Diatomics: Toward Diatom Functional Genomics
Journal of Nanoscience and Nanotechnology, 2005For diatom biologists one of the most interesting research areas over the next years will be in linking mathematical models for pattern formation with information derived from molecular genetic, biochemical, and physiological studies. A major goal of this research is to exploit diatom proficiency in biogenic silica formation to develop strategies for ...

Journal of Nanoscience and Nanotechnology, 2005
The development of low cost hierarchical porous materials based upon the zeolitisation of diatomaceous earth for fluid waste benification is described. Two preparative approaches invole: first, using the diatom as a support for zeolite nanocrystals; second, direct pseudomorphic transformation of the diatom into a zeolite.

Notes for a Short Course: Studies in Geology, 1987
Diatoms are unicellular golden brown algae, that are characterized by an external box-like skeleton (or frustule) of opaline silica. Diatom frustules are commonly very intricate and varied, and the patterns and types of ornamentation of the frustule form the basis of nearly all diatom taxonomy. The size of diatom frustules ranges from less than one μm (

Rotational transfer in diatom–diatom collisions
Chemical Physics Letters, 2001Abstract We present a kinematic hard ellipsoid model of rotational transfer in diatom–diatom collisions. The model extends the principles of the angular momentum (AM) model of rotational transfer (RT) developed for atom–diatom collisions and the hard ellipsoid model of the repulsive potential.

Bioinspiration & Biomimetics, 2013
The diatoms are ubiquitous, exist in large numbers and show a great diversity of features on their porous silica structures. Therefore, they inspire the fabrication of nanostructured templates for nanoimprint processes (NIL), where large structured areas with nanometer precision are required.

Diatom-diatom reactive scattering in hypercylindrical coordinates
International Journal of Quantum Chemistry, 2009We present a combination of hyperspherical and cylindrical coordinates to describe diatom–diatom reactions in which one diatom bond is nonreactive. This hybrid system of coordinates is termed hypercylindrical. It naturally leads to a description of the reaction as an atom–diatom reaction embedded within a larger polyatomic framework.

Semiclassical theory for diatom-diatom collisions
Chemical Physics Letters, 1983Abstract A semiclassical approach to diatom-diatom collisions is presented. The method involves a classical treatment of the translational and rotational motion of both molecules. The vibrational degrees of freedom are quantized using a Morse oscillator approximation. The method is used to evaluate the accuracy of previous calculations based upon the
