Air Layer on Superhydrophobic Surface Underwater
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2011Abstract Sustaining an air layer on superhydrophobic surface is known necessary for the applications of the “air layer effect” underwater on basis of previous literatures. However, the air layer becomes unstable when put underwater and even disappears when the hydraulic pressure increases. Thus much attention has been focused on the sustainability of

An Air Layer Modeling Approach for Air and Air/Vacuum Bearings
Journal of Manufacturing Science and Engineering, 1997Air layer supported bearing pads, or “air bearings” as they are commonly called, are popular because of their high load capacity and low in-plane coefficient of friction, making them well suited for supporting moving, high accuracy manufacturing stages. Air/vacuum bearings enhance these capabilities by giving the bearing pad load resistance capacity in

Propagation of Mangroves by Air-layering
Environmental Conservation, 1978The biological and geological importance of mangroves in coastal environs is well recognized. These halophytes contribute leaf-fall to marine food-webs, act as sediment stabilizers, and serve as a habitat for quite numerous organisms (Odum, 1971; Carlton, 1974; Walsh, 1974).

Radionuclides in the ground layer of air
Journal of Radioanalytical and Nuclear Chemistry Articles, 1990This work presents the results of gamma-spectrometric analyses of 24-hour aerosol samples collected on paper filters from the ground layer of air immediately after the Chernobyl accident, from 30th April to 4th May 1986. The results obtained by using carbon filters, highly effective for adsorption of iodine isotopes, are also given.

Surfactant layers at the air/water interface
Advances in Colloid and Interface Science, 2000The application of neutron reflectometry to the study of surfactant layers has been reviewed. Comparative assessment has been made of the information it yields concerning surfactant layers at the air/water interface and in micelles, where structural properties can be measured directly by neutron small angle scattering and less directly by techniques ...

Removable capping layer for air-sensitive GdN
Nanotechnology, 2020Abstract The strongly correlated rare earth nitrides display unusual coupled magnetic, electronic and superconducting properties, with predicted topological states. However, their air-sensitiveness has prevented in-depth investigations of their properties.

Dynamic Air Layer on Textured Superhydrophobic Surfaces
Langmuir, 2013We provide an experimental demonstration that a novel macroscopic, dynamic continuous air layer or plastron can be sustained indefinitely on textured superhydrophobic surfaces in air-supersaturated water by a natural gas influx mechanism. This type of plastron is an intermediate state between Leidenfrost vapor layers on superheated surfaces and the ...

Measurements in ablating air Teflon boundary layers
9th Aerospace Sciences Meeting, 1971Theoretical descriptions of the detailed structure of an ablating air-Teflon laminar boundary layer predict CF2 to be a major constituent in the boundary layer. This species has not been observed experimentally. This paper presents spectrally and spatially resolved uv thermal radiation measurements that demonstrate the presence of CF2 in the stagnation
