Summary: An electrochemical etching method for gold using [Tf2N](-) ionic liquids has been developed, which only requires one layer of iodine as a complexing ligand for gold dissolution and generation of gold nanoparticles. The voltammetric profiles of iodine-modified gold electrodes show that the electrochemical oxidation of gold is influenced by the type of halide ion and the crystallographic orientation of gold.

Summary: Detailed calculations of the specific absorption rate (SAR) of dilute iron oxide nanoparticles with effective uniaxial anisotropy dispersed in a liquid were performed, showing different behaviors depending on particle diameters and the alternating magnetic field, with the relationship to viscosity being dependent on nanoparticle size. The behavior of SAR was explained by viscous and magnetic oscillation modes, with SAR practically independent of viscosity in the magnetic mode.

Summary: The study developed a glass matrix for immobilizing radioactive iodine by incorporating transition metal oxides. The loading of iodine in the matrix was around 13-15% by weight, and the elements were retained without significant loss after melting the glass mixtures at 800 degrees C for 1 hour. The addition of WO3, MoO3, and V2O5 suppressed the release of iodine by densifying the TeO4 polyhedra.

Summary: In this study, iodine immobilization matrices were developed using lead oxide (PbO) or tellurium dioxide (TeO2) as additives in silver iodide-silver oxide-vanadium pentoxide glass systems. The waste form fabricated by melting at 800°C for 1 hour showed a weight percentage of 32-36% iodine loading in the matrix, with a normalized release of iodine and other elements that satisfied the USA regulation (< 2 g/m2). The addition of PbO and TeO2 suppressed iodine release but not silver release, indicating the structural factors affecting the chemical durability of the glass matrix were discussed.

Summary: An effective method for accelerating wound healing is through a smart delivery platform that releases drugs based on the different stages of healing. Electrospun nanofibers have gained attention due to their simple manufacturing process, unique structure, and biological functions similar to the extracellular matrix. In this study, a core-shell nanofiber platform loaded with two drugs was investigated, with the shell releasing the drug into an aqueous solution and the core generating localized heat for programmable drug release. This versatile platform can provide controlled and safe drug delivery to wound sites and potentially be used for treating other topical diseases.
