Le regole del gioco: Primo incontro con l'ingegneria strategica
Cu particles decorated carbon composite
microspheres (CCMs) with
a unique sesame ball structure have been prepared by combining the
mass-producible spray drying technique with calcinations. The conventional
cuprammonium cellulose complex solution obtained by dissolving cellulose
in a cuprammonia solution has been applied as raw materials for the
preparation of Cu(NH<sub>3</sub>)<sub>4</sub><sup>2+</sup>/cellulose
complex microspheres via a spray drying process. The resulted Cu(NH<sub>3</sub>)<sub>4</sub><sup>2+</sup>/cellulose complex microspheres
are then transformed into the Cu particles homogeneously decorated
porous carbon spheres <i>in situ</i> by calcinations at
450 or 550 °C. The coordination effect between the Cu(NH<sub>3</sub>)<sub>4</sub><sup>2+</sup> species and the hydroxyl groups
of the cellulose macromolecules has been exploited for directing the
dispersion of the Cu particles in the resultant composite CCMs. The
antimicrobial effects of the CCMs are evaluated by determining the
minimum growth inhibitory concentrations using Staphylococcus
aureus and Escherichia coli as representatives, respectively. The CCMs show high efficiency
catalytic properties to the conversion of 4-nitrophenol to 4-aminophenol
using NaBH<sub>4</sub> as a reductant in a mild condition. The recyclability
and stability of the CCM catalysts have also been studied

The redundant point whose valence is four.
<p>The black point is redundant point. The red points are 1-ring neighborhoods of the black point. The figure shows two cases that the black point is near two different diagonals.</p

SMOPT
The procedure utilizes an algorithm to remove redundant points having three or four valences and another algorithm to smooth the mesh using a modified version of Laplacian method without causing intersecting triangles
Initial mesh and improved meshes for an AChE monomer.
<p>(a) is the initial mesh, (b) is the improved mesh by SMOPT and (c) is the improved mesh by ISO2mesh. The left sub-figure in (c) shows an example of self-intersection in the mesh improved by ISO2mesh. The red triangle intersect with the yellow triangle. The left sub-figure in (b) shows the same region as the sub-figure in (c) and there is no intersection.</p
The black point is considered as the redundant point when it has a valence of three and is almost on the plane formed by its 1-ring neighborhoods in red color.
