DNA polygonal cavities with tunable shapes and sizes.

چکیده
We developed a new and simple angle control strategy to construct shape- and size-tunable DNA polygonal cavities. A monomer with a controlled slope on one end was used for hierarchical assembly into diverse polygons in a single step. Additionally, by simply moving the position of sticky ends on the monomer, the cavity size can be precisely programmed.

Alignment of high-aspect ratio colloidal gold nanoplatelets in nematic liquid crystals
We study elasticity-mediated alignment of anisotropic gold colloids in liquid crystals. Colloidal gold particles of controlled shapes (spheres, rods, and polygonal platelets) and sizes are prepared using well-established biosynthesis techniques with varying solvent conditions. When introduced into liquid crystalline structured solvents, these gold particles impose tangential or vertical surface...
متن کاملAnalysis of fully developed flow and heat transfer through n-sided polygonal ducts with round corners using the Galerkin weighted residual method
The Galerkin weighted residuals method is extended solve the laminar, fully developed flow and heat transfer of Al2O3-water nanofluid inside polygonal ducts with round corners for the constant heat flux and uniform wall temperature boundary conditions. Using the method, semi-analytical, closed-form solutions are obtained for the friction coefficient and the Nusselt number in terms of the radius...
متن کاملPolygonal tiling of some surfaces containing fullerene molecules
A tiling of a surface is a decomposition of the surface into pieces, i.e. tiles, which cover it without gaps or overlaps. In this paper some special polygonal tiling of sphere, ellipsoid, cylinder, and torus as the most abundant shapes of fullerenes are investigated.
متن کاملLEAF AND STEM ANATOMY OF THE CYPERUS SUBGENUS CYPERUS IN IRAN
The genus Cyperus with five subgenus and 29 species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of 10 species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and ...
متن کاملCreating nanocavities of tunable sizes: hollow helices.
A general strategy for creating nanocavities with tunable sizes based on the folding of unnatural oligomers is presented. The backbones of these oligomers are rigidified by localized, three-center intramolecular hydrogen bonds, which lead to well-defined hollow helical conformations. Changing the curvature of the oligomer backbone leads to the adjustment of the interior cavity size. Helices wit...
