Home > Press > 3D design leads to first stable and strong self-assembling 1D nanographene wires Schematic illustration of hierarchical structures of carbon nanofiber bundles made of bitten warped nanographene molecules. CREDIT NINS/IMS Abstract: Nanographene is flexible, yet stronger than steel. With unique physical and electronic properties, the material consists of carbon molecules only one atom thick arranged in a honeycomb shape. Still early in technological development, current fabrication methods require the addition of substituents to obtain a uniform material. Additive-free methods re...

CREDIT University of Warwick Abstract: •University of Warwick physicists set out to find Skyrmions, only to find near-identical object with distinctive qualities that they have named an incommensurate ...

Nanotechnology Now Home > Press > Scientists observe role of cavitation in glass fracturing Fig. 1. Observation of the cavitation-dominated crack propagation in a metallic glass. CREDIT Institute of Physics Abstract: Glassy materials play an integral role in the modern world, but inherent brittleness has long been the Achilles' heel that severely limits their usefulness. Due to the disordered amorphous structure of glassy materials, many mysteries remain. These include the fracture mechanisms of traditional glasses, such as silicate glasses, as well as the origin of the intriguing patterned f...

Home > Press > A general approach to high-efficiency perovskite solar cells Researchers from the Institute for Applied Physics (IAP) and the Center for Advancing Electronics Dresden (cfaed) at TU Dresden developed a general methodology for the reproducible fabrication of high efficiency perovskite solar cells. Their study has been published in the renowned journal Nature Communications. CREDIT Christiane Kunath Abstract: Perovskites, a class of materials first reported in the early 19th century, were "re-discovered" in 2009 as a possible candidate for power generation via their use in solar c...
