The 2.6nm-long single molecule wire has quasi-metallic properties and shows an unusual increase of conductance as the wire length increases

12-Jul-2022

As our devices get smaller and smaller, the use of molecules as the main components in electronic circuitry is becoming ever more critical. Over the past 10 years, researchers have been trying to use single molecules as conducting wires because of their small scale, distinct electronic ...

New 3D imaging tool reveals engineered and self-assembled nanoparticle lattices with highest resolution yet

21-Apr-2022

From designing new biomaterials to novel photonic devices, new materials built through a process called bottom-up nanofabrication, or self-assembly, are opening up pathways to new technologies with properties tuned at the nanoscale. However, to fully unlock the potential of these new materials, ...

Discovery could optimize electrolyte design for stable lithium metal batteries, enabling lightweight, low-cost, long-lasting energy storage

09-Nov-2020

Electric vehicles (EVs) hold great promise for our energy-efficient, sustainable future but among their limitations is the lack of a long-lasting, high energy density battery that reduces the need to fuel up on long-haul trips. The same is true for houses during blackouts and power grid ...

Multi-messenger approach allows to probe electronic and magnetic materials at ultra-small length scales

07-Jan-2020

Researchers at Columbia University and University of California, San Diego, have introduced a novel "multi-messenger" approach to quantum physics that signifies a technological leap in how scientists can explore quantum materials. "We have brought a technique from the inter-galactic scale down to ...

Most synthetic materials, including those in battery electrodes, polymer membranes, and catalysts, degrade over time because they don't have internal repair mechanisms. If you could distribute autonomous microrobots within these materials, then you could use the microrobots to continuously make ...
