For the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (Ni) modified composite graphite (CG) electrode (hcp-nano Ni/CG) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 M KOH). The hcp-nano Ni/CG electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare CG. The elec...

The hard sphere model is known to show a liquid-solid phase transition, with the solid expected to be either face centered cubic or hexagonal close packed. The differences in free energy of the two structures are very small and various attempts have been made to determine which structure is the more stable. We contrast the different approaches and extend one.

Large defect-free domains of a hexagonal packed monolayer silica spheres with the size 4000 µm2 were successfully prepared by dual-speed spin coating. Experimental design and statistical analysis instead traditional ‘changing one separate factor at time’ (COST) approach employed to guide implementation experiments. With its assistance, hexagonal-close-packed (HCP) percentage was elevated 84% in...

Abstract This study develops a new phenomenological constitutive model to capture the unique evolving cyclic elastoplastic behaviours of hexagonal close-packed (HCP) sheet metals. is developed by adopting concepts multiple-yield surface approaches. Four deformation modes, including Monotonic Compression (MC), Tension (MT), Reverse (RC), and (RT), are considered represent hardening evolution mat...

The colloidal synthesis of hcp silver microparticles is optimized by tuning the chemical reduction kinetics and surface stabilization during synthesis.

A combination of grazing incidence X-ray reflection/diffraction (GIXR/GIXD) and atomic force microscopy have been used to study the 3D structure in cadmium arachidate (CdA) and single phase zinc arachidate (ZnA) LB multilayers. The CdA multilayers have an ideal close packed herringbone structure. The molecules have a non-centred in-plane arrangement with specific orientational relation between ...
