  • 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 Pennsylvania and Lehigh University thinks it has an answer, inspired by one......

  • 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 body. A new material, however, relies instead on a magnetically-responsiv......

  • 'Ant bridge'-inspired nanoparticle assembly fixes broken electrical circuits
    Colonies of social insects are capable of self-organizing and accomplishing complex tasks through individual interactions. For example, to march across large gaps, ants grip the bodies of each other, forming a living bridge that allows the colonies to reach the other side. Inspired by t......

  • How particles arrange themselves into complex structures
    Complexity in nature, whether in chlorophyll or in living organisms, often results from self-assembly and is considered particularly robust. Compact clusters of elemental particles can be shown to be of practical relevance, and are found in atomic nuclei, nano particles or viru......

  • 3D nanofabrication by volumetric deposition and controlled shrinkage of patterned scaffolds
    Lithographic nanofabrication is often limited to successive fabrication of two-dimensional (2D) layers. We present a strategy for the direct assembly of 3D nanomaterials consisting of metals, semiconductors, and biomolecules arranged in virtually any 3D geometry. We used hydrogels as scaffolds for vol......
