Abstract The development of new materials and their compositional microstructural optimization are essential in regard to next-generation technologies such as clean energy environmental sustainability. However, discovery have been a frustratingly slow process. Edisonian trial-and-error process is time consuming resource inefficient, particularly when contrasted with vast design spaces 1 . Whereas traditional combinatorial deposition methods can generate material libraries 2,3 , these suffer...

Optimized via machine learning, extrusion printed thermoelectric materials (BiSbTe) achieve an ultrahigh zT of 1.3 at room temperature.
The ability to synthesize compositionally complex nanostructures rapidly is a key high-throughput functional materials discovery. In addition being time-consuming, majority of conventional synthesis processes closely follow thermodynamics equilibria, which limit the discovery new classes metastable phases such as high entropy oxides (HEO). Herein, photonic flash HEO nanoparticles at timescales milliseconds demonstrated. By leveraging abrupt heating and cooling cycles induced by...
Optimizing material compositions often enhances thermoelectric performances. However, the large selection of possible base elements and dopants results in a vast composition design space that is too to systematically search using solely domain knowledge. To address this challenge, hybrid data-driven strategy integrates Bayesian optimization (BO) Gaussian process regression (GPR) proposed optimize five (Ag, Se, S, Cu, Te) AgSe-based materials. Data collected from literature provide prior...
Thermoelectric materials, which can convert waste heat into electricity or act as solid‐state Peltier coolers, are emerging key technologies to address global energy shortages and environmental sustainability.

This work demonstrates a remarkable room-temperature figure of merit zT 1.3 for BiSbTe-based composites with excellent reproducibility using scalable, low-cost ink processing technique.
We investigate scalable factors for the synthesis of thermoelectric V–VI chalcogenide nanoplates and systematically study their colloidal behavior chemical stability in various ink formulations solution-based additive manufacturing.
The recent push for the “materials by design” paradigm requires synergistic integration of scalable computation, synthesis, and characterization. Among these, techniques efficient measurement thermal transport can be a bottleneck limiting experimental database size, especially diverse materials with range roughness, porosity, anisotropy. Traditional contact measurements have challenges throughput lack spatially resolvable property mapping, while non-contact pump-probe laser methods generally...
This study is concerned with the behavior of stress and strain in a thick walled functionally graded material (FGM) cylinder under internal pressure. The incompatible eigenstrain equivalent developed cylinder, are taken into account. As demonstration, TiC/Al2O3 FGM considered different components presented order to effects pressure, temperature difference (between room sintering temperature), wall thickness distribution. numerical result here shows that thermoelastic characteristic like an...
