According to a report by Scientific American on September 22, when maple trees begin to release their “winged” seeds, these seeds spiral gently down from the branches to the ground. Inspired by the aerodynamic characteristics of these helicopter-like samaras and other gliding tree species, engineers claim to have created the smallest wind-powered flying machines ever … Read more
Nitrogen dioxide (NO₂) is a major nitrogen oxide (NOx) pollutant produced by the combustion of fossil fuels, posing significant threats to the ecosystem and human health, necessitating effective detection methods to monitor NO₂. Current NO₂ detection technologies have limitations in stability and selectivity. According to reports from Maims Consulting, a research team led by Professor … Read more
Stability in High Humidity Environments: Due to the high humidity in mushroom cultivation environments, the sensor needs to operate stably even in high humidity conditions, avoiding measurement distortion caused by condensation in the gas chamber. Measurement Range and Accuracy: The measurement range should cover 0-10000 PPM, with an error range controlled within ±100 PPM to … Read more

Small unmanned aerial vehicles (UAVs) have become very popular in aerial photography, while radar imaging can provide more supplementary information. Therefore, installing radar on UAVs can be applied in fields such as science, agriculture, and environmental monitoring. However, UAV SAR systems are often too heavy and require support from large UAVs. This article introduces a … Read more
