  • Patent number: 11130277
    Abstract: Systems, apparatus and methods for producing objects with cryogenic 3D printing with controllable micro and macrostructure with potential applications in tissue engineering, drug delivery, and the food industry. The technology can produce complex structures with controlled morphology when the printed 3D object is immersed in a liquid coolant, whose upper surface is maintained at the same level as the highest deposited layer of the object. This ensures that the computer-controlled process of freezing is controlled precisely and already printed frozen layers remain at a constant temperature. The technology controls the temperature, flow rate and volume of the printed fluid emitted by the dispenser that has X-Y positional translation and conditions at the interface between the dispenser and coolant surface. The technology can also control the temperature of the pool of liquid coolant and the vertical position of the printing surface and pool of coolant liquid.

    Abstract: Described herein is a system and method for tuning light scatter in an optically functional porous layer of an LED. The layer comprises a non-light absorbing material structure having a plurality of sub-micron pores and a polymer matrix. The non-light absorbing material forms either a plurality of micron-sized porous particles dispersed throughout the layer or a mesh slab, wherein a plurality of sub-micron pores is located within each micron-sized porous particle or forms an interconnected network of sub-micron pores within the mesh slab, respectively. A polymer matrix, such as a high refractive index silicone fills the plurality of sub-micron pores creating an interface between the materials. Refractive index differences between the materials allow for light scatter to occur at the interface of the materials. Light scatter can also be decreased as a function of temperature, creating a system for tuning light scatter in both an off state and on state of an LED.

  • Patent number: 10688469
    Abstract: The invention relates to a porous hydrogel matrix having substantially interconnected tunnel-shaped micropores with a three-dimensional configuration of an interconnected hollow tetrapod network. Such matrices may be used to entrap motile cells that migrate into the micropores of said matrix. The matrices of the invention are formed by a method comprising the steps of providing a solution of a hydrogel-forming material, providing a template material with a three-dimensional configuration corresponding to the negative configuration of the desired interconnected porous structure of the hydrogel material, said template material comprising interconnected zinc oxide tetrapod (t-ZnO) networks, casting the solution of hydrogel-forming material onto the template and removing the template material from the hydrogel material by acid hydrolysis of the template material.

  • Patent number: 10661493
    Abstract: Provided is a blow-molding method capable of suppressing generation of blister-like bubbles and producing a high quality hollow molded article when forming a thick hollow molded article by blow-molding. A blow-molding method includes setting a die-slit interval in a die head according to a target wall thickness of a hollow molded article to be molded, extruding a molten resin in an accumulator into a cylindrical shape from the die slit to form a parison, and molding the parison in a mold. The die-slit interval is made smaller than a value set according to the target wall thickness at start of extrusion, and then is increased to match the value set according to the target wall thickness. The value set according to the target wall thickness is preferably corrected considering wall thickness reduction due to drawdown. The wall thickness of the hollow molded article is preferably 3.5 mm or more.
