Epitaxial Growth of Polymer Crystals

Programmed crystallization via epitaxial growth and ligand replacement towards hybridizing porous coordination polymer crystals.

Hybridized porous coordination polymers (PCPs) are synthesized through epitaxial growth or ligand replacement. Whereas epitaxial growth on the core crystal leads to a sandwich type PCP, ligand replacement near the surface of core crystal results in a core-shell type PCP.

Growth of Multiple Crystals in Polymer Melts

The memory of surfaces: epitaxial growth on quasi-crystals.

If crystal structures can be viewed as repositories of information, then crystal surfaces offer a pathway by which this information can be used to grow new structures through the process of epitaxy. The information transfer process is one of self-organization, and the kinetic and energetic factors influencing this are complex. They include the relative strengths of the adsorbate-adsorbate and a...

Epitaxial growth of silver chloride crystals on bismuth oxychloride.

In this work, studies of morphological and structural characteristics of BiOCl/AgX heterostructures (X = Cl, I) synthesized using ion-exchange reactions have been conducted. It was found that silver chloride (AgCl) crystals precipitating on the surface of bismuth oxychloride crystals show orientation ordering with the (001)BiOCl||(100)AgCl crystallographic relationship. Using two synthesis rout...

GROWTH OF EPITAXIAL BaTiO

Metalorganic chemical vapor deposition (MOCVD) was used to deposit epitaxial BaTiO 3 thin films on (100) MgO substrates at 600'C. The metalorganic precursors employed in the deposition experiments were hydrated Ba(thd)2 (thd = CIIH190 2) and titanium isopropoxide. The films were analyzed by means of transmittance spectroscopy, wavelength dispersive x-ray spectrometry, secondary ion mass spectro...
