    摘要: A novel material for producing auxetic foams is disclosed. The material comprises a multiphase, multicomponent polymer foam with a filler polymer having a carefully selected glass transition temperature. Novel methods for producing auxetic foams from the material are also disclosed that consistently, reliably and quickly produce auxetic polyurethane foam at about room temperature (25° C.). This technology overcomes challenging issues in the large-scale production of auxetic PU foams, such as unfavorable heat-transmission problem and harmful organic solvents.

    摘要: Improved hybrid neurovascular spheroids and methods for making the same are provided. In some embodiments of a method for making a hybrid neurovascular spheroid, the method includes i) propagating cortical cells to form a cortical spheroid; ii) propagating endothelial cells to form an endothelial spheroid; iii) propagating mesenchymal stem cells to form a mesenchymal cell culture; and iv) combining the cortical spheroid, endothelial spheroid, and mesenchymal spheroid under conditions to form the hybrid neurovascular spheroid.
