This review highlights how a Ir(III) and Ru(II) coordination complexes can change theirs cytotoxic activity by interacting with a biomolecules such as deoxyribonucleic acid (DNA), human albumins (HSA), nicotinamide adenine dinucleotide (NADH), and glutathione (GSH). We have selected biomolecules (DNA, NADH, GSH, and HSA) based on their significant biological roles and importance in cellular processes. Moreover, this review may provide useful information for the development of new half-sandwich Ir(III) and Ru(II) complexes with desired properties and relevant biological activities.

An original approach to characterize electrochemical interfaces at the atomic level, a challenging topic toward the understanding of electrochemical reactivity, is reported. We employed surface resonant X-ray diffraction experiments combined with their simulation using first-principle density functional theory calculations and were thus able to determine the molecular and electronic structures of the partially ionic layer facing the electrode surface, as well as the charge distribution in the surface metal layers. Pt(111) in an acidic medium at an applied potential excluding specific adsorption was studied.

Single-atom catalysts (SACs) dispersed on support materials exhibit exceptional catalytic properties that can be fine-tuned through interactions between the single atoms and the support. However, selectively controlling the spatial location of single metal atoms while simultaneously harmonizing their coordination environment remains a significant challenge. Here, we present a phenolic-mediated interfacial anchoring (PIA) strategy to prepare SACs with Fe single atoms anchored on the surface of heteroatom-doped carbon nanospheres.

Department of Rheumatology, Oslo University Hospital, Oslo, Norway.
Objectives: Juvenile idiopathic arthritis (JIA) originates from a complex interplay between genetic and environmental factors. We investigated the association between seafood intake and dietary contaminant exposure during pregnancy and JIA risk, to identify sex differences and gene-environment interactions.
Methods: We used the Norwegian Mother, Father, and Child Cohort Study (MoBa), a population-based prospective pregnancy cohort (1999-2008).
Single-Step Ethylene Purification and MTO Product Separation in a Nitrogen-Rich Microporous Metal-Organic Framework.

The nitrogen-rich metal-organic framework (MOF) , featuring a melamine (MA) functional group, enables efficient one-step CH purification and methanol-to-olefins (MTO) product separation. At 298 K, its adsorption capacity follows the order CH > CH > CH > CH. Breakthrough experiments showed that produced pure CH from C mixtures with a productivity of 22.
