Electric pulses precisely shape 3-D-printed metal parts

Professor Dirk Bähre and his research team at Saarland University have developed a non-contact method of transforming metal parts fabricated by a 3-D printer into high-precision technical components for specialist applications. ...

Engineers develop near-zero emissions engine technology

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NOx) and carbon dioxide emissions while minimizing fuel consumption. Working ...

High-security identification that cannot be counterfeited

Try whispering at one end of the Echo Wall in the Temple of Heaven in Beijing. People at the far end of the curved wall will hear you from 65 meters away. This is the whispering-gallery effect. Now, researchers from Japan ...

New and improved drone mapping software

For his thesis, an EPFL Ph.D. student has enhanced the accuracy and reliability of drone mapping—a technique that is gaining traction across many sectors of society.

Artificial eye comes closer to human eye capabilities

A team of researchers at The Hong Kong University of Science and Technology, the University of California, Berkeley and Lawrence Berkeley National Laboratory has built an artificial eye with capabilities that come close to ...

Researchers build a fast-moving jumping soft robot

Buckling, the sudden loss of structural stability, is usually the stuff of engineering nightmares. Mechanical buckling means catastrophic failure for every structural system from rockets to soufflés. It's what caused the ...

Image fusion method for underground pipeline leakage detection

The water supply network is closely connected to all aspects of society. Acoustic methods could be applied to underground pipe network monitoring and leakage detection through measurements using acoustic/vibration sensors ...

Self-healing devices gain or regain function after being cut

A "smart" polymer cast that automatically seals itself around a broken arm, a membrane that can sense where it has been cut, and pneumatic actuators that can be cut and reconfigured into different shapes are some possible ...
