  • Publication number: 20200030525
    Abstract: An inverted battery device has a pair of electrodes, first and second volumes, and an electrical conductor. One of the pair of electrodes is configured as an anode and the other is configured as a cathode. A first electrolyte solution and the anode are disposed in the first volume, while a second electrolyte solution and the cathode are disposed in the second volume. The electrical conductor extends between the first and second volumes to couple the pair of electrodes to each other such that electrons travel between the pair of electrodes. The device is constructed to produce ions rather than electrons such that an ionic current can be generated in a separate system, such as a biological system or other ionic system, when coupled between the anode and cathode.

  • Patent number: 10480126
    Abstract: Wood fibers possess natural unique hierarchical and mesoporous structures that enable a variety of new applications beyond their traditional use. For the first time we dramatically modulate the propagation of light through random network of wood fibers. A highly transparent and clear paper with transmittance >90% and haze <1.0% applicable for high-definition displays is achieved. By altering the morphology of the same wood fibers that form the paper, highly transparent and hazy paper targeted for other applications such as solar cell and anti-glare coating with transmittance >90% and haze >90% is also achieved. A thorough investigation of the relation between the mesoporous structure and the optical properties in transparent paper was conducted, including full-spectrum optical simulations.

  • Publication number: 20190292728
    Abstract: Solar cell substrates require high optical transparency, but also prefer high optical haze to increase the light scattering and consequently the absorption in the active materials. Unfortunately there is a tradeoff between these optical properties, which is exemplified by common transparent paper substrates exhibiting a transparency of about 90% yet a low optical haze (<20%). In this work we introduce a novel transparent paper made of wood fibers that display both ultra-high optical transparency (˜96%) and ultra-high haze (˜60%), thus delivering an optimal substrate design for solar cell devices. Compared to previously demonstrated nanopaper composed of wood-based cellulose nanofibers, our novel transparent paper has better dual performance in transmittance and haze, but also is fabricated at a much lower cost. This high-performance, low-cost transparent paper is a potentially revolutionary material that may influence a new generation of environmentally friendly printed electronics.

  • Patent number: 10411222
    Abstract: A porous base substrate is infiltrated with a polymer material to form a hybrid substrate that combines the optical advantages of both. Prior to infiltration, the base substrate may exhibit relatively low optical transmittance. For example, the base substrate may be paper, textiles, aerogels, natural wood, or any other porous material. By infiltrating the base substrate with a polymer having a similar refractive index to that of the material of the base substrate, the transmittance can thus be improved, resulting in, for example, a transparent hybrid substrate that exhibits both relatively high optical haze and relatively high optical transmittance within the visible light spectrum. The hybrid substrate can thus serve as a base for fabricating electronic devices or can be coupled to electronic devices, especially optical devices that can take utilize the unique optical properties of the hybrid substrate.

  • Publication number: 20190161840
    Abstract: A formation of multielement nanoparticles is disclosed that includes at least three elements. Each of the at least three elements is uniformly distributed within the multielement nanoparticles forming nanoparticles having a homogeneous mixing structure. At least five elements may form a high-entropy nanoparticle structure. A method for manufacturing a formation of multielement nanoparticles includes providing a precursor material composed of the at least three component elements in multielement nanoparticles; heating the precursor material to a temperature and a time; and quenching the precursor to a temperature at a cooling rate to result in a formation of multielement nanoparticles containing at least three elements and the heating and the quenching representing a multielement nanoparticle thermal shock formation process. A corresponding system for manufacturing the formation of multielement nanoparticles and a method of using the multielement nanoparticles are also disclosed.

  • Publication number: 20180369771
    Abstract: Systems and methods of synthesizing nanoparticles on substrates using rapid, high temperature thermal shock. A method involves depositing micro-sized particles or salt precursors on a substrate, and applying a rapid, high temperature thermal pulse or shock to the micro-sized particles or the salt precursors and the substrate to cause the micro-sized particles or the salt precursors to become nanoparticles on the substrate. A system may include a rotatable member that receives a roll of a substrate sheet having micro-sized particles or salt precursors; a motor that rotates the rotatable member so as to unroll consecutive portions of the substrate sheet from the roll; and a thermal energy source that applies a short, high temperature thermal shock to consecutive portions of the substrate sheet that are unrolled from the roll by rotating the first rotatable member. Some systems and methods produce nanoparticles on existing substrate.

  • Publication number: 20180356127
    Abstract: Solar thermal devices are formed from a block of wood, where the natural cell lumens of the wood form an interconnected network that transports fluid or material therein. The block of wood can be modified to increase absorption of solar radiation. Combining the solar absorption effects with the natural transport network can be used for various applications. In some embodiments, heating of the modified block of wood by insolation can be used to evaporate a fluid, for example, evaporating water for extraction, distillation, or desalination. In other embodiments, heating of the modified block of wood by insolation can be used to change transport properties of a material to allow it to be transported in the interconnected network, for example, heating crude oil to adsorb the oil within the block of wood.

  • Publication number: 20170338522
    Abstract: One or more interfacial layers in contact with a solid-state electrolyte and hybrid electrolyte materials. Interfacial layers comprise inorganic (e.g., metal oxides and soft inorganic materials) or organic materials (e.g., polymer materials, gel materials and ion-conducting liquids). The interfacial layers can improve the electrical properties (e.g., reduce the impedance) of an interface between an a cathode and/or anode and a solid-state electrolyte. The interfacial layers can be used in, for example, solid-state batteries (e.g., solid-state, ion-conducting batteries).

  • Publication number: 20170263935
    Abstract: A protection layer is formed on a highly-reactive substantially-pure metal anode to a thickness of between 1 nm and 200 nm, inclusive, using atomic layer deposition (ALD). The ALD protection layer allows the conduction of ions of the metal of the anode therethrough but suppresses electron transport therethrough. The ALD protection layer may also be effective to inhibit passage of air and/or water therethrough. The ALD protection layer can allow more relaxed purity requirements for subsequent battery assembly, electrolyte specifications, and/or cathode gas purity. Fabrication methods for the protection layers, protected metal anodes, and systems and devices incorporating such protected metal anodes are also disclosed herein.
