Theoretical approach for assembling nanoparticles uses an idea similar to separated vinaigrettes

28-Mar-2019

Materials scientists at Duke University have theorized a new "oil-and-vinegar" approach to engineering self-assembling materials of unusual architectures made out of spherical nanoparticles. The resulting structures could prove useful to applications in optics, plasmonics, electronics and ...

Simulations predict new class of carbides

28-Nov-2018

Materials scientists at Duke University and UC San Diego have discovered a new class of carbides expected to be among the hardest materials with the highest melting points in existence. Made from inexpensive metals, the new materials may soon find use in a wide range of industries from machinery ...

Photonic crystal waveguide paves the way to build futuristic light-based computers

21-Nov-2018

Engineers at Duke University have demonstrated a device that can direct photons of light around sharp corners with virtually no losses due to backscattering, a key property that will be needed if electronics are ever to be replaced with light-based devices. The result was achieved with photonic ...

A new Duke University-led study has found widespread uranium contamination in groundwater from aquifers in 16 Indian states. The main source of the uranium contamination is natural, but human factors such as groundwater-table decline and nitrate pollution may be exacerbating the problem. Several ...

Metamaterial device controls transmission and reflection of acoustic waves

11-Apr-2018

Metamaterials researchers at Duke University have demonstrated the design and construction of a thin material that can control the redirection and reflection of sound waves with almost perfect efficiency. While many theoretical approaches to engineer such a device have been proposed, they have ...
