An improved wearable, stretchable gas sensor using nanocomposites

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 …

Improving cereal storage facilities with gas sensing

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 …

Perfecting heat treatment and endothermic processing

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 role of gas sensing as a drinking water purification method

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 …

Gas Sensing Solutions investigates levels of CO2 on car journeys

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, …

GSS ultrafast CO2 sensor used to upgrade CO2Meter’s datalogger for quicker results

Carbon dioxide (CO2) is an ideal fire suppressor for many applications, because apart from actual fire damage, there is no clean-up or residue associated with a CO2 system – unlike with foaming agents or water. When a fire starts, high-pressure CO2 is released into the area it is protecting. Carbon dioxide gas …

Ultrasensitive toxic gas detector

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 nanorod arrays which can detect toxic NH3 gas. Over the years, WO3 has received considerable attention among the numerous transition metal oxides as a wide …
