Ag‐Cu Nanoarchitecture for Enhanced LSPR Absorption: the Role of Surface Roughness and near‐field Interactions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

open access: yesAdvanced 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.

Foams‐Induced Hierarchy for Multiscale Photonics on Flat Substrates: Lasing and Mie‐Bragg Diffraction as Case Studies.

open access: yesAdvanced Materials Interfaces, EarlyView.
Ordered and disordered complex configurations displaying two levels of functionality can be fabricated using a simple self‐assembly method involving the foaming and casting of suspensions containing monodisperse spheres on unpatterned flat substrates.

High‐throughput Photocatalytic Reactor With in Operando Characterisation for Fast Screening of Materials for the Photodegradation of Water‐Borne Pollutants

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel fast‐screening photocatalytic reactor system (FaS‐PhoReS) using terrestrial sunlight is able to measure the in operando photodegradation of 32 samples at once, and does not suffer from the common problem of sample evaporation. Four photostable 12 dyes are used to investigate the photocatalytic performance of TiO2 and ZnO samples in both film ...

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

open access: yesAdvanced 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.
