In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Cellulose as a Platform for Biodegradable Metasurfaces: THz Characterization and Fabrication
The demand for sustainable THz technologies has motivated the development of biodegradable, flexible devices based on ethyl cellulose. Metal‐backed EC metasurfaces were analytically designed and fabricated to achieve near‐perfect THz absorption. Reflection‐mode THz spectroscopy confirmed resonant absorption at 0.576 and 0.411 THz, demonstrating the ...

Ultrafast Dynamics of Spin Current and Electron Temperature in Spintronic Terahertz Emitters
This work quantifies optical‐pump‐induced THz transmission variations to reveal electron and lattice temperature dynamics and presents time‐resolved THz spectral maps for sub‐picosecond analysis. A 63 ± 8 fs time lag between THz emission and laser excitation is identified, serving as an intrinsic parameter limiting the upper frequency of spintronic THz

Overview of MSG‐assisted GABA enrichment and associated changes in amino acid, fatty acid, and volatile metabolite profiles in germinated black highland barley. ABSTRACT γ‐Aminobutyric acid (GABA) is a functional amino acid with multiple health benefits; however, the mechanism of its enrichment in black highland barley, particularly through precursor ...

Hexagonal Hollow‐Core Photonic Crystal Fiber for High‐Sensitivity Terahertz Glucose Detection
A novel hexagonal hollow‐core photonic crystal fiber (HPhCF) operating at 2.2 THz is proposed for rapid, non‐invasive detection of urinary glucose. The Zeonex‐based hollow‐core architecture enhances light‐analyte interaction, enabling 96.90% relative sensitivity while maintaining ultra‐low confinement loss and low effective material loss.

This study develops a tyrosinase‐activated cyclic peptide self‐assembly system to combat drug‐resistant melanoma. Cyclization of tyrosine/lysine‐rich peptides via ortho‐phthalaldehyde enables tyrosinase‐triggered quinone formation and nanostructure assembly, disrupting melanoma cell cytoskeletons by blocking actin polymerization and inducing apoptosis.
