He-like heavy ions are the simplest atomic multibody systems. They are in particular well suited to study electron-electron effects in the presence of strong Coulomb fields where QED contributions are of considerable importance. Recent progress in the spectroscopy of these ions [1] and in related theoretical investigations [2] opened new perspectives for such studies up to He-like uranium. A fu...

The antideuteron and antihelium-3 production rates at high-energy heavy ion collisions are calculated in the framework of fusion mechanism. It is supposed, that p̄,n̄,d̄,He participating in the fusion are moving in the mean field of other fireball constituents. It is demonstrated that at the ”dense gas” stage of fireball evolution, preceding the thermal freeze-out, the coalescence parameters for d̄...

The interaction between some heavy metal ions such as of Pb(II), Cd(II) and Cu(II) ions from aqueous solution adsorbed by single walled carbon nanotube (SWCNTs) and carboxylate group functionalized single walled carbon nanotube (SWCNT-COOH) surfaces were studied by atomic absorption spectroscopy. The effect of contact time, pH, initial concentration of ion, ionic strength and temperature on the...

Adsorption and desorption studies on different types of adsorbents, including natural materials such as teak tree bark powder, rice husk, natural bentonite, different algae like Ecklonia maxima, Escherichia coli, Ascophyllum nodasum, Rhizopus nigricans, Cladophora fascicularis, goethite and soils of three nuclear power plant and artificial materials such as Fe oxide-coated sand, goethite pretre...

Recent theoretical results have led to improvements in formulas for dE=dx, particularly in the regime of high projectile charge and moderate to highly relativistic velocities. In addition, integration of dE=dx leads to predictions of total range given initial energy and, reciprocally, initial energy given total range. We have compiled theoretical formulas for dE=dx from a variety of sources int...

The GSI midterm project HITRAP is a planned ion trap facility for capturing and cooling of highly charged ions (HCI) produced at GSI in the heavy-ion complex of the UNILAC-SIS accelerators and the ESR storage ring. In this facility heavy highly-charged ions up to uranium will be available as bare nuclei, hydrogen-like ions or fewelectron systems at low temperatures. The trap for receiving and s...

Heavy-ion experiments at GSI cover nuclear and atomic physics, related basic and applied research in plasma physics and material science as well as biophysics including tumor therapy with carbon ions. After low-energy sections, the heavy-ion synchrotron (SIS) provides pulsed, cooled ion beams up to 2 GeV/amu of beam intensities up to 10 ions/spill. All kind of ions from protons with Z=1 to U io...

In this study, novel polycarbonate-titanium oxide nanotubes (PC-TNT) ultrafiltration mixed matrix membranes (MMMs) were fabricated for decontamination of Cd2+ and Cu2+ metal ions from aqueous solution. The weight percent of TNTs in the polycarbonate membrane matrix was changed from 0 to 15. The synthesized neat PC membrane and PC-TNTs MMMs were characterized with respect to structural morpholog...
