Astatine-211 (211At or simply At) used as an α particle emitter is currently gaining treatment method for cancer cells. It must however be attached to a carrier facilitate the process. Gold nanoparticle good candidate that has been in several tests. Knowing physics behind adsorption of astatine on gold nanoparticles would advantageous designing more optimal such applications. We therefore perfo...

Halogen bonds mediated by iodine (Z = 53) can be more affected relativistic effects than halogen astatine 85).

A combined experimental and theoretical approach is used to define astatine (At) speciation in acidic aqueous solution and to answer the two main questions raised from literature data: does At(0) exist in aqueous solution and what is the chemical form of At(+III), if it exists. The experimental approach considers that a given species is characterized by its distribution coefficient (D) experime...

Benchmark quality geometries and interaction energies for the prereactive halogen-bonded complexes of dihalogens and ammonia, including hypothetical astatine containing dihalogens, have been produced via explicitly correlated coupled cluster methods. The application of local electron correlation partitioning reveals dispersion, electrostatics and ionic substitutions all contribute significantly...

Currently, thirty-nine astatine, thirty-nine radon,??? isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented. ∗Corresponding author. Email address: [email protected] (M.
