Autonomous Self‐Assembly of Ionic Nanoparticles into Hexagonally Close‐Packed Lattices at a Planar Oil–Water Interface

Chemistry - A European Journal (2012)

Volodymyr Sashuk Robert Hołyst Tomasz Wojciechowski Ewa Górecka Marcin Fiałkowski

Let's get charged! Positively charged nanoparticles (NPs) spontaneously self-assemble into hexagonally close-packed lattices at a planar CH2Cl2–water interface (see figure). The self-assembly process is fully autonomous and occurs without any external manipulation. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset. They are made available as submitted by the authors.

Cover Picture: Architecture and Evolution of Organic Chemistry (Angew. Chem. Int. Ed. 44/2005)

Angewandte Chemie International Edition (2005)

Marcin Fiałkowski Kyle J. M. Bishop Victor A. Chubukov Christopher J. Campbell Bartosz A. Grzybowski

Organic synthetic reactions are treated as a connected network so that the mechanism by which organic chemistry evolved can be studied. In their Communication on page 7263 ff., B. A. Grzybowski and co‐workers analyze organic syntheses reported between 1850 and 2004, thus revealing the architecture and evolution of the synthesis of molecules, and discuss the application of this technique to the chemical industry. The cover picture shows a typical “hub” in a network of organic chemistry.

Self-organization of planar microlenses by periodic precipitation

Journal of Applied Physics (2005)

Christopher J. Campbell Eric Baker Marcin Fiałkowski Agnieszka Bitner Stoyan K. Smoukov

Arrays of planar, Fresnel-like microlenses are prepared by a spontaneous chemical process of periodic precipitation (PP) occurring in a thin layer of a dry gel, and initiated by wet stamping. The PP lenses focus white light more efficiently than the conventional Fresnel zone plates of similar dimensions. Nanoscale topographies of the micropatterned gels can be replicated into transparent elastomers, and used for focusing based on optical path differences. Experimental observations for both types of structures are in agreement with the Fresnel diffraction calculations.

New One-Pot Technique to Introduce Charged Nanoparticles into a Lyotropic Liquid Crystal Matrix

Langmuir (2011)

Ewelina Kalwarczyk Maciej Paszewski Xia Xin Ewa Górecka Damian Pociecha

We present a new method to incorporate hydrophilic charged nanoparticles into the lyotropic liquid crystal (LLC) template. This method is based on the effect of the polymer-induced phase separation (PIPS) and consists of two steps. In the first step, the nanoparticles are mixed with a surfactant micellar solution. In the second step, upon addition of polymer, phase separation is induced and the LLC phase doped with the nanoparticles is formed. Columnar hexagonal and lamellar LLC templates are obtained with the PIPS method. The ordering of the LLC phase can be controlled by the amount of polymer added to induce phase separation. The method works both for the system of nonionic surfactants and polymers and ionic surfactants and polyelectrolytes. We demonstrate that the PIPS method enables the fabrication of the LLC templates doped with positively or negatively charged nanoparticles as well as with a mixture of oppositely charged nanoparticles in arbitrary proportions.

Wave Optics of Liesegang Rings

Physical Review Letters (2005)

Marcin Fiałkowski Agnieszka Bitner Bartosz A. Grzybowski

Liesegang rings refract and reflect at the interface between the regions of the same gel but of different thickness. The incident and the refracted rings obey a refraction law analogous to the Snell's law of classical optics, with a reverse of the spacing coefficient being a counterpart of the refraction index. The wavelike behavior of the rings at the interface is explained by geometrical arguments derived from the Jablczynski's spacing principle, and is reproduced in numerical simulations based on a three-dimensional minimalistic version of the nucleation-growth model.

A Morphological Study of the Formation of PdH_x on Thin Palladium Films

The Journal of Physical Chemistry B (2004)

Marcin Fiałkowski Robert Nowakowski Robert Hołyst

We propose a mechanism for the creation of the two-dimensional ridge pattern morphology during the formation of palladium hydride on the surface of thin palladium films at 298 K. Expressions for the distribution of domain areas and circumferences, derived from the maximum entropy principle, are in very good agreement with experiment.
