Abstract: An apparatus for automatically extruding and forming a finished concrete channel in a drainage ditch. The apparatus includes a frame having support rails for positioning the apparatus over a drainage ditch. A concrete-receiving hopper is attached to the frame for delivering received concrete into the ditch to be shaped into a channel form. A mold having a projection to define a concrete surface of the channel is positioned beneath a top portion of the frame and configured to be received in a hollow mating portion of a laterally-reciprocating piston to shape the received concrete. A lever driver drives the reciprocating piston through a mechanically-linked motor. A vibrator cooperates with the concrete-receiving hopper to urge received concrete into the ditch to be shaped by the mold.

A single-layer hard coating is bonded to the first and/or second surface of the ultrathin tempered glass foldable substrate without an adhesive layer. The hard coating includes at least one silsesquioxane having a silicon-oxygen core framework directly bonded to the ultrathin tempered glass foldable substrate. The impact resistance defined by a maximum pen drop height without glass failure is at least four times greater than the ultrathin tempered glass foldable substrate without the hard coating.

Abstract: A quasi-solid-state battery formed from non-gas evolving in-situ curing of a quasi-solid-state electrolyte that includes a high swelling polymer made from a monomer with good compatibility with liquid electrolytes, and has a good reactivity for facile non-gas evolving in-situ polymerization. The monomer can be based on acrylate polymerization chemistry or an allyl group polymerization chemistry. Non-gas evolving initiators are used for non-gas evolving in-situ polymerization of acrylate or allyl monomer-based QSE. The resulting QSE additionally has high ionic conductivity, allowing for a high battery output, and a wide electrochemical window (stable for lithium metal anode and high-voltage cathodes). The resulting quasi solid electrolyte battery is not only easy to fabricate using conventional battery manufacturing practices, the non-gas evolving in-situ polymerization causes the QSE to be uniformly distributed within the battery, ensuring high-quality, safe battery performance and longevity.

Abstract: An inedible and dry dormant state encapsulated probiotic core-shell particle for external, non-mucosal skin application is provided. From inside out, the core-shell particle has a structure of a carrier particle core serving as a nutrient source for probiotics, a first layer including a dormant probiotic species for affecting epidermal biome and at least one prebiotic as a food source for the probiotic, a polymer layer positioned over the first layer, and a dissolvable protective layer for protecting the probiotic core-shell particle from oxidation, heat and humidity. By co-applying with a releasing medium, the dissolvable protective layer and the polymer layer are dissolved to expose the dormant probiotic containing layer, the first layer. Further, the releasing medium also is able to activate and reconstitute the dormant probiotic to a live probiotic on the applied non-mucosal epidermal surface.

Abstract: A multimode immersion cooling system includes a first, single-phase immersion cooling mode and a second, two-phase immersion cooling mode. The system operates in a single phase mode and reserves a two-phase mode for peak energy consumption periods. A single thermal transfer fluid is used for both modes, remaining in a liquid phase in a first single-phase immersion cooling mode and vaporizing when the thermal transfer fluid temperature reaches its boiling point in a second two-phase immersion cooling mode. A heat exchanger extracts thermal energy from heated thermal transfer fluid in the single phase mode while a condenser cools vaporized thermal transfer fluid to condense the vapor during the second, two-phase immersion cooling mode. A controller determines whether the multimode immersion cooling system operates in the single-phase mode or the second two-phase mode, or both.
