| Magnetic ‘hedgehogs’ could store big data in a small space Posted: 17 Dec 2021 08:32 AM PST Atomic-scale magnetic patterns resembling a hedgehog's spikes could result in hard disks with massively larger capacities than today's devices, a new study suggests. The finding could help data centers keep up with the exponentially increasing demand for video and cloud data storage. |
| Posted: 16 Dec 2021 12:00 PM PST Researchers have pioneered a new fabrication technique that enables them to produce low-voltage, power-dense, high endurance soft actuators for an aerial microrobot. These artificial muscles vastly improve the robot's payload and allow it to achieve best-in-class hovering performance. |
| Demonstrating Feshbach resonances between a single ion and ultracold atoms Posted: 16 Dec 2021 11:59 AM PST A team has demonstrated magnetic Feshbach resonances between a single barium ion and lithium atoms at near absolute zero temperature. The researchers found that depending on the strength of the external magnetic field, the expansion of the ion and atoms can be controlled. |
| Nanoparticle therapeutic enhances cancer immunotherapy Posted: 16 Dec 2021 11:59 AM PST Researchers have discovered that a nanoparticle therapeutic enhances cancer immunotherapy and is a possible new approach in treating malignant pleural effusion (MPE). MPE is the accumulation of fluid between the chest wall and lungs and is accompanied by malignant cells and/or tumors. |
| Fabricating stable, high-mobility transistors for next-generation display technologies Posted: 16 Dec 2021 11:58 AM PST The trade-off between carrier mobility and stability in amorphous oxide semiconductor-based thin film transistors (TFTs) has been finally overcome by researchers in an ingeniously fabricated indium tin zinc oxide TFT. This could pave the way for the design of display technologies that are cheaper than current silicon-based technologies. |
| New smart-roof coating enables year-round energy savings Posted: 16 Dec 2021 11:50 AM PST Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer -- without consuming natural gas or electricity. Research findings point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings. |
| ‘Gentrification’ changes the personality make-up of cities in just a few years Posted: 15 Dec 2021 05:41 PM PST A massive study of almost two million US residents reveals rising housing costs may drive increases in 'openness' of character among both old and new inhabitants of a city -- all in well under a decade. |
| New crystal structure for hydrogen compounds for high-temperature superconductivity Posted: 13 Dec 2021 06:49 AM PST Since the discovery of low-temperature superconductors, there has been an ongoing effort to realize superconductivity at room temperatures with low cooling costs. Crystalline materials containing hydrogen have shown promise on this front. Now, a global team of researchers have performed simulations to predict new crystal structures with hydrogen atoms as potential high-temperature superconductors, opening doors to energy-efficient technologies with lossless power transmission. |
