In an article published in Remote Sensing, researchers used geostatistical analysis, low-density airborne laser scanning (ALS) metrics, and forest inventory data to estimate old-growth indices (OGIs) as indicators of old-growth forest conditions.
In an article published in Biosensors, researchers have constructed a disposable, flexible, simple and cost-effective colorimetric film sensor to rapidly detect gaseous ammonia.
A ZnO-coated optical fiber sensor for detecting a volatile organic compound biomarker for diabetes has been recently demonstrated in a study published in Sensors. The researchers used a coreless silica fiber (CSF) coupled with single-mode fiber (SMF) at both ends to synthesize the SMF-CSF-SMF structure.
