“…For salty water, both density and surface tension change, but the variations do not exceed 10 % (Kalová and Mareš, 2018;Wang et al, 2018;Wen et al, 2018) and can be neglected, in full agreement with the experiment, which did not show significant salinity-driven variations.…”

Abstract. A new bubble-generating glass chamber with an extensive set of aerosol production experiments is presented. Compared to the experiments described in the literature since the ground-setting works of Edward C. Monahan et al. in 1980s, the current setup is among the medium-sized installations allowing for accurate control of the air discharge, water temperature, and salinity. The size and material of the chamber offer a variety of applications due to its portability, measurement setup adjustability, and sterilization option. The experiments have been conducted in a cylindrical bubbling tank of 10 L volume that was filled by ∼ 30 %–40 % with water of controlled salt content and temperature and covered with a hermetic lid. The chamber was used to study the characteristics of aerosols produced by bursting bubbles under different conditions. In line with previous findings, the sea spray aerosol production was shown to depend linearly on the surface area covered by the bubbles, which in turn is a near-linear function of the air discharge through the water. Observed dependencies of the aerosol size spectra and particle fluxes on water salinity and temperature, being qualitatively comparable with the previous experiments, substantially refined the existing parameterizations. In particular, the bubble size was practically independent from the air discharge through the water body, except in the case of very small flows. Also, the dependence of aerosol spectrum and amount on salinity was much weaker than suggested in some previous experiments. The temperature dependence, to the contrary, was significant and consistent, with a transition in the spectrum shape at ∼ 10 ∘C. Theoretical analysis based on the basic conservation laws supported the main results of the experiments but also highlighted the need for a better understanding of the aerosol production from a cold water surface.

“…( 6). The second phenomenon is more complicated but presumably small: the variations of water viscosity and surface tension are within 10 % for the realistic salinity range (Kalová and Mareš, 2018;Wang et al, 2018;Wen et al, 2018). It is also visible in Fig.…”

“…It is known that in equilibrium the pressure inside a spherical drop of radius r differs from the ambient pressure (Young–Laplace equation): where P d is the pressure inside the drop, P 0 is the ambient pressure, and σ is the surface tension of the liquid. On the contrary, it is well-known that the surface tension of water decreases with increasing temperature . Thus, heating of the droplets will shift the equilibrium and the increased pressure inside the droplet can lead to its explosive breakup .…”

Aerodynamic thermal breakup droplet ionization (ATBDI) in mass spectrometric drug analysis is considered. Cocaine, heroin, and the main alkaloids of opium (morphine, codeine, papaverine) were chosen as the test compounds. The principles of ATBDI ionization are discussed. The dependences of the intensities of the peaks of the target compounds on temperature during ATBDI ionization are also considered. In some cases, a comparison of ATBDI ionization with electrospray ionization (ESI) was performed. In addition, a comparison of methods is demonstrated by the analysis of confiscated opium that was provided by the local police department. Five major alkaloids are found in opium: morphine, codeine, thebaine, papaverine, and narcotine.

“…Under these conditions the viscosity of liquid water remains around 1.6 × 10 −3 Pa s (Pigott, 2011), because the influence of pressure appears negligible (Pigott, 2011). Similarly, the surface tension of water is expected to be close to the room conditions value, that is, 76 mN m −1 (Kalová & Mareš, 2018). On the Earth, there are countless examples of hydrophobic natural organic matter.…”

The Earth is no longer the only known celestial body containing one or more liquid phases. The Cassini spacecraft has discovered seas of hydrocarbons at the surface of Titan, while a series of corroborating evidences argue in favor of the existence of an aqueous ocean beneath the icy crust of several moons. Capillarity embraces a family of physical processes occurring at the free surface of a liquid. These phenomena depend on the liquid properties and on the local planetary conditions. Capillarity may have important direct or indirect implications on the geoscientific and astrobiological points of view. In this paper, we discuss capillarity physics among solar system objects and expected consequences for planetary science.
