    Abstract: An electrode includes a soft substrate, a metal layer in direct contact with the soft substrate, and a lithium layer formed directly on the metal layer, wherein the metal layer comprises wrinkles. The wrinkles are of a substantially uniform height, and the height is in a range of 100 nm to 20 μm. The wrinkles are typically separated by a substantially uniform distance, and the distance is in a range of 100 nm to 1000 μm. The wrinkles may be one dimensional or two dimensional. Fabricating an electrode includes forming a metal layer on a soft substrate, and forming a lithium layer on the metal layer. Forming the lithium layer on the metal layer yields uniform wrinkles in the metal layer. A battery may include the electrode as described.

    Abstract: A system for producing gas streams for use in synthetic fuel production through CO2 capture and water splitting is disclosed. The system includes a CO2 capture device configured to receive a CO2-containing stream and including an aqueous alkaline solution. The alkaline solution includes hydroxide and/or carbonate ions. The CO2 capture device generates a carbon-rich solution when the alkaline solution absorbs CO2. The carbon-rich solution includes carbonate and/or bicarbonate ions. The system also includes an electrolyzer fluidically coupled to the CO2 capture device, and defining a volume including an anode region having an anode, and a cathode region having a cathode. The volume includes an electrolyte solution having a pH gradient generated by an electric current, causing the electrolyte solution to be acidic in the anode region and alkaline in the cathode region. The carbon-rich solution is received into the electrolyzer. The electrolyzer generates hydrogen, oxygen, and CO2 streams.

    Abstract: A prosthetic device includes an internal frame assembled from multiple longitudinal members and multiple transverse members that are substantially planar in character and are arranged to be joined together. A medially arranged opening is defined in each transverse member, and is substantially registered with openings of adjacent transverse members to form a longitudinal passage, such as may be useful to receive an actuator and/or other items. At least some transverse members differ from one another in one or more of shape, length, or width. A covering member may be provided over the internal frame. Rear-facing gaps in transverse members may receive one or more elements such as dampers, batteries, or the like.
