Reading magnetic states faster — in far infrared

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic states can be read out by short current pulses, whereby recently discovered spintronic effects in purpose-built material systems could remove previous speed restrictions. Researchers are now

Spinning, twisted light could power next-generation electronics

Researchers have advanced a decades-old challenge in the field of organic semiconductors, opening new possibilities for the future of electronics. The researchers have created an organic semiconductor that forces electrons to move in a spiral pattern, which could improve the efficiency of OLED displays in television and smartphone screens, or power next-generation computing technologies such

Catching aromaticity in the act: Direct real-time tracking of how ‘excited-state aromaticity’ drives molecular shape changes

Scientists have achieved the first real-time visualization of how ‘excited-state aromaticity’ emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar structure in a few picoseconds. By combining ultrafast electronic and vibrational spectroscopies, the team captured these fleeting structural changes at the molecular level and showed that aromaticity
