摘要:
A cell cultivating platform includes a substrate having a surface, at least one actuator moveable relative to the substrate, and a deformable material layer positioned above at least a portion of the supporting surface and the at least one actuator. The deformable material layer positioned opposite the substrate surface includes a biocompatible supportive surface suitable for supporting cultivated cells. The supportive surface deforms or otherwise deflects in response to activation of the at least one actuator, effectively releasing at least a portion of the cultured cells from the supportive surface. Suitable actuators include piezoelectric actuators that can be selectively energized according to one or more patterns to facilitate separation of cells from the supportive surface. Such activation cycles can be repeated.

A method for producing water-repellent treated aluminum pigment dispersion includes (a) adding a polysilazane solution in which a polysilazane is dissolved in a second organic solvent to an aluminum pigment dispersion in which an aluminum pigment is dispersed in a first organic solvent for reacting a hydroxyl group present on the surface of the aluminum pigment with the polysilazane to form a covering film on the surface of the aluminum pigment. The amount of the polysilazane in the reaction system for forming the covering film is 0.4 parts by mass or less based on 1 part by mass of the aluminum pigment, and the total addition amount of the polysilazane is from 0.2 to 0.6 parts by mass based on 1 part by mass of the aluminum pigment.
摘要:
The present technology provides compositions that may be coated on bisphenol A-containing polymers to provide a coating or film that prevents bisphenol A from leaching from the polymer. Coatings using the present compositions also protect the bisphenol A-containing polymer from degradation by UV rays and other sources. The compositions include one or more matrix polymers having a solubility parameter of about 20 or less; and a plurality of UV-blocking nanoparticles dispersed in the one or more matrix polymers; wherein the composition is substantially free of bisphenol A. Methods of making the compositions and coatings are also provided. The coatings may be used on food and beverage containers made from bisphenol A-containing polymers.
