Speeding through nanowire

Nanowires under tension create the basis for ultrafast transistors

09-Feb-2022 - Smaller chips, faster computers, less energy consumption. Novel concepts based on semiconductor nanowires are expected to make transistors in microelectronic circuits better and more efficient. Electron mobility plays a key role in this: The faster electrons can accelerate in these tiny wires, ...

Lightning bolt underwater

01-Jul-2019 - A plasma tears through the water within a few nanoseconds. It may possibly regenerate catalytic surfaces at the push of a button. Electrochemical cells help recycle CO2. However, the catalytic surfaces get worn down in the process. Researchers at the Collaborative Research Centre 1316 “Transient ...

Carrying and releasing nanoscale cargo with 'nanowrappers'

Nanocubes for biomedicine, catalysis and beyond

08-Jan-2019 - This holiday season, scientists at the Center for Functional Nanomaterials (CFN)--a U.S. Department of Energy Office of Science User Facility at Brookhaven National Laboratory--have wrapped a box of a different kind. Using a one-step chemical synthesis method, they engineered hollow metallic ...

Multimodal imaging shows strain can drive chemistry in a photovoltaic material

27-Sep-2018 - A unique combination of imaging tools and atomic-level simulations has allowed a team led by the Department of Energy's Oak Ridge National Laboratory to solve a longstanding debate about the properties of a promising material that can harvest energy from light. The researchers used multimodal ...

A deep look into a single molecule

10-Feb-2016 - A German research group has demonstrated the first implementation of a non-destructive state detection technique for molecular ions. Piet Schmidt and his colleagues from the QUEST-Institute at the Physikalisch-Technische Bundesanstalt (PTB) observed changes in the rotational state of a trapped ...
