Monitoring the air particulate concentration both outdoors and indoors is becoming a more relevant issue in the past few decades. An innovative, fully automatic, monitoring system called CleAir is presented. Such a system wants to go beyond the traditional technique (gravimetric analysis), allowing for a double monitoring approach: the traditional gravimetric analysis as well as the optical spe...

We propose new isoreticular metal-organic framework (IRMOF) materials to increase the hydrogen storage capacity at room temperature. Based on the potential-energy surface of hydrogen molecules on IRMOF linkers and the interaction energy between hydrogen molecules, we estimate the saturation value of hydrogen sorption capacity at room temperature. We discuss design criteria and propose new IRMOF...

Frequency-domain expressions are found for gradiometer and satellite-to-satellite tracking measurements of a point source on the surface Earth. The maximum signal-to-noise ratio as function noise in measurement apparatus is computed, from that minimum detectable mass inferred. A magnitude M3=100Gt gives 3 when GOCE-like passes directly over mass. On mission GRACE-FO M3=1.3Gt microwave instrumen...
