  • Patent number: 11921493
    Abstract: Presented herein are systems and methods for automatically determining liquid coverage on plant surfaces. More particularly, in certain embodiments, presented herein is a system for receiving an image depicting one or more plant surfaces, automatically identifying the plant surfaces in the image and distinguishing portions covered by liquid, and automatically determining a liquid coverage value. In some embodiments, the system determines changes to liquid spraying parameters to achieve desired liquid coverage values. In some embodiments, the system uses two cameras to cooperatively conduct background removal in images and determination of liquid coverage.

  • Publication number: 20240047822
    Abstract: Separators and additives (e.g., electrode additives) for use in energy storage devices are disclosed. In certain embodiments, a separator includes inorganic particles. In certain embodiments, an additive includes inorganic particles. The additive may be used in an electrode, such as a cathode or anode in a battery. The inorganic particles (whether included in a separator or used in (e.g., as) an additive, for example for an electrode) may be functional inorganic particles that promote battery performance and/or safety. For example, the functional inorganic particles may act to reduce or eliminate side reactions or mitigate the effects of side reactions during electrochemical cycling of an energy storage device in which they are included (e.g., discharge and/or charge of a battery). As another example, the functional inorganic particles may additionally or alternatively promote ionic conductivity.

  • Patent number: 11820914
    Abstract: Embodiments described herein relate generally to systems and methods for creating durable lubricious surfaces (DLS) via interfacial modification. The DLS can be prepared via a combination of a solid, a liquid, and an additive that modifies the interface between the DLS and a contact liquid, resulting in an interfacial layer that acts as a lubricant and/or protective coating between the DLS and the contact liquid. The lubricating effect created between the additive and the contact liquid results in enhanced slipperiness, as well as the protective properties that can help with durability of the DLS.

  • Publication number: 20180197686
    Abstract: In certain embodiments, the invention relates to an electrochemical device having a liquid lubricant impregnated surface. At least a portion of the interior surface of the electrochemical device includes a portion that includes a plurality of solid features disposed therein. The plurality of solid features define a plurality of regions therebetween. A lubricant is disposed in the plurality of regions which retain the liquid lubricant in the plurality of regions during operation of the device. An electroactive phase comes in contact with at least the portion of the interior surface. The liquid lubricant impregnated surface introduces a slip at the surface when the electroactive phase flows along the surface. The electroactive phase may be a yield stress fluid.
