Dysprosium-doped ZBLAN fiber laser tunable from 2.8 {\mu}m to 3.4 {\mu}m, pumped at 1.7 {\mu}m

, 2018
We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 {\mu}m Raman fiber laser. To the best of our knowledge, this represents the largest tuning range achieved to date from

Biomimetic Organic Nanozyme as Tumor Vaccines for Targeted Suppression of Ammonia‐Induced T Lymphocyte Death to Augment Breast Cancer Immunotherapy

Advanced Science, EarlyView.
The organic nanozyme IR‐IHpd, which has NIR‐PDT and POD‐like activity, is designed for continuous ROS generation. It is co‐encapsulated with CB‐839 and coated with DC membranes to simultaneously target tumors and T cells. Under NIR irradiation, immunogenic cell death is activated. Concurrently, CB‐839 suppresses ammonia‐induced T lymphocyte death (AITD)

Potential of Y₂Sn₂O₇:Eu³⁺, Dy³⁺ Inorganic Nanophosphors in Latent Fingermark Detection

Crystals
In this work, we investigated the potential of Eu3+/Dy3+-codoped Y2Sn2O7 fluorescent nanophosphors to visualize latent fingermarks. We prepared these nanophosphors with various doping concentrations by the conventional coprecipitation reaction.

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

XOR‐Logic Phase Coding Programmable Metasurface for Low Power‐Consumption Systems

Advanced Science, EarlyView.
By leveraging XOR logic, the biasing‐network complexity of 2D programmable metasurfaces is reduced from m×n to m+n through efficient row‐column control. This enables versatile functions including beam deflection and beamforming, facilitating applications in wireless communications and beyond.

Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces

Advanced Science, EarlyView.
Tunable sound absorption is realized through a bilayer metasurface system governed by evanescent‐wave coupling. This work demonstrates that such evanescent‐wave coupling provides a controllable scattering channel that destructively interferes with the specular reflection.

Outstanding 1200 °C Oxidation Resistance in a Novel Multi‐Principal Element Alloy via Lattice Distortion‐Induced Diffusion Suppression

Advanced Science, EarlyView.
The unique lamellar structure of the eutectic alloy promotes selective oxidation of Al initially, while lattice distortion‐induced diffusion suppression slows oxide growth during steady state. Combining these strategies, a Multi‐Principal Element Alloy with excellent oxidation resistance at 1200℃ was designed.
