The ubiquitous biomacromolecule DNA has an axial rigidity persistence length of ~50 nm, driven by its elegant double helical structure. While double and multiple helix structures appear widely in nature, only rarely are these found in synthetic non-chiral macromolecules. Here we report a double helical conformation in the densely charged...

Sand‐Mud Tidal Flat Morphodynamics Influenced by Alongshore Tidal Currents

Wang, Yunwei (author), Wang, Yaping (author), Yu, Qian (author), Du, Zhiyun (author), Wang, Zhengbing (author), Gao, Shu (author)

Tidal flats, where significant land‐ocean interactions take place, are often abstracted as a cross‐shore bed profile with sediment zonation from the lower sand flat to the upper mud flat. However, in addition to cross‐shore tidal currents, the impact of the alongshore components on cross‐shore sediment transport, morphological evolution, and...

The relationship between inundation duration and Spartina alterniflora growth along the Jiangsu coast, China

Li, R. (author), Yu, Qian (author), Wang, Yunwei (author), Wang, Zhengbing (author), Gao, Shu (author), Flemming, Burg (author)

The above-ground biomass of Spartina alterniflora salt marsh meadows is influenced by numerous interacting factors, among them elevation, tidal range and inundation duration. Bio-geomorphological models make use of either linear or quadratic equations, but it is important to be aware that the variables are area specific and hence not generic. In...
