Abstract: An additive manufacturing apparatus includes an additive manufacturing print head and a nozzle that receives a bio-based shape memory polymer material and a bio-based material. The nozzle extrudes the bio-based shape memory polymer material and the bio-based material onto a substrate to form a bio-based shape memory polymer part or product.

Abstract: In various aspects and embodiments, the present disclosure provides methods for making glycosylated products, as well as bacterial cells and uridine diphosphate (UDP)-dependent glycosyltransferase (UGT) enzymes useful for the same. In other aspects and embodiments, the disclosure provides methods for high yield and/or high purity recovery of such glycoside products from microbial cultures or cell free reactions. In various aspects and embodiments, the disclosure provides for whole cell bioconversion processes involving the glycosylation of a desired substrate, and/or the recovery of the glycosylated product at high yield and/or high purity.

Abstract: This document describes techniques and apparatuses directed at providing a tubular band with seamless lug integration for wearable devices. In aspects, the tubular band includes an extensible strap formed of interwoven fibers. The strap includes opposing outward-facing edges at opposing longitudinal ends. Each edge defines an opening within which a base section of a coupling device can reside. The coupling device further includes an attachment section, opposite the base section, which extends from the base section outwardly through the opening to engage a coupling connector of the wearable device. When the attachment section is connected to the coupling connector, the attachment section positions an end portion of the strap adjacent the opening to engage a surface of the wearable device. In this way, the strap can be coupled to a wearable device by positioning end portions of the strap against one or more surfaces of the wearable device, forming a seamless connection between the band and the wearable device.

Abstract: A mixer for a vehicle exhaust gas system includes a mixer housing defining an internal cavity and having a mixer inlet configured to receive exhaust gas and a mixer outlet to direct exhaust gas to downstream exhaust components. A flow device is configured to receive the exhaust gas from the mixer inlet and to facilitate mixing of the exhaust gas and a reductant introduced into the first flow device. The flow device comprises a Venturi body centered on a body center axis, and the Venturi body comprises a body inlet configured to receive the exhaust gas from the mixer inlet and a body outlet configured to provide the exhaust gas to the mixer outlet. The Venturi body also includes a support flange extending from the body outlet at an offset angle to an internal edge of the mixer housing. An upstream vane is positioned within the Venturi body proximate the body inlet and is coupled to an upstream vane hub that is centered on an upstream vane hub axis.

Abstract: An exhaust component includes a housing defining an internal cavity, at least one exhaust aftertreatment component positioned within the internal cavity, and a heat exchanger. The housing has an inlet configured to receive engine exhaust gases and an outlet configured to direct the engine exhaust gasses into a tailpipe. A reductant source is associated with the housing and produces ammonia to mix with engine exhaust gases entering the exhaust aftertreatment component. The heat exchanger is positioned within the internal cavity to reduce a temperature of the engine exhaust gases exiting the outlet.

Abstract: A vehicle exhaust component assembly includes a first exhaust component, a second exhaust component downstream of the first exhaust component, and an injection system configured to inject a reducing agent into engine exhaust gases upstream of the second exhaust component. A mixer connects an outlet of the first exhaust component to an inlet to the second exhaust component. The mixer includes an outer housing that is configured to direct a mixture of the reducing agent and the engine exhaust gases into the second exhaust component. The mixer also includes at least one insulation feature that is configured to reduce heat lost at the outer housing.
