Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

open access: yesAdvanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

Solvent‐Free Phase Separation of Polystyrene‐block‐poly(2‐hydroxyethyl methacrylate) Forming Freestanding Photonic Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents a scalable, eco‐friendly approach to forming microstructured block copolymer (BCP) films within 15 min through hot pressing. This process enables phase separation even for high‐molecular‐weight BCPs, which are often trapped in spherical structures using time‐consuming solvent processes.

Thermal Resistance of 1D Micron‐Wide Interface Under External Force Modulation

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel TET‐based technique is developed to characterize the interfacial thermal resistance at the microscale. The interfacial thermal resistance is measured at ≈1200–1400 mK/W for natural contact. Externally applied force reduces the thermal resistance dramatically down to ≈125 mK/W.

Ultrasonic Spray Pyrolysis of Functional Zn─Sn─O Matrix Semiconductors: Stoichiometric Design for Enhanced Acetone Selectivity in VOC Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
Zn–Sn–O thin films synthesized via ultrasonic spray pyrolysis reveal tunable phase evolution and enhanced acetone selectivity. Integrating DFT insights with machine learning predictions uncovers the role of stoichiometric control and oxygen vacancies in VOC sensing.
