Stretching single molecular DNA by temperature gradient
Applied Physics Letters, 2007The authors present a method to control the conformation of DNA by using temperature gradient. The conformations of one end tethered and two ends tethered DNA are measured in different temperature gradients up to 3K∕μm. The results show that temperature gradient can exert force on a single DNA and create internal tension within it. The magnitude of the

Stretching Temperature Dependency of Fibrillation Process in Isotactic Polypropylene
The Journal of Physical Chemistry B, 2017Isotactic polypropylene samples annealed at three temperatures were used to explore their fibrillation behaviors during tensile deformation at elevated temperatures via in situ synchrotron small and wide-angle X-ray scattering techniques. Fibrillation denotes the transition of the isotropic spherulitic morphology into a highly oriented one during ...

Accumulation and Stretching of DNA Molecules in Temperature-Induced Concentration Gradients
The Journal of Physical Chemistry B, 2023Temperature fields provide a noninvasive approach for manipulating individual macromolecules in solution. Utilizing thermophoresis and other secondary effects resulting from the inhomogeneous distribution of crowding agents, one may gain valuable insights into the interactions of molecular mixtures.

ABSTRACTCrosslinked polyethylene films were prepared and stretched at different temperatures (below and above melting temperature). The stretching temperature exhibited pronounced effects on the structure and puncture resistance of the films. Combining the results of differential scanning calorimetry, 1D X‐ray diffraction, 2D X‐ray diffraction, and ...

AbstractTo better understand the two synchronous processes of lamella orientation and crystal transition of iPB‐1 during stretching, the stretching‐induced changes in the crystal structure of iPB‐1 were investigated at different temperatures (room temperature, 65, and 85°C) and stretching speeds (5, 10, and 20 μm/s).
