Stretching Single-Stranded DNA on a Surface

Nano Letters, 2001
A sufficiently long strand of DNA bends and balls up, like any other polymer longer than its persistence length. The ability to stretch a DNA molecule lengthwise on a substrate has garnered a great deal of attention in the past several years. There has been notable success in stretching double-stranded DNA (dsDNA), but it is more difficult to stretch ...

Reduce the stretch in surface flattening by finding cutting paths to the surface boundary

Computer-Aided Design, 2004
This paper presents a method for finding cutting paths on a 3D triangular mesh surface to reduce the stretch in the flattened surface. The cutting paths link the surface boundary and the nodes where the Gaussian curvature is high, and their total length is minimized.

The Flow in a Viscous Fluid over an Unsteady Stretching Surface

2015 17th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (SYNASC), 2015
The continuity and momentum equations are reduced to ODE using the similarity transformations. The obtained equation is solved approximately by means of the Optimal Homotopy Asymptotic Method (OHAM). Some examples are given and the results obtained reveal that our procedure is effective, very accurate and easy to use.

Effects of normal stress on aorta surface stretching and permeability

Journal of Biomechanics, 1981
Abstract Homogeneous segments of the ventral portion of pig thoracic aorta were incubated in specially constructed chambers to assess the effects of fluid pressure, in the absence of shearing stress, on surface stretching, and permeability to albumin.

Localization and stretching of polymer chains at the junction of two surfaces

The Journal of Chemical Physics, 2014
We present a molecular dynamics study on the stretching of a linear polymer chain that is adsorbed at the junction of two intersecting flat surfaces of varying alignments. We observe a transition from a two-dimensional to one-dimensional (1D) structure of the adsorbed polymer when the alignment, i.e., the angle between the two surfaces that form a ...

Stretching Cell Surface Macromolecules by Atomic Force Microscopy

Langmuir, 2001
We report the first quantitative measurement of macromolecular stretching at the surface of living cells using combined atomic force microscopy imaging and force spectroscopy. The surface of dormant spores of Aspergillus oryzae was covered with a layer of crystalline-like nanostructures (rodlets) and showed no/weak adhesion forces.

FLUID FILM SPRAYED ON A STRETCHING SURFACE

Chemical Engineering Communications, 1991
A liquid film, due to spraying, is deposited on a stretching surface. The physical problem is governed by a nondimensional parameter α, representing the relative importance of spraying rate to stretching rate. After a similarity transform, the Navier-Stokes equations reduce to a nonlinear ordinary differential equation which is solved by perturbation ...

Heat transfer from a stretching surface

International Journal of Heat and Mass Transfer, 1993
The work deals with heat transfer from an arbitrarily stretching surface \(U\sim x^ m\) for investigating the effects of non-uniform surface temperature. Several closed form solutions for specific values of \(m\) including their numerical solutions are presented in this technical note.
