An embodiment provides an ionic polymer device comprising two extended electrode layers comprising a plurality of conductive particles, wherein the plurality of conductive particles form a concentration gradient in each of the two extended electrode layers, an ionic polymer dielectric layer between two extended electrode layers, and at least one conductive layer on outer surfaces of two extended electrode layers. Another embodiment provides an ionic polymer device comprising a polymer composite with a plurality of surface features on two opposite surfaces, and at least one conductive layer on each of said two opposite surfaces. One embodiment provides a method of making an ionic polymer device, comprising forming a partially cured polymer-metallic salt layer, reducing the metallic salt to form a plurality of metal particles, thereby forming a first extended electrode layer and a second extended electrode layer at and near opposite surfaces of the ionic polymer device.

The present invention relates to the field of genetic engineering, particularly to phytase variant YeAPPA having improved pepsin resistance and acid resistance, and increased catalytic efficiency, by substituting Leucine at the 162th site of the sequence set forth in SEQ ID NO.1 with glycine or proline or substituting glutamic acid at the 230th site of the sequence set forth in SEQ ID NO.1 with glycine, proline or arginine, in the benefit of the development of economical feed enzyme industry.
摘要:
A simple method to introduce microstructures to the surface of elastomeric materials such as silicone elastomers is described. The patterns are generated by forming microdroplets of a protective polymer onto a silicone elastomer film, hardening the polymer, and then removing the uncoated material by chemical etching. Cell attachment study results show that the treated material has a significantly enhanced biocompatibility compared to a non-treated control.
