Exploring Local Structure in Iron Oxide Nanoparticles During Chemical Vapor Synthesis by in Situ and Operando X‐Ray Absorption Spectroscopy

open access: yesSmall Methods, EarlyView.
In situ and operando XAS is used to probe nanoparticle formation during chemical vapor synthesis, where particles form in the gas phase under high‐temperature conditions. XANES reveals dynamic changes to the oxidation states while EXAFS indicates local structural variations under in situ probing conditions.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

open access: yesAdvanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

Different Orbital Controls on Detrital Magnetic Components in the Ninety‐East Ridge Since the Late Pleistocene

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Magnetic minerals preserved in marginal‐sea sediments can serve as distinct fingerprints for unraveling paleoenvironmental evolution. However, the forcing mechanisms that govern the transport and accumulation of individual magnetic minerals at orbital timescales remain poorly constrained.

Insights Into the Oxygen Evolution Reaction on an Mn‐Bearing Hematite Electrocatalyst in an Acidic Electrolyte

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
This work investigates Mn incorporation into hematite‐based Fe1.5Mn0.5O3 and its impact on crystal structure and disorder using in situ high‐temperature XRD and quantum chemical calculations. Calcination controlled structural disorder enhances acidic OER activity, while operando Raman spectroscopy provides mechanistic insight into the roles of Fe and ...
