Sensirion has launched its new formaldehyde sensor module, the SFA30. The SFA30’s innovative electrochemical cell design, dedicated electronics including an onboard Sensirion humidity and temperature sensor, and advanced algorithms, enables highly reliable and selective formaldehyde detection at very low concentrations. This new sensor thus targets the appliance market focusing on …

An optical sensor manufactured by ABB was deployed with the successful launch of satellite Hugo from GHGSat, the emerging leader in greenhouse gas sensing services in space. The ABB supplied optical sensor can map methane emissions from space at a resolution that is 100 times higher than any other sensors. …

Covid-19 is a highly contagious disease and to mitigate the spread of the virus especially indoors, the common refrain is to make sure the space is well ventilated with fresh air. But what exactly is fresh air? Fresh air is typically defined as cool, unpolluted air in natural surroundings. But …

Stunning methods are used to cause unconsciousness in animals prior to slaughter. Ideally, stunning will leave an animal insensible to pain and distress during the slaughtering process, while causing minimal distress in itself. Of the available stunning methods, percussive or electrical methods are the most widely used but gas stunning …

A stretchable, wearable gas sensor for environmental sensing has been developed and tested by researchers at Penn State, Northeastern University and five universities in China. The sensor combines a newly developed laser-induced graphene foam material with a unique form of molybdenum disulfide and reduced-graphene oxide nanocomposites. The researchers were interested …

Storage of cereal crops and other foodstuffs is an essential part of ensuring a sustainable and robust food supply. Cereal crops are typically harvested between mid-July to mid-September but with careful storage can be kept for periods longer than a year. Successful storage of cereals involves the balance of a …

Supermarkets all over Australia and New Zealand are benefiting from advanced carbon dioxide monitors as new natural refrigeration systems are installed in the fight against climate change. The Woolworths Group employs over 205,000 staff and serves 900 million customers each year. As a large and diverse organisation, Woolworths knows that …

For iron and steel, one of the most common approaches for hardening these relatively soft materials is to perform heat treatment under endothermic atmospheres. There are many methods for heat-treating metal alloys, some of which include case-hardening or surface hardening and annealing, but the general purpose of the treatment is …

The processing of clean and safe drinking water and drinking water purification methods are an international issue. Estimates suggest that, if no further improvements are made to the availability of safe water sources, over 135 million people will die from potentially preventable diseases by 2020. Even within the UK, water …

Ever wondered why long car journeys make you feel tired and sleepy? Is it the boredom of endless, never changing motorways or perhaps something else? Carbon Dioxide sensor specialists, Gas Sensing Solutions, wondered if it could be a build-up of CO2 gas because, at levels of 1,000 ppm and above, …
