High‐Resolution Multispectral Photovoltaic Imagers from Visible to Short‐Wave Infrared

Advanced Science, Volume 13, Issue 18, 27 March 2026.
We demonstrate a monolithic quad‐spectral imager that seamlessly integrates visible and short‐wave infrared detection on a single chip. Through direct photopatterning of an all‐polymer bulk heterojunction and colloidal quantum dots, the device achieves high‐resolution (640 × 512) imaging across 350–2400 nm, enabling multispectral capture for ...

Sensitive and Precise Detection of Volatile Organic Compounds and Carbon Dioxide for Evaluating Photo‐Degradation Processes of Indoor Air Pollutants

Chemistry–Methods, Volume 6, Issue 3, March 2026.
Highly sensitive analytical methods facilitate the detection of volatile organic compounds (VOCs) and their reaction products at ppm–ppb levels. In the developed combined reactor‐analytical device setup, acetone was detected down to 1 ppm when photodegrading it over a TiO2 photocatalyst.

Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

The Chemical Record, Volume 26, Issue 3, March 2026.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...

Evaluation of the Webler-Brown model for estimating tetrachloroethylene exposure from vinyl-lined asbestos-cement pipes

Environmental Health, 2008
Background From May 1968 through March 1980, vinyl-lined asbestos-cement (VL/AC) water distribution pipes were installed in New England to avoid taste and odor problems associated with asbestos-cement pipes.
