Performance Enhancement of Thermoelectric Generators Integrated With Phase Change Materials: A Transient Numerical Analysis

Energy Storage, Volume 8, Issue 6, September 2026.
ABSTRACT This study presents a numerical analysis of thermoelectric generators (TEGs) integrated with a heat sink and phase change materials (PCMs), focusing on their combined impact on thermal management and power output. The module, comprising a bismuth telluride (Bi2Te3)‐based TEG coupled with a paraffin wax PCM, was evaluated using finite element ...

Nonequilibrium evaporation enables carrier polarity control in Bi‐Te thin films

InfoScience, Volume 3, Issue 3, September 2026.
Controlling carrier polarity in semiconductors is important for developing advanced electronics but is usually achieved through doping or composition engineering. Here, we demonstrate that nonequilibrium evaporation can naturally reshape Bi–Te thin films from a Te‐rich p‐type conducting phase to a Bi2Te3‐rich n‐type phase during growth.

Transition Metal Chalcogenides: Perspectives on Their Applications for Nitrate Reduction

ChemistryOpen, Volume 15, Issue 9, September 2026.
This review paper reports the syntheses, properties, and applications of TMCs for electrochemical reduction of nitrate to ammonia. Various studies revealed that the conversion of nitrate to ammonia is principally the electrocatalytic hydrogenation of nitrate and the rate and yield of ammonia is competitively challenged by hydrogen evolution reaction ...

Mechanically Robust Dicing‐Free Thermoelectric Module Fabrication Using Anion‐Cation co‐Doped Bismuth Tellurides

Small, Volume 22, Issue 51, 11 September 2026.
NaCl co‐doping effectively enhances the thermoelectric performance of p‐type Bi–Sb–Te (BST) alloys through simultaneous Na+ substitution at Sb sites and Cl− substitution at Te sites, inducing local lattice distortion and defect engineering. At low doping levels, carrier transport is optimized by tuning carrier concentration and suppressing antisite ...
