Posted: 15 May 2020 11:46 AM PDT Moisture is the main environmental factor that triggers the degradation of the masterpiece The Scream (1910) by Edvard Munch, according to new findings using a combination of in situ non-invasive spectroscopic methods and synchrotron X-ray techniques. |
Scientists break the link between a quantum material's spin and orbital states Posted: 15 May 2020 10:19 AM PDT Until now, electron spins and orbitals were thought to go hand in hand in a class of materials that's the cornerstone of modern information technology; you couldn't quickly change one without changing the other. But a new study shows that a pulse of laser light can dramatically change the spin state of one important class of materials while leaving its orbital state intact. |
Eavesdropping on single molecules with light by replaying the chatter Posted: 15 May 2020 08:56 AM PDT Scientists have pioneered a new technique to expose hidden biochemical pathways involving single molecules at the nanoscale. |
Model of critical infrastructures reveals vulnerabilities Posted: 15 May 2020 08:56 AM PDT Researchers developed a computer simulation that revealed beef supply chain vulnerabilities that need safeguarding -- a realistic concern during the COVID-19 pandemic. |
A soft touch for robotic hardware Posted: 15 May 2020 05:57 AM PDT Robots can be made from soft materials, but the flexibility of such robots is limited by the inclusion of rigid sensors necessary for their control. Researchers created embedded sensors, to replace rigid sensors, that offer the same functionality but afford the robot greater flexibility. Soft robots can be more adaptable and resilient than more traditional rigid designs. The team used cutting-edge machine learning techniques to create their design. |
Coordination polymer glass provides solid support for hydrogen fuel cells Posted: 13 May 2020 05:18 AM PDT Scientists are synthesizing stronger and more efficient materials for hydrogen fuel cell membranes. Most fuel cells currently on the market employ liquid membranes. A new coordination polymer glass membrane works just as well as its liquid counterparts with added strength and flexibility. |
Inexpensively locating friendly (and unfriendly) radio waves Posted: 12 May 2020 04:00 PM PDT Electrical engineers have devised a low-cost method for passively locating sources of radio waves such as Wi-Fi and cellular communication signals. The technique could lead to inexpensive devices that can find radio wave devices like cellular phones or Wi-Fi emitters and cameras that can capture images using the radio waves already bouncing around the world all around us. |
Electronic diodes beyond 5G performance created Posted: 12 May 2020 10:45 AM PDT Researchers have developed a new resonant tunneling diode (RTD) with performance beyond the anticipated speed of 5G. |
On the road to non-toxic and stable perovskite solar cells Posted: 11 May 2020 12:49 PM PDT The promising halide perovskite materials for solar energy conversion show high efficiencies, but this comes at a cost: The best perovskite materials incorporate toxic lead which poses a hazard to the environment. Researchers have now engineered a new hybrid perovskite material with promising efficiency and stability. |
