An in-situ assessment of low-density polyethylene and silicone rubber passive samplers using methods with and without performance reference compounds in the context of investigation of polychlorinated biphenyl sources in rivers
Luiz Felippe De Alencastro, Nicolas Estoppey, Adrien Schopfer, Camille Fong
This study firstly aims to assess the field performances of low density polyethylene (LDPE) and silicone rubber (SR) samplers for the monitoring of polychlorinated biphenyls (PCBs) in water regarding the uptake, the sam- pling rate (RS) estimated by using ...
Elsevier Science Bv2016Precision glass molding of high-resolution diffractive optical elements
Hans Peter Herzig, Toralf Scharf, Karin Prater
The demand of high resolution diffractive optical elements (DOE) is growing. Smaller critical dimensions allow higher deflection angles and can fulfill more demanding requirements, which can only be met by using electron-beam lithography. Replication techn ...
