Photo‐Gated Corona Microfluidics

Advanced Science, EarlyView.
Photo‐gated corona microfluidics decouples optical programming from electric‐field actuation to enable reconfigurable manipulation on open, electrode‐pattern‐free surfaces. Near‐infrared irradiation locally melts paraffin, creating a reversible charge‐relaxation pathway that reconstructs the electric field.

[3,3]-Sigmatropic Rearrangements of Fluorinated Allyl (Thio)cyanates – A Tool for the Synthesis of Fluorinated (Thio)ureas

CHIMIA, 2014
The first (thio)cyanate to iso(thio)cyanate rearrangements based on 2-fluoroallylic alcohols are presented. Long-chain 2-fluoroallylic alcohols were converted to corresponding N-unsubstituted carbamates by treatment with trichloroacetyl ...

Diverging Liquid–Liquid Phase Separation Behavior of Different Recombinant Major Ampullate Spidroins

Advanced Science, EarlyView.
Fibers spun from the MaSp1‐derivative as well as MaSp1‐MaSp2‐mixtures provide a deeper insight into the assembly process of the spidroins and how hierarchical architectures of spider silk fibers could be achieved. ABSTRACT Spider silk fibers show exceptional mechanical properties, based on their underlying spider silk proteins (spidroins) as well as a ...

Design Rules for Quantitative Control of Intragrain Planar Defects in Halide Perovskites

Advanced Science, EarlyView.
Dose‐budgeted electron microscopy reveals the design rules governing intragrain planar defects in halide perovskites: {112}t ferroelastic twins proliferate with increasing tetragonality and grain size, whereas {111}c twins and stacking faults emerge as the lattice approaches cubic symmetry.

Grain‐Boundary‐Enriched Cocatalyst Coupled With CuSCN Hole Transport Layer for Efficient Solar Water Oxidation in BiVO4 Photoanode

Advanced Science, EarlyView.
A grain‐boundary‐enriched NiFe cocatalyst is coupled with a CuSCN hole transport layer on BiVO4 photoanodes. The integrated architecture promotes hole extraction, interfacial charge transfer, and surface OER kinetics, highlighting cocatalyst microstructure regulation as a complementary strategy to hole transport layer engineering. ABSTRACT Solar‐driven
