Thermoelectric Property Mapping for High‐Performance Integrated MgAgSb‐MgCuSb System

Advanced Science, Volume 13, Issue 17, 23 March 2026.
From the property mapping of the MgAgSb–MgCuSb system, both thermoelectric materials and corresponding interface materials are optimized: Ag‐rich compositions provide higher PF and zT, whereas Cu‐rich side yields superior transport properties and low contact resistance.

Stepwise Optimization of Thermoelectric Performance in Cu3SbSe4‐Based Compounds via Alloying and Hierarchical Structuring

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
Under the stepwise optimization strategy, (Sn, Te) co‐alloying functions as the primary initiative to enhance the power factor (PF), while the subsequent incorporation of AgCuTe operates as a synergistic maneuver to suppress lattice thermal conductivity (κlat), thereby concomitantly boosting the dimensionless figure of merit (ZT).

Is the Archimedes principle a law of nature? Discussions in an ‘extended teacher room’

Physics Education, 2020
Abstract Is a suction cup at the bottom of a bathtub subject to an upward force from the surrounding water, even if there is no water under it? A student question, posted in a teacher facebook group on a Monday morning, led to a discussion involving 21 comments with 225 replies offered by 16 teachers during the next few days, including ...

Linking Density and Nanoscale Crystallinity to Hydration in Nafion PEMFC Membranes: Insights From Experiment and Molecular Dynamics Simulations

Small Structures, Volume 7, Issue 3, March 2026.
Molecular dynamics and experimental analysis show that higher crystallinity in Nafion enhances molecular packing, thereby increasing effective density. A proposed model bridges experimental and molecular‐scale observations by quantitatively linking water uptake to density variations, offering a predictive framework for optimising hydration and ...
