Conversely, interfacial structuring of long-chain ILs in dry environments and at low surface charging is disordered and dominated by bulk structuring. Our results demonstrate that boundary conditions such as charging, confinement and doping by impurities have decisive influence on structure formation of ...
The interfacial structure of the IL remains relatively unperturbed when the liquid is in contact with CO . COadsorbs rapidly onto the liquid interface, forming a dense layer. Diffusion into the bulk occurs on a much slower timescale. Interfacial fluxes and diffusivities were determined. The ...
b, The crystallinity of the bulk sediment is visible through iridescence when left undisturbed. At 5 mM of NaCl, the assembly is still reconfiguring and delicate. After fixing through dilution and slowly drying, the hardened sediment retains iridescence, denoting retention of crystalline order. In ...
Under a Creative Commons license open accessHighlights Abstract In this work, we propose a computational methodology based on the state-of-the-art molecular simulations of IL/CuBTC composites composed of ILs having the same cation, 1-n-butyl-3-methylimidazolium ([BMIM]+), and various anions. ...
Additionally a study of the behavior of an ionic liquid, 1-ethyl-3-methylimidazolium triazolide (emim-TZL), under confinement was studied with MD simulation. Two different crystal faces of the Al2O3 crystal were used for confinement. Structure of the liquid at the interface and near the ...
bulk material response. We analyse a thick sample of K+β-alumina (Fig.3a) here to highlight this long time signal. We model the response as the sum of an instantaneous response arising from intrinsic nonlinearity and a mismatch in optical constants between the pump and probe frequencies44,...
Of relevance to energy storage, electrochemistry and catalysis, ionic and dipolar liquids display unexpected behaviours—especially in confinement. Beyond adsorption, over-screening and crowding effects, experiments have highlighted novel phenomena, such as unconventional screening and the impact of the electr...
Understanding ionic transport at the nanoscale is thus of fundamental importance for developing and optimizing this technology. Indeed, ionic transport at the nanoscale is not like that in the bulk, since the conductance-concentration dependence does not follow a linear bulk-like behavior at low salt...
(W) and height (H), should decrease owing to the increased number of crystal nucleus as well as the decreased space for crystal growth. The size decrease is beneficial for improving the value of confinement height according to Equation3. On the other hand, the increase ofmsand decrease of...
This trend for monovalent salts agrees with the expected enhanced deprotona- tion of silanol groups on the silica surface: ; SiOH R SiO2 1 H1 as electrostatic screening increases. Fitting the data with a basic Stern model (BSM)25 yields pKa ,7.5 for silanol deprotonation, in good agreement ...
