Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy

open access: yesAdvanced Materials, EarlyView.
SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well

Microbubble Shell Stiffness Engineering Enhances Ultrasound Imaging, Drug Delivery, and Sonoporation

open access: yesAdvanced Materials, EarlyView.
 Shell‐engineered poly(alkyl cyanoacrylate) microbubbles with tunable stiffness improve ultrasound imaging and therapy. Adjusting the length of the alkyl chain and the glass transition temperature maintains a narrow microbubble size distribution while enhancing drug loading, sonoporation and the acoustic response.

Supramolecular Interface Engineering via Interdiffusion for Reusable and Dismantlable Polymer Adhesion

open access: yesAdvanced Materials, EarlyView.
Reversible adhesion via host–guest complex formation at the polymer interface is achieved by externally controlling the complexation through applied stimuli. Neutron reflectometry analysis of the adhesion interface revealed that the presence of host–guest complexes hinders the polymer interdiffusion by despite promoting adhesion strength.

Light‐Driven Reconfigurable Logic in a Monolithic Perovskite Device via Nonlinear Photoresponse Switching

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a monolithic perovskite OELG device that performs all eight logic operations, including XOR and XNOR, without external bias. Enabled by trap‐engineered MAPbI3:PLL and dual photogates, it achieves reconfigurable logic and parallel decoding of amplitude–frequency signals, supporting scenario‐configured logic‐level separation for ...
