Split-ring resonator with interdigital Split electrodes as detector for liquid and ion chromatography

Sensing and Bio-Sensing Research
The analysis of food and drugs as well as the monitoring of chemical processes and bioreactors by high-performance liquid chromatography and ion chromatography requires universal, cost-effective, and sensitive detectors.

Hierarchical Cellulose/MXene Aerogel Films with Coral‐Like Polyaniline Skin for Absorption‐Led Broadband EMI Shielding

Advanced Functional Materials, EarlyView.
A regenerated cellulose/MXene aerogel film is engineered with a surface‐confined, coral‐like polyaniline skin to intensify interfacial polarization while a porous, percolated conductive core is retained. By molten salt hydrate processing and interfacially confined oxidative polymerization, PANI growth is localized at the outer surface and internal ...

Furan‐Substituted Phosphine‐Oxide as an Efficient Interfacial Modifier for Wide‐Bandgap Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.

Near-Field Microwave Microscopy of Materials Properties

, 2000
Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad ...

Observation of Two‐Photon Resonant Raman Scattering via the Biexciton Level in Two‐Dimensional Halide Perovskite (C6H5C2H4NH3)2PbI4

Advanced Functional Materials, EarlyView.
Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification

Advanced Healthcare Materials, EarlyView.
We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.
