Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Aqueous Synthesis of Poly(ethylene glycol)‐Amide‐Norbornene‐Carboxylate for Modular Hydrogel Crosslinking

Advanced Materials Interfaces, EarlyView.
An all aqueous synthesis of poly(ethylene glycol)‐amide‐norbornene‐carboxylate (PEGaNBCA) is developed via reacting carbic anhydride with amino‐terminated PEG. PEGaNBCA is readily crosslinked into hydrogels by click chemistries. PEGaNBCA crosslinked thiol‐norbornene hydrogels are hydrolytically stable but can be rendered hydrolytically labile through ...

Spatially Controlled 3‐D Multiplexed Aptamer Patterning in Hydrogels

Advanced Materials Interfaces, EarlyView.
A hydrogel platform based on norbornene‐functionalized polyvinyl alcohol enables high‐resolution, 3‐D multiplexed patterning of DNA aptamers via two‐photon polymerization. Two distinct aptamers are covalently immobilized with single micron‐scale precision across the x, y, and z dimensions.

Learning and Controlling Silicon Dopant Transitions in Graphene Using Scanning Transmission Electron Microscopy

Advanced Materials Interfaces, EarlyView.
Atomic transition rates for manipulating single silicon atoms in graphene with an electron beam in the scanning transmission electron microscope are experimentally extracted. Automated experiments and deep learning methods provide a means to probe and collect vast amounts of data to determine transition probabilities as a function of beam coordinate. A

Scaled‐Up Graphene Growth Through Chemical Vapor Deposition Over Large‐Area Liquid Cu Catalysts

Advanced Materials Interfaces, EarlyView.
Scaling up the catalyst area fivefold and improving molten catalyst cleaning minimize reactor kinetic effects, enabling reaction kinetics to dominate graphene growth. This results in high‐quality graphene with controlled layering and measurable nucleation rates.

Investigating the Mechanism of Ion Concentration Polarization Within Nanofluidic Hydrogel Membranes: Experiment and Simulation

Advanced Materials Interfaces, EarlyView.
Molecular dynamics simulations are employed to model ion concentration polarization (ICP) at the nanoscale, revealing fundamental electrokinetic behaviors that align with experimental observations. The study demonstrates how membrane charge, ionic strength, and electric fields affect ion localization and biomolecule trapping, providing mechanistic ...

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

Advanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

Advanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...
