Image showing 8530 adatoms and substrate atoms Maura E. Monville, Zhenyu Zhang and George H.Gilmer, Monte Carlo simulation of clustering effects on surfaces, Oak Ridge National Laboratory and Lawrence Livermore National Laboratory, USA. This image shows 1030 adatoms over 7500 substrate atoms, after 20,000 simulation cycles. Size: 92,832 bytes.

Image showing BCC, FCC and HCP tetrahedral and octrahedral interstices BCC, FCC and HCP structural cells (yellow atoms), showing all the tetrahedral and octahedral interstices available, as described by the largest atoms that can occupy those sites without causing distortion (green atoms). Atoms and Cells are all represented on the same scale, structural (yellow) atoms have all a radius equal to 1.0, and cell parameters were chosen so structural atoms just touch the first neighbours. A few structural atoms were removed to improve visibility. Size: 46,189 bytes.

Image showing Help->Config and Help->Start dialogs The Help->Config dialog, to configure documentation source (local or remote, HTTP or FTP) and carrying agent (Gamgi or a Browser), over the Help->Start dialog, saluting newbies (using the same green and yellow default colors as Emacs on Red Hat 9.0). Help documentation is taken from XML files, except Help->Start which is directly built-in (so it is always available, even if documentation paths are misconfigured). Size: 49,379 bytes.

Image showing atomic deposition by Monte Carlo simulation Maura E. Monville, Zhenyu Zhang and George H.Gilmer, Oak Ridge National Laboratory and Lawrence Livermore National Laboratory, USA. Atomic deposition over a substrate lattice, by Monte Carlo simulation, as a result of the combined effect of Laser Steering and Temperature Gradient. Both effects stem from the interference pattern (standing wave) formed by two counter-propagating waves (the two laser beams E-fields respectively). The goal is to prove that by proper tuning of the Laser experiment-controllable parameters the two effects can be made work together in a constructive way so enhancing the resolution of nano-scale atomic patterns in cases of deposition of metal on metal. Size: 161,387 bytes.

Image showing silica clusters represented with different styles Some of the silica clusters acting as building units in sol-gel processes, zeolite catalysis and in the chemistry of silica in solution, shown with different styles. The dimer Si2O(OH)6, represented in wired mode, was built on a different, transparent, layer, so it is not affected by the diffuse light used to illuminate the other clusters. The monomer Si(OH)4, at the bottom right corner, was represented using the tabulated covalent radius for Si, O, H. The bottom menus were switched off, to emphasize the image. Size: 37,945 bytes.

Image showing the Voronoi tesselation of DNA, with outer boundary planes Voronoi tesselation of the DNA double-helix (698 atoms), limited by six outer boundary planes. Silicons are yellow, Oxygens are red, Nitrogens are blue, Carbons are green, Phosporous are orange and Hydrogens are white. Size: 30,099 bytes.

Image showing the Voronoi tesselation of DNA, with periodoc boundary conditions Voronoi tesselation of the DNA double-helix (698 atoms), using periodic boundary conditions, with the extended convention (the minimum convention, usually applied in Molecular Dynamics, cannot be used in Voronoi tesselation). Silicons are yellow, Oxygens are red, Nitrogens are blue, Carbons are green, Phosporous are orange and Hydrogens are white. Size: 34,100 bytes.
