A new ultrafast control scheme of ferromagnet for energy-efficient data storage

Using a single laser pulse that did not switch the ferrimagnetic layer, researchers demonstrated a much faster and less energy consuming switching of the ferromagnet.

Sprinkled with power: How impurities enhance a thermoelectric material at the atomic level

Scientists elucidate how antimony impurities improve the performance of magnesium silicide, a promising material for converting waste heat into electricity.

All-terrain microrobot flips through a live colon (w/video)

A rectangular robot as tiny as a few human hairs can travel throughout a colon by doing back flips, engineers have demonstrated in live animal models.

Researchers develop a plant-based thermotherapy patch

Researchers developed a biodegradable, transparent, flexible and fast-acting thermotherapy patch from plant leaves. The patch is compatible with flexible electronic applications. Plant material was used to reduce the amount of electronic waste.

Quantum engines with entanglement as fuel?

It's still more science fiction than science fact, but perfect energy efficiency may be one step closer due to new research.

Altering the properties of 2D materials at the nanometer scale

Scientists have developed a method for changing the physical properties of 2D materials permanently using a nanometric tip. Their approach, which involves deforming the materials, paves the way to using these materials in electronic and optoelectronic devices.

Now you see it, now you don't: Hidden colours discovered by coincidence (w/video)

Our understanding of how light behaves has grown with the surprising discovery that colours can be seen in a new way. An example of a process called scattering, the effect occurs in some materials when light interference combines with strong electric fields.
