Ultrathin Quantum Dot LED that Can be Folded Freely as Paper
Ultrathin Quantum Dot LED that Can be Folded Freely as Paper Quantum dot light-emitting diode (QLED), which employs quantum dots as a light-emitting material, has attracted significant attention as a promising alternative for next-generation display technologies, owing to its outstanding electroluminescence properties. Since it does not require any bulky components such as backlight units, QLED displays can potentially be manufactured into an ultrathin form factor. A joint research team led by KIM Dae-Hyeong (Professor at Seoul National University) and HYEON Taeghwan (Distinguished professor at Seoul National University) from the Center for Nanoparticle Research within the Institute for Basic Science has previously unveiled a prototype QLED back in 2015. The device had a thickness of only 3 micrometers, which is only one-thirtieth of that of human hair. Due to such an extremely reduced thickness, the ultrathin QLED exhibited outstanding mechanical flexibility, which allowed it to be readily applicable in various wearable devices, such as electronic tattoos.

Aledia Has Produced Its First Nanowire Chips on 300mm Silicon Wafers Using CEA-Leti Pilot Lines
Aledia Has Produced Its First Nanowire Chips on 300mm Silicon Wafers Using CEA-Leti Pilot Lines Aledia, a French startup pioneering a disruptive technology for microLED displays, today announced it has manufactured the world's first microLED chips produced on 300 mm (12") silicon wafers. The company, which developed its breakthrough technology on 200 mm (8") silicon wafers over the past eight years, will produce the chips on both 200 mm and 300 mm wafers. The larger wafers provide better economic payoff and cost-effective integration with smaller-node electronics, which are only available on 300 mm silicon wafers. Aledia was spun out of CEA-Leti, a French research institute pioneering micro- and nanotechnologies, in 2012, and the work on 300 mm wafers has been performed by joint Aledia and CEA-Leti teams.

Research Shows that Streetlights Contribute Less to Nighttime Light Emissions in Cities than Expected
Research Shows that Streetlights Contribute Less to Nighttime Light Emissions in Cities than Expected When satellites take pictures of Earth at night, how much of the light that they see comes from streetlights? A team of scientists from Germany, the USA, and Ireland have answered this question for the first time using the example of the U.S. city of Tucson, thanks to "smart city" lighting technology that allows cities to dim their lights. The result: only around 20 percent of the light in the satellite images of Tucson comes from streetlights. The study is published today in the journal "Lighting Research & Technology". Read more »
