TL;DR: CNS imaging presentations targeted differentiating tumor, neural lesions, and necrosis from healthy brain tissue; methods of delivery of imaging agents across the BBB; and new iron oxide-based nanoparticle contrast agents for MR imaging.

TL;DR: FeNX in Fe single-atom catalysts can be the active site for adsorption and activation of reactants, and it has been shown to facilitate electron transfer between Fe and the carb.

TL;DR: In this article, a rotating disk electrode with a cavity that accommodates a wide range of granular iron powders has been used for environmental remediation applications, and it has been shown that most of the iron powder is electroactive, hydrogen evolution in the active region is kinetically limited, and iron dissolution in the inactive region is affected by mass transport of solutes out of the cavity pore space.

TL;DR: The stability of Tc(IV) depends on the solubility of the solid and susceptibility to reoxidation to TcO4, which in turn depend on the (biogeo)chemical conditions of the environment and/or nuclear waste streams as mentioned in this paper.
