Conformations and diffusion of flexibly linked colloidal chains

The Description of Conformations of Polynucleotide Chains

Conformations of single polymer chains on surfaces

Frontali et al. [137] showed in 1979 that it is possible to characterize the structure of polymers by analyzing high resolution microscopy images. The authors adsorbed DNA molecules onto mica and imaged them using electron microscopy. From the vectorized contours of single chains, they were able to determine both contour and persistence lengths so that the polymers were fully described in the f...

Growth kinetics of colloidal chains and labyrinths.

Particles interacting by a combination of isotropic short-range attraction and long-range repulsion have been shown to form complex phases despite the apparent simplicity of the interparticle potential. Using computer simulations we study the behavior of two-dimensional systems of colloids with such an interaction, focusing on how area fraction and repulsion range at fixed repulsion gradient ma...

Homo- and Hetero-bimetallic Flexibly Linked Dinuclear Salphen Complexes

A modification of the previously developed synthetic approach towards dinuclear flexibly linked salphen complexes is successfully utilized for the preparation of heterodinuclear salphen dimers. A dinuclear salphen species with Pd(II) and Cr(III) centers bears a stronger structural resemblance to the related bis-Cr(III) compound than the corresponding mononuclear Cr(III) salphen complex. Therefo...

Solubility and molecular conformations of n-alkane chains in water.

We employ molecular dynamics simulations to study the solubility and molecular conformations of n-alkane chains in water. We find nearly exponential decrease in solubility with carbon number up to n-eicosane (C(20)), and excellent agreement with experiment up to n-dodecane (C(12)). We detect no sharp break in the dependence of the solubility upon carbon number. A free energy landscape analysis ...
