Charge Accumulation Characteristics of Nonlinear Conductive SIR Composites under Polarity Reversal Voltage

open access: yesZhongguo dianli, 2020
The HVDC cable accessory is the weak point of the cable system. In order to study the effect of the nonlinear conductivity on the charge accumulation property of SiR cable accessory insulation under polarity reversal voltage, this paper prepared a SiR ...

Influence of volume and surface conductivity on the transient surface charge characteristics of DC‐GIL insulator under thermal–electric coupled fields

open access: yesIET Science, Measurement & Technology, 2022
Here, the transient surface charge distribution of a basin‐type insulator is investigated under thermal–electric coupled fields. Horizontally installed ±200 kV direct current gas‐insulated transmission lines (DC‐GIL) are employed, and a 3D geometric ...

Exploring surface charge dynamics: implications for AFM height measurements in 2D materials

open access: yesBeilstein Journal of Nanotechnology
An often observed artifact in atomic force microscopy investigations of individual monolayer flakes of 2D materials is the inaccurate height derived from topography images, often attributed to capillary or electrostatic forces.

Acoustoelectric Effect of Rayleigh and Sezawa Waves in ZnO/Fused Silica Produced by an Inhomogeneous In-Depth Electrical Conductivity Profile

open access: yesSensors, 2023
The acousto-electric (AE) effect associated with the propagation of Rayleigh and Sezawa surface acoustic waves (SAWs) in ZnO/fused silica was theoretically investigated under the hypothesis that the electrical conductivity of the piezoelectric layer has ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
