Advanced pure copper 3D printing with sub-micron resolution

High-quality data transmission, high-precision information sensing, and high-sensitivity signal detection are important means to achieve precise perception and effective identification. High-performance chips, terahertz transmission ...

Engineers turn plastic insulator into heat conductor

Plastics are excellent insulators, meaning they can efficiently trap heat - a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic ...

Researchers upend conventional wisdom on thermal conductivity

Scientists have long known that diamond is the best material for conducting heat, but it has drawbacks: It is costly and is an electrical insulator; when paired with a semiconductor device, diamond expands at a different ...
