Ultraviolet‐C light for prevention of airborne infection: A baseline analysis of web‐based public information

Photochemistry and Photobiology, EarlyView.
This study assesses whether online public information about UVC for airborne infection prevention is clear and actionable. Using the CDC's Clear Communication Index, we found that most health organization websites did not fully achieve basic communication standards.

Selective and Fast Cortisol Sensing in Human Saliva Using Graphene‐Based On‐Chip Field‐Effect Transistors

Small Science, Volume 6, Issue 10, October 2026.
Electrolyte‐gated graphene field‐effect transistors (EG‐GFETs) functionalized with anticortisol Fab fragments enable rapid, label‐free detection of cortisol in human saliva within 10 min. Sensitive operation in physiologically relevant media, together with direct validation against ELISA, demonstrates the potential of this platform for future portable ...

Simulating Regional‐Scale Aerosol Radiative Effects of Wildfire Smoke Using a High‐Resolution Coupled Meteorology‐Chemistry Model: HRRR‐Chem

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Wildfires are increasing in frequency and intensity, strongly influencing both regional air quality and the Earth's radiation budget via their aerosol emissions. Relying on an unparalleled observational data set from the 2019 NOAA/NASA FIREX‐AQ campaign, this study quantifies the direct radiative effects of two wildfires using the HRRR‐Chem ...

Correcting Airborne Laser Scanning Intensity Data

, 2011
Airborne laser scanners (ALS) produce a point cloud where each point has X, Y and Z coordinates which are determined by the combination of GNSS (Global Navigation Satellite System), IMU (Inertial Measurement Unit) and laser range finder. Additionally to coordinates points have also an intensity value recoded.
