On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions

Advanced Materials, EarlyView.
We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

Interfacial Behavior of Methane in Methane/p‐Xylene/Water Systems: First Principles Inspected Using Neutron Imaging and Molecular Dynamics Simulations

Advanced Materials Interfaces, EarlyView.
Pressurized gases reduce interfacial tension (IFT) at the gas‐liquid interfaces, their influence on the liquid–liquid interfaces remains unclear. For model compounds methane, water, and p‐xylene, neutron imaging observation of pressurized three‐phase systems is combined with Molecular Dynamics simulations.

Opportunities for Multiscale Pattern Modulation with Temporally Arrested Breath Figures

Advanced Materials Interfaces, EarlyView.
This works presents the temporally arrested breath figure methodology and its opportunities for pattern modulation. Through thermodynamic and photochemical phase change handles, this method uses drop‐wise condensation as a dynamic template for fast, accessible and scalable micropatterning.

Fabrication Method of Directional Microstructure for High Energy Density, High Power Battery Cathodes

Advanced Materials Interfaces, EarlyView.
Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...
