“…[19]) using 2-propanol as a solvent for the suspension. Solvent test indicated that longer chain alcohols lead to the best dispersion (for example, propanol works better than ethanol) of the IF-WS 2 ; alkanes were less efficient, and water led to the formation of a gel.…”

“…Thus, clearly water and pentane compete about identical adsorption sites. [37] In contrast, adsorption of pentane on a closed ice film should lead to a shift of the TDS peaks and different peak shapes compared with the clean silica support. [15,38] A diffusion of the nonpolar pentane through a thick and homogeneous ice layer appears unlikely.…”

JSC-1a (a simulated lunar dust sample) supported on a silica wafer (SiO 2 /Si(111)) has been characterized by scanning electron microscopy (SEM), energy dispersive x-ray (EDX) spectroscopy, and Auger electron spectroscopy (AES). The adsorption kinetics of water has been studied primarily by thermal desorption spectroscopy (TDS) and in addition by collecting isothermal adsorption transients. Blind experiments on the silica support have been performed as well. JSC-1a consists mostly of aluminosilicate glass and other minerals containing Fe, Na, Ca, and Mg, as characterized in detail in prior studies, for example, at NASA. The particle sizes span the range from a few micrometers up to 100 µm. At small exposures, H 2 O TDS is characterized by broad (100-450) K structures; at large exposures, distinct TDS peaks emerge, which are assigned to amorphous solid water (ASW) (145 K) and crystalline ice (CI) (165 K). Water dissociates on JSC-1a at small exposures but not on the bare silica support. Coadsorption TDS data (alkane-water mixtures) indicate that rather porous condensed ice layers form at large exposures, with the mineral particles acting most likely as nucleation sites. At thermal impact energies, the initial adsorption probability amounts to 0.92 ± 0.05. It is evident that the drop-and-dry technique, developed in studies about nanoparticles/tubes, can be extended to obtain samples for surface science studies based on powders consisting of particles with rather large diameters.

“…Multiple solute system. Most current research is focused on the adsorption of single solute [74,202,203] by CNTs in isolation and ignores any potential interactions between mixtures of multiple solutes that may affect adsorption. A multiple solute system may adequately represent the most of mixed contaminant systems commonly encountered in wastewater and natural water systems, where complex mixture of contaminants containing both heavy metals and organic contaminants or multiple organic contaminants may coexist at many contaminated sites.…”
