Article Synopsis
- The study focuses on the stability and behavior of ZnO ultrathin films on Pt(111) as nanocatalysts for CO oxidation, highlighting the importance of surface morphology and interface interactions.
- Dewetting occurs at the metal-oxide interface for films less than 1 monolayer, with different morphologies affecting their reactivity, particularly between (6 × 6) and (4 × 4) structures.
- Electronic properties change with film thickness, where thinner films display metallic behavior due to interactions with platinum, while thicker films exhibit semiconductor properties, influencing the design of more efficient ZnO-based catalysts.
Article Synopsis
- Ultrasound elastography technology is widely available, but quality processes for its implementation are often inconsistent, necessitating regular benchmarking by medical physicists.
- This study used two types of phantoms—a composite cylinder and an abdominal phantom mimicking liver fibrosis—to gather baseline data for quality assurance in elastography measurements across different manufacturers.
- Results indicated that ultrasound elastography measurements varied between manufacturers but were consistent within the same manufacturer, leading to established criteria for acceptable ranges in quality assurance testing for liver fibrosis.
The structural, spectroscopic and electronic properties of Na and K birnessites were investigated from ambient conditions (bir) to complete dehydration, and the involved mechanisms were scrutinized. Density Functional Theory (DFT) simulations were employed to derive structural models for lamellar AMnO·HO (A = Na or K, = 0 or 0.66), subsequently compared with the experimental results obtained for NaMnO·0.

Various pathogenic pathways contribute to liver inflammation, involving inflammatory polarization of macrophages and Küpffer cells, neutrophil infiltration, dysregulation of T cell subsets, oxidative stress, and activation of hepatic stellate cells. While mesenchymal stromal cells (MSCs) have demonstrated beneficial properties, their clinical translation is limited by their cellular nature.

However, these sizes of MPs are mostly overlooked due to different analytical challenges; besides, their pathways through atmospheric depositions, such as snow depositions, are mostly unknown. The spatial variability in bulk snow samples was investigated for the first time in distinct sites (e.
