Influence of the Crystal Structure of the Nucleus on the Morphology of t-ZnO Tetrapods

The state of individual layers and interfaces in multilayer nanostructures [(Co40Fe40B20)34(SiO2)66/ZnO/C]46

“…Both the structures have a similar form of tetrahedra, in the center of which are metal atoms surrounded by oxygen atoms at the vertices of the tetrahedra 22 . Theoretical calculations of the binding energy of ZnO equilibrium phases using a linear combination of atomic orbitals theory and density functional theory in approximations of both local density and generalized gradient demonstrate that the hexagonal structure is energetically more advantageous than the cubic one 22,23 . Therefore, there is an increase in the proportion of fragments of a more advantageous energy hexagonal structure as the thickness of the oxide layer increases.…”

The predominance of the hexagonal phase in the thickest ZnO layer observed from XRD is increased due to possible orientation of its structure in the direction of predominant growth (001) perpendicular to the substrate surface.…”

Влияние морфологических и структурных параметров тетраподов ZnO на их активность в реакции фотокаталитической деградации ципрофлоксацина

“…Tетраподы ZnO, обладающие увеличенной площадью поверхности, представляют собой самоорганизованные псевдотрехмерные наноструктуры, характеризуемые четырьмя монокристаллическими стержнями, исходящими из вершин тетраэдра. Такие материалы легко синтезируются в неравновесных условиях [10][11][12]. Несмотря на наличие совершенной монокристаллической основы, поверхность тетраподов в зависимости от метода синтеза может иметь дефектную структуру.…”
