WebOnly a lamellar LLC phase is formed by L62, while P105 is capable of self-assembling with increasing polymer concentration into (body-centered close-packed) cubic, hexagonal, and lamellar LLC phases. Upon heating, the LLC phases of the L62-water and L64-water systems swell with water; no such swelling is detected for the P105-water system. Web5 apr. 2024 · 3.1.DSPC in EAN phase behaviour. Near room temperature, DSPC forms a lamellar crystalline phase, L c, phase at EAN content below 20% w/w and a lamellar gel phase, L β, at higher EAN concentrations between 40 and 60% w/w.Between these lies a broad L c + L β coexistence region, and L β coexists with excess EAN above its …
WebIn a close packing, the number of octahedral voids is equal to the number of atoms and the number of tetrahedral voids is twice the number of atoms Since all the octahedral voids and half the tetrahedral voids are filled there will be one atom of B in tetrahedral void and one atom in octahedral void corresponding to each A. WebUsually the larger anions make up the framework of the crystal lattice and the smaller cations then occupy the spaces or holes left between the framework of anions. Packing arrangements like simple cubic (sc), …

WebSol: Hexagonal close packing has an array of oxide ions, where two out of three octahedral holes occupied by Fe3+ ions has one octahedral void or holes corresponding to each atom constituting the close packing. In iron oxide only 2/3 of octahedral holes are occupied by Fe3+ ions. It means corresponding to each oxide ion, there are 2/3 Fe3+ ions. kathryn rafferty npWebBecause closer packing maximizes the overall attractions between atoms and minimizes the total intermolecular energy, the atoms in most metals pack in this manner.
