Microscopic Acid‐Induced Degradation and Elemental Release From Thermoformed and 3D‐Printed Orthodontic Aligners in a Simulated Gastric Environment

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 10, October 2025.
ABSTRACT Clear aligners have revolutionized orthodontic treatment, yet concerns are rising about microplastics (MPs) and nanoplastics (NPs) released from these devices through mechanical wear and chemical degradation. Once ingested, these particles may undergo structural and chemical transformations in the gastrointestinal tract, particularly under ...

Monte Carlo method in optical atomic force microscopy

Journal of Measurement Science and Instrumentation, 2021
Scanning probe microscopy（SPM） is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. Atomic force microscopy is one of the SPM family which is considered as a very versatile tool for surface imaging and ...

Time‐Resolved Cathodoluminescence Spectroscopy of Oxygen‐Related Defects in AlN Layers

physica status solidi (b), Volume 262, Issue 10, October 2025.
High‐temperature annealing significantly improves the crystal quality of sputter‐deposited AlN templates, but at the same time introduces oxygen‐related defects. Their origin is investigated using time‐resolved cathodoluminescence spectroscopy. Furthermore, these defects impact the deep‐UV transparency of the AlN templates.

Multiscale Fabrication and Characterization of a NEMS Force Sensor

Advanced Materials Technologies, Volume 10, Issue 4, February 19, 2025.
Fabricated silicon nanowires integrated with MEMS shuttle on a silicon‐on‐insulator wafer using novel fabrication technology enable the device to detect subtle multi‐axis forces. Gage factor tests show static manipulation response, while dynamic analysis indicates robustness and high resonant frequency.

Quantum criticality in the coupled two-leg spin ladder Ba2CuTeO6

, 2017
We report on zero-field muon spin rotation, electron spin resonance and polarized Raman scattering measurements of the coupled quantum spin ladder Ba2CuTeO6. Zero-field muon spin rotation and electron spin resonance probes disclose a successive crossover

Surface‐Enhanced Raman Scattering and Photothermal Effects on Optoplasmonic Nanofibers

Advanced Optical Materials, Volume 12, Issue 34, December 3, 2024.
Plasmonic nanofibers made of pulled glass fibers decorated with metallic nanoparticles exhibit unique optical properties owing to the interactions between the incident light with both the optical modes of the nanofiber and the localized surface plasmon resonance of the nanoparticles.

Graphene-on-Sapphire and Graphene-on-Glass: Raman Spectroscopy Study

, 2007
The room-temperature Raman signatures from graphene layers on sapphire and glass substrates were compared with those from graphene on GaAs substrate and on the standard Si/SiO2 substrate, which served as a reference.
