Lead sulfide (PbS) is a promising mid-temperature thermoelectric material; however, its performance is constrained by the difficulty of simultaneously optimizing electrical transport and suppressing lattice thermal conductivity. Herein, a Bi2Se3 incorporation strategy is developed to synergistically regulate carrier an...
Lattice strain engineering can regulate the electronic structure of electrocatalysts, but stabilizing distorted metastable phases remains challenging. Here, we report an N,N-dimethylformamide-assisted strategy for synthesizing metastable hexagonal close-packed (HCP) Ni nanoparticles with local lattice-spacing deviation...

SnTe has emerged as a promising lead-free thermoelectric material, yet its practical performance is limited by excessive hole concentration arising from Sn vacancies, low Seebeck coefficient, and excessive thermal conductivity. Herein, we enhance the thermoelectric properties of SnTe by alloying with colloidally synthe...

Polymer dielectrics are vital for high-power electronics, yet their high-temperature application is fundamentally constrained by the inherent trade-offs among thermal stability, polarization retention, and conduction loss. Here, we mitigate these limitations by integrating high-entropy nanofillers with a preferentially...
