Design and self-assembly of two-dimensional DNA crystals
Article Abstract:
The mathematical theory of tiling has been used as a basis for a new approach to two-dimensional crystal design in which three 2-D lattices with two distinct topologies have been assembled from double-crossover (DX) molecules. The periodic blocks used in this research are made up of either two or four individual DX units. It has been possible to indicate the potential of using DNA to form self-assembly periodic nanostructures. The two-dimensional lattices demonstrated in this research could be extended into three dimensions.

Weak surface anchoring of liquid crystals
Article Abstract:
Current nematic liquid-crystal (LC) displays depend on voltage induced reorientation of the direction in the bulk of the LC layer. Weak anchoring of the LC can result in lower operating voltages and improved steepness, but it is difficult to achieve weak anchoring in practice. An approach using the addition of small amounts of oligomeric molecules to the LC is reported, resulting in small zenithal and azimuthal anchoring energies.

Determination of relative growth rates of natural quartz crystals
Article Abstract:
It has been possible to measure the size, shape and relative growth rate of each of the faces of a single, gem-quality quartz crystal. Hydrogen-bearing impurities can monitor the growth rate of advancing crystal faces.
