Paragraph needs editing
[edit]This whole paragraph in Gel formation and morphology needs editing: "Traditionally, gel phase transitions are strictly temperature dependent. However, it has recently been shown that non-liquid crystalline gelators, composed of (R)-18-(n-alkylamino)octadecan-7-ols (HSN-n), undergo first order gel-to-gel phase transitions; leading to different morphologies of the gel in carbon tetrachloride (CCl4).[6]" Different than in what?
"The uniqueness of this discovery stems from the idea that it is..." Bloated formulation.
"...the solvent molecules entering and exiting the structure which leads to the different structural morphologies. All other previously known gel phase transitions have occurred as the result of temperature changes and only one previous case documents this type of solvent dependent morphological change." I don't think that is true. Could someone clarify what this means? Gel morphology is STRONGLY dependent on the nature of the solvent. In every LMOG.
"However, even in the case of N-isopropylacrylamide hydrogels that underwent conformational changes (folding and unfolding of their polymer chains); it occurred only via a temperature dependent process which resulted in water molecules, near the structure, entering or exiting the structure.[7][8][9][10] The stability of a formed gelation matrix is dependent on the equilibrium between the assembled network and the dissolved gelator assemblies." So the stability is dependent on.. the stability? That's what the equilibrum is.
"LMOGs are functionally diverse and can be composed of both polar and non-polar regions (amphiphiles)." While this is true, it has nothing to do with the rest of the paragraph.
Edit: After reading the abstract of the paper that is cited within [6], I understand what the special point is. The gel can undergo structural changes without going into the sol state, but directly from gel to gel. But I think that is special knowledge and doesn't fit within the frame of an encyclopedia article. 60.33.115.55 (talk) 00:39, 26 September 2017 (UTC)
