How sensitive can a quantum detector be?

A new device measures the tiniest energies in superconducting circuits, an essential step for quantum technology.

A superlattice based STT-MRAM with extra-high performance

Researchers have developed a superlattice based STT-MRAM with extra-high performance, called SS-MARM or SL-STT-MARM, which has several advantages, including not only ultra-low power consumption, ultra-high MR ratio, high-speed writing and low RA but also high endurance and simple manufacturing, comparing to traditional STT-MRAM.

Edible 'security tag' to protect drugs from counterfeit

Researchers are aiming to stump counterfeiters with an edible 'security tag' embedded into medicine. To imitate the drug, a counterfeiter would have to uncrack a complicated puzzle of patterns not fully visible to the naked eye.

Light powers world's fastest-spinning object

Nanoparticle levitated by light rotates at 300 billion rpm.

Colloidal quantum dot photodetectors can now see further than before

An new study reports on the development of a colloidal quantum dot photodetector capable of detecting light in the far infrared.

Pretty with a twist

Complex, porous, chiral nanopatterns arise from a simple linear building blocks.

Brain-like network uses disorder to create order

A disordered network that is capable of detecting ordered patterns: it sounds contradictory, but it comes close to the way our brain works.
