Oleoscopicity and Organic Deliquescence of Hydrophobic Compounds Under a Hydrocarbon Atmosphere

Journal of Physical Organic Chemistry, Volume 39, Issue 10, October 2026.
Hydrophobic compounds can acquire hydrocarbon vapor from organic‐enriched atmospheres and may deliquesce by dissolving completely in the acquired solvent. We report trends in oleoscopicity for a variety of organic compounds under an atmosphere of n‐hexane as a model hydrocarbon solvent. ABSTRACT This paper examines the acquisition of organic solvent by

Numerical investigation of the wake transition and aerodynamic efficiency of the two-dimensional propulsive wing

AIP Advances, 2022
The propulsive wing is a new concept wing of automatic propulsion with high lift coefficients and has great application value in plant protection and forest fire control. The propulsive wing wake is a reverse Bénard–von Kármán (RBvK) vortex street, which

Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...

Rotorcraft Safety: A Simulator-based Training Perspective [PDF]

, 2021
Training has the potential to inject a “safety vaccination” into the rotorcraft community by reducing the number of accidents. The term training should not be intended only in a strict sense, i.e., as pilot technical skills training, but more broadly as ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...
