Data‐Driven Modeling of Composition–Processing–Microstructure Relations for Recycled Aluminum Cast Alloys

open access: yesAdvanced Science, EarlyView.
Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Modulating Local Coordination in Single‐Atom Catalysts: From Fundamental Concepts to Emerging Breakthroughs in Electrocatalysis

open access: yesAngewandte Chemie, EarlyView.
This review summarizes atomic‐level design strategies for single‐atom catalysts, emphasizing modulation of the local coordination environment, active‐site geometry, and metal‐support interactions to optimize catalytic activity and stability in electrocatalytic energy conversion applications.

A Ceramic Network for Hybrid Solid Electrolyte Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
An in‐plane aligned Ta‐LLZO ceramic network exhibits superior performance compared to conventional fillers, including single ceramic fibers and particles. The tortuosity within the polymeric phase of hybrid solid electrolytes is identified as a key parameter governing lithium‐ion transport pathways and dendrite suppression.

An exciting Approach to Theoretical Spectroscopy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

Profilierung der Dokumentarischen Methode für das Forschende Lernen im Praxissemester am Beispiel einer Erhebung Subjektiver Theorien von Geschichtslehrenden

open access: yesHerausforderung Lehrer*innenbildung, 2018
Im Praxissemester wird die Gefahr eines „Imitationslernen[s] unterrichtspraktischer Fertigkeiten“ (Bach, 2013, S. 123) durch die in forschender Grundhaltung zu bewältigenden Studienprojekte gebannt.

Mapping Proton‐Coupled Electron Transfer With Real Space Coordinates

open access: yesAngewandte Chemie, EarlyView.
We explore how proton‐coupled electron transfer (PCET) proceeds on a potential energy surface defined by two coordinates for proton and electron transfer that are obtained from quantum chemical calculations. The two‐dimensional maps for PCET show distinct characteristics for concerted proton–electron transfer and hydrogen atom transfer.

CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

open access: yesAdvanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...
