The use of the pesticides – DDT (1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane) and lindane (gamma-hexachlorocyclohexane) – and of PCBs (polychlorinated biphenyls) has been limited or forbidden for several decades. Nevertheless, due to their persistence and bioaccumulative potentials they are still ubiquitous in the environment. Therefore, the main objective of this study was to determine analytical...
The concept of ultrafast optical switches based on the nonlinear response of loaded plasmonic nanoantennas is proposed and explored. The plasmonic nanoswitch shows a transition from a capacitive to a conductive coupling regimes in the gap between two closely spaced metal nanorods. A photoconductive semiconductor in the gap is used to generate a free-carrier plasma which short circuits the antenna...
The main objective of this study was to generate a fast analytical method to determine the five phthalates benzylbutylphthalate (BBP), dibutylphthalate (DBP), di-(2-ethylhexyl)-phthalate (DEHP), di-isodecylphthalate (DIDP), and di-isononylphthalate (DINP) in house dust. To achieve this liquid chromatography electrospray tandem mass spectrometry (LC–ESI–MS/MS) was used for measurement. The risk of...
