A semiconducting material with a puckered pentagonal atomic structure, characterized by Oak Ridge National Laboratory, could rival graphene and black phosphorus as a viable option for nanoscale electronics. The ORNL-led team studied a novel two-dimensional, or atomic-thin, layered...
Oak Ridge National Laboratory’s Bo Shen works with a prototype window air conditioning unit that cools using propane, which lowers costs, increases efficiency and benefits the environment.

Cooling homes and small office spaces could become less costly and more efficient with new early stage technology developed by Oak Ridge National Laboratory. Researchers designed a window air conditioning unit that uses propane as the refrigerant, cooling the air with 17 percent h...

An ORNL-led team formed seamless interfaces between graphene ribbons with different widths, creating a staircase configuration. This configuration has seamless electrical contacts, making the material viable as a building block for next-generation electro
A new approach developed by Oak Ridge National Laboratory creates seamless electrical contacts between precisely controlled nanoribbons of graphene, making the material viable as a building block for next-generation electronic devices. In a recent study, an ORNL-led team grew the ...
