One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

open access: yesAdvanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Chiral Microneedle Arrays With Terahertz Chiroptical Activity With Chiral‐Plasmon‐Chiral‐Phonon Resonance

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Microneedle arrays (MNAs) is a rapidly emerging technology with broad biomedical applications in drug delivery and biosensing. With sub‐millimeter dimensions and periodicity, MNAs possess geometries nearly ideal for biomedical devices operating within the terahertz (THz) spectral window.

Trapping and Detrapping Mechanisms of Deuterium in SiC Studied by XPS and TDS Techniques

open access: yesMATERIALS TRANSACTIONS, 2005
The elucidation of the trapping and detrapping mechanisms of hydrogen isotopes in SiC is one of the most critical issues for future fusion reactors if SiC is used as the first wall and structure material. In this study. 1keV deuterium (D 2 + ) ions were implanted into SiC and the chemical states of C and Si were evaluated by X-ray photoelectron ...

Improved acquisition time via adaptive sampling for THz-TDS

open access: yes, 2014
We propose an adaptive sampling method to reduce the average sampling time for THz-TDS. The sampling time improves up to threefold as the new approach takes only 20% to 30% of samples compared to conventional sampling acquisition, depending on the ...

Internal triaxial strain imaging of visibly opaque black rubbers with terahertz polarization spectroscopy

open access: yesAPL Photonics, 2017
We demonstrate the nondestructive imaging of internal triaxial strain in visibly opaque black rubbers by employing the polarization-sensitive terahertz time-domain spectroscopy (PS THz-TDS) technique.

Hydroponic Nutrient Control System Based on Internet of Things

open access: yesCommIT Journal, 2019
The human population significantly increases in crowded urban areas. It causes a reduction of available farming land. Therefore, a landless planting method is needed to supply the food for society.

Machine Learning Methods for Spaceborne GNSS-R Sea Surface Height Measurement From TDS-1

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Sea surface height (SSH) retrieval based on spaceborne Global Navigation Satellite System Reflectometry (GNSS-R) usually uses the GNSS-R geometric principle and delay-Doppler map (DDM).

Lattice Considerations for the Use of an X-Band Transverse Deflecting Structure (TDS) at SINBAD

open access: yes, 2017
An X-band TDS is a well-known device for the characterization of the longitudinal properties of an electron bunch in a linear accelerator. It is planned that a novel X-band TDS with variable polarization* will be installed within the next few years at ...

Targeted Modulation of d‐Band Center in MoS2 Interlayer With n‐Type Co/Fe Dopants Accelerating Sulfur Reaction Kinetics in Lithium‐Sulfur Batteries

open access: yesAdvanced Materials, Volume 38, Issue 36, 26 June 2026.
A targeted modulation of the MoS2 electronic structure is achieved via substitutional n‐type Co/Fe co‐doping. This strategy triggers S‐mediated d‐p hybridization, optimizing the binding affinity with polysulfides to establish a volcano‐shaped relationship between the d‐band center and catalytic activity.
