Advanced Science, EarlyView.ABSTRACT Strain is a proven technique for modifying the bandgap and enhancing carrier mobility in 2D materials. Most current strain engineering techniques rely on the post‐growth transfer of these atomically thin materials from growth substrates to target surfaces, limiting their integration into nanoelectronics.

Advanced Electronic Materials, EarlyView.A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Synthesis of Conjugated Linear and Cyclic Polyynes by Selective Alkyne Metathesis
Angewandte Chemie, EarlyView.The formation of polyynes with an odd number of conjugated triple bonds is challenging, particularly for complex architectures since most established methods rely on irreversible C–C bond‐forming reactions. To address this, we have developed the synthesis of triynes via alkyne metathesis.

Advanced Electronic Materials, EarlyView.Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Angewandte Chemie, EarlyView.Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...
