  • Patent number: 11666940
    Abstract: A method of mercury-free photochemical micro-/nano-encapsulation of an active material is a process for obtaining Micro-/nano-capsules by means of curing by UV LED radiation at ambient or even cold temperatures. A stirrer photo-reactor made from glass or transparent plastics can be used but mixed flow reactor could be also employed. Appropriate mixing is sufficient to expose all droplets, which contain an active material surrounded by curable-shell materials in the emulsion to the LED radiation. Using the optimum light intensities and reactions' times is critical for encapsulating the active material with a high efficiency and producing a high quality micro-/nano-capsules, Solar monochromator device can also be used as long as it generate the same radiation with a narrow/single wavelengths as the LED device.

  • Patent number: 11612870
    Abstract: An industrially scalable microcapsule, fiber or film forming process and formulations suitable for use in conventional spray drying systems are provided. The one-step spray drying process utilizes formulations of a first ionic polymer, a second ionic polymer with an isoelectric point (pI2) or acid dissociation constant (pKa2) that is greater than the isoelectric point (pI1) or acid dissociation constant (pKa1) of the first ionic polymer and a volatile base or volatile acid. Volatilization of the volatile base or acid of the spray formulation changes the pH of the solution and changes the charge of the second ionic polymer initiating electrostatic interactions with the first ionic polymer through complex coacervation. Microcapsules formed by the complex coacervation process can stabilize bioactive components as well as control the release of the bioactive components for a variety of applications.

  • Patent number: 11613630
    Abstract: One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti jamming characteristics of the product in the hopper.
