AutoSAFT: Autofocusing for extended depth of imaging in scanning acoustic microscopy
Journal of Microscopy, EarlyView.Abstract In the scanning acoustic microscopy (SAM) imaging, it is essential to address the diminished lateral resolution in the out‐of‐focus region, as image quality correlates with the ultrasound propagation distance either above or below the focal plane.

Detecting charge transfer at defects in 2D materials with electron ptychography
Journal of Microscopy, EarlyView.Abstract Electronic charge transfer at the atomic scale can reveal fundamental information about chemical bonding, but is far more challenging to directly image than the atomic structure. The charge density is dominated by the atomic nuclei, with bonding causing only a small perturbation. Thus detecting any change due to bonding requires a higher level

Spectrophotometric analyses on electronic structures of glide dislocation cores in ZnS
Journal of the American Ceramic Society, Volume 108, Issue 6, June 2025.Abstract It has been reported that dislocations in ZnS can trap photoexcited carriers and then undergo core reconstruction. However, electronic states of the trapped carriers at the reconstructed dislocations were not detected experimentally.

Advanced Functional Materials, Volume 35, Issue 14, April 3, 2025.This work integrates nano‐sized cobalt control gates into a fully‐depleted silicon‐on‐insulator (FDSOI) nanowire architecture, combining electrical and ferromagnetic properties for scalable electron spin qubits. The design enables quantum dot formation at cryogenic temperatures and localized electric dipole spin resonance (EDSR).

Advanced Materials, Volume 37, Issue 14, April 9, 2025.From oil refining to high refractive index photopolymers for bulk plastic optics. The synthesis of a new photopolymer resin derived from inexpensive sulfur petrochemicals is reported affording a high‐quality optical glass that is amenable to a wide range of photopolymerization‐based fabricated methods, including 3D Printing, for precision plastic ...

Portable Filter-Free Lens-Free Incoherent Digital Holography System
PhotonicsA portable incoherent digital holography system without a polarization filter or a refractive lens was developed. Phase-shifted self-interference incoherent holograms of light diffracted from an object were generated without attenuation due to a ...
