Adil Mughal, Ho-Kei Chan, Denis Weaire & Stefan Hutzler, Dense packings of spheres in cylinders: Simulations, Physical Review E, 85, (5), 2012, p051305-1 - 051305-17
Notes: [This paper presents additional simulation results regarding the densest packings of identical hard spheres inside a cylinder. For cases with a cylinder-to-sphere diameter ratio between 2.7013 and 2.873, a rich variety of structures, most of which consist of "internal" spheres that are not in contact with the cylinder, have been observed and identified. ]

Notes: [For the densest packings of identical hard spheres inside a cylinder, all the spheres will be in contact with the cylindrical surface if the cylinder-to-sphere diameter ratio is below the critical value 2.7013. This paper shows that such structures can be understood in terms of a distorted triangular lattice that describes the spheres' positions on the unrolled cylindrical surface.]

Ho-Kei Chan, Densest Columnar Structures of Hard Spheres from Sequential Deposition, Physical Review E - Rapid Communication, 84, (5), 2011, p050302-1 - 050302-4
Notes: [This paper shows that the densest packings of identical hard spheres inside a cylinder can be constructed from a surprisingly simple algorithm of sequential deposition if the cylinder-to-sphere diameter ratio is below the critical value 2.7013. The findings will have a broad range of applications in physics, from the macro- to the nano-scale, and also in commercial packaging.

Ho-Kei Chan & Ingo Dierking, Growth Models of Pure Supercooled Materials, Physical Review E, 77, (3), 2008, p031610-1 - 031610-6
Notes: [This paper presents an analytic derivation of two droplet growth laws which have been observed experimentally for a variety of condensed matter systems. The introduction of an additional length scale in the theoretical derivation solves the apparent contradiction between two conventional models for crystal growth.]

Notes: [This paper provides an explanation to the important experimental observation of polarization offsets in compositionally graded ferroelectric films. It presents a newly derived conductivity expression that could generally be applied for electrical space-charge-limited conduction in ferroelectrics and other solid dielectrics.
