Rational design of large anomalous Nernst effect in Dirac semimetals

npj Computational Materials, 2023
Anomalous Nernst effect generates a transverse voltage perpendicular to the temperature gradient. It has several advantages compared with the longitudinal thermoelectricity for energy conversion, such as decoupling of electronic and thermal transports ...

Finite-temperature violation of the anomalous transverse Wiedemann-Franz law

, 2019
The Wiedemann-Franz (WF) law links the ratio of electronic charge and heat conductivity to fundamental constants. It has been tested in numerous solids, but the extent of its relevance to the anomalous transverse transport, which represents the ...

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...

Observation of anomalously large Nernst effects in conducting polymers

Nature Communications
As a fundamental thermoelectric phenomenon in many solid-state materials, the Nernst effect has yet to be observed in conducting polymers. This knowledge could provide important insight into their elusive mechanism, which are crucial for flexible optoelectronic and thermoelectric applications.

Modeling Zero‐Gap Saltwater Electrolysis With Advective Flow Through a Thin‐Film Composite Membrane

ChemSusChem, Volume 19, Issue 3, February 2026.
During saltwater electrolysis with a thin‐film composite membrane, ion and water transport are coupled. The direction of water flux follows that of the dominant salt ion carrying charge. When Na+ transport from the anode to the cathode is dominant, fluid flow occurs in the same direction.

Evaluation of Process Parameters for Integrated CO2 Electrolysis to Produce Ethylene

ChemistryOpen, Volume 15, Issue 2, February 2026.
This work systematically explores how flow rate, pressure, and temperature influence ethylene selectivity in integrated CO2 electrolysis with a potassium carbonate absorbent. Findings reveal that higher catholyte flow rates improves Faraday efficiency for ethylene by overcoming mass transport barriers, while increased pressure or temperature does not ...

The Nernst effect in high-$T_c$ superconductors

, 2005
The observation of a large Nernst signal $e_N$ in an extended region above the critical temperature $T_c$ in hole-doped cuprates provides evidence that vortex excitations survive above $T_c$.

Ultrahigh anomalous Nernst thermopower and thermal Hall angle in YbMnBi2

Communications Materials
Thermoelectrics (TEs) are solid-state devices that can realize heat-electricity conversion. Transverse TEs require materials with a large Nernst effect, which typically requires a strong applied magnetic field.
