Abstract: Methods of forming interdigitated back contact (IBC) layers are provided. According to an aspect of the invention, a first layer having alternating regions of n-type amorphous hydrogenated silicon and p-type amorphous hydrogenated silicon is formed on a second layer of intrinsic amorphous hydrogenated silicon. The first layer and the second layer are then annealed, such that dopants from the first layer diffuse into the second layer, and the first layer and the second layer crystallize into polysilicon.

Abstract: A heat exchanger includes a shell, refrigerant distributor, tube bundle, and a first baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor. The first baffle extends from a first lateral side of the shell. The first baffle is vertically disposed 5% to 40% of an overall height of the shell above a bottom edge of the shell, and extends laterally inwardly from the first lateral side by a distance not more than 20% of a width of the shell.

Abstract: A heat exchanger includes a shell, refrigerant distributor, tube bundle, and first upper baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor so that the liquid refrigerant discharged from the refrigerant distributor is supplied to the tube bundle. The first upper baffle is vertically disposed at a top of the tube bundle. The first upper baffle extends laterally outwardly from the tube bundle toward a first lateral side of the shell.

Abstract: The invention describes processes to prepare levulinic acid, formic acid and/or hydroxymethyl furfural from various biomass materials.

Abstract: Disclosed are systems, media, and methods to provide a coarse qualification process, the coarse qualification process comprising specifying filters and associated ranking characteristics for service providers, the filters comprising at least location, availability, and skills, and resolving practical concerns by displaying candidate service providers based on the filters and ranked based on the ranking characteristics; provide a qualification refinement process, the qualification refinement process comprising modifying the filters and ranking characteristics, applying the refined filters and ranking characteristics, and displaying refined candidate service providers; and provide a service provider booking process, the service provider booking process comprising resolving emotional concerns by viewing service provider video clips, wherein the time to resolve emotional concerns is less than an optimal customer review period, and resolving rational concerns by viewing service provider qualifications.

Abstract: A security device comprises a body having, a lock portion and a securing member. The lock portion may comprise a first engagement member, a second engagement member. The securing member comprises a first interface portion having a locking member, a second interface portion, and a hinge member configured to pivotally couple the first interface portion to the second interface portion. The security device further comprises an extension having a first end and a second end and comprising a head engagement section proximate the first end, and a locking member engagement portion proximate the second end. In an assembled state, the extension is configured to be coupled to the locking member engagement portion and configured to engage the first engagement member, and the second engagement member is configured to engage the locking member.

Abstract: The present disclosure is a system and method for producing a first product from a first region of an electrochemical cell having a cathode and a second product from a second region of the electrochemical cell having an anode. The method may include a step of contacting the first region with a catholyte including carbon dioxide and contacting the second region with an anolyte including a recycled reactant. The method may further include applying an electrical potential between the anode and the cathode sufficient to produce carbon monoxide recoverable from the first region and a halogen recoverable from the second region.

Abstract: Described herein is a method for identifying an aberrant feature on a nucleic acid array. In general terms, the method comprises: a) obtaining a log transformed normalized value indicating the amount of hybridization of a test sample to a first feature on the nucleic acid array; b) calculating a z-score for the first feature using: the log transformed normalized value; and the distribution of reference log transformed normalized values that indicate the amount of hybridization of control samples to the same feature on a plurality of reference arrays; and c) identifying the test feature as aberrant if it has a z-score that is above or below a defined threshold.
