Since the discovery of superconductivity in Sr₂RuO₄ in 1,994 hundreds of studies have been published on this compound, which have suggested that Sr₂RuO₄ is a very special system with unique properties. These properties make Sr₂RuO₄ a material with great potential, for example, for the development of future technologies including superconducting spintronics and quantum electronics by virtue of its ability to carry lossless electrical currents and magnetic information simultaneously. An international research team led by scientists at the University of Konstanz has been now able to answer one of the most interesting open questions on Sr₂RuO₄: why does the superconducting state of this material exhibit some features that are typically found in materials known as ferromagnets, which are considered being antagonists to superconductors? The team has found that Sr₂RuO₄ hosts a new form of magnetism, which can coexist with superconductivity and exists independently of superconductivity as well. The results have been published in the current issue of Nature Communications.

After a research study that lasted several years and involved 26 researchers from nine different universities and research institutions, the missing piece of the puzzle seems to have been found. Alongside the University of Konstanz, the universities of Salerno, Cambridge, Seoul, Kyoto and Bar Ilan as well as the Japan Atomic Energy Agency, the Paul Scherrer Institute and the Centro Nazionale delle Ricerche participated in the study.

A county in Washington on Tuesday confirmed that a woman died from blood-clotting complications after receiving Johnson & Johnson’s single-dose COVID-19 vaccine. She is believed to be the fourth person to have died from such a complication.

Tesla’s impressive third-quarter delivery performance overshadowed the automotive industry’s ongoing struggle with the semiconductor chip shortage. Among all of the world’s automakers, Tesla has been basically the only car company to avert the crisis as it has not had any overwhelmingly public stoppages in vehicle production. Morgan Stanley’s new investor note, drafted by lead analyst Adam Jonas, examines Tesla’s ability to avoid detrimental production stoppages, which effectively helped the company capture its best quarter in company history.

Jonas titles Morgan Stanley’s most recent investor note, “How Did Tesla Find Chips?” In all honesty, this riddle was solved during the Q2 2021 Earnings Call, where Tesla stated in its Shareholder Deck that it used a combination of in-house microcontrollers to avoid any major catastrophes in the manufacturing of its vehicles. The company wrote:

“Our team has demonstrated an unparalleled ability to react quickly and mitigate disruptions to manufacturing caused by semiconductor shortages. Our electrical and firmware engineering teams remain hard at work designing, developing and validating 19 new variants of controllers in response to ongoing semiconductor shortages.”

Imagine an iPad or a Kindle for the blind, with inflatable Braille that changes shape under a user’s touch. A Cornell-led collaboration has made a crucial component for such a technology: A haptic array of densely packed actuators that cause silicone membrane “dots” to pop up when triggered by combustion.

The team’s paper, “Valveless Microliter Combustion for Densely Packed Arrays of Powerful Soft Actuators,” published Sept. 28 in Proceedings of the National Academy of Sciences. The lead author is doctoral student Ronald Heisser.

One of the major hurdles for designing a dynamic Braille display for electronics is figuring out how to apply the necessary amount of force for each dot. Previous attempts have usually involved motors, hydraulics or tethered pumps, all of which are cumbersome, complex and expensive, according to Rob Shepherd, associate professor of mechanical and aerospace engineering in the College of Engineering and the paper’s senior author.
