Wireless Acousto‐Piezoelectric Conduit with Aligned Nanofibers for Neural Regeneration

Advanced Materials, EarlyView.
An ultrasound‐driven, highly aligned piezoelectric nanofiber‐based nerve guidance conduit (APNF‐NGC) designed for effective peripheral nerve repair has been demonstrated in this study. Featuring aligned topology, cell‐adhesive surfaces, and an axial electric field, the APNF‐NGC collectively promotes significant nerve regeneration.

Relative permittivity in stern and diffuse layers.

Acta chimica Slovenica, 2014
Stern layer and outer Helmholtz plane (i.e. the distance of closest approach) are considered within electric double layer models, where the orientational ordering of water dipoles is explicitly taken into account. It is shown that permittivity of the Stern layer is not independent of the surface charge density as it is frequently assumed in different ...

Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides

Advanced Materials, EarlyView.
This work introduces an approach to defect‐mediated symmetry breaking and built‐in polarization in nominally centrosymmetric defective oxides, Gd‐doped CeO2‐δ films, by controlling macroscopic charge asymmetry. Electric field‐driven asymmetric redistribution of oxygen vacancies induces a switchable, stable polarization, leading to a notable, persistent

Using the Probability Density Function-Based Channel-Combination Bloch–Siegert Method Realizes Permittivity Imaging at 3T

Bioengineering
Magnetic resonance electrical properties tomography (MR EPT) can retrieve permittivity from the B1+ magnitude. However, the accuracy of the permittivity measurement using MR EPT is still not ideal due to the low signal-to-noise ratio (SNR) of B1 ...

Two‐Stage Bipolaron Formation in Molecularly Doped Conjugated Polymers

Advanced Materials, EarlyView.
This work investigates bipolaron formation in 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ)‐doped conjugated polymer P(g32T‐T) films with glycol sidechains at two stages of both low and high doping levels. At the early stage, bipolarons mainly form from double doping, enhancing structural ordering, and carrier transport.

Constraining snow water equivalent of wet snowpacks in Southeast Alaska

Annals of Glaciology
Quantifying snow water equivalent (SWE) with ground-penetrating radar (GPR) in a warming climate is complicated by the incidence and variability of liquid water in snow.

Microstructure Optimization via Grain‐Boundary Segregation to Enhance DC Bias Dielectric Performance of BaTiO3 Multilayer Ceramic Capacitors

Advanced Materials, EarlyView.
By tuning grain size through nanoscale grain‐boundary segregation of single‐element additives, high‐performance BaTiO₃‐based multilayer ceramic capacitors (MLCCs) exhibit exceptionally low dielectric loss over a wide frequency range and excellent thermal stability.
