Origin of ion selectivity at the air/water interface.
Among many characteristics of ions, their capability to accumulate at air/water interfaces is a particular issue that has been the subject of much research attention. For example, the accumulation of halide anions (Cl(-), Br(-), I(-)) at the water surface is of great importance to heterogeneous reactions that are of environmental concern. However, the actual mechanism that drives anions towards...
متن کاملIon pair particles at the air-water interface.
Although the role of methanesulfonic acid (HMSA) in particle formation in the gas phase has been extensively studied, the details of the HMSA-induced ion pair particle formation at the air-water interface are yet to be examined. In this work, we have performed Born-Oppenheimer molecular dynamics simulations and density functional theory calculations to investigate the ion pair particle formatio...
متن کاملSpecific ion effects at the air/water interface.
Aqueous ion-containing interfaces are ubiquitous and play a key role in a plethora of physical, chemical, atmospheric, and biological processes, from which we mention just a few illustrative examples: (i) Ions at the air/water interface are important for atmospheric chemistry involving ocean surfaces and seawater aerosols,1-5 as well as that of the Arctic snowpack covered by sea spray.6,7 (ii) ...
متن کاملSelf-organization of discogenic molecules at the air-water interface
The behavior of several species of discogenic molecules at the air-water interface has been determined by measuring surface pressure vs. molecular area isotherms. Alkylthiotriphenylene derivatives do not appear to form monolayers at the interfaces, due to lack of amphiphilic character. Two truxene derivatives were found to display molecular areas on the order of 65 A2, most likely due to the mo...
متن کاملCyclodextrin-based self-assembled nanotubes at the water/air interface.
Native alpha-cyclodextrin (alpha-CD) is found to spontaneously form films at aqueous solution/air interfaces. Shape-response measurements to volume perturbations on drops hanging from a capillary indicate that temperature and sodium dodecyl sulfate (SDS) concentration strongly modify the viscoelastic properties of such films. By using isothermal titration calorimetry (ITC), Brewster angle micro...
