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 ...

Short-Wavelength Infrared Imaging of Infected and Affected Dentin

Diagnostics
Stains produced by bacteria or those found in blood and food byproducts accumulate in highly porous caries lesions. They can interfere with accurate diagnosis and the selective removal of carious tissue during cavity preparations.

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 ...

Retrieval of rice biophysical parameters from Sentinel‑2 using parsimonious multi‑output machine learning

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Rice (Oryza sativa L.) crop monitoring in Africa requires efficient retrieval of biophysical parameters such as leaf area index (LAI) and leaf chlorophyll content (LCC), which are essential for crop stress detection and nutrient management.

Impact of Urban Environmental Indices on Surface Temperature in Dhaka: A Policy‐Oriented Perspective

Climate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
ABSTRACT Dhaka's rapid urban expansion has intensified surface heating and degraded environmental quality. This study analyzes environmental indices from 2015 to 2025, revealing a strong positive relationship between built‐up growth and land surface temperature, and negative associations with vegetation and water presence.

Vegetation and Topographic Controls on Post‐Fire Snowpack: Evidence From the 2021 Caldor Fire

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT The increase in wildland fires in recent decades due to long‐term fire suppression policies and increasingly favourable climate factors has also increased the elevation range of wildland fires. In the mountainous western United States, this has led to an increasing influence of fire on landscape‐level vegetation patterns in snow‐dominated ...
