“…For the sake of completeness, we present below a brief overview of other experimental methods used to study adsorption–desorption mechanisms. In the 1970s, a technique relating the adsorbate structure determined by LEED (low energy electron diffraction) patterns with Clausius–Clapeyron analysis of equilibrium adsorption isosteres was commonly used to determine the binding energy. , More recently, desorption behavior of molecules was studied by the TD-XPS (temperature desorption X-ray photoelectron spectroscopy) method, a combination of desorption theory and surface spectroscopic techniques . The main disadvantage of these techniques is that they can be mainly used for studying reversible adsorption systems.…”

Surface calorimetry can be employed in the case of dissociative and reactive adsorption to measure the liberation of adsorption heat (ref 107 and references therein) and thus to derive the binding properties of the systems.…”

The evolution of star-forming regions and their thermal balance are strongly influenced by their chemical composition, which, in turn, is determined by the physicochemical processes that govern the transition between the gas phase and the solid state, specifically icy dust grains (e.g., particle adsorption and desorption). Gas–grain and grain–gas transitions as well as formation and sublimation of interstellar ices are thus essential elements of understanding astrophysical observations of cold environments (e.g., prestellar cores) where unexpected amounts of a large variety of chemical species have been observed in the gas phase. Adsorbed atoms and molecules also undergo chemical reactions that are not efficient in the gas phase. Therefore, the parametrization of the physical properties of atoms and molecules interacting with dust grain particles is clearly a key aspect to interpret astronomical observations and to build realistic and predictive astrochemical models. In this consensus evaluation, we focus on parameters controlling the thermal desorption of ices and how these determine pathways toward molecular complexity and define the location of snowlines, which ultimately influence the planet formation process. We review different crucial aspects of desorption parameters both from a theoretical and experimental points of view. We critically assess the desorption parameters (the binding energies, E b, and the pre-exponential factor, ν) commonly used in the astrochemical community for astrophysically relevant species and provide tables with recommended values. The aim of these tables is to provide a coherent set of critically assessed desorption parameters for common use in future work. In addition, we show that a nontrivial determination of the pre-exponential factor ν using transition state theory can affect the binding energy value. The primary focus is on pure ices, but we also discuss the desorption behavior of mixed, that is, astronomically more realistic, ices. This allows discussion of segregation effects. Finally, we conclude this work by discussing the limitations of theoretical and experimental approaches currently used to determine the desorption properties with suggestions for future improvements.

“…Surface analytical techniques yield detailed information on properties of surfaces. Since the advent of surface analysis techniques such as Auger electron spectroscopy or X-ray photoelectron spectroscopy (XPS) (Briggs and Grant, 2003) in the late 1960s, much insight has been gained into the nature and sources of surface contamination (Castle, 2008; Olivas et al., 1999; Tlili et al., 2012). Studies of carefully prepared metal surfaces yielded, e.g.…”

The ability of the cleaning agents such as cyclohexane, acetone, isopropanol and hydrogen peroxide to remove oil from technical steel and titanium samples was studied in systematic experiments. The composition of the organic residues and the layer thickness on the differently cleaned surfaces were determined via X-ray photoelectron spectroscopy analysis, and the corresponding water contact angles were measured. The ability of the cleaning agents to remove oil was found to increase in the following order: acetone, isopropanol, cyclohexane and hydrogen peroxide. The relationship between the chemical composition of the residues and the observed contact angles is investigated, and a quantitative correlation is developed.
