Publikováno v: Journal of Chemical Physics
Journal of Chemical Physics, 2022, ⟨10.1063/5.0124021⟩

Swollen cubic lyotropic ternary phases with Pn3m symmetry and reduced hardness were obtained from a specific binary mixture of cubic phase-forming (phytantriol) and lamellar phase-forming (decaglycerol monooleate) compounds. The microstructures were
