Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

open access: yesAdvanced Materials, EarlyView.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Polynomial progressions in topological fields

open access: yesForum of Mathematics, Sigma
Let $P_1, \ldots , P_m \in \mathbb {K}[\mathrm {y}]$ be polynomials with distinct degrees, no constant terms and coefficients in a general local field $\mathbb {K}$ . We give a quantitative count of the number of polynomial progressions $

Active Diffusion Controlled Dual Stability in Thermoelectrics for Sustainable Heat Harvesting

open access: yesAdvanced Materials, EarlyView.
Introducing a Mg interlayer at the junction simultaneously stabilizes Mg3(Bi,Sb)2 materials and contacts for over 100 days. This dual stabilization derives from suppressing detrimental Mg diffusion and compensating for Mg loss, thereby maintaining an outstanding power density of 0.45 W cm−2 and remarkable conversion efficiency of 8.6% in aged modules ...

Machine Learning‐Enhanced Modular Ionic Skin for Broad‐Spectrum Multimodal Discriminability in Bidirectional Human–Robot Interaction

open access: yesAdvanced Materials, EarlyView.
A machine learning‐enhanced modular ionic skin with broad‐spectrum multimodal sensing is realized through a synergistic material–algorithm optimization strategy. This strategy involves hard‐segment‐modulated 1D/2D/3D‐ionic conductors and a data‐driven decoupling model trained on a curated multi‐stimuli dataset.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Direct Ink Writing of Carbon‐Based Electrofluids for Soft Electrical Component Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
This work explores the manufacturing of Electrofluids (EFs), conductive particle suspensions that flow while maintaining conductivity, for soft electrical components. Using Direct Ink Writing (DIW), patterned EFs achieve enhanced performance, including a 800% sensitivity boost in strain gauges. Through rheological studies, a printability map is created
