    Abstract: A segmented image-relay fiber can include concatenating image-relay fiber segments. Each segment can include, or consist of, an optical fiber and an imaging lens. Each segment can accurately reproduce (e.g., with little to no losses or distortion of the image) a light intensity distribution in its input plane at its output plane, while reducing the distortion of the image that occurs in many typical fiber optic image transfers. This approach can be used for a variety of applications, such as micro-endoscopy and communication transmissions that can benefit from spatially preserved information. The recorded images can also be analyzed or processed using various computational methods, including machine learning (e.g., a trained algorithm), to enhance performance.

    Abstract: Disclosed herein is a degradable polyimide substrate that may be reliably used as an electronic substrate in flexible electronics. The degradable polyimide substrate is formed via thiol-ene click chemistry reactions between diallyl imide or other alkene monomers and thiol monomers, that can be activated by photoirradiation at relatively low temperatures (e.g., about 80° C.). As a result, the degradable polyimide substrates disclosed herein may be cured using a simple, energy efficient curing process that allows for streamlined manufacturing of circuits including multilayered circuits. In some instances, epoxy monomers may be added to the monomer resin used to form the polyimide substrate, wherein selective curing may yield polymer substrates with varying degrees of flexibility and rigidity.

    Abstract: An alternative approach to producing iron from iron concentrates produced from low grade iron ore without going through pelletization and induration. Such a method may include providing iron ore concentrate in a small particle form, passing the iron ore concentrate through a moving bed conveyor reduction furnace with at least one of hydrogen or natural gas, wherein the concentrate is present in a layer that is no more than about 5 cm thick, the hydrogen gas or natural gas reducing the concentrate so as to remove oxygen therefrom, converting the iron ore concentrate to iron that has a composition similar to direct reduced iron (DRI) or sponge iron product, having about 90-95% iron, up to about 10% oxygen, with other trace impurities. Energy consumption is reduced by 30-50% and CO2 emissions are reduced by 60-95%, depending on whether natural gas or hydrogen is used.

    Abstract: The disclosure provides a human bone marrow-derived mesenchymal stem cell (hBMSC) sheet comprising one or more layers of human hBMSCs, wherein the cell sheet is prepared from a human clonal bone marrow-derived mesenchymal stem cell line generated from a single cell. The disclosure also provides methods for producing human bone marrow-derived mesenchymal stem cell sheets comprising culturing hBMSCs in culture solution on a temperature-responsive polymer which has been coated onto a substrate surface of a cell culture support, wherein the temperature-responsive polymer has a lower critical solution temperature in water of 0-80° C.; adjusting the temperature of the culture solution to below the lower critical solution temperature, whereby the substrate surface is made hydrophilic and adhesion of the cell sheet to the surface is weakened; and detaching the cell sheet from the culture support. The cell sheet may be treated with interferon gamma (IFN-γ) or basic fibroblast growth factor (bFGF).

    Abstract: A method of producing iron metal by electrolysis of iron ore can include introducing iron ore into an anode chamber. The anode chamber can include a first electrolyte and an anode. The anode can oxidize water to form O2 gas and H+ ions in the anode chamber. The iron ore can be dissolved to form Fe3+ and/or Fe2+ ions in the anode chamber. The Fe3+ and/or Fe2+ ions can be transferred from the anode chamber to a cathode chamber through a cation exchange membrane that separates the anode chamber from the cathode chamber. The cathode chamber can include a second electrolyte and a cathode. The Fe3+ and/or Fe2+ ions can be reduced to form iron metal at the cathode.
