Recent advances in organic broad‐spectrum photodetection materials and devices

open access: yesInfoMat, EarlyView.
Graphical Abstract This review systematically outlines the evolution of organic photodetectors from fullerene‐based to advanced non‐fullerene acceptors, highlighting how molecular engineering (e.g., D–A, quinoidal, and A‐D‐A′‐D‐A architectures) extends spectral response into the short‐wave infrared region.

Bioanalytical TERS and Advanced Data Processing Methods

open access: yesJournal of Raman Spectroscopy, EarlyView.
Tip‐enhanced Raman spectroscopy delivers label‐free, subnanometer vibrational imaging of biological systems. Recent advances in instrumentation, data analysis, and ambient/liquid operation enable surface‐selective mapping of molecular heterogeneity in proteins, nucleic acids, membranes, and viruses, positioning TERS as a powerful platform for nanoscale

Compact Hyperspectrals

open access: yes, 2011
Numerous Hyperspectral Imagers have been launched or are being built for resource management, monitoring anthropogenic effects on the troposphere gases, and for defense applications. Payloads such as Hyperion, EnMAP, HyspIRI, and SCHYAMACHY are instruments with mass in excess of 100 Kg.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

open access: yesJournal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Red, green, blue color indices as proxy for Symbiodiniaceae cell density and chlorophyll content during coral bleaching

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Coral bleaching, the breakdown of the symbiosis between the coral host and endosymbiotic microalgae, is the main cause of widespread coral reef degradation. Current visual assessment methods for coral health, including color reference cards, are constrained by subjective human color perception and limited resolution.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Two-Orientations Finite Markov Real-Time Local Anomaly Detection via Pixel-by-Pixel Processing for Hyperspectral Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Real-time local anomaly detection needs to be performed simultaneously with hyperspectral image acquisition. However, the discussion on the scope of using existing data, mainly focuses on line-by-line data acquisition methods and does not address pixel ...
