Published New all-liquid iron flow battery for grid energy storage



A new iron-based aqueous flow battery shows promise for grid energy storage applications.
Published Unintended consequences of fire suppression



A new study reveals how fire suppression ensures that wildfires will burn under extreme conditions at high severity, exacerbating the impacts of climate change and fuel accumulation.
Published Crawfish could transfer ionic lithium from their environment into food chain



Lithium-ion rechargeable batteries are showing up in ever more devices, and the increasing use of this technology means more lithium is expected to find its way into the environment as a contaminant. In new research, a team has explored how this ion accumulates in a common Southern crustacean, the crawfish, with implications for the environment and public health.
Published Fast-charging lithium-sulphur batteries on the horizon



New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.
Published Revolutionary method developed for mass-producing polymer solid electrolytes



Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.
Published Batteries for airborne electric vehicles that take off and land vertically



Researchers are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically. Researchers are developing new energy-dense materials, learning how these materials degrade under extreme conditions, and developing battery control systems.
Published Healable cathode could unlock potential of solid-state lithium-sulfur batteries



Engineers developed a cathode material for lithium-sulfur (Li-S) batteries that is healable and highly conductive, overcoming longstanding challenges of traditional sulfur cathodes. The advance holds promise for bringing more energy dense and low-cost Li-S batteries closer to market.
Published 2020 extreme weather event that brought fires and snow to western US



The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event.
Published Unlocking the potential of lithium-ion batteries with advanced binders



Lithium-ion batteries employ binders that encounter challenges such as poor conductivity and expansion during charging. In a recent study, scientists have developed a high-performing binder using poly(vinylphosphonic acid) for silicon oxide-based anodes in lithium-ion batteries. This binder offers enhanced performance as demonstrated by the superior durability, and discharging capacity of the anodes compared to conventional options. With patents filed internationally, this technology holds promise for broader applications in electric vehicles and beyond.
Published Lithium-ion batteries from drones might find second lives in less 'stressful' devices



Taking flight can be stressful -- especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device's overall lifespan. Research shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the 'stressed out' batteries could also have second lives in less strenuous applications.
Published Study finds drought fuels invasive species after wildfires



Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Published Imaging grain boundaries that impede lithium-ion migration in solid-state batteries



A research team has developed a new technique to image grain boundaries obstructing lithium-ion migration in solid-state batteries -- a promising type of next-generation battery.
Published Cooler, wetter parts of Pacific Northwest likely to see more fires, new simulations predict



Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier.
Published A new vibrant blue pottery pigment with less cobalt



Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.
Published New water batteries stay cool under pressure



A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.
Published Road to better performing batteries using less critical raw materials



Researchers are developing batteries that can charge faster, offer more stable storage and are made of sustainable materials that are widely available. In doing so, they offer a cheaper alternative to lithium-ion batteries that consist of rare materials and have a high CO2 -footprint.
Published Wildfires linked to surge in mental health-related emergency department visits



A new studyshows wildfires lead to an increase of anxiety-related emergency department visits in the western United States, amplifying the concerning parallel trajectory of two escalating public health crises -- mental health and climate change.
Published Discovery of new Li ion conductor unlocks new direction for sustainable batteries



Researchers have discovered a solid material that rapidly conducts lithium ions. Consisting of non-toxic earth-abundant elements, the new material has high enough Li ion conductivity to replace the liquid electrolytes in current Li ion battery technology, improving safety and energy capacity. The research team have synthesized the material in the laboratory, determined its structure and demonstrated it in a battery cell.
Published Greenhouse gas repurposed



Cutting-edge research converted waste carbon dioxide into a potential precursor for chemicals and carbon-free fuel.
Published Smart earrings can monitor a person's temperature



Researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user's earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.
