A myriad of competitive intermolecular interactions have {thus|therefore|hence|as a result} far prevented a {fundamental|basic} understanding {of the|from the|in the|on the|with the|of your} {individual|person} and dual {role|function|part} {of these|of those} polar solutes upon amphiphile self-assembly in non-polar media. Toward this {end|finish}, the {current|present|existing} {work|function|perform|operate} employs classical molecular dynamics and intermolecular network analyses to deconstruct the {individual|person} {affects|impacts} of water and nitric acid upon the self-assembly of N,N,N\textsuperscript{$’$},N{$’$}-tetraoctyl-3-oxapentanediamide (TODGA), a prevalent amphiphile extractant {used|utilized|employed|utilised|applied|made use of} in metal ion separations. {In the|Within the|Inside the} absence of acid, and at low water concentration, H$_2$O is {found|discovered|identified|located} to {promote|market} {local|nearby|neighborhood|regional} dimer and trimer formation of TODGA, {however|nevertheless|nonetheless|even so|on the other hand|having said that} as [H$_2$O]$_{org}$ increases, preferential self-solvation {leads to|results in} {large|big|huge|massive|substantial|significant} (H$_2$O)$_n$ clusters that {cause|trigger|result in|lead to|bring about} TODGA clusters to sorb {to the|towards the|for the} (H$_2$O)$_n$ periphery and supports extended aggregation.
