Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

Advanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Flow‐Adaptive Gas Sensing Enabled Using a Uniform Au Nanosheet Sensor Array and a Neural Network Inference

Advanced Materials Technologies, EarlyView.
Integrated Au nanosheet sensor array enables simultaneous inference of gas concentration and flow rate via deep neural network analysis, without external flow control. ABSTRACT Gas sensor responses are considerably affected by gas flow rates, thereby inhibiting the accurate detection of target gas concentrations in variable‐flow applications such as ...

A Plug‐and‐Play Volume Minimizing Micromixer

Advanced Science, EarlyView.
ABSTRACT Microscale fluid mixing has numerous applications where rapid and efficient mixing is required, including drug discovery, bio‐analysis and point‐of‐care diagnostics. Conventional soft lithography processes, however, make the integration of robust and reliable mixing difficult to implement in practice, especially across different flow rates ...

Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor

Advanced Science, EarlyView.
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.

Single‐Atom Cobalt Species on Curved Hollow Carbon Sphere: Breaking Linear Scaling Relationship Limitations in Electrocatalytic Deactivation of Dilute Antibiotic Pollutants

Advanced Science, EarlyView.
A cobalt (Co)‐SACs consisting of single‐atom Co anchored on a nitrogen‐doped hollow porous carbon sphere (Co1/N‐HCS) is fabricated for electrocatalytic hydrodechlorination of dilute antibiotics. The hollow porous architecture of N‐HCS concentrates the antibiotics, while its curved surface promotes proton transfer at the Co1 site via localized electric ...
