Long-term stability of aerophilic metallic surfaces underwater
Trapped films of air known as plastrons are promising for underwater engineering but typically have short lifetimes. Here, aerophilic titanium alloy surfaces are developed with thermodynamically stabilized plastrons for antifouling applications.

Optical method for quantifying the potential of zero charge at the platinum–water electrochemical interface
The electric field created at an electrode–electrolyte interface can polarize the electrode’s surface and nearby molecules. Although its effect can be countered by an applied potential, quantifying the value of this potential is difficult. An optical method for determining the potential of zero charge at an electrochemical interface is now presented.

In situ imaging of amorphous intermediates during brucite carbonation in supercritical CO2
Non-classical crystallization may proceed through formation of intermediate phases, but it is not known whether these are linked to the final crystallization. Here, using an atomic force microscope at 90 bar, brucite carbonation is directly observed, with an amorphous intermediate acting as the seed for crystalline nesquehonite.

Single-layer ionic conduction on carboxyl-terminated silane monolayers patterned by constructive lithography
Local oxidation of the methyl groups of self-assembled silane monolayers into carboxylic acid functional groups allows the realization of solid ion-conducting channels, on top of which single layers of metal ions can drift when a voltage is applied.

Carbon monoxide-induced adatom sintering in a Pd–Fe3O4 model catalyst
Although the coarsening of catalytically active metal clusters can be accelerated by the presence of gases, the role played by gas molecules is difficult to ascertain. Carbon monoxide-induced coalescence of Pd adatoms supported on a Fe3O4 surface is now investigated at room temperature, and Pd-carbonyl species are shown to be responsible for their mobility.

Surface chemistry mediates thermal transport in three-dimensional nanocrystal arrays
The optical and electronic performance of inorganic nanocrystal assemblies stabilized by organic ligands has been extensively investigated, whereas less attention has been paid to their thermal transport properties. It is now shown that the thermal conductivity of these composite systems is determined by the vibrational states of both inorganic and ligand regions, as well as by their relative volumes.
