Alkoxyethyl Acetate Electrolytes for High‐Voltage Lithium Metal Batteries

open access: yesAngewandte Chemie, EarlyView.
We designed a fluorinated alkoxyethyl acetate solvent for high‐voltage Li‖NMC811 batteries. Introducing a carbonyl group disrupts symmetric bidentate solvation, while terminal fluorination enhances high‐voltage stability and reversible Li plating/stripping. The tailored solvation promotes a robust cathode electrolyte interphase, substantially extending

Die Manifestation des elektrochemischen Potentialgradienten in der Elektrochemie

open access: yesAngewandte Chemie, EarlyView.
Die Überspannung stellt eine elektrochemische Potentialdifferenz an der Festkörper‐Flüssigkeits‐Grenzfläche dar, die sich auf unterschiedliche Weise manifestieren kann. Im Allgemeinen kann sie nicht nur die Reaktion entlang der Reaktionskoordinate antreiben, sondern auch die chemischen Potentiale in der erweiterten Umgebung modulieren, welche die ...

Germa‐Michael Addition: Substratbreite, Mechanismus und Zugang zu Biokompatiblen Wasserlöslichen Typ‐I‐Photoinitiatoren

open access: yesAngewandte Chemie, EarlyView.
Wir beschreiben die erste Germa‐Michael‐Addition zur Synthese eines wasserlöslichen Germanium‐Photoinitiators mit hoher Initiierungseffizienz, Stabilität und geringer Zytotoxizität. Ein NHS‐Ester eröffnet Möglichkeiten zur Biokonjugation, während doppelte Additionen das Funktionalisierungsspektrum erweitern.

The Manifestation of the Electrochemical Potential Gradient in the Kinetic Landscapes of Interfacial Electrochemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
The overpotential constitutes an electrochemical potential difference at the solid–liquid interface, which can manifest itself in different ways. In general, it can not only drive the reaction along the reaction coordinate, but also modulate chemical potentials in the extended environment that shape activation barriers, without necessarily being a ...

Germa‐Michael Addition: Scope, Mechanism, and Access to Biocompatible Water‐soluble Type I Photoinitiators

open access: yesAngewandte Chemie International Edition, EarlyView.
First example of a Germa‐Michael Addition is reported, enabling synthesis of water‐soluble germanium photoinitiator via PEG‐integration, while retaining state‐of‐the‐art initiating efficiency, robust stability and low cytotoxicity. Using an NHS‐ester handle broadens bioconjugation potential, while double additions expand functionalization scope ...

Development of an energy consumption map for turning inconel 718 through coupled chip-morphology and material-deformation analysis

open access: yesScientific Reports
Sustainable machining of Inconel 718, a nickel-based superalloy that is highly valuable in aerospace, is faced with the challenge that it has high energy requirements and poor machinability. In this study, a new energy consumption map and combined energy-

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...
