Simulation of iron oxide (magnetite and maghemite) and aluminosilicate (sillimanite and cyanite) deposits formed on the surface of spent ionexchange resins in the process of decontamination of liquid radioactive waste contaminated by cesium and cobalt radionuclides has been performed. A method of deep deactivation of spent ion-exchange resins contaminated by aluminosilicate and iron oxide deposits using alkaline and acidic solutions containing Zn-EDTA complexes has been suggested. The method of two-stage concentrating of cesium radionuclides using selective sorption materials (resorcinol-formaldehyde resin and Thermoxid-35 ferrocyanide sorbent) has been improved. The method advantage consists in using a solution containing EDTA complexes for elution of cesium radionuclides from the resorcinol-formaldehyde resin with their transition onto Thermoxid-35. High stability of the resorcinol-formaldehyde resin and Thermoxid-35 in the course of concentrating has been demonstrated. A scheme of deactivation of spent ion-exchange resins, which enables one to decrease the volume of secondary wastes due to utilization of a circulating water supply, has been suggested.

Theranostic Applications

AbstractAtherosclerosis is the major cause of cardiovascular diseases and is the leading cause of mortality worldwide. Iron oxide nanoparticles have emerged as potential diagnostic and therapeutic agents for a wide range of conditions. To date, the theranostic applications of iron oxide nanoparticles have been studied mainly in cancer, but atherosclerosis has not received the same attention. Therefore, it appears appropriate to review the current and future applications of iron oxide nanoparticles for the diagnosis and therapy of atherosclerosis. This review will first discuss current imaging techniques for the diagnosis of atherosclerosis as well as their limitations. It will then discuss the role of nanotechnology for molecular imaging of atherosclerosis and the benefits of this approach as well as reviewing current developments in the field including single, bi-, and tri-modal imaging. Next, it will discuss the role of nanotechnology for therapies of atherosclerosis with a focus on nanotheranostics, concluding with a look at the challenges faced by nanoparticle-based imaging and therapy of atherosclerosis as well as a look at future prospects.
