The phrase "air contact" is correct and usable in written English.
It can be used in contexts related to aviation, communication, or situations where contact is made through the air, such as radio signals or airborne interactions.
Example: "The pilot reported a loss of air contact with the control tower during the storm."
Alternatives: "aerial communication" or "atmospheric connection".
Every day for two months – albeit with breaks for applause, fresh air, contact with the outside world, and a drink.
It is important to wrap frozen meats closely in packaging that limits air contact with the meat in order to prevent moisture loss during storage.
Finally, it was found that H2 treatment avoids the formation of oxygen-containing groups during air contact leading to exfoliation of the graphite sample.
Damage profiles of the RC slab to air contact explosion using the three methods are compared with the experiment results in the literature, and the applicability and suitability of these methods are discussed.
The new system features bio-electrochemical system (BES) and integrates bio-filtration (trickling filter and air contact oxidation bed) and proton transfer through quartz sand chamber (QSC) which eliminates the use of expensive proton exchange membrane.
An air contact oxidation bed (ACOB) and embedded trickling filter (TF) with filled volcano rock, was designed to increase dissolved oxygen (DO) in cathodic EMBR to save aeration cost.
That frigid air contacts the water seeping through the pits and cracks in the concrete inner shell of the tunnel and turns it to ice, he said.
Further, the tight seal on newer housing may exacerbate problems during the heating of buildings, when humid indoor air contacts cold walls or windows (although the reverse is true for an air-conditioned building when it is hot outdoors).
The equilibrium water-in-air contact angles of measured poly(diol citrates) films ranged from 15° to 53°.
Produced polymer coatings were characterized with surface spectroscopy techniques (Raman and X-ray photoelectron spectroscopy, XPS) and water-in-air contact angle (WCA) measurements.
This can be explained naturally by the Cassie and Baxter model, that the trapped air among tubes would increase the liquid-air contact area, thereby forming bigger WCA.
