Condensation or Desublimation: Nanolevel Structural Look on Two Frost Formation Pathways on Surfaces with Different Wettabilities Open
Processes of water condensation and desublimation on solid surfaces are ubiquitous in nature and essential for various industrial applications, which are crucial for their performance. Despite their significance, these processes are not we…

Opportunities and new developments for the study of surfaces and interfaces in soft condensed matter at the SIRIUS beamline of Synchrotron SOLEIL Open
The SIRIUS beamline of Synchrotron SOLEIL is dedicated to X-ray scattering and spectroscopy of surfaces and interfaces, covering the tender to mid-hard X-ray range (1.1–13 keV). The beamline has hosted a wide range of experiments in the fi…

Fluorocarbon Vapors Slow Down Coalescence in Foams Open
Controlling the stability of liquid foams is of the utmost importance for a wide range of applications. For decades, fluorocarbon vapors have been added to the gas phase of foams to ensure long‐term stability against bubble coarsening. How…

Gel-to-gel non-variant transition of an organogel caused by polymorphism from nanotubes to crystallites Open
An organogel shows a gel-to-gel transition corresponding to the transformation of nanotubular aggregates into plain fibers, either by heating or aging. The domains of the existence of both gels are mapped in thec–Tphase diagram.

Cationic-Surfactant-Coated Mica Surfaces below the Critical Micellar Concentration: 1. Patchy Structures As Revealed by Peak Force Tapping AFM Mode Open
The morphology and structure of the self-assembled surfactant aggregates at the solid-liquid interface remain controversial. For the well-studied system of cationic cetyltrimethylammonium bromide (C16TAB) adsorbed onto the opposite negativ…

Direct Measurement of Lateral Correlations under Controlled Nanoconfinement Open
Lateral correlations along hydrophobic surfaces whose separation can be varied continuously are measured by x-ray scattering using a modified surface force apparatus coupled with synchrotron radiation, named SFAX. A weak isotropic diffuse …
