| By keeping ferroelectric 'bubbles' intact, researchers pave way for new devices Posted: 19 Nov 2021 12:55 PM PST Scientists have discovered that ferroelectric bubbles remain intact and retain their electronic and electromechanical (piezoelectric) properties in a freestanding state. The discovery offers promise for novel microelectronics and energy-related applications. |
| Tech companies underreport CO2 emissions Posted: 18 Nov 2021 05:35 PM PST Companies in the digital technology industry are significantly underreporting the greenhouse gas emissions arising along the value chain of their products. Across a sample of 56 major tech companies surveyed, more than half of these emissions were excluded from self-reporting in 2019. At approximately 390 megatons carbon dioxide equivalents, the omitted emissions are in the same ballpark as the carbon footprint of Australia. The research team has developed a method for spotting sources of error and calculating the omitted disclosures. |
| Bacteria may be key to sustainably extracting earth elements for tech Posted: 18 Nov 2021 03:16 AM PST A new study describes a proof of principle for engineering a bacterium, Gluconobacter oxydans, that takes a big first step towards meeting skyrocketing rare earth element demand in a way that matches the cost and efficiency of traditional thermochemical extraction and refinement methods and is clean enough to meet U.S. environmental standards. |
