Abstract: A search engine of a data exchange may receive a query comprising a set of search terms, retrieve a plurality of data listings based on the search terms of the query, compare a first embedding generated by a large language model (LLM) from the search query to second embeddings generated by the LLM for each of the plurality of data listings to determine a respective relevance for each of the plurality of data listings to the search query, and rank the plurality of data listings based on the respective relevance for each of the plurality of data listings to the search query.

Abstract: This invention relates to the use of chlorite-based antimicrobials in a manner where the time of biocidal activity is extended for the microbial control in the water used for drilling, completion and remediation of wells. The invention involves mixing of a compatible extender in the form of sodium chlorate with sodium chlorite to form an antimicrobial formulation. This combination is used with an acid on the site to generate chlorine dioxide which is injected into the water used for hydraulic fracturing or remedial workover. The formulation is a much more effective bactericide for the subterranean oil and gas rich formations. The potency and longevity of biocidal activity is controlled by varying the ratios of chlorate and acid which provide different profiles of the antimicrobial activities.

Abstract: A system and method is provided for producing and delivering a product. The system includes a chamber having an inlet end, an outlet end and quenching points positioned therebetween. The inlet end is configured to receive a plurality of precursors and the quenching points are configured to receive water to obtain quenching of the reaction in the chamber thereby providing varying concentration of the resultant product.

Abstract: A semiconductor wafer inspection system includes a camera and two or more illuminators. The illuminators illuminate a line of the semiconductor wafer in sequence and the camera captures an interleaved image of illuminated lines such that the individual images can be recovered from the interleaved image. The semiconductor wafer can be moved by a conveyor so that adjacent lines can be sequentially illuminated by the illuminators. The camera may include two or more line sensors.

Abstract: Methods and apparatus are presented to measure the photoluminescence of incoming wafers and extract parameters such as minority carrier life time, diffusion length, and defect density that may be used to predict final solar cell efficiency. In some examples, illumination light is supplied to a side of an as-cut silicon wafer and the induced luminescence measured from the same side and the opposite side of the wafer is used to determine an indication of the minority carrier lifetime. In another example, the luminescence induced by two instances of illumination light of different wavelength is used to determine an indication of the minority carrier lifetime. In another example, the spatial distribution of luminescence intensity over an area surrounding a focused illumination spot is used to determine an indication of the minority carrier lifetime. Other apparatus useful to passivate the surface of a wafer for inspection are also presented.

Abstract: An hydraulic proportioning system having a fluid actuated motor with a driven motor shaft, the motor being in fluid communication with and powered by a fluid source. A pump is provided having a drive shaft driven by the driven motor shaft of the fluid actuated motor, and a drive clutch interconnecting the driven motor shaft and the drive shaft of the pump. An injector manifold is in fluid communication with the pump which is connectable to a chemical source. A tube is in fluid communication with the injector manifold and extends into a chamber having fluid communication with the fluid source, the chemical and fluid from the fluid source combining in the chamber and discharged therefrom.

Abstract: A chemical generator having inlets for receiving multiple reactant and water streams; a dilution chamber; a reaction chamber operably connected to the inlets and to the dilution chamber; an eductor operably receiving the water stream from the one of the inlets and communicating with the reaction chamber for drawing first and second reactant streams into the reaction chamber for mixing. Float control valves interrupt the water stream to the eductor when desired amounts of the first and second reactant streams have entered the reaction chamber, the eductor drawing the activated solution of first and second reactant streams from the reaction chamber into the dilution chamber. The float control valves limit the residence time of the first and second reactants in the reaction chamber and selectively interrupt flow of the water stream into the dilution chamber.

Abstract: Expanded amorphous aluminum silicate (EAAS) is used as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbially contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO2 release is very slow and over an extended period.

In one embodiment, the method includes mixing amorphous calcium silicate impregnated with a chlorite salt to form a reactant, combining the reactant with an activator to form the composition, and applying the composition to the treatment area. The present invention also includes the preparation of a product usable as a disinfectant and deodorizer, wherein the product includes a mixture of an amorphous and a chlorite salt and wherein the product is packaged as a tablet, permeable sachet, or a permeable patch attachable to a plastic bag. The present invention may also be applied using several methods to reduce the spoilage of produce. The present invention further includes a method for producing chlorine dioxide in accordance with a step-function release profile.

Abstract: An important and central aspect of the present invention is the use of expanded amorphous aluminum silicate (EAAS) as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO.sub.2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbally contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield chlorine dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO.sub.2 release is very slow and over an extended period. Under most conditions, a more rapid release of ClO.sub.
