| New breathable gas sensors may improve monitoring of health, environment Posted: 19 May 2022 01:19 PM PDT Newly developed flexible, porous and highly sensitive nitrogen dioxide sensors that can be applied to skin and clothing have potential applications in health care, environmental health monitoring and military use, according to researchers. |
| Using everyday WiFi to help robots see and navigate better indoors Posted: 19 May 2022 12:01 PM PDT Engineers have developed a low cost, low power technology to help robots accurately map their way indoors, even in poor lighting and without recognizable landmarks or features. The technology uses WiFi signals, instead of light, to help the robot 'see' where it's going. |
| Scientists devise method to prevent deadly hospital infections without antibiotics Posted: 19 May 2022 12:01 PM PDT Some 1.7 million Americans each year acquire hospital infections, resulting in nearly 100,000 deaths from infection-related complications. The biggest culprits: medical devices like catheters, stents and heart valves, whose surfaces often become covered with harmful bacterial films. A novel surface treatment developed by a UCLA-led team of scientists stops microbes from adhering to medical devices. The new findings are published May 19 in the journal Advanced Materials. |
| Is it topological? A new materials database has the answer Posted: 19 May 2022 11:09 AM PDT A new materials database reveals more than 90,000 known 'topological' materials with persistent electronic properties. |
| How a cognitive bias is blocking the rise of electric cars Posted: 19 May 2022 09:56 AM PDT What are the barriers to the adoption of electric cars? Although the main financial and technological obstacles have been removed, their market share still needs to increase. In a recent study, a team investigated the cognitive factors that still dissuade many people from switching to electric cars. They found that car owners systematically underestimate the capacity of electric driving ranges to meet their daily needs. |
| CRISPR-based strategy edits multiple genes and could treat polygenic diseases Posted: 19 May 2022 08:53 AM PDT Engineers introduce DAP, a streamlined CRISPR-based technology that can perform many genome edits at once to address polygenic diseases caused by more than one glitch. |
| New process revolutionizes microfluidic fabrication Posted: 19 May 2022 08:53 AM PDT Microfluidic devices use tiny spaces to manipulate very small quantities of liquids and gasses by taking advantage of the properties they exhibit at the microscale. They have demonstrated usefulness in applications from inkjet printing to chemical analysis and have great potential in personal medicine, where they can miniaturize many tests that now require a full lab, lending them the name lab-on-a-chip. |
| Low-cost battery-like device absorbs CO2 emissions while it charges Posted: 19 May 2022 08:53 AM PDT Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be reused or disposed of responsibly. |
| New thermal management technology for electronic devices reduces bulk while improving cooling Posted: 19 May 2022 08:53 AM PDT Electronic devices generate heat, and that heat must be dissipated. The high temperatures can compromise device function or even damage the devices and surroundings if it isn't. Now, a team has detailed a new cooling method that offers a host of benefits, not the least of which is space efficiency which offers a substantial increase over conventional approaches in devices' power per unit volume. |
| Spin keeps electrons in line in iron-based superconductor Posted: 19 May 2022 08:53 AM PDT Electronic nematicity, believed to be an important ingredient in high-temperature superconductivity, is primarily spin-driven in the iron-based superconductor FeSe, reveals a new study. |
| Broadening the scope of epoxide ring opening reactions with zirconocene Posted: 19 May 2022 07:38 AM PDT Epoxide, a cyclic ether, can be used to obtain important alcohols, pharmaceuticals, agrochemicals, and functional polymers. This transformation is facilitated by the reductive ring opening of epoxide. Traditionally, the reaction has been catalyzed using titanocene. However, in this case, the products are predominantly obtained via more stable radicals. Now, chemists turn the tables and broaden the scope of this reaction using zirconocene as a novel catalyst under visible light irradiation. |
| Ions and Rydberg-atoms: A bond between David and Goliath Posted: 19 May 2022 07:38 AM PDT Researchers have verified a novel binding mechanism forming a molecule between a tiny charged particle and in atomic measures gigantic Rydberg atom. The scientists could observe spatially resolved the molecule with the help of a self-build ion microscope. |
| Synthesis of two-dimensional holey graphyne Posted: 18 May 2022 08:38 AM PDT A new type of carbon allotrope, holey graphyne, has semiconductor properties and is applicable in various fields such as photoelectronics, sensors, and water purification. |
