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 ...

New Hybrid Nanocomposite Films for Optical Diagnostics and Optical Temperature Sensing: Synergy Among α‐Synuclein, Gold and Upconverting Nanoparticles

Small, EarlyView.
Gold and upconverting nanoparticles coated with alpha‐synuclein were exploited to produce a quasi‐monolayer hybrid film. The film was then characterized, and its behaviour as a primary optical nano‐thermometer was studied. The film was also used in a proof‐of‐concept study of image‐based optical nanothermometry exploiting a home‐built up‐conversion ...

A Bridge Transformer Network With Deep Graph Convolution for Hyperspectral Image Classification

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Transformers have been widely applied to hyperspectral image classification, leveraging their self‐attention mechanism for powerful global modelling. However, two key challenges remain as follows: excessive memory and computational costs from calculating correlations between all tokens (especially as image size or spectral bands increase) and ...
