Unlocking the potential of lithium-ion batteries with advanced binders      (via sciencedaily.com)     Original source 

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.

Lithium-ion batteries from drones might find second lives in less 'stressful' devices      (via sciencedaily.com)     Original source 

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.

Mercury rising: Study sheds new light on ancient volcanoes' environmental impact      (via sciencedaily.com)     Original source 

Massive volcanic events in Earth's history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and mass extinctions. A new method to estimate how much and how rapidly carbon was released by the volcanoes could improve our understanding of the climate response, according to an international team.

80 mph speed record for glacier fracture helps reveal the physics of ice sheet collapse      (via sciencedaily.com)     Original source 

New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. A 6.5-mile crack formed in 2012 over 5-and-a-half minutes, showing that ice shelves can effectively shatter -- though the speed is limited by seawater rushing in. The results help inform large-scale ice sheet models and projections of future sea level rise.

UBC Okanagan researchers look to the past to improve construction sustainability      (via sciencedaily.com)     Original source 

Researchers are revisiting old building practices -- the use of by-products and cast-offs -- as a way to improve building materials and sustainability of the trade. A technique known as rammed earth construction uses materials that are alternatives to cement and are often more readily available in the environment. One such alternative is wood fly ash, a by-product of pulp mills and coal-fired power plants.

A new vibrant blue pottery pigment with less cobalt      (via sciencedaily.com)     Original source 

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.

Biggest Holocene volcano eruption found by seabed survey      (via sciencedaily.com)     Original source 

A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.

New water batteries stay cool under pressure      (via sciencedaily.com)     Original source 

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.

Road to better performing batteries using less critical raw materials      (via sciencedaily.com)     Original source 

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.

Discovery of new Li ion conductor unlocks new direction for sustainable batteries      (via sciencedaily.com)     Original source 

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.

Early-stage subduction invasion      (via sciencedaily.com)     Original source 

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in what is known as the Wilson cycle.

New 'time travel' study reveals future impact of climate change on coastal marshes      (via sciencedaily.com)     Original source 

A new study offers a glimpse into the possible impact of climate change on coastal wetlands 50 years or longer into the future. Scientists are usually forced to rely on computer models to project the long-term effects of rising seas, but an unexpected set of circumstances enabled a real-world experiment along the Gulf Coast.

Researchers studying ocean transform faults, describe a previously unknown part of the geological carbon cycle      (via sciencedaily.com)     Original source 

This study reports widespread mineral carbonation of mantle rocks in an oceanic transform fueled by magmatic degassing of CO2. The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. The confluence of tectonically exhumed mantle rocks and CO2-rich alkaline basalt formed through limited extents of melting characteristic of the St. Paul's transform faults may be a pervasive feature at oceanic transform faults in general. Because transform faults have not been accounted for in previous estimates of global geological CO2 fluxes, the mass transfer of magmatic CO2 to the altered oceanic mantle and seawater may be larger than previously thought.

Ice cores provide first documentation of rapid Antarctic ice loss in the past      (via sciencedaily.com)     Original source 

Researchers have uncovered the first direct evidence that the West Antarctic Ice Sheet shrunk suddenly and dramatically at the end of the Last Ice Age, around eight thousand years ago. The evidence, contained within an ice core, shows that in one location the ice sheet thinned by 450 meters -- that's more than the height of the Empire State Building -- in just under 200 years.
