Published New study offers improved strategy for social media communications during wildfires
(via sciencedaily.com) Original source New research offers an improved strategy for social media communications during wildfires and contradicting existing crisis communication theory.
Published Simultaneous large wildfires will increase in Western U.S.
(via sciencedaily.com) Original source Simultaneous outbreaks of large wildfires will become more frequent in the Western United States this century as the climate warms, putting major strains on efforts to fight fires, according to new research. The most severe wildfire seasons will become at least twice as frequent.
Published Extreme fires and heavy rainfall driving platypuses from their homes
(via sciencedaily.com) Original source Australia's emerging pattern of severe mega bushfires and heavy rainfall may be driving platypuses from their homes, a new study has shown. Analysis of platypus DNA in rivers and creek water samples collected before and after the Black Summer 2019-2020 megafires suggest Australia's beloved semi-aquatic monotremes might be abandoning severely bushfire-affected areas for up to 18 months after a fire, especially if heavy rainfall has followed the fire.
Published Controlled burns help prevent wildfires; Climate change is limiting their use
(via sciencedaily.com) Original source Climate change means the American West will have 17% fewer safe days to light prescribed fires for wildfire management, according to new research. Winter, however, will see a net 4% increase in the number of favorable days. Implementing controlled burns in the West will require changes to policy and the availability of firefighters.
Published Climate and human land use both play roles in Pacific island wildfires past and present
(via sciencedaily.com) Original source It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.
Published Ball milling provides high pressure benefits to battery materials
(via sciencedaily.com) Original source Cheaper, more efficient lithium-ion batteries could be produced by harnessing previously overlooked high pressures generated during the manufacturing process.
Published Unlocking the potential of silicon anode materials for commercialized batteries
(via sciencedaily.com) Original source A research team presented an analysis protocol to evaluate silicon cathode materials applicable to commercialized batteries.
Published Novel battery technology with negligible voltage decay
(via sciencedaily.com) Original source A pivotal breakthrough in battery technology that has profound implications for our energy future has been achieved.
Published A new twist on rechargeable battery performance
(via sciencedaily.com) Original source Rechargeable battery performance could be improved by a new understanding of how they work at the molecular level. Researchers upend what's known about how rechargeable batteries function.
Published Scientists reveal what fuels wildfires in Sierra Nevada Mountains
(via sciencedaily.com) Original source Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there's a growing need to know exactly what fuels the blazes after they ignite. Scientists now report that one of the chief fuels of wildfires in California's Sierra Nevada mountains is the decades-old remains of large trees.
Published By air, rain and land: How microbes return after a wildfire
(via sciencedaily.com) Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.
Published One-atom-thick ribbons could improve batteries, solar cells and sensors
(via sciencedaily.com) Researchers created nanoribbons made of phosphorus and tiny amounts of arsenic, which they found were able to conduct electricity at temperatures above -140 degrees Celsius, while retaining the highly useful properties of the phosphorus-only ribbons.
Published Sustainable energy for aviation: What are our options?
(via sciencedaily.com) Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.
Published Socially vulnerable populations are disproportionately exposed to wildfires in the Western US
(via sciencedaily.com) Original source People experiencing a high degree of social vulnerability are also more exposed to wildfires in Oregon and Washington as wildfire risk increases, a new study shows.
Published Alarming results from world first study of two decades of global smoke pollution
(via sciencedaily.com) Original source The world's first study of the increase in pollution from landscape fires across the globe over the past two decades reveals that over 2 billion people are exposed to at least one day of potentially health-impacting environmental hazard annually -- a figure that has increased by 6.8 per cent in the last ten years.
Published Researchers offer insights into solid-electrolyte interphases in next-gen aqueous potassium-ion batteries
(via sciencedaily.com) Aqueous potassium-ion batteries are a promising alternative to lithium-ion batteries owing to their safety and low cost. However, not much is known about the properties of the solid-electrolyte interphases (SEI) that form between the electrode and the aqueous electrolyte. To address this knowledge gap, researchers from Japan have now conducted a study using advanced scanning electrochemical microscopy and operando electrochemical mass spectrometry. Their findings provide a deeper understanding of SEI in next-generation batteries.
Published Almost half of koala habitats will be under high bushfire threat by 2070
(via sciencedaily.com) The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Pixel-by-pixel analysis yields insights into lithium-ion batteries
(via sciencedaily.com) By mining X-ray images, researchers have made significant new discoveries about the reactivity of lithium iron phosphate, a material used in batteries for electric cars and in other rechargeable batteries.
Published Largest historic fire death toll belongs to aftermath of 1923 Japan Earthquake
(via sciencedaily.com) Original source Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kant earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history -- comparable to the number of people killed in the World War II atomic bombing of Hiroshima. The story of the conflagration, not well-known outside of Japan, holds important lessons for earthquake scientists, emergency response teams and city planners, according to a new article.
