摘要:
An electro-optic display comprises a layer of solid electro-optic material; a backplane comprising at least one electrode; and an adhesive layer disposed between the layer of electro-optic material and the backplane and adhesively securing the layer of electro-optic material to the backplane, the adhesive layer comprising a thermally-activated cross-linking agent comprising an epoxidized vegetable oil fatty acid or an epoxidized ester of such a fatty acid. The cross-linking agent reduces void growth when the display is subjected to temperature changes.

Bioengineered constructs are formed from cultured cells induced to synthesize and secrete endogenously produced extracellular matrix components without the requirement of exogenous matrix components or network support or scaffold members. The bioengineered constructs of the invention can be produced with multiple cell types that can all contribute to producing the extracellular matrix. Additionally or alternatively, one of the multiple cell types can be delivered to a site in the body via the endogenously produced extracellular matrix components to achieve various therapeutic benefits.
摘要:
A polyurethane formed from an isocyanate, a polyether diol and a polyester diol, the polyester diol having a molecular weight less than about 2000, or comprising two polyester diol segments connected by a steric hindrance group, each of the polyester diol segments having a molecular weight less than about 2000, the molar ratio of polyether diol to polyester diol being in the range of from about 1:9 to about 9:1. The polyurethane is useful as a lamination adhesive in electro-optic displays, and in components used to form such displays.
摘要:
The invention provides a solution to the problem of delivering molecules in a physiologically relevant manner to direct cell fate. For example, a Notch ligand molecule is presented in a microenvironment that mimics the environment encountered in vivo. Accordingly, the invention features a cell delivery vehicle comprising a biocompatible hydrogel or polymer and a composition that binds to a Notch receptor and methods of directing cell fate, e.g., stem cell differentiation, using such compositions.
摘要:
The present invention comprises compositions, methods, and devices for delivering angiogenic factors and signaling molecules to a target tissue, and controlling the release of these factors and signaling molecules to spatially and temporally restrict their release and dissemination, for the purpose of promoting angiogenesis in target tissues.
摘要:
An encapsulation material, intended for use in encapsulated electrophoretic displays, comprises the coacervation product of a polyanionic polymer having a vinyl main chain and a plurality of anionic groups bonded to the main chain, with a cationic or zwitterionic water-soluble polymer capable of forming an immiscible second phase on contact with the polyanionic polymer.

摘要:
An electrophoretic medium has walls defining a microcavity containing an internal phase. This internal phase comprises electrophoretic particles suspended in a suspending fluid and capable of moving therethrough upon application of an electric field to the electrophoretic medium. The average height of the microcavity differs by not more than about 5 μm from the saturated particle thickness of the electrophoretic particle divided by the volume fraction of the electrophoretic particles in the internal phase.
