The adsorption of a nonionic surfactant, polyoxyethylene-4-nonylphenyl ether, on porous and non-porous polymer substrates is studied. The results obtained are discussed and compared with previously published data on the adsorption of an anionic surfactant on same substrates. It is concluded that the behavior of anionic and nonionic surfactants in negatively charged pores of approximately 100 nm in radius differs strongly due to electrostatic co-ion exclusion, which plays a significant role only in the case of ionic species.
13.04.2017 - FLNR Scientific Seminar "ACCULINNA-2 first radioactive ion beams and the first experiments program", 15-00 Flerov Lab Conference Hall.
In March 2017 ACCULINNA-2 basic setup for radioactive ion beam production was put into operation at U400M heavy ion accelerator.
The results of the test experiments agree very well with the design parameters.
The principal stages of U400M+ACCULINNA-2 accelerator complex development up to the end of JINR current seven years plan and its vistas for 2023-2030 years will be presented in the reports and brought up for the discussion.
