Monolithic integration of SiC diode detectors into scanning X‐ray microscopy optical elements for in situ beam diagnostics

Journal of Synchrotron Radiation, EarlyView.
Silicon carbide detectors are monolithically integrated into order‐sorting apertures and center stops for in situ soft X‐ray beam diagnostics in STXM. Functionalized components enable simultaneous monitoring of incident beam intensity and the transverse position at sample‐relevant locations without degrading optical performance.Reliable monitoring of ...

Advances in Floating Solar Desalination Systems

Water and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.

Large‐Aperture, WFOV Broadband Achromatic Metalens Enabled by Forward Mapping Optimization and Hybrid Algorithmic Framework

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A novel large aperture metalens design strategy achieves broadband achromatic imaging across the visible spectrum (400–680 nm) with a 100° field of view. By incorporating forward mapping optimization and a hybrid algorithm framework, this approach overcomes the limit between aperture size, field of view, and chromatic aberration correction, providing a

Interface‐Stabilized Glass‐Ceramic/Silver Composite Coatings Enable Predictable Multiband Infrared Stealth Under High‐Temperature Marine Environment

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a
