Ultrasensitive toxic gas detector

In a paper published in Nano, researchers from the School of Microelectronics in Tianjin University have discovered a two-step sputtering and subsequent annealing treatment method to prepare vertically aligned WO3-CuO core-shell ...

SmokeBot – a robot serving rescue units

SmokeBot is a robot developed to assist fire services and rescue units in deployments under critical conditions. It collects data about accident and disasters situations with extremely limited visibility, effectively improving ...

Sensor detects whiff of bad breath

Ever wish you could do a quick "breath check" before an important meeting or a big date? Now researchers, reporting in ACS' journal Analytical Chemistry, have developed a sensor that detects tiny amounts of hydrogen sulfide ...

Lining MOF pockets to detect noxious gases

A porous material with tailor-made pockets stitched into its structure is a promising material for sensing noxious gases. A thin film of the material, coated onto an electrode, formed an electronic sensor that could detect ...

Portable device to sniff out trapped humans

The first step after buildings collapse from an earthquake, bombing or other disaster is to rescue people who could be trapped in the rubble. But finding entrapped humans among the ruins can be challenging. Scientists now ...

MXene material could improve sensors that sniff

Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's ...

Researchers greenlight gas detection at room temperature

Russian researchers have developed a mechanism for detecting molecular hydrogen using green light to illuminate a nanocrystalline composite sensor based on zinc and indium oxides. This enables a gas sensor operating at room ...
