Temperature Sensor Using Quartz Tuning Fork Resonator

Transactions of the Society of Instrument and Control Engineers, 1986
Summary This paper describes the development of a temperature sensor based on a temperature-sensitive quartz "tuning fork" resonator. The resonator was fabricated using photolithography and anisotropic etching. The optimum cut of the crystal and optimum resonator orientation on the wafer were determined - taking into account the anisotropic etching ...

Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

Advanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

Quartz Enhanced Photoacoustic Spectroscopy Based Gas Sensor with a Custom Quartz Tuning Fork

Proceedings, 2018
We have fabricated a custom quartz tuning fork (QTF) with a reduced fundamental frequency, a larger gap between the prongs and the best quality factor in air at atmospheric conditions ever reported.

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

Advanced Functional Materials, EarlyView.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create
