Abstract: Provided herein are synthetic living tissue structures comprising multiple layers of fibers deposited in solidified form from a 3D bioprinter, together with kits and methods of use related thereto. The fibers comprise a plurality of mammalian cells dispensed within a solidified biocompatible matrix. The structural integrity of the fiber is maintained upon and after deposition without any additional crosslinking. The fiber is continuously bioprinted through at least two layers of the structure. In one aspect, synthetic muscle tissue structures exhibit a readily assayable contractile functionality.

Abstract: The disclosed computer-implemented method may include identifying an application, on an electronic device, with a minimum requirement for a resource of the electronic device. The method may also include determining that an available amount of the resource of the electronic device does not meet the minimum requirement of the application. Additionally, the method may include selecting, based on the determination, an alternative user-interface mode of the application with a lower minimum requirement for the resource. Furthermore, the method may include instantiating the alternative user-interface mode of the application. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: An electrochemical apparatus includes a catholyte, an anolyte, and a separator disposed between the catholyte and the anolyte. The catholyte includes metal salt dissolved in water, thereby providing at least one metal ion. The anolyte includes a polysulfide solution. The separator is permeable to the at least one metal ion. During a charging process of the electrochemical apparatus, oxygen is generated in the catholyte, the polysulfide in the polysulfide solution undergoes a reduction reaction in the anolyte, and the at least one metal ion moves from the catholyte to the anolyte. During a discharging process of the apparatus, the oxygen is consumed in the catholyte, the polysulfide oxidizes in the anolyte, and the at least one metal ion moves from the anolyte to the catholyte.

Abstract: Electrochemical apparatuses containing electrolytes that include redox-active reactants that may be present as both a dissolved species and as a solid during a charging and/or discharging process, and related methods are generally described. The redox-active reactant may contain an active species, and the electrolyte may contain a total concentration of the active species that is greater than if the redox-active reactant were completely dissolved during an entire charging and/or discharging process. The electrochemical apparatuses described may provide relatively high energy storage capacity.
