Thermoelectric technology generates electricity from waste heat, but one bottleneck for wider use is the performance of thermoelectric materials. Manipulating configurational entropy a material by introducing different atomic species can tune phase composition and extend optimization space. We enhanced figure merit (zT) value to 1.8 at 900 kelvin in an n-type PbSe-based high-entropy formed entropy-driven structural stabilization. The largely distorted lattices this system caused unusual...

A practical and feasible bottom‐up chemistry approach is demonstrated to dramatically enhance thermoelectric properties of the Bi 2 Te 3 matrix by means exotically introducing silver nanoparticles (AgNPs) for constructing composites with hierarchical two‐phased heterostructure. By regulating content AgNPs fine‐tuning architecture nanostructured materials, more heat‐carrying phonons covering broad phonon mean free path distribution range can be scattered. The results show that uniformly...

BRASSINAZOLE RESISTANT 1 (BZR1), the critical regulator of brassinosteroid (BR) response, participates in various BR-mediated developmental processes. However, roles BZR1 stress tolerance are less clear. Here, we found that BZR1-like protein tomato controls BR response and is involved thermotolerance by regulating FERONIA (FER) homologs. The CRISPR-bzr1 mutant showed reduced growth was not responsive to 24-epibrassinolide (EBR) with regard promotion plant growth. Mutation impaired induction...
Abstract Thermoelectric technology converts heat into electricity directly and is a promising source of clean electricity. Commercial thermoelectric modules have relied on Bi 2 Te 3 -based compounds because their unparalleled properties at temperatures associated with low-grade (<550 K). However, the scarcity elemental greatly limits applicability such modules. Here we report performance assembled from -substitute compounds, including p-type MgAgSb n-type Mg (Sb,Bi) , by using simple,...
Abstract The (Bi,Sb) 2 Te 3 (BST) compounds have long been considered as the benchmark of thermoelectric (TE) materials near room temperature especially for refrigeration. However, their unsatisfactory TE performances in wide‐temperature range severely restrict large‐scale applications power generation. Here, using a self‐assembly protocol to deliver homogeneous dispersion 2D inclusion matrix, first evidence is shown that incorporation MXene (Ti C T x ) into BST can simultaneously achieve...
Abstract Although the CoSb 3 -based skutterudite thermoelectric devices have been highly expected for wide uses such as waste heat recovery and space power supply, limited long-term service stability majorly determined by degradation of electrode interface obstructs its applications. Here, we built up an effective criterion screening barrier layer based on combination negative interfacial reaction energy high activation Sb migration through formed layer. Accordingly, predicted niobium a...
