Lipidic cubic phases: A novel concept for the

Understanding the mechanisms of action of membrane proteins requires the elucidation of their structures to high resolution The critical step in accomplishing this by x-ray crystallography is the routine availability of well-ordered three-dimensional crystals We have devised a novel rational approach to meet this goal using quasisolid lipidic cubic phases

Lecithin

Lecithin (UK: / ˈ l ɛ s ɪ θ ɪ n / US: / ˈ l ɛ s ə θ ɪ n / from the Greek lekithos yolk) is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues which are amphiphilic – they attract both water and fatty substances (and so are both hydrophilic and lipophilic) and are used for smoothing food textures emulsifying

film formation and perovskite crystallization processes in blade coating by engineering new ink design (Fig 1) We discovered that common solvents such as dimethyl sulfoxide (DMSO) and dimeth-ylformamide (DMF) do not favor fast deposition of a compact and smooth perovskite film at room temperature while highly volatile solvents of 2-methoxyethanol (2-ME) and acetonitrile (ACN) lead to
