简介：自己组装在自然占优势并且从自然学习将导致biofunctional材料。由弹力素的蛋白质启发了，我们在忍受重复VPGAG的肽的弹力素的超分子的hydrogel上在这研究报导了。粘弹性性质，nanostructures的形态学，并且在自我装配的nanostructure的芳香的叠被电流测定，传播电子显微镜(TEM)，和荧光显微镜分别地描绘。gelator的biocompatibility被MTT试金也证明。尽管超分子的hydrogel没能展出象弹力素一样的高弹性，thixotropichydrogel可能在房间文化的领域里为应用有潜力，控制药版本，等等。

简介：根据布郎的参数，大耳朵的蝙蝠是翼，由线和飞机做了的一个简单倾斜地截断的蝙蝠耳朵模型被设计，它数字地与有限元素方法被模仿。当频率增加了，远地的择向性的变化在举起和方位角被分析。结果显示出那，与布朗的翼相比大耳朵的蝙蝠，现在的模型在在方位角的扫描、更好的择向性和更大的角度在elevation.In增加放大的驾驶的频率的更宽的带宽有优点，基于单个底，车站能被使用驾驶的频率扫描天线完成的一个无线的放方法。
