Abstract: Coatings and compositions are provided for coating particulates that can be used as, for example, as proppants. The proppants can be used, for example, to extract oil and gas from subterranean formations.

Abstract: Embodiments disclosed herein provide coated particles that can be used, for example, in the extraction of oil and gas from subterranean formations.

Abstract: Coatings and compositions for coating particulates are described that can be used as, for example, as proppants to, for example, extract oil and gas from subterranean formations. The coatings can be, for example, an inner coating adjacent to the particulate comprising a polyurethane and an outer coating comprising an polyurethane dispersion; a coating comprising a polyurethane admixed with a polyurethane dispersion; or a polyurethane dispersion layer and is free of an inner polyurethane layer.

Abstract: An automated website data collection method uses a hybrid web crawler strategy to obtain a probability distribution of a webpage tag of a webpage of a website to obtains an important feature of the website, and then extracts a text content of important features of the website, and forms a seed vocabulary data set using a composite semantic model. A thematic vocabulary data set having high frequency and highly representative hierarchical structure is further generated by the seed vocabulary data set, and the thematic vocabulary data can be further presented by the visualized system to show the hierarchical structure of thematic vocabulary data set.

Abstract: Treatment methods for coated or uncoated proppants that can, among other things, control fugitive dust and/or control moisture during typical handling procedures with typical transport equipment and/or add functional features to the proppant solid are disclosed herein.

Abstract: An article includes a substrate and an intumescent coating to form an intumescent product in response to heating the article. The intumescent coating is disposed on the substrate and includes a primary intumescent precursor and a layered material that includes a silicate mineral, a layered double hydroxide, or a combination thereof. The primary intumescent precursor includes a carbohydrate polymer. A process for forming an article includes forming a liquid composition by disposing in a solvent a primary intumescent precursor and a layered material, contacting a substrate with the liquid composition, and forming an intumescent coating on the substrate to form the article.

Abstract: A composite lens plate is applied in a light emitting diode (LED) lighting device having a plurality of LEDs. The composite lens plate includes a plurality of refractive elements. The refractive elements are one-to-one corresponding to the LEDs and guide light emitted by the corresponding LEDs. Each refractive element has a refractive property. The refractive elements are classified into at least two types of lenses according to the refractive property. Lenses of the same type have substantially the same refractive property, and the refractive property of lenses of one type is different from the refractive property of lenses of another type.

Abstract: Compounds of the formula provide pharmacological agents which are inhibitors of PTPases, in particular, the compounds of formula I inhibit PTP-1B and TC PTP, and thus may be employed for the treatment of conditions associated with PTPase activity. The compounds of the present invention may also be employed for inhibition of other enzymes with a phosphotyrosine binding region such as the SH2 domain. Accordingly, the compounds of formula I may be employed for prevention or treatment of insulin resistance associated with obesity, glucose intolerance, diabetes mellitus, hypertension and ischemic diseases of the large and small blood vessels.
