Direct evidence for electrostriction‐enhanced piezoelectricity in poly(vinylidene fluoride‐co‐trifluoroethylene) random copolymers

open access: yesResponsive Materials, EarlyView.
Direct experimental evidence for electrostriction‐enhanced piezoelectricity is obtained for a quenched‐stretched‐annealed‐poled P(VDF‐TrFE) 52/48 mol.% random copolymer using time‐resolved small‐angle X‐ray scattering and wide‐angle X‐ray diffraction. Upon stretching up to 6% strain, the crystallinity (xc) increases 10% at the expense of the contents ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Geomorphic Responses to Post‐Grazing Recovery and Stream Restoration in Semiarid Grassland Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Semiarid grassland streams are sensitive to land use, climate, extreme discharges, and internal geomorphic thresholds that drive episodic erosion. Rooted in a process‐based philosophy and commonly applied to historically wood‐rich, beaver‐modified systems, low‐tech process‐based restoration using structures is increasingly being extended to ...
