Abstract: Provided herein are methods of making a metal-organic framework comprising: combining a pre-ligand with a metal source to provide a plurality of solid reactants; adding a solvent to the plurality of solid reactants to form a reaction mixture, wherein at least 50 wt % of the reaction mixture are the plurality of solid reactants; heating the reaction mixture wherein the pre-ligand is converted to a ligand in the reaction mixture and the ligand reacts with the metal component; and cooling the reaction mixture to produce the metal-organic framework. The present methodologies are performed without dimethylformamide in the reaction mixture. The present methods may further comprise the step of adding a crystallization aid such as zinc oxide to the reaction mixture.

Abstract: Provided are metal-organic frameworks made by the process of comprising the steps of reacting a first metal source that can generate a tetravalent metal cation in solution, a linear dicarboxylic acid, a second metal source that can generate a divalent cation in solution, and one or more monocarboxylic acid modulators in a solvent to provide a reaction solution. The reaction solution is heated to provide a metal-organic framework having between about 0 wt. % to 10 wt. % of divalent cation, surface area between about 1100 m2/g and 2700 m2/g, a porosity of between about 0.45 cc/g and 1.1 cc/g, and a relative intensity equal to or greater than 0.35 and a peak width ratio of less than 3.0.

Abstract: The present disclosure is directed to processes for forming or otherwise creating a transparent, conductive film from a heavy hydrocarbon material. It allows for what is often considered to be waste material to be transformed into a useful product, such as a heating element. Such heating elements can be incorporated into many contexts where it can be important to have transparency and/or a thin heating element, such as in windshields. The process involves dissolving a heavy hydrocarbon material in a solvent, casting the heavy hydrocarbon solution that results from the dissolving onto a substrate to form a film, and then annealing the film. The disclosure also provides for objects in which such resulting films can be used, such as Joule heaters.

Abstract: Method and systems are provided for building a structural model of the subsurface. The method may comprise obtaining discretized data that includes surfaces, polylines, points, or combinations thereof. The surfaces in the discretized data are segmented by other surfaces to form a number of segments. Each of the segments are fit to an implicit function. The implicit function for each of the segments is thresholded to create a number of implicit surfaces. The implicit surfaces are intersected to create a number of model surfaces. The structural model is then constructed from the model surfaces.

Abstract: Lost circulation particles are commonly used in drilling and/or cementing operations to prevent fluid loss to a subterranean formation. Drilling fluids and methods of drilling and/or cementing operations may also use petroleum coke lost circulation particles composed of fluid coke and/or flexicoke material. Such petroleum coke lost circulation particles may have improved transport into wellbores because of their lower density compared to traditional lost circulation material and may produce fewer fines that can interfere with lost circulation efficacy.

Abstract: A method for liquefying a feed gas stream. A refrigerant stream is cooled and expanded to produce an expanded, cooled refrigerant stream. Part or all of the expanded, cooled refrigerant stream is mixed with a make-up refrigerant stream in a separator, thereby condensing heavy hydrocarbon components from the make-up refrigerant stream and forming a gaseous expanded, cooled refrigerant stream. The gaseous expanded, cooled refrigerant stream passes through a heat exchanger zone to form a warm refrigerant stream. The feed gas stream is passed through the heat exchanger zone to cool at least part of the feed gas stream by indirect heat exchange with the expanded, cooled refrigerant stream, thereby forming a liquefied gas stream. The warm refrigerant stream is compressed to produce the compressed refrigerant stream.

Abstract: Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of high-flow polyolefin coated mineral particles (referred to as high-flow polyolefin coated mineral proppant particulates). In some instances, the high-flow polyolefin-coated mineral proppant particulates have a particle density of equal to or less than about 1.35 grams per cubic centimeter, and further may be prepared using a one-pot hot melt process.
