  • Publication number: 20200140317
    Abstract: A system and process for forming a curved glass laminate article is provided. The process and system utilizes a separation material, such as solid lubricating material and/or a spray applied separation material that Applicant has determined reduces bending dot formation during co-sagging shaping of glass sheets. The bending dot reduction provided by the separation materials discussed herein is particularly seen when the pair of glass sheets have significantly different thicknesses and/or viscosities from each other.

  • Publication number: 20200061193
    Abstract: Cross-linked shear-thinning fluids of pectic acid demonstrating increased viscosity with decreasing shear, as well as methods of producing and using the same. A shear-thinning fluid includes an aqueous solution of pectic acid cross-linked by a divalent cation is disclosed. The pectic acid may be present in an amount ranging from about 0.5 to about 3.0% (w/v), the divalent cation may be present at a concentration of from about 0.5 mM to about 7.0 mM, and the viscosity of the shear-thinning fluid increases with decreasing shear. These cross-linked shear-thinning fluids of pectic acid can be utilized for controlled release formulations, cell encapsulation, and 3D printing, and provide for an improved balance between structure fidelity/mechanical stability and cell viability.

  • Patent number: 10538452
    Abstract: Surface modification layers and associated heat treatments, that may be provided on a sheet, a carrier, or both, to control both room-temperature van der Waals (and/or hydrogen) bonding and high temperature covalent bonding between the thin sheet and carrier. The room-temperature bonding is controlled so as to be sufficient to hold the thin sheet and carrier together during vacuum processing, wet processing, and/or ultrasonic cleaning processing, for example. And at the same time, the high temperature covalent bonding is controlled so as to prevent a permanent bond between the thin sheet and carrier during high temperature processing, as well as maintain a sufficient bond to prevent delamination during high temperature processing.
