Mixed‐Dimensional Epitaxy of Aligned 1D vdW Nanowires on Low‐Symmetry 2D vdW Materials: Sb2X3 on ReX2 (X = S, Se)

Small, EarlyView.
Highly aligned mixed‐dimensional vdW heterostructures are achieved through vdW epitaxy of 1D Sb2X3 (X = S, Se) nanowires on low‐symmetry 2D substrates (e.g. ReX2). Reduced substrate symmetry enables aligned nanowire growth and well‐defined vdW interfaces. Atomic‐scale characterization reveals specific epitaxial relationships and stacking‐fault defects.

Unbiased Tandem System for Simultaneous Methane and Glycerol Upgrading to Formic Acid Under Ambient Conditions

Small, EarlyView.
A bias‐free photovoltaic‐photoelectrochemical tandem system enables simultaneous methane and glycerol upgrading to formic acid under ambient conditions. The cathode generates hydrogen peroxide for methane oxidation, while the photoanode efficiently oxidizes glycerol.

Crystallinity Effects on Near‐Infrared Photoresponse in Y6‐Based Organic Phototransistors

Small, EarlyView.
Solution‐processed Y6 thin films are investigated as active layers of organic field‐effect transistors and as near‐infrared photodetectors. Enhanced crystallinity in Y6 films induced by thermal annealing leads to improved charge transport and pronounced photoresponsivity.

Energy‐Level Engineering with Co‐Sensitization of Organic Molecules on NiOx for Sn‐Based Perovskite Solar Cells

Small, EarlyView.
Mixed molecular self‐assembly of functionalized bithiophene (BT) and dithienopyrrole (DTP) units on NiOx HTL synergistically modulate the Fermi Level to induce barrier‐free hole injection in both ITO/HTL and HTL/Sn‐perovskite interfaces in the inverted p‐i‐n device configuration.
