Controlling Frost Propagation on Polymeric Surfaces Using SI‐ATRP Chemical Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
Local wettability differences on the polymeric substrates grafted with hydrophilic stripes are linked to local variations in the presence and state of molecular water layer (MWL). The localized MWL results in fast‐propagating freezing events on the hydrophilic stripes followed by slower freezing propagation across the more hydrophobic substrate, thus ...

High‐Yield, Cost‐Effective Fabrication of High‐Aspect‐Ratio Polyimide Microstructures for Robust Superhydrophobic Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents robust polyimide superhydrophobic surfaces with excellent mechanical durability, thermal stability, and chemical stability. A high‐yield and cost‐effective method to fabricate high‐aspect‐ratio polyimide surface microstructures is developed by controlling the template surface treatment, precursor molecular weight, and vacuum process

Structural Insights Into Aluminum‐Doped Manganese Dioxides as Promising Materials for Direct Lithium Extraction: Modeling and Mechanism Study

open access: yesAdvanced Materials Interfaces, EarlyView.
A two‐stage sorption mechanism is proposed for Al‐doped HMnO in direct lithium extraction. Batch sorption experiments and modeling identify two key sorption sites on Al‐HMnO: surface sites (planar and edge) and vacancy sites (W). At pH 12, Stage I involves surface ion exchange, followed by Stage II, where surface complexation occurs between Li⁺ ions ...
