Modulation of the Nernst Thermoelectrics by Regulating the Anomalous Hall and Nernst Angles

Advanced Science
The large anomalous Nernst effect in magnetic Weyl semimetals is one of the most intriguing transport phenomena, which draws significant attention for its potential applications in topological thermoelectrics.

Kinetic modeling of Nernst effect in magnetized hohlraums [PDF]

Physical Review E, 2016
We present nanosecond time-scale Vlasov-Fokker-Planck-Maxwell modeling of magnetized plasma transport and dynamics in a hohlraum with an applied external magnetic field, under conditions similar to recent experiments. Self-consistent modeling of the kinetic electron momentum equation allows for a complete treatment of the heat flow equation and Ohm's ...

Magnetic‐Field Modulation of Charge Transport in Non‐Fullerene Semiconductors for Enhanced Hydrogen Evolution

Advanced Materials Interfaces, EarlyView.
ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...

Large magneto-thermoelectric effect on the verge of metal–insulator and topological transitionsin pyrochlore iridates

APL Materials, 2022
We investigate the Seebeck and Nernst effects of pyrochlore iridium oxides (Nd1−xPrx)2Ir2O7 across the thermally induced and magnetic field-induced metal–insulator and topological transitions.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

A Pollen‐Enhanced Bionic Mechanoreceptor Induced by Asymmetric Ionic Convection in Hydrogel for Sensory‐Augmented Prostheses

Advanced Science, EarlyView.
This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...

Topological materials for high performance transverse thermoelectrics

Next Energy
Transverse thermoelectrics based on Nernst-Ettingshausen effect have been widely investigated in the 20th century. Old results of transverse thermoelectrics have shown low performances and usually require large magnetic fields. In recent years, the surge
