Making microscopic machines using metallic glass

Researchers in Ireland have developed a new technology using materials called bulk metallic glasses to produce high-precision molds for making tiny plastic components. The components, with detailed microscopically patterned ...

Defective plastics repair themselves

Indestructible things are a figment of the imagination of advertising. Even plastic components that have to stand up to major mechanical loads can break. The reason for this are microcracks that may be found in any component ...

Laser welding in the right light

Laser welding is on the advance, but it also has its limits: it has been impossible to fuse two transparent plastic components together -- up until now. German researchers have now succeeded in circumventing this hurdle -- ...

Impregnating plastics with carbon dioxide

Everyone has heard that carbon dioxide is responsible for global warming. But the gas also has some positive characteristics. Researchers are now impregnating plastics with compressed CO2 in a process that could lead to new ...

Woven electronics

Electrical engineers from ETH Zurich have devised intelligent textiles that already have electronic components such as sensors and conductive filaments woven into them. The advantage: the fabric can be mass-produced on conventional ...

Japan mines toxic e-waste for precious materials

Seeking to turn an environmental problem into an economic opportunity, high-tech companies in resource-poor Japan are mining mountains of toxic e-waste for precious materials.
