• Rapid sintering can trigger grain boundary metastability. • Grain boundary metastability can interact with densification kinetics and microstructural evolution. • Scaling laws can exist correlating metastability with the particle size. • Grain boundary metastability can explain different phenomena observed during sintering. Grain boundaries (GB) are critical in polycrystalline ceramics. They co…

Reversible intercalation of guest ions in graphite laid the foundation of modern battery technology, exemplified by the successful launch of Li-ion batteries (LIBs) 35 years ago. With sodium’s natural abundance and low cost, sodium ion batteries (SIBs) are increasingly regarded an appealing contender for large-scale energy storage. However, the conventional intercalation chemistry that unlocks gr…

• A thermoelectric—driven NO 2 gas sensor based on MWCNT/PPy was developed. • PPy plays a dual role: a gas-sensing material detecting NO 2 , and a thermoelectric material generating power to supply the sensor. • Incorporation of 0.375 wt% MWCNT boosts NO₂ adsorption capacity by 207% and increases the Seebeck coefficient by 42.05%. • The maximum response to 300 ppm NO₂ hits 55.50% at 0.375 wt% MWC…

The unprecedented advancement of artificial intelligence has placed immense demands on computing hardware, but traditional silicon-based semiconductor technologies are approaching their physical and economic limit, prompting the exploration of novel computing paradigms. Memristor offers a promising solution, enabling in-memory analog computation and massive parallelism, which leads to low latency…
