Ultraflat Templated Polymer Surfaces
Langmuir, 2009The roughness of spin-cast polymer films arises from thermally activated capillary waves during preparation and typically amounts to about 0.5 nm(rms) measured on a micrometer-sized surface area. Templating from atomically flat mica substrates allows the creation of polymer films with a surface roughness approaching the molecular scale.

Supramolecular Templates for Nanoflake–Metal Surfaces
Chemistry – A European Journal, 2009AbstractA sustainable method for the fabrication of metallic surfaces with flower‐like fractal morphology was developed by using a three‐dimensional supramolecular assembly as a template. Modifying Au nanoflakes with self‐assembled monolayers or polymers allows the surface wettability to be adjusted from superhydrophobic to superhydrophilic (see figure)

Nanoparticle‐Based Surface Templating
International Journal of Applied Ceramic Technology, 2011This study is focused on making molds with micrometer‐sized feature arrays, studying high solids loading nanoparticle suspension for nanoparticle‐based templating, and cast forming of surface‐templated materials. Polydimethylsiloxane (PDMS) and silicone molds with micrometer‐sized feature arrays are made using mold cores templated ...

Template recognition of protein-imprinted polymer surfaces
Journal of Biomedical Materials Research, 2000Synthetic materials capable of specifically recognizing proteins are important in separations, biosensors, and biomaterials. In this study, polysaccharide-like surfaces with tailored protein-binding nanocavities were prepared by a novel templating approach based on radiofrequency plasma deposition of thin films. The template-imprinted proteins included

Patterning Microsphere Surfaces by Templating Colloidal Crystals
Nano Letters, 2004By using the upper single or double layers in colloidal crystals as masks during Au vapor deposition, various Au patterns have been successfully constructed on the surfaces of the lower spheres. The dimension and geometry of the Au patterns obtained are dependent on the orientation of the colloidal crystal templates.

Surfaces: Two-Dimensional Templates
2008Producing nanoscale structures on solid surfaces in a controlled way is a technologicalchallenge that has an important impact on a variety of fields such as microelectronics, magnetic storagetechnology, and heterogeneous catalysis. Currently most processes are based on a top-down approach,which relies on an active patterning of a surface by, for ...

Surface chemistry of carbon-templated mesoporous aluminas
Physical Chemistry Chemical Physics, 2009Using infrared spectroscopy, a comparative investigation was carried out of the surface properties of mesoporous aluminas prepared by the carbon templating route and of a commercial alumina PURAL SB. In the hydroxylated state the mesoporous materials bear surface OH groups terminally bonded to an octahedral Al3+ ion, which has basic properties.

Surface-Templated Formation of Protein Microfibril Arrays
Langmuir, 2008Ordered arrays of collagen microfibrils form rapidly and spontaneously from a solution of monomers deposited onto a mica substrate. These arrays are well-ordered and apparently continuous over the entire substrate. Correlated atomic force microscope images and Laué diffraction patterns indicate that the protein alignment and microfibril formation is ...

Surface modeling using deformable templates
International Journal of Imaging Systems and Technology, 1991AbstractWe present a simple technique to model the structures and behaviors of flexible, elastic objects. We use an imaginary elastic wire frame, which is made of membranous, thin‐plate–type material, to model the surface structures of flexible objects.

Functionalized Supramolecular Nanoporous Arrays for Surface Templating
Chemistry – A European Journal, 2008AbstractControlled self‐assembly and chemical tailoring of bimolecular networks on surfaces is demonstrated using structural derivatives of 3,4:9,10‐perylenetetracarboxylic diimide (PTCDI) combined with melamine (1,3,5‐triazine‐2,4,6‐triamine). Two functionalised PTCDI derivatives have been synthesised, Br2–PTCDI and di(propylthio)–PTCDI, through ...
