Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Tailoring surface structures for enhanced single‐droplet jumping condensation

Droplet, Volume 5, Issue 4, October 2026.
Hierarchically structured superhydrophobic surfaces enable single‐droplet jumping during condensation, promoting continuous surface refreshment and enhanced heat transfer. By combining micro‐ and nano‐scale textures, the optimized design of micropillars enhances the frequency and efficiency of single‐droplet jumping events.

Lysine‐Functionalized Boehmite/Polysulfone Nanofiltration Membranes with Enhanced Dye Rejection and Salt Separation Performance

Macromolecular Materials and Engineering, Volume 311, Issue 10, October 2026.
Lysine‐functionalized boehmite (Lys‐BM) enhances polysulfone membrane hydrophilicity, permeability, antifouling performance, and separation efficiency. Incorporation of Lys‐BM reduces the water contact angle from 65° to 52°, doubles pure water flux, increases flux recovery to 91.5%, and achieves over 95% methylene blue and 90% Mg rejection ...
