Transparent electrical conductors are useful, e.g., in solar cells, sensors, displays, or smart windows. Indium tin oxide (ITO) thin films are commonly used for such applications, but the material is brittle and can crack under mechanical stress. Thin films made from silver nanowires are a possible alternative as a flexible, transparent conductor. However, their conductivity is reduced by polyvinylpyrrolidone (PVP) ligands that are used during nanowire synthesis and remain on the surface.
Chosen from a pool of 343 nominated promising scientific researchers aged 42 years and younger from America’s top academic and research institutions, Duan is one of ten Physical Sciences & Engineering finalists. The finalists were selected based on their extraordinary accomplishments and their promise for the future.
Titled “Van der Waals Integration Before and Beyond Two-dimensional Materials”, the article was published in the March 20, 2019 issue of the journal.
As a UCLA professor of chemistry and biochemistry, Prof. Duan is also an Associate Editor for the journalNano Research. In 2018, Duan was named one of the most influential scientific researchers by Clarivate Analytics.
A new mechanically strong, double-pane ceramic aerogel made from hexagonal boron nitride that is resistant to high temperatures could be used in aerospace and industrial applications. The material, which boasts both a negative Poisson’s ratio and a negative thermal expansion coefficient, is very different to typical ceramic aerogels that are brittle and structurally degrade under thermal shocks.
Six faculty members from UCLA have been selected as 2018 fellows of the American Association for the Advancement of Science. They are to be honored by the association for their scientifically or socially distinguished efforts to advance science or its applications.
