Published Seaweed-based battery powers confidence in sustainable energy storage
(via sciencedaily.com) A team uses nanomaterials made from seaweed to create a strong battery separator, paving the way for greener and more efficient energy storage.
Published More reasons to go solar when gearing up for a greener drive
(via sciencedaily.com) With electric vehicles sales soaring worldwide, potential buyers are not just weighing up the price tag, but also the logistics and expense of charging the planet-friendly cars. A new study shows households with solar panels and batteries will be the big winners.
Published Magnetic field helps thick battery electrodes tackle electric vehicle challenges
(via sciencedaily.com) As electric vehicles grow in popularity, the spotlight shines more brightly on some of their remaining major issues. Researchers are tackling two of the bigger challenges facing electric vehicles: limited range and slow recharging.
Published Cobalt-free cathode for lithium-ion batteries
(via sciencedaily.com) Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically problematic mineral -- from LI batteries.
Published High-accuracy electric vehicle battery monitoring with diamond quantum sensors for driving range extension
(via sciencedaily.com) The issue of battery usage inefficiency in electric vehicles resulting from an inaccurate battery charge measurement may finally get resolved, thanks to a diamond quantum sensor prototype. The sensor can measure currents in a wide range as well as detect milliampere-level currents in a noisy environment, improving the detection accuracy from 10% to within 1%.
Published Robo-bug: A rechargeable, remote-control cyborg cockroach
(via sciencedaily.com) Researchers have engineered a system for creating remote controlled cyborg cockroaches, equipped with a tiny wireless control module that is powered by a rechargeable battery attached to a solar cell. This achievement will help make the use of cyborg insects a practical reality.
Published A sustainable battery with a biodegradable electrolyte made from crab shells
(via sciencedaily.com) Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren't always sustainable themselves. Scientists have now create a zinc battery with a biodegradable electrolyte from an unexpected source -- crab shells.
Published A new concept for low-cost batteries
(via sciencedaily.com) Original source Engineers have designed a battery made from inexpensive, abundant materials, that could provide low-cost backup storage for renewable energy sources. Less expensive than lithium-ion battery technology, the new architecture uses aluminum and sulfur as its two electrode materials with a molten salt electrolyte in between.
Published New stable quantum batteries can reliably store energy into electromagnetic fields
(via sciencedaily.com) Original source Researchers have proposed that the micromasers can serve as excellent model for future quantum batteries.
Published Researchers investigate development of coastal peatland in Indonesia over thousands of years
(via sciencedaily.com) Tropical peatlands are one of the most efficient carbon sinks. The flipside is that they can become massive emitters of carbon if they are damaged, for instance by land use change, degradation or fire. This can lead to faster climate warming. Researchers now show how peatland in the coastal areas in Sumatra and Borneo in Indonesia developed over thousands of years and how climate and sea level influenced their dynamics throughout.
Published Past eight years: Warmest since modern recordkeeping began
(via sciencedaily.com) Earth's global average surface temperature in 2021 tied with 2018 as the sixth warmest on record, according to independent analyses done by NASA and NOAA. Collectively, the past eight years are the warmest years since modern recordkeeping began in 1880.
Published New insights into sea ice and climate change
(via sciencedaily.com) A 170 m record of marine sediment cores extracted from Adélie Land in Antarctica is yielding new insights into the complicated relationship between sea ice and climate change.
Published New study ties solar variability to the onset of decadal La Nina events
(via sciencedaily.com) A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.
Published Antarctic seals reveal worrying threats to disappearing glaciers
(via sciencedaily.com) More Antarctic meltwater is surfacing than was previously known, modifying the climate, preventing sea ice from forming and boosting marine productivity- according to new research. For the first time, researchers have been able to obtain full-depth glacial meltwater observations in winter, using instruments attached to the heads of seals living near the Pine Island Glacier, in the remote Amundsen Sea in the west of Antarctica.
Published Researchers use car collisions with deer to study mysterious animal-population phenomena
(via sciencedaily.com) By parsing data on weather, deer populations and deer-vehicle collisions in Wisconsin, investigators show spatial synchrony could be driving population cycles, rather than the reverse.
Published 2020 tied for warmest year on record, NASA analysis shows
(via sciencedaily.com) Earth's global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.
Published Largest study of Asia's rivers unearths 800 years of paleoclimate patterns
(via sciencedaily.com) The SUTD study will be crucial for assessing future climatic changes and making more informed water management decisions.
Published Previously undescribed lineage of Archaea illuminates microbial evolution
(via sciencedaily.com) Scientists describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation.
Published How new data can make ecological forecasts as good as weather forecasts
(via sciencedaily.com) Soon, ecologists thinks we'll be able to pull off the same forecasting feat for bird migrations and wildlife populations as for climate forecasts. That's because just as those recurring changes in climate have predictable consequences for humans, they also have predictable effects on plants and animals.
Published Improved estimates of Brazilian Amazon gains and losses
(via sciencedaily.com) A new study generated improved annual maps of tropical forest cover in the Brazilian Amazon in 2000-2017 and provided better characterization on the spatio-temporal dynamics of forest area, loss and gain in this region. The Amazon basin has the largest tropical forests in the world. Rapid changes in land use, climate and other human activities have resulted in substantial deforestation in the Brazilian Amazon over the past several decades.
