Separation of Sc/Sc Nuclear Isomers Based on After-Effects.

Sc presents a particular interest for application in nuclear medicine for positron emission tomography (PET) due to its favorable nuclear decay properties ( = 3.97 h, = 1.47 MeV, branching ratio 94.

Thermoradiationally Modified Polytetrafluoroethylene as a Basis for Membrane Fabrication: Resistance to Hydrogen Penetration, the Effect of Ion Treatment on the Chemical Structure and Surface Morphology, Evaluation of the Track Radius.

A study of the properties of thermoradiationally modified polytetrafluoroethylene and its importance for use as the basis of polymer membranes is presented. The hydrogen permeability of a TRM-PTFE film was studied in comparison with an original PTFE film, and showed a three-fold decrease in hydrogen permeability. Further, TRM-PTFE films were irradiated with accelerated Xe ions with an energy of 1 MeV with fluences from 1 × 10 to 1 × 10.

An alternative radiochemical separation strategy for isolation of Ac and Ra isotopes from high energy proton irradiated thorium targets for further application in Targeted Alpha Therapy (TAT).

Targeted Alpha Therapy (TAT) has shown very high potential for the treatment of cancers that were not responsive to other therapy options (e.g., β therapy and chemotherapy).

Improved separation scheme for Sc produced by irradiation of Ca targets with 12.8 MeV protons.

Introduction: Sc is of great interest as a positron emission tomography (PET) radionuclide due to its suitable nuclear characteristics: E = 1.47 MeV, branching ratio 94.3% and convenient half-life of 3.

Synthesis of Silver Nanoparticles Using Reactive Water-Ethanol Extracts from .

Using the radiation-chemical simulation method of free radical reactions with 2,2-diphenyl-1-picrylhydrazyl, we were able to show high antiradical activity of water-ethanol extracts from . This will allow for the creation of new bioactive antioxidants based on them. The formation of silver nanoparticles (Ag-NP) was determined using the silver-ion reduction process by extracts.
