Abstract: A bifunctional linker of Formula 1 wherein in Formula I, at least one of R1 to R4 is —COOR5 and R5 is —C0-C10alkyl(C2-C10alkynyl) or —C0-C10alkyl-C2-C10alkenyl(C2-C10alkynyl), preferably a terminal alkynyl. The bifunctional linker is used in a cycloaddition to tether two entities, for example a protein or antibody, and an active agent, to form a bisconjugate. The bifunctional linker also be used to form a conjugate, followed by cycloaddition in the presence of a comonomer composition to form a bisconjugate including a protein or antibody linked to an adhesive polymer network. Catalysis can be provided by a copper-containing paint on a surface to adhere the bisconjugate to the surface. Methods of synthesis and use of the bisconjugates imaging, diagnostic, and therapeutic applications are also described.

Abstract: A microcapsule includes an oxime-based polymerization product of two or more monomers and a payload. The payload may be encapsulated within the microcapsule. The oxime-based polymerization products may include an oxime-based monomer and an isocyanate-based monomer. Methods of making such microcapsules and methods of delivering a payload to a target using such microcapsules are provided.

Abstract: Methods of recycling target elements include dissolving and/or alloying a metallic component, including one or more target elements, with liquid gallium to provide a gallium melt and exposing the gallium melt with a liquid medium to form an intermediate liquid. The liquid medium is different than the gallium melt. The method also includes adjusting a pH value of the liquid medium to a first target pH and/or adjusting an applied electrical potential value to the intermediate liquid to a first target applied electrical potential, where at least a first portion of an initial total quantity of a first target element is present in a soluble form in the liquid medium. The method further includes isolating the liquid medium from the intermediate liquid to provide a first leachate, and separating the first target element from the first leachate.

Abstract: Disclosed herein is a safe and rapid reacting catalyst for polyurethane polymerization. Also disclosed herein is a method of producing the catalyst and polymerizing polyurethane. The combination of an organic polymerization initiator and an organometallic polymerization initiator leads to a safer alternative to tin-based materials.

Abstract: A method for printing a semiconductor material includes depositing a molten metal onto a substrate in an enclosed chamber to form a trace having a maximum height of 15 micrometers and/or a maximum width of 25 micrometers to 10 millimeters and/or a thin film having a maximum height of 15 micrometers. The method further includes reacting the molten metal with a gas phase species in the enclosed chamber to form the semiconductor material. The depositing the molten metal includes depositing a metal composition including the molten metal and an etchant or depositing the etchant separate from the molten metal in the enclosed chamber.

Abstract: A water harvesting device includes at least a first adsorption column including a first inlet, a first outlet, and a first interior region. A sorbent material is located within the first interior region of the first adsorption column. The sorbent material includes a metal organic framework (MOF) material including a plurality of metal ions or clusters of metal ions coordinated to one or more organic linkers, a plurality of nanofabrics comprising a hydrogel material, or a combination thereof.
