Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

La nécropole mérovingienne de Metzervisse (Moselle)

open access: yesRevue Archéologique de l’Est, 2007
The Merovingian cemetery of Metzervisse was the object of a rescue excavation in 1995. The typo-chronological analysis of objects discovered in the graves enables us to date the cemetery from the 7th to – eventually – the 9th century AD.

Introducing Russia’s Media Aristocracy [PDF]

open access: yesRussian Politics, 2017
This collection of articles deals with the history and the current state of Russia’s media elite. It defines three groups of media elites; owners of media outlets, media managers and prominent journalists. All those groups are under pressure of being agreeable to the Kremlin and pleasing their audiences with their products and output.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Alkaios on the role of Mytilenian aristocracy in the economic life during stasis

open access: yesRUDN Journal of World History, 2021
The purpose of this paper is to analyze the evidence concerning different activities of aristocracy and if possible to define its role in the economic life during a very specific period in the history of archaic Mytilene, i.e. stasis.

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

open access: yesAdvanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

The Ni,Cd Heteroatoms‐Initiated Synergistic Tuning of Electron Configuration in Fe2VO4 Nanosheets Electrocatalysts to Profoundly Stabilize Alkaline Seawater Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
A Ni,Cd‐codoped Fe2VO4/NF bifunctional electrocatalyst is rationally designed for efficient seawater electrolysis. Synergistic effect modulates electron configuration, optimizes intermediates adsorption, stabilizes high‐valence Fe/V sites, and repels chloride ions to suppress corrosion and side reactions, thus contributing to performance improvement of
