Scientists at Tokyo Institute of Technology (Tokyo Tech), Imperial and High Energy Accelerator Research Organization (KEK) Institute of Materials Structure Science, discover new Ba 7 Nb 4 MoO 20-based ...

A study, led by Tingting Zuo, was based on the idea of in-situ growth, and a series of Cu/Gr composites with improved interfaces were prepared by vacuum hot press sintering. Combined with cold-drawing ...

Pure copper has excellent electrical (~ 58 MS m −1) and thermal (~ 400 W m −1 K −1) conductivities, making it essential in electrical, electronic, and energy systems. The demand for small, ...

Oxide ion conductors used in solid-state fuel cells often fail to reach full potential when operating at temperatures below 500 degrees Celsius, but researchers have recently found a solution to this ...

Pervasive high-conductivity anomalies in shallow cold subduction zones (40–70 km depths, corresponding to 1–2 GPa) remain unexplained by conventional mechanisms (e.g., dehydration fluids). Here we ...

Semiconductors are a key component in smartphones, televisions, and other devices used in daily life using these devices generates heat, resulting in performance degradation and a shorter product life ...

Researchers have solved a long-standing puzzle about lower measured thermal conductivity values of cubic silicon carbide (3C-SiC) bulk crystals in the literature than the structurally more complex ...

Polymers are composed of very large molecules formed by a combination of different monomers (smaller and simpler molecules), which can be natural or synthetic. Polymers are the basis of many ...

Tokyo Tech researchers demonstrated high conductivity and stability in bismuth-containing Sillén oxyhalides with triple fluorite-like layers (e.g. 10 mS/cm at 431 o C; 204 times higher conductivity ...
