Speed Control of Single Molecules on a Surface

Angewandte Chemie, EarlyView.
The speed of a single molecule moving across a silver crystal surface is determined with the tip of a scanning tunneling microscope (STM). Travelling distances Δx and travelling times Δt, which are determined simultaneously with high precision, allow to directly measure time–distance relationships.

Freedom dreaming of migrant justice: Critical reflections on counterspaces and institutional violence in the university

American Journal of Community Psychology, EarlyView.
Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

Biophysical Characterization and Proteomic Analysis of Small Extracellular Vesicles Derived From Different Neural Cell Lines

Advanced NanoBiomed Research, EarlyView.
This study systematically compares small extracellular vesicles (sEVs) derived from four neural cell lines, revealing how cellular origin shapes vesicle biophysical properties and proteomic cargo. Distinct, lineage‐specific signatures linked to neuronal, astrocytic, and microglial functions are identified, highlighting the importance of cell source ...

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation

Angewandte Chemie International Edition, EarlyView.
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.
