The interest in zirconium-89 (89Zr) as a positron-emitting radionuclide has grown considerably over the last decade due to its standardized production, long half-life of 78.2 h, favorable decay characteristics for positron emission tomography (PET) imaging and its successful use in a variety of clinical and preclinical applications. However, to be utilized effectively in PET applications it mus...

Titanium oxide (rutile, TiO2) and zircon (ZrSiO4), known insoluble ceramic materials, are commonly used for coatings of implant materials. We investigate the release of zirconium, titanium, aluminum, iron, and silicon from different micron-sized powders of 6 powders of natural rutile (TiO2) and zircon (ZrSiO4) from a surface perspective. The investigation includes five different synthetic body ...

Unique classes of active-site motifs are needed for improved electrocatalysis. Herein, the activity a new catalyst motif is engineered and isolated oxygen evolution reaction (OER) created by nickel–iron transition metal electrocatalysts confined within layered zirconium phosphate matrix. It found that with optimal intercalation, NiFe catalysts have an order magnitude mass compared to more conve...
