Abstract: A method for preparing and applying a polyurethane adhesive comprises: mixing a part A component and a part B component of a polyurethane compound; pouring the polyurethane compound onto a first non-stick film positioned on a planar mold; placing a second non-stick film on an upper surface of the polyurethane compound; applying a pressure to the first non-stick film and/or the second non-stick film to give the polyurethane compound a specified thickness; allowing the polyurethane compound to solidify for a first period of time to form a non-tack polyurethane adhesive; cutting the polyurethane adhesive and the two non-stick films according to a size of the mating surfaces of the two objects to be joined together; placing the cut polyurethane adhesive in contact with one of the mating surfaces and hold the other mating surface in contact with the polyurethane adhesive; and heating and applying pressure to the cut polyurethane adhesive.

Abstract: Systems and methods for industrial tower packing using a high-energy laser surface processing technique are disclosed. The system includes a tower, a high-energy laser, a plurality of packing materials, and micro-sized or nano-sized structures on a packing material. The high-energy laser surface processing technique creates microscale structures that allow for high surface wettability. The high-energy laser creates micro-sized or nano-sized structures on a plurality of packing materials surfaces. The packing materials may be provided in industrial columns. The packing materials may be various shapes and sizes comprising various structures ablated into a surface of the packing materials to generate high surface area contact between a downward-flowing liquid and an upward-flowing gas. The use of a high-energy laser surface processing results in favorable super-wettable column packing material and geometry.

Abstract: Systems, apparatuses, and methods for microfluidic fluid evaporation using femtosecond laser-patterned surfaces are disclosed. A microfluidic device may comprise a femtosecond laser-patterned substrate having at least one input path and at least one output path. The femtosecond laser-patterned substrate may comprise both superhydrophobic and superhydrophilic sections. Fluid deposited at an input path may be wicked to an output path due to the surface pattern. A heating device may be provided to heat the fluid to evaporate volatiles therefrom. Vacuums and gas streams may be used to aid in volatile removal. Gas streams may add gas to the microfluidic device to react with the fluid.

Abstract: An apparatus, methods, and systems for forming microspheres comprises a furnace and an ultrasonic nozzle. The furnace has a channel and is operable to generate heat in the channel. The ultrasonic nozzle is configured to receive precursor solution and spray precursor droplets into the channel so that the heat in the channel causes the precursor droplets to form the microspheres.

Abstract: A process for forming polymer-grafted nanoparticles is provided. The process utilizes flow chemistry techniques to activate nanoparticle surfaces and then form polymer chains on the activated surfaces in a continuous process, thus avoiding the limitations and shortcomings of batch processes for forming polymer-grafted nanoparticles. The polymer-grafted nanoparticles are particularly useful as a filler or additive in fused deposition modeling (“FDM”) filaments, leading to printed parts having improved properties.
