Scientists Guide Gold Nanoparticles to Form "Diamond" Superlattices

Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant arrangement may open a path to new materials that take advantage of the optical and mechanical properties of this crystalline structure for applications such as optical transistors, color-changing materials, and lightweight yet tough materials.

Graphene Shown to Safely Interact with Neurons in the Brain

Researchers have successfully demonstrated how it is possible to interface graphene - a two-dimensional form of carbon - with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson's disease.

Researchers Develop Completely New Kind of Polymer

Stupp-Hybridpolymer.jpg

Imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. Or a polymer that can contract and expand the way muscles do. These functions require polymers with both rigid and soft nano-sized compartments with extremely different properties. Northwestern University researchers have developed a hybrid polymer of this type that might one day be used in artificial muscles; for delivery of drugs or biomolecules; in self-repairing materials; and for replaceable energy sources.

Combining experimental investigations and theoretical simulations, researchers have explained why platinum nanoclusters of a specific size range facilitate the hydrogenation reaction used to produce ethane from ethylene. The research offers new insights into the role of cluster shapes in catalyzing reactions at the nanoscale, and could help materials scientists optimize nanocatalysts for a broad class of other reactions.
