Novel SERS sensor helps to detect aldehyde gases

Prof. Huang Qing's group from the Hefei Institutes of Physical Science (HFIPS) developed a surface-enhanced Raman spectroscopy (SERS) gas sensor to detect aldehyde with high sensitivity and selectivity, which provided a new ...

Mind the nanogap: Fast and sensitive oxygen gas sensors

Oxygen (O2) is an essential gas not only for us and most other lifeforms, but also for many industrial processes, biomedicine, and environmental monitoring applications. Given the importance of O2 and other gases, many researchers ...

Wearable sensors that detect gas leaks

Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that can quickly detect ...

Researchers develop ultra-sensitive flow microsensors

A team of scientists at the University of Massachusetts Amherst have developed the thinnest and most sensitive flow sensor, which could have significant implications for medical research and applications, according to new ...

New sensor paves way to low-cost sensitive methane measurements

Researchers have developed a new sensor that could allow practical and low-cost detection of low concentrations of methane gas. Measuring methane emissions and leaks is important to a variety of industries because the gas ...

Measuring ozone chemistry in an occupied residence

An international team of researchers has taken a look at the amount of ozone in an occupied residence in order to measure both ozone and volatile organic compounds (VOCs) associated with chemical reactions with ozone. In ...

Taking greenhouse gas analysis on the road, er, rails

Research-grade air quality sensors are costly—around $40,000. For cities trying to monitor their greenhouse gas emissions, the cost may limit the number of sensors they can install and the data they can collect.
