Even with defects, graphene is strongest material in the world

In a new study, researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This work resolves a contradiction between theoretical simulations, which predicted that grain boundaries can be strong, and earlier experiments, which indicated that they were much weaker than the perfect lattice.

Building 3D fractals on a nanoscale

It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating 3D fractal 'building' is formed on the micro- and nanoscale.

Magnetic monopoles erase data

A physical particle postulated 80 years ago, could provide a decisive step toward the realization of novel, highly efficient data storage devices. Scientists have found that with magnetic monopoles in magnetic vortices, called skyrmions, information can be written and erased.

Nanoengineering boosts efficiency of materials that convert waste heat to electrical energy

By engineering a semiconducting material at the level of its individual atoms, Pierre Ferdinand P. Poudeu, assistant professor of material science and engineering, has boosted its ability to convert heat into power by 200 percent and its electrical conductivity by 43 percent. That's an important combination. Improving both of these figures at the same time is a major challenge for researchers working in the field.
