Electron Lattice Dynamics as a Method to Study Charge Transport in Conjugated

, 2011
As functional elements in opto-electronic devices approach the singlemolecule limit, conducting organic molecular wires are the appropriateinterconnects that enable transport of charges and charge-like particles such as excitons within the device ...

Pt‐Regulated Dynamic Cu(0) Regeneration in CuPt Alloy Enables High‐Efficiency Self‐Driven Formaldehyde Fuel Cells for Potassium Formate Production

Advanced Science, EarlyView.
In this work, a Cu30PtX/CF anode material was synthesized to effectively catalyze the electrocatalytic formaldehyde oxidation, and thereby assembled a fuel cell that offered a high open‐circuit potential of 0.94 V and a power density of 34.3 mW cm−2. This work realizes the co‐generation of electrical energy and high‐value‐added chemicals with nearly ...

Sandwich‐Structured Aramid Composite Papers with Heterogeneous Dielectric Layers for Integrated Corona Resistance and Thermal Conductivity

Advanced Science, EarlyView.
A sandwich‐structured aramid composite paper was designed to integrate high corona resistance and thermal conductivity. The fluorinated graphene/aramid surface layers effectively dissipate space charges to suppress corona discharge. Meanwhile, the boron nitride nanotube/aramid core layer constructs continuous heat‐conduction pathways.

Linkage Engineering Boosts Battery Performance of Two‐Electron Phenothiazine‐Based Polyamide Cathodes

Advanced Science, EarlyView.
Three phenothiazine‐based polyamides featuring gradually strengthened electron‐withdrawing linkers are developed as high‐voltage cathodes for lithium‐organic batteries. The linker motif serves not only as a structural bridge to suppress solubility, but also as a functional design element that governs optoelectronic properties and electron/ion transport

Unraveling the Effects of Depolarization in Ultrathin Barium Titanate

Advanced Science, EarlyView.
This article employs synchrotron‐based spectroscopy, time‐resolved electrical measurements, and phase‐field simulations to establish reverse‐domain formation as the mechanism of polarization loss in ultrathin BaTiO3${\rm BaTiO}_3$ films as a critical obstacle to low‐voltage ferroelectric devices.

Hardware Acceleration of Stochastic Neural Networks Enabled by Bit‐Cell Level Co‐Design of Magnetic Tunnel Junctions

Advanced Science, EarlyView.
An MTJ‐based probabilistic processing‐in‐memory architecture unites nonvolatile storage, local entropy generation, and stochastic computation within each memory cell. Stored multi‐bit weights are converted directly into programmable stochastic bitstreams, enabling neural‐network inference, adaptive Ising optimization, and uncertainty‐aware Bayesian ...

Excellent Thermoelectric Performance Realized in SnSe Materials via Chemical Bond Tailoring Using GeTe as Molecule Scissors

Advanced Science, EarlyView.
The GeTe acting as “molecule scissors” can tailor chemical bond, the breaking of Ag‐Se bonds and the formation of Ge‐Se bonds occur in the A‐SnSe matrix, along with the formation of Ag2Se precipitates. This process helps to optimize the thermoelectric properties, and also improves its mechanical properties to a certain extent.
