chamber, is in communication with the lower leg and includes perforations therein to receive gas bubbles from the gas in the annular mixing section chamber in order to mix the flows.
