Chin-Hao Chang’s research Scratch-resistant sapphire nanostructures with anti-glare, anti-fogging, and anti-dust properties published in Materials Horizons journal. This work demonstrates a novel transparent window made of sapphire nanostructures with anti-glare, anti-fogging, self-cleaning, and, most importantly, scratch-resistant properties. The new key concept is that by engineering the material composition and geometry of nanostructures, their material properties can be tailored in multiple physical domains. This work also provides the key insight that nanostructures can be as durable as smooth ceramic and scratch-resistant metal surfaces.
The SEM shows the sapphire nanostructures at peak nanoindentation load and the onset of fracture of the structures, but the crack is localized and does not propagate into the substrate.
An academic and industry research team led by Michael Cullinan is Holographic Metasurface Nano‑Lithography (HMNL), a 3D‑printing method that can create complex chip packages in a single step. Their work, supported by a $14.5 million DARPA award and a team of academic and industry partners, could dramatically speed up semiconductor manufacturing while reducing waste.
Linran Fan’s research focuses on nonlinear interactions between optical photons, superconducting circuits, electron spins, and acoustic waves at the quantum level in a hybrid system of novel integrated devices and materials. Target applications include photonic information processing, communication, and precision measurement enhanced by quantum information science.
