(via sciencedaily.com) Original source An international coalition of climate scientists says that the Earth's vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
Published Cathode active materials for lithium-ion batteries could be produced at low temperatures
(via sciencedaily.com) Original source Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes.
Published A step on the way to solid-state batteries
(via sciencedaily.com) Original source A lithium ceramic could act as a solid electrolyte in a more powerful and cost-efficient generation of rechargeable lithium-ion batteries. The challenge is to find a production method that works without sintering at high temperatures. A research team has now introduced a sinter-free method for the efficient, low-temperature synthesis of these ceramics in a conductive crystalline form.
Published New extremes in stratospheric water vapor
(via sciencedaily.com) Original source The focus of new research was to determine how deep, how much and how frequently water in the stratosphere was being increased by thunderstorms.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published A miniature magnetic resonance imager made of diamond
(via sciencedaily.com) Original source The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team has now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging.
Published Cobalt-free battery for cleaner, greener power
(via sciencedaily.com) Original source High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. A team now presents a viable alternative to cobalt which in some ways can outperform state-of-the-art battery chemistry. It also survives a large number of recharge cycles, and the underlying theory can be applied to other problems.
Published New study finds 50-year trend in hurricane escalation linked to climate change
(via sciencedaily.com) Original source New research by climate scientists indicates that there have been great changes to Atlantic hurricanes in just the past 50 years, with storms developing and strengthening faster.
Published Protecting polar bears: New and improved radar technology
(via sciencedaily.com) Original source Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers hope that improving detection tools to locate dens -- which are nearly invisible and buried under snow -- will help efforts to protect mother polar bears and their cubs.
Published Researchers unveil fire-inhibiting nonflammable gel polymer electrolyte for lithium-ion batteries
(via sciencedaily.com) Original source A research team has succeeded in developing a non-flammable gel polymer electrolyte (GPE) that is set to revolutionize the safety of lithium-ion batteries (LIBs) by mitigating the risks of thermal runaway and fire incidents.
Published As surging threats teeter electrical power grids, scientists offer insights to make them more resilient
(via sciencedaily.com) Original source Power grids -- the web of electrical networks that sprawl across countries and continents -- are under stress. Extreme weather events and volatile energy demands often push the system to the brink. Although these high-impact events can be very damaging, often overlooked is the impact of minor disruptions that trigger a domino effect throughout the system, according to a study analyzing European power blackouts. The findings showed that recovering power within 13 hours can reduce up to 52% of the power loss stemming from cascading events.
Published New recipe for efficient, environmentally friendly battery recycling
(via sciencedaily.com) Original source Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid -- an organic acid that can be found in the plant kingdom.
Published Climate network analysis helps pinpoint regions at higher risk of extreme weather
(via sciencedaily.com) Original source Climate change and the rapid increase in frequency of extreme weather events around the globe reinforces the reality that these events are interconnected. Researchers now describe a climate network analysis method to explore the intensity, distribution, and evolution of this interlinked climate behavior, or teleconnections. The analysis combines the directions and distribution patterns of teleconnections to evaluate their intensity and to identify sensitive regions using global daily surface air temperature data. The method relies on advanced data processing and mathematical algorithms to find meaningful insights.
Published Rising seas will tighten vise on Miami even for people who are not flooded, says study
(via sciencedaily.com) Original source A new study that examines both the physical and socioeconomic effects of sea-level rise on Florida's Miami-Dade County area finds that in coming decades, four out of five residents may face disruption or displacement, whether they live in flood zones or not. As inundation spreads, the effects will be felt predominantly by lower-income people as habitable areas shrink and housing prices rise, says the study. Only a small number of affluent residents will be able relocate from low-lying or waterfront properties, while many others without sufficient means may be trapped there, it says.
Published New study confirms presence of flesh-eating and illness-causing bacteria in Florida's coastal waters following Hurricane Ian
(via sciencedaily.com) Original source When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.
Published Management zone maps of little use to corn growers
(via sciencedaily.com) Original source A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study found that -- contrary to common assumptions -- crop-plot responses to the same inputs vary significantly from year to year. The most unpredictable factor -- the weather -- seemed to have the biggest impact on how the crops responded to these inputs.
Published How weather phenomena affect ocean circulation
(via sciencedaily.com) Original source A new study has investigated how future changes in weather patterns could affect the tropical Pacific Ocean and its ecosystems. The research, based on complex computer models, has shown that these changes will have far-reaching consequences for ocean circulation. The authors stress the need to take this more into account in future climate models.
