A passive sampler constructed with a new type of material and used for measurement of ambient nitrogen dioxide is presented. The sampler was constructed with parts of two 50 mL conical centrifuge tubes. The procedure is ...

This study reports a functional passive sampler for monitoring gaseous elemental mercury (GEM). The material consists of gold nanoparticles (AuNP) deposited forming a film on thiol-modified glass slides. AuNP colloid was ...

In high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with ac ve detectors is useless; in these condi ons neutron measuring devices must have a passive detector. Here a passive ...
