Our recent work with cyclic and acyclic polyether self-assembled monolayers (SAMs) on gold is presented. A series of dithia-crown-tetrathiafulvalene derivatives with one or two disulfide groups has been prepared, and their SAMs on gold have been characterized by electrochemistry and by reflection-absorption infrared spectroscopy. These SAMs are extremely stable on repeated electrochemical poten...

It was shown scientifically substantiated the use of lesser duckweed (Lemna minor L.) as a test object for environmental monitoring purposes when contaminated with copper (II), iron lead and zinc cations. The influence metal cations in concentration range from 0.1 to 10.0 mg/l on specific growth rate dynamics changes total area leaf blades (fronds) freshwater plants has been studied. that Cu2+ ...
