Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
Developing a standoff coherent Raman spectrometer
A novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions has been constructed by Yao Fu and colleagues. The device can remotely probe chemical species in real time with high temporal resolution while monitoring.....»»
Why can"t we replace sniffer dogs with electronic noses?
Compared to other senses, our sense of smell is often overlooked. Our noses can alert us to risks such as rotten food, gas leaks and burning toast. But for advanced tasks such as detecting bombs or contraband, or diseases such as cancer, we often rel.....»»
