| Ultrashort-pulse lasers kill bacterial superbugs, spores Posted: 23 Nov 2021 01:28 PM PST Researchers at Washington University School of Medicine in St. Louis have found that multidrug-resistant bacteria and bacterial spores can be killed by ultrashort-pulse lasers. The findings could lead to new ways to sterilize wounds and blood products without damaging human cells. |
| Microbes can provide sustainable hydrocarbons for the petrochemical industry Posted: 23 Nov 2021 01:28 PM PST The petrochemical industry turns oil and gas into precursors used to synthesize lubricants and other critical products. Chemists show that bacteria can be metabolically engineered to generate similar precursors, providing a sustainable replacement for fossil fuels and using less energy. The microbes need only glucose. The medium-chain hydrocarbons they produce can be broken down into shorter chains and polymerized into plastics, or lengthened to make products such as diesel. |
| How sugar-loving microbes could help power future cars Posted: 22 Nov 2021 10:53 AM PST It sounds like modern-day alchemy: Transforming sugar into hydrocarbons found in gasoline. But that's exactly what scientists have done. Researchers report harnessing the wonders of biology and chemistry to turn glucose (a type of sugar) into olefins (a type of hydrocarbon, and one of several types of molecules that make up gasoline). |
| 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. |
| New research could help boost growth of clean cooking in sub-Saharan Africa Posted: 18 Nov 2021 05:36 PM PST Researchers have new evidence that could help rapidly boost efforts to scale-up the adoption of clean cooking with liquefied petroleum gas (LPG) in sub-Saharan Africa. The new study suggests that supply-side interventions such as shortening the distance to LPG retail points and improving access to multi-burner LPG stoves could help increase the consumption of the clean cooking fuels, for the benefit of public health, gender equality and environmental protection. |
| Prize-winning technology for large-scale energy storage Posted: 18 Nov 2021 05:36 PM PST Safe, cheap and sustainable technology for energy storage has been developed. It is based on two major breakthroughs: the manufacture of wood-based electrodes in rolled form, and a new type of water-based electrolyte. |
| Posted: 18 Nov 2021 05:35 PM PST An international research team has developed a new imaging technology. In the future this technology could not only improve the resolution of neutron measurements by many times but could also reduce radiation exposure during x-ray imaging. |
| Developing high-performance MXene electrodes for next-generation powerful battery Posted: 18 Nov 2021 05:35 PM PST Two-dimensional MXene has been a rising star in the energy world as this material can store energy fast. But their unstable voltage output limits their applications. A collaborative research team has recently developed battery-like electrochemical Nb2CTx MXene electrodes with stable voltage output and high energy density by using a high-voltage scanning strategy. These latest findings may lead to a breakthrough in inventing the powerful battery of the next generation. |
| Research team makes considerable advance in brain-inspired computing Posted: 16 Nov 2021 07:31 AM PST A lab, whose work is concentrated on neuromorphic computing or brain-inspired computing, has new research that introduces hardware improvements by harnessing a quality known as 'randomness' or 'stochasticity'. Their research contradicts the perception of randomness as a quality that will negatively impact computation results and demonstrates the utilization of finely controlled stochastic features in semiconductor devices to improve performing optimization. This has potential to create a more sophisticated building block for creating computers that can tackle sophisticated optimization problems, which can potentially be more efficient. What's more they can consume less power. |
