A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

Smart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...

Synthesis of Patchy Particles at Phase Boundaries

Small Methods, EarlyView.
The various strategies employed for synthesizing complex multifunctional patchy particles are reviewed, with, as a guideline, the type of phase boundary (solid‐gas, liquid‐gas, solid‐liquid, and liquid‐liquid), that serves as the crucial ingredient for symmetry breaking.

A New Approach for Optimizing a Bipolar Charge Transport Model for Dielectric Materials: Theoretical Framework

IEEE Transactions on Dielectrics and Electrical Insulation, 2021
A bipolar charge transport model with two levels of traps (shallow and deep traps) is employed to describe and investigate the dynamic behavior of the space charge in low-density polyethylene (LDPE). This kind of model requires some initial experimental conditions alongside a set of parameters.

Simulation of space charge behavior in LDPE with a modified of bipolar charge transport model

Proceedings of 2014 International Symposium on Electrical Insulating Materials, 2014
In this paper, an simply ion charge transport model is proposed, compared with bipolar charge transport model. It consists of ion generation by field assisted dissociation of impurities, transport, trapping and recombination in polymer. To simplify the model, it is assumed that only one type of impurity existing in polymer.

Charge transport properties of insulators revealed by surface potential decay experiment and bipolar charge transport model with genetic algorithm

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
To evaluate spacecraft charging level and predict surface and internal electrostatic discharging (ESD) probability, it is important to know the charge transport properties of high insulation materials, such as epoxy resin/glass composition (FR4), Teflon and polyimide. In present work, the charge transport properties of the space insulators are revealed

A model for bipolar charge transport, trapping and recombination in degassed crosslinked polyethene

Journal of Physics D: Applied Physics, 1994
Measurements of the space charge density across the width of a plane parallel sample of degassed crosslinked polyethene (XLPE) have been made recently. Repeated at intervals throughout a period of applied high voltage, these measurements provide data on the dynamics of charge injection and space charge development in the sample under the influence of a
