Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

Small, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

Small, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Thermal Conductive Network Construction and Enhanced Thermal Conductivity in Mica Tape Composites for Large Generators by Pre‐Placed h‐BN@PDA‐Modified Mica Paper

High Voltage, EarlyView.
ABSTRACT The lower thermal conductivity (TC) of mica tape hinders the evolution of large generators towards higher voltage and capacity. To enhance the TC of the mica tape, with the help of the three‐dimensional (3D) multi‐layer framework of the mica paper, a 3D polydopamine‐coated boron nitride (h‐BN@PDA) TC network was constructed by pre‐placing h‐BN@
