  The Piecewise Diffusion of the Silicon Dimer
However, the distribution of dimers occupying the two types of sites upon formation is kinetically determined: one third form on rows and two thirds form in troughs [6].
Because of the strong anisotropy of the Si(001) reconstructed surface, diffusion is strongly one dimensional.
The dimer dissociates as one atom moves ahead, and the two atoms move up and down the trough independently until they meet again and reform the dimer in a new location.

 IFS Attractors: dimers (2D)
Of all rep-tiles the dimers are the easiest to enumerate, as there are just 4 independent parameters, the angles by which each element is rotated with respect to the whole figure, and whether each element is directly or inversely similar to the whole figure.
Even with the restricted phase space of the set of dimers an exhaustive search would be time consuming, so investigation of the set of dimers has to be based on theoretical and heuristic grounds.
Of the 12 distinct figures, 8 are amongst the 10 figures identified as dimers.

 Dimer   (Site not responding. Last check: 2007-10-20)
Its more common usage refers to dimers as certain types of sugar: sucrose, for example, is a dimer of a glucose molecule and a fructose molecule.
The dimerization of identical subunits is called homodimerization, the dimerization of different subunits or unrelated monomers is called heterodimerization.
Most dimers in biochemistry are not connected by covalent bonds with the exception of disulfide bridges.

This suggests that as the dimer moves through the lattice it produces in front of it a large `bow wave' of lattice compression.
The vibrational modes of the asymmetric dimer are given in Table 6.4.
A possible alternative dimer model would be two O atoms in these positions, which is shown schematically in Figure 6.6.

 Dimer Placement Tool
Here, we investigate this proposed new class of horizontal dimer placement tools by focusing on the six particular tool tip structures shown in Figure 4, evaluating both their stability and the strength of their bonding to the CC dimer.
The DCB6-X family of dimer placement tools, for X = Si, Ge, Sn and Pb, should be stable in vacuum when used at room temperature, and possibly at significantly higher temperatures.
The CC dimer is bound to these tools by progressively weaker bonds, moving from Si to Pb, facilitating release of the CC dimer from the tool and its attachment to a growing molecular structure.

A, a schematic of the pull-down assay used to measure TBP dimer dissociation kinetics.
In viewing this schematic, it is important to recognize that dimer stability is driven by a broad, largely hydrophobic interface, which is not illustrated here.
This is a predicted outcome of enhanced dimer stability.

 Theoretical analysis of a carbon-carbon dimer placement tool for diamond mechanosynthesis
The function of a dimer placement tool is to position the dimer, then bond the dimer to a precisely chosen location on a growing molecular structure, and finally to withdraw the tool – leaving the dimer behind on the growing structure.
To achieve this, the dimer is required to be (1) bonded relatively weakly to the tool and (2) highly strained and thus highly reactive so it will strongly bond to the growing molecular structures to which it is added.
For the proposed tools that are modeled computationally here, the requirements are met by bonding the dimer to two supporting atoms selected from the elements silicon, germanium, tin or lead (which form progressively weaker bonds to carbon).

 Tracking study of dimer dissociation and step edge interactions
The population of dimers on the silicon surface depends on the activation energy for dimer dissociation.
By applying the tracking technique to studies of Si dimer diffusion on the Si(001)-2 × 1 surface, we have resolved individual diffusive events.
As with our application to Si dimers a Si surface, the tracking technique promises to provide time resolutions of single feature processes that are unattainable by current conventional STM techniques.

 FGF 9 Dimer Kinemages
FGF 9 is unique in that in solution it forms a dimer (Kinemage 2 and Kinemage 3) that occludes areas of the molecule that in other FGF species are associated with heparin and receptor binding.
An overlay of the individual chains of the unit cell (Kinemage 4) shows that the core of the FGF 9 molecule is not altered upon dimerization.
These are shown in Kinemage 9 Since these residues are buried within the dimer conformation, it is necessary that the dimer quaternary structure be broken for the monomer to approach the ligand binding domain of a FGF receptor.

 Structure of Ammonia Dimer   (Site not responding. Last check: 2007-10-20)
In water dimer there is one hydrogen bond and it is rather "linear", that is, the acceptor atom and the H-O bond of the the H-bond donor are nearly colinear.
In bend hydrogen bonds the acceptor and the H-X bond are not colinear.
While each bend interaction is not as good as a linear interaction, two bend interactions are better than one linear interaction in the case of ammonia.

Firing only enough energy to disrupt one dimer with each laser pulse, researchers performed the experiments until as many as 500,000 dissociations had been observed.
The dimer fragments were analyzed by a tool developed at Sandia/California called a time-resolved, coincidence-imaging spectrometer.
The measurements from the molecular perspective were done at Sandia, with complementary work to measure dimer intermediate state lifetimes achieved in Albert Stolow's group at the Steacie Institute for Molecular Sciences, at the National Research Council of Canada.
