چکیده

Binding sites analogous to those of sp(3) carbon are presented by concanavalin A. This lectin has now been cross-linked with a bismannopyranoside which contains the C(2) spacer required to form the computer-modeled diamondlike three-dimensional protein lattice shown in the picture.

Control of colloidal placement by modulated molecular orientation in nematic cells

Colloids self-assemble into various organized superstructures determined by particle interactions. There is tremendous progress in both the scientific understanding and the applications of self-assemblies of single-type identical particles. Forming superstructures in which the colloidal particles occupy predesigned sites and remain in these sites despite thermal fluctuations represents a major ...

uv Studies of Tetrahedral Bonding in Diamondlike Amorphous Carbon

We report ultraviolet (uv) Raman scattering studies of hydrogen-free, diamondlike amorphous carbon thin films with a wide range of tetrahedral bonding. The uv Raman spectra are shown to provide direct evidence for the presence of sp-bonded C atoms in these materials. The experimental results are found to be in excellent agreement with theoretical predictions and contribute to an improved unders...

Photoconductivity in highly tetrahedral diamondlike amorphous carbon

A photoconductive effect is observed in tetrahedral amorphous carbon (ta-C) or amorphous diamond films with a high proportion of sp3 bonding and a structure analogous to amorphous silicon. The spectral response is shown to peak at around 750400 nm and extend into the near UV region. The maximum photoresponse coincides wit.h the optical absorption edge. The quantum efficiency of 300 nm thick fil...

Tetrahedral calcite crystals facilitate self-assembly at the air-water interface.

Calcite crystals often nucleate and grow in solutions of calcium carbonate, and these crystallites can become trapped at the air water interface, where they form unusual structures. The most common is a fractal structure, which can extend over a large fraction of the interface, and whose origin is understood in terms of the aggregation of the particles. Much more rarely, a different and entirel...

Amelogenin Nanospheres Supra-Molecular Assembly and the Preferential Orientation of Apatite Crystals

Dental enamel is a bio-ceramic formed through a cascade of intra and extra-cellular events among which protein self-assembly is a critical step. Amelogenin selfassembly into nanospheres has been proposed as a key factor in controlling the oriented and elongated growth of enamel crystals. This manuscript is a short review of our recent in vitro study on the process of amelogenin selfassembly int...
