| Near-field routing of hyperbolic metamaterials Posted: 14 Jun 2021 12:39 PM PDT Researchers recently demonstrated an all-electric scheme able to flexibly control the propagation direction of near-field light. |
| Insulators turn up the heat on quantum bits Posted: 14 Jun 2021 12:39 PM PDT Physicists have long suspected that dielectric materials may significantly disrupt ion-trap quantum computers. Now, researcher have developed a new method to quantify this source of error for the first time. For the future operation of quantum computers with very many quantum bits, such noise sources need to be eliminated already during the design process if possible. |
| New combination of materials provides progress toward quantum computing Posted: 14 Jun 2021 12:39 PM PDT Engineers have demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices' properties. Specifically, the interaction between electrons becomes so strong that they form a new structure known as a correlated insulating state. This is an important step, researchers said, toward developing quantum emitters needed for future quantum simulation and computing. |
| Peering inside 2D crystal synthesis Posted: 14 Jun 2021 10:12 AM PDT Theorists simulate the molecular transitions that take place inside a furnace to create 2D molybdenum disulfide, a semiconductor that could find a home in next-generation electronics. |
| From milk protein, a plastic foam that gets better in a tough environment Posted: 14 Jun 2021 08:08 AM PDT A new high-performance plastic foam developed from whey proteins can withstand extreme heat better than many common thermoplastics made from petroleum. A research team reports that the material, which may be used for example in catalysts for cars, fuel filters or packaging foam, actually improves its mechanical performance after days of exposure to high temperatures. |
| Engineers devise novel approach to wirelessly power wearable devices Posted: 14 Jun 2021 08:08 AM PDT Researchers have come up with a way to use one single device - such as a mobile phone or smart watch - to wirelessly power up to 10 wearables on a user. This novel method uses the human body as a medium for transmitting power. Their system can also harvest unused energy from electronics in a typical home or office environment to power the wearables. |
| AI predicts how patients with viral infections, including COVID-19, will fare Posted: 11 Jun 2021 08:08 AM PDT Gene expression patterns associated with pandemic viral infections provide a map to help define patients' immune responses, measure disease severity, predict outcomes and test therapies -- for current and future pandemics. |
