Flow-induced errors in airborne in situ measurements of aerosols and clouds
Abstract. Aerosols and clouds affect atmospheric radiative processes and climate in many complex ways and still pose the largest uncertainty in current estimates of the Earth’s changing energy budget. Airborne in situ sensors such as the Cloud, Aerosol, and Precipitation Spectrometer (CAPS) or other optical spectrometers and optical array probes provide detailed information about the ...

When water suffers from high turbidity, Filtronics is the clear solution
Water loses its transparency and takes on a hazy appearance when it contains a large quantity of suspended solid particles. While even a moderate lack of clarity is noticeable to even casual observers, the average person would probably describe a sample of such water as “cloudy” or “murky.” The technical term – turbidity – is not widely known to laymen outside ...

Project AddRE-Mo - Case Study
AddRE-Mo project focuses on resource conservation and value retention networks for urban electromobility through additive and re-manufacturing. According to a recent study by the United Nations Organization, the number of people living in urban areas will increase from 55 % (in 2018) to an estimated 70 % in 2050. This will lead to an increase of traffic and pose a challenge for the existing ...

Your Tap Water is More Toxic than you Think
At a Glance A new study proves that while adding chlorine to water has kept water clearer of diseases such as cholera and typhoid fever, it can leave behind toxic byproducts. These byproducts may have the potential to harm an individual’s long term health. At this point we don't even know all the byproducts left in the water from the current treatment methods. Your tap water might ...
