Of Substitution and Doping: Spatial and Electronic Structure in Fe Pnictides
, 2016 A highly intriguing aspect in iron-pnictide superconductors is the composition-dependent electronic structure, in particular the question if and how charge carriers are introduced to the system upon substitution of Ba by alkali metals or of Fe by other ...

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers
Sedimentology, EarlyView.ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Exploratory XPS Evidence for Ca–N Environments at the Organic–Mineral Interface in Bone
Surface and Interface Analysis, Volume 58, Issue 6, Page 369-374, June 2026.ABSTRACT Bone derives its remarkable mechanical properties from the nanoscale relationship between its organic matrix and mineral components. While interfacial interactions are known to affect bone mechanics, direct evidence of chemical bonding at this interface has been lacking.

Advanced Functional Materials, Volume 36, Issue 34, 27 April 2026.A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...
