Hyperspectral CMOS imager [PDF]
CCDs have been used for many years for Hyperspectral imaging missions and have been extremely successful. These include the Medium Resolution Imaging Spectrometer (MERIS) [1] on Envisat, the Compact High Resolution Imaging Spectrometer (CHRIS) on Proba and the Ozone Monitoring Instrument operating in the UV spectral region.

Mid‐infrared photothermal imaging enables multidimensional profiling of micro‐ and nanoplastics in bottled water. A total of 9.9 × 104 particles L−1 is detected, with 64% in the nanoscale regime. Spectral evolution, including peak narrowing and band shifts, reveals local chain reorganization in polyethylene terephthalate (PET), highlighting intrinsic ...

Operando real‐time current density–voltage absorption spectroscopy visualizes spatial phase evolution in mixed‐halide perovskites from device to module scale. Phase instability preferentially initiates in regions with insufficient carrier extraction, revealing electrical boundary conditions as governing factors.

An oil‐in‐water nanoemulsion transforms a boron difluoride formazanate (BDF) dye into a dual‐modal imaging‐guided theranostic agent (BDF‐NE). Its nonpolar oil core maximizes NIR‐II fluorescence while maintaining strong photoacoustic contrast to guide photothermal therapy with high photostability and 66.8% photothermal conversion efficiency, achieving ...

Silicon hot‐carrier photodetectors offer a CMOS‐compatible pathway for SWIR detection but suffer from intrinsically low quantum efficiency. Here, we introduce a quasi‐generalized antireflection coating (QARC) that universally enhances optical absorption and quantum efficiency, enabling the first CMOS‐compatible SWIR imaging with silicon hot‐carrier ...

The Future of Hyperspectral Imaging [PDF]
The Special Issue on hyperspectral imaging (HSI), entitled “The Future of Hyperspectral Imaging”, has published 12 papers. Nine papers are related to specific current research and three more are review contributions: In both cases, the request is to propose those methods or instruments so as to show the future trends of HSI.

Advancing Fruit Bioimpedance Monitoring With Sustainable, Soft, And Bio‐Based Electrodes Beyond ECG
Electrical impedance spectroscopy enables non‐destructive fruit quality monitoring, but conventional ECG and needle electrodes compromise signal stability, fruit physiology, and sustainability. This perspective highlights the transition toward soft, biocompatible, and biodegradable electrode interfaces based on natural substrates, bio‐derived ...
