In our continued exploratory synthesis of compounds containing transition-metal oxide magnetic nanostructures, a new copper(II) phosphate phase, Cs2Cu3P4O14 (1), was isolated employing the mixed CsCl/2CsI molten flux. The X-ray single-crystal structural analysis shows that the Cs2Cu3P4O(14) phase crystallizes in a mon…

The nano-phase-separation in mixed polymer brushes consisting of polystyrene and poly(methyl methacrylate) (PS-PMMA) chains attached to a silicon surface is studied. The topographies of the mixed brushes are examined after they have been exposed to solvents which induce or erase nano-phase-separation. It is discussed…

X-ray absorption spectroscopy at the Cr K- and L(2,3)-edges was used to study the assembling process of a heterogeneous Cr-based single-site catalyst. The starting point was a Phillips-type system with monochromate species anchored on a silica surface, which was first reduced to a variety of different surface Cr(II) s…

The stochastic nature of percolation is shown as a possible issue for retention in PCM devices, due to the occurrence of unlikely crystallization events that early decrease the device resistance. Failure time dispersions at high temperatures are measured and analyzed through a crystallization Monte Carlo model. A phys…

We study the problem of nonlinear development of oscillatory convective instability in a two-dimensional mushy layer during solidification of a binary mixture. We adopt the near-eutectic limit, making the problem analytically tractable using standard perturbation techniques. We consider also a distinguished limit of l…

Controlling the spatial distribution of liquid droplets on surfaces via surface energy patterning can be used to deliver material to specified regions via selective liquid/solid wetting. Although studies of the equilibrium shape of liquid droplets on heterogeneous substrates exist, much less is known about the corresp…

Protein-mediated biomineral formation and polymorph selection in the mollusk shell involves the participation of a number of different proteins. One of these proteins, AP7, has been identified as a participant in nacre (aragonite) formation in the mollusk Haliotis rufescens. However, the role(s) of this protein in ara…
