High‐Throughput Screening of REBCO Superconducting Thin Films Fabricated Via Combinatorial Inkjet Printing and TLAG Process

Advanced Materials Technologies, EarlyView.
A methodological framework is presented for combinatorial REBCO thin films fabricated by drop‐on‐demand inkjet printing with controlled Rare Earth composition gradients. Automated, synchrotron‐based, and local characterization techniques produce comprehensive property maps that correlate composition and TLAG process parameters with superconducting ...

Decoupling the Impact of Deep‐Trap and Band‐Tail States on PbS Quantum Dot Photodetectors via Alkylamine Engineering

Advanced Materials Technologies, EarlyView.
Band‐tail and deep trap states are effectively disentangled through the use of selective alkylamine additives. PA‐driven 2D ordering narrows band tails, while HA enhances halide passivation and Pb coordination to suppress deep traps. A comparative study of their CQD short‐wave infrared (SWIR) photodetectors further reveals whether band‐tail states or ...

Controlling Ultrafast Photonic‐Plasmonic Coupling in a Hybrid Platform for Biosensing Applications

Advanced Optical Materials, EarlyView.
A metal–dielectric hybrid composed of gold nanocaps on opal exhibits a broad near‐infrared plasmonic resonance interacting with the photonic bandgap under ultrafast transient conditions. This coupling can be controlled by varying the excitation wavelength and is responsive to bacterial deposition, opening new opportunities for ultrafast biosensing ...

Beyond Brown: Lignin's Emerging Role in Structural Color

Advanced Optical Materials, EarlyView.
Lignin, long regarded as a brown industrial byproduct, is emerging as a sustainable platform for structural color. This Perspective highlights how lignin's refractive index, intrinsic absorption, and nanoscale assembly enable tunable photonic responses in colloidal and thin‐film architectures, and outlines design strategies to advance scalable, bio ...
