Ques. Atoms of element Y form hexagonal close packing lattice and those of the element X occupy 1/4th of tetrahedral voids. What is the formula of the compound formed by the elements X and Y?(2 Marks) Ques. Mention some similarities between hexagonal close packing and cubic close packing.(...
stacking of close-packed planes leading to the HCP structure. 1. In FCC materials the third plane of atoms sits directly above the set of nests or hollows not chosen in atomic layer B. Therefore, this top row is displaced horizontally from both planes A and B and is designated as the C...

The SiO2 film in the two-dimensional ordered hexagonal close packing structure has the advantages of large area, high degree of order and small particle size; in addition, the film is highly controllable, the repeatability is high, and the cost is low....
employing in situ high-pressure synchrotron radiation X-ray diffraction, we reveal a polymorphic transition from face-centred-cubic (fcc) structure to hexagonal-close-packing (hcp) structure in the prototype CoCrFeMnNi high-entropy alloy... F Zhang,Y Wu,H Lou,... - 《Nature Communications》 ...
The hexagonal close-packed Pt–Ni excavated nano-multipods exhibit superior catalytic property towards the hydrogen evolution reaction in alkaline electrolyte. The overpotential is only 65 mV versus reversible hydrogen electrode at a current density of 10 mA cm À 2, and the mass current density ...
Crystal packingα-Amine oximesChiral complexAmong the crystal structures of molecular compounds, one of the most frequent packing mode, in topological terms, is the Distorted Hexagonal Close one of Voronoi prisms; its use in the description of a structure allows to establish molecule vs. packing ...
