High‐Performance Flexible Near‐Infrared Organic Light‐Emitting Diodes with a Heterogeneous Alloy Semitransparent Electrode

Advanced Materials, EarlyView.
This study presents a micro‐structured magnesium‐bismuth alloy electrode that enhances flexible NIR OLEDs. The electrode provides 40% broadband transmittance (400–1600 nm) and boosts light outcoupling efficiency (42.3%) and photoluminescence quantum yield (71.8%) through the Purcell effect in optical microcavities.

Interactions between Cetyltrimethylammonium Bromide Modified Cellulose Nanocrystals and Surfaces: An Ellipsometric Study

Surfaces
The tailoring of the surface properties of cellulose nanocrystals (CNCs) to meet various requirements in environmental, food, and material areas has always been of great interest. In this study, the surface chemistry of CNCs was noncovalently modified by

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

Advanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.

Catch, Release, Repeat: Reversible Protein Capture in Electric Fields Using Antifouling Polymer Brushes

Advanced Materials Interfaces, EarlyView.
ABSTRACT Capturing proteins is easy since their amphiphilic nature allows them to bind to almost any surface. Because of this, releasing them is challenging since various interactions need to be considered for this. We present a simple method to reversibly adsorb proteins on stabilized electrodes.

Pulsed DC Sputter Deposition of Stable Turbostratic Boron Nitride Thin Films

Advanced Materials Interfaces, EarlyView.
Boron nitride (BN) films are deposited by sputtering from a boron target. During deposition, a substrate bias voltage is applied between the plasma and the sample, which reduces excess boron in the film and enhances the crystallinity. This process prevents the formation of boric acid and ammonium borate hydrate.

Simultaneous H2O:O2 Co‐Reactant Pulsing for Functional Property Control of Atomic Layer Deposited ZnO, TiO2, and Al2O3 Thin Films

Advanced Materials Interfaces, EarlyView.
Simultaneous H2O:O2 co‐pulsing in thermal ALD modulates surface hydroxylation to engineer nanovoids and properties in ZnO, TiO2, and Al2O3. The ligand‑dependent pathway promotes c‑axis‑textured ZnO, reduced‑crystallinity yet Ti4+‑preserved TiO2, and highly transparent, hydrophilic Al2O3, while lowering the refractive indices.
