Say 'bye bye' to faulty mobile phones and solar cells
Say ’bye bye’ to faulty mobile phones and solar cells
Faulty mobile phones and solar cells could soon be a thing of the past thanks to a ground-breaking invention developed at The Australian National University (ANU). Engineers have developed a powerful new tool to help manufacturers spot defects or unwanted features in everyday technology - such as mobile phones, batteries and solar cells - more easily and much earlier in the fabrication process.

Mechanism helps explain the ear's exquisite sensitivity
Mechanism helps explain the ear’s exquisite sensitivity
A critical gel-like structure in the inner ear moves according to a sound's frequency, researchers find. The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered important new details of how the ear achieves this amazing ability to pick up faint sounds.

Rare metals from e-waste
Rare metals from e-waste
This year, beautifully wrapped laptops, mobile phones or even new TV sets lay under numerous Christmas trees. They are enthusiastically put into use - and the old electronic devices are disposed of. The e-waste contains resources such as neodymium, indium and gold. What happens to the valuable materials' And how much rare metal is contained in mobile phones, computers and monitors that are still in use today? Empa researchers have investigated these questions.

Excitons pave the way to more efficient electronics
Excitons pave the way to more efficient electronics
After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices. They were the first to control exciton flows at room temperature. And now, the team of scientists from EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) has taken their technology one step further.
