Miniaturized mobile ozone detector works in air, water and near explosive gases
Researchers in Freiburg have developed a highly-sensitive, miniaturized mobile ozone sensor which can be used not only in air, but also in water and in the vicinity of explosive gases. The Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg is developing improved chemical sensors that are not prohibitively expensive. One particularly important area of application involves the regular measurement of ozone content in air and other media. This gas is a powerful oxidizing agent and can cause a wide range of symptoms in humans, including lacrimation, irritation of the mucous membranes ... |

Ecotoxicity studies of nanomaterials urgently needed
A new study by Swiss researchers has attempted to predict nanomaterial concentrations in the environment. However, the researchers say more data on environmental toxicity are needed before we can make accurate assessments of potential environmental risks from nanomaterials. Studies based on real measurements of nanomaterials in the environment are currently almost non-existent, despite the growing use of nanomaterials in commercial products, such as cosmetics, textiles and paints. Therefore, simulations that predict how nanomaterials may be released into the environment, and in what quantities, ... |
