WebAn α-gel is a crystal retaining a large amount of water within the hydrophilic groups. The formation of a liquid crystalline phase or a gel phase is often observed in cosmetic emulsions. When a liquid crystalline phase or a gel phase appears in an emulsion, the physical properties like rheology and stability of the emulsion change ... WebApr 14, 2024 · In austenitic steels, the tetragonal Z-phase (NbCrN) has frequently been credited with beneficial strengthening effects during dislocation creep. In the modified Z-phase, niobium is partially substituted by vanadium. The basic objective of this contribution is a detailed characterization of the modified Z-phase in vanadium bearing austenitic …
WebThe amount of crystalline phase can vary over a wide range (1%–99%), but it is often in the range 30%–70%. Bioactive glass-ceramics have been studied and developed for bone and musculoskeletal tissue engineering for more than four decades ( Hench, 1998; Montazerian and Zanotto, 2016 ). Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the … See more In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material.
