• Stiffer shape-memory material utilizes magnetically-activated liquid
    While shape-memory materials do have some interesting potential applications, many of them require the application of heat in order to change shape – and that could cause problems, in temperature-sensitive environments such as the human bod......

  • Snail slime inspires reversible, super-strong glue
    The promise of reusable sticky things, from Post-it Notes to Blu Tack, has never quite been fulfilled. They're just never quite as sticky the second time around, or the third. But now, a team of engineers from University of Penns......

  • 有序设计聚合物内部的应力场,调控的结构颜色
    应力发白是聚合物在受应力作用时,由于受应力区的局部折射率发生变化而产生区域发白的现象。应力发白可以是材料中微裂纹、微孔和微纤丝形成的结果。在聚合物中的局部受应力处形成微孔和微纤丝往往是一种典型的不良现象,也是造成材料失效的原因之一。常见的应力产生的微裂纹、微孔和微纤丝结构是没有规则的,所以我们看到的相当于漫反射,所以是白色的。...

  • 清华/复旦Nat. Catal.:蛋白质-高分子偶联物中合成高活性酶-金属纳米复合材料
    在酶催化和多相催化之间架起一座桥梁将为制造业提供新的耦合工业流程。然而,酶催化和多相催化反应条件的不同将会导致催化剂失活。近日,清华大学戈钧、肖海,复旦大学Richard N. Zare等多团队合作,克服了这一挑战,发展了一种合成该杂化催化剂的特殊方法。作者利用蛋白质-高分子纳米偶联物作为限域纳米反应器,原位合成了酶-Pd纳米复合材料。实验发现,合成的酶-0.8 nm Pd纳米粒子复合材料催化(S)-1-苯基乙胺外消旋化反应的活性增强。在脂肪酶最适温度55......
