Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

New Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).

Reconstructing fresh green leaf spectra in the SWIR-2 region (2001–2500 nm) collected in a humid environment by referring to publicly available green leaf spectral databases

International Journal of Applied Earth Observations and Geoinformation
Leaf spectra (reflectance and transmittance) are commonly measured using a portable spectroradiometer and an integrating sphere or contact probe with an artificial light source.

Satellite‐Based Assessment of Methane Emissions From the Darvaza Gas Crater

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Methane is a potent greenhouse gas, and the Darvaza crater in Turkmenistan is a rare, persistent emitter. There are uncertainties regarding its formation date (either 1963 or 1971), fire ignition, and the fire's influence on methane release. Using historical Landsat imagery, we reconstruct the fire history, identifying that combustion began ...

A Colloidal Quantum Dot Thermistor and Bolometer

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Short‐Wavelength Infrared Imaging with Organic Photodetectors Based on Non‐Fullerene Acceptors with Detection above 1200 nm

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
Solution‐processed organic photodetectors (OPDs) based on two novel low band gap non‐fullerene acceptors BZIC‐2F and BZIC‐2Cl, when blended with common polymer donor P3HT, extend detection range beyond 1200 nm with superior performance, rivaling costly inorganic sensors and past literature.

Decoupling the Impact of Deep‐Trap and Band‐Tail States on PbS Quantum Dot Photodetectors via Alkylamine Engineering

Advanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
Band‐tail and deep trap states are effectively disentangled through the use of selective alkylamine additives. PA‐driven 2D ordering narrows band tails, while HA enhances halide passivation and Pb coordination to suppress deep traps. A comparative study of their CQD short‐wave infrared (SWIR) photodetectors further reveals whether band‐tail states or ...

Active Targeting in the SWIR and Extended SWIR

Passive imaging systems provide important targeting information for military platforms, but can fail in conditions of reduced illumination (including nighttime operation) and in degraded visual environments such as smoke, haze, and fog.

Spectrally Encoded Proximity‐Field Nanopatterning

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Spectrally encoded proximity‐field nanopatterning (SEPN) enables continuous control of the out‐of‐plane periodicity of 3D photonic crystals by tuning the exposure wavelength while maintaining a fixed in‐plane period. This decouples near‐infrared reflectance from visible iridescence and allows fabrication of integrated multipattern devices with ...
