Fabrication of Citric Acid/RGD Multilayers on Mg‐Zn‐Y‐Nd Alloy via Layer‐by‐Layer Self‐Assembly for Promoting Surface Biocompatibility

The multifunctional coatings of citric acid (CA) and tripeptide sequence Arg-Gly-Asp (RGD) via layer-by-layer self-assembly are immobilized onto the polydopamine (PDA) deposited surface which was passivated with hydrofluoric acid solution. The PDA/(CA-RGD)2 coating not only improves hemocompatibility of Mg-Zn-Y-Nd alloy, but also achieves rapid endothelialization...

Octylammonium Sulfate Decoration Enhancing the Moisture Durability of Quasi‐2D Perovskite Film for Light‐Emitting Diodes

The octylammonium sulfate decoration effectively enhances the moisture durability of PEA0.4CsPbBr3.4 quasi-2D perovskite film by the generated PbSO4 on the surface. The strong bonding interaction of SO4 2− and Pb2+ ions leads to reduced defect density, enhanced lattice stability, and robust PLQY of perovskite film. Abstract Quasi-2D perovskite...

Post‐Treatment of Screen‐Printed Silver Nanowire Networks for Highly Conductive Flexible Transparent Films

By employing a series of post-treatments after screen printing, silver nanowire (Ag NW) transparent conductive films with extremely low sheet resistance (0.72 Ω sq−1) are achieved. Integral printed patterns can be maintained during repeated water-washing, attributed to the enhanced substrate adhesion between the Ag NW networks and flexible poly(ethylene...

Surface Lattice Resonances in Self‐Templated Plasmonic Honeycomb and Moiré Lattices

Self-templated gold, silver, and binary gold/silver honeycomb and Moiré type lattices prepared by interface-mediated colloidal self-assembly support surface lattice resonances in the visible wavelength range. The resonance strength of the coupled modes is determined by the lattice constant and degree of order rather than the lattice type. Abstract...

Scalable Fabrication of Flexible Single‐Layer Strain and Double‐Layer Pressure Sensors by Inkjet Printing for Subtle Vibration Detection

Metallic silver layers are deposited onto polyurethane acrylate substrates with or without microstructures to form the flexible electrodes. The flexible flat electrodes can be applied as single-layer sensors with ultrahigh sensitivity. The combination of a flat electrode and a microstructured electrode finally becomes a durable double-layer flexible...

Direct Elimination of Detrimental Surface Phases Parasitic to LiNixCo1−xO2 (x = 0.8 and 0.9) with Unique 3D Porous Structures during Synthesis

An approach is proposed to directly eliminate detrimental rock-salt and spinel surface phases for nickel-rich layered oxides and other electrode oxides with unique 3D porous structures during synthesis without element doping and/or surface modifications involved which is simple, general, cost-effective, and upscalable. The as-obtained oxides exhibit...
