Stacking extremely thin films of material on top of each other can create new materials with exciting new properties. But the most successful processes for building those stacks can be tedious and imperfect, and not well suited for large-scale production.Now a team led by Stanford Professor Hemamala Karunadasa has created a much simpler and faster way to do it. They grew 2D layers of one of the most sought-after materials, known as perovskites, interleaved with thin layers of other materials in large crystals that assemble themselves.

Smartphones, laptops, and lighting applications rely on light-emitting diodes (LEDs) to shine bright. But the brighter these LED technologies shine, the more inefficient they become, releasing more energy as heat instead of light.Now, as reported in the journal Science, a team led by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has demonstrated an approach for achieving near 100% light-emission efficiency at all brightness levels.

Thanks to AI, we just got stunningly powerful tools to decode life.In two back-to-back papers last week, scientists at DeepMind and the University of Washington described deep learning-based methods to solve protein folding—the last step of executing the programming in our DNA, and a “once in a generation advance.”

Nashua, New Hampshire – Pfeiffer Vacuum has introduced its new HiPace 80 Neo turbopump, which features a longer life before service and reduced vibration and noise emissions. These benefits are made possible with the new, advanced Laser Balancing™ system developed by Pfeiffer Vacuum for turbopump rotors. This patented technology, makes the vacuum pump particularly suitable for vibration-sensitive applications. Possible applications range from mass spectrometry and electron microscopy to leak detectors and RGA systems.
