Published Efficient sodium-ion battery anode for energy storage
(via sciencedaily.com) Lithium is expensive and limited, necessitating the development of efficient energy storage systems beyond lithium-ion batteries. Sodium is a promising candidate. However, sodium ions, being large and sluggish, hamper sodium-ion battery (SIB) anode performance. Researchers have recently developed pyrolyzed quinacridones, new carbonaceous SIB anode materials, that are efficient, easily prepared, and exhibit excellent electrochemical properties, including high sodium-ion storage performance and cycling stability.
Published Development of next-generation solid electrolyte technology, 'stable' even when exposed to the atmosphere
(via sciencedaily.com) Engineers have announced the development of solid electrolytes with enhanced atmospheric stability.
Published The other paleo diet: Rare discovery of dinosaur remains preserved with its last meal
(via sciencedaily.com) Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.
Published What the inner ear of Europasaurus reveals about its life
(via sciencedaily.com) Europasaurus is a long-necked, herbivorous dinosaur that lived in the Late Jurassic, about 154 million years ago, on a small island in modern-day Germany. Recently, scientists examined fossil braincase material of Europasaurus with the aid of micro-computed tomography (micro-CT). The digital reconstruction of the inner ear of Europasaurus gave the researchers new insights not only into its hearing ability, but also into its reproductive and social behavior.
Published Designing better battery electrolytes
(via sciencedaily.com) Scientists give the lay of the land in the quest for electrolytes that could enable revolutionary battery chemistries.
Published Scientists discover what was on the menu of the first dinosaurs
(via sciencedaily.com) The earliest dinosaurs included carnivorous, omnivorous and herbivorous species, according to a team of palaeobiologists.
Published Climate change played key role in dinosaur success story
(via sciencedaily.com) Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods.
Published Ingestible biobatteries could allow new view of digestive system
(via sciencedaily.com) A new biobattery could power ingestible cameras in the small intestine.
Published New life flashed into lithium-ion anodes
(via sciencedaily.com) Chemists use flash Joule heating to recover graphite anodes from spent lithium-ion batteries at a cost of about $118 per ton.
Published Dinosaur teeth reveal what they didn't eat
(via sciencedaily.com) Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis (DMTA) has now been used to infer the feeding habits of large theropods, including Allosaurus and T. rex. By taking 3D images of individual teeth and analyzing the pattern of marks scratched into them, researchers could reason which dinosaurs may have frequently crunched on hard bone and which may have regularly eaten softer foods and prey. This technique opens up a new avenue of research for paleontology, helping us to better understand not only dinosaurs themselves but also the environment and communities in which they lived.
Published Flameproofing lithium-ion batteries with salt
(via sciencedaily.com) A polymer-based electrolyte makes for batteries that keep working -- and don't catch fire -- when heated to over 140 degrees F.
Published Dinosaurs were on the up before asteroid downfall
(via sciencedaily.com) Dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago, a landmark study reveals. Fresh insights into dinosaurs' ecosystems -- the habitats and food types that supported their lives -- suggests that their environments were robust and thriving, right up until that fateful day, at the end of the Cretaceous period.
Published New battery technology has potential to significantly reduce energy storage costs
(via sciencedaily.com) Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonized economy.
Published Ankylosaurs battled each other as much as they fought off T. rex
(via sciencedaily.com) Scientists have found new evidence for how armored dinosaurs used their iconic tail clubs. The exceptional fossil of the ankylosaur Zuul crurivastator has spikes along its flanks that were broken and re-healed while the dinosaur was alive -- injuries that the scientists think were caused from a strike by another Zuul's massive tail club. This suggests ankylosaurs had complex behavior, possibly battling for social and territorial dominance or even engaging in a 'rutting' season for mates.
Published X-rays reveal elusive chemistry for better EV batteries
(via sciencedaily.com) Scientists used high energy x-rays to investigate the solid-electrolyte interphase, a chemical layer in batteries that's key to stabilizing lithium metal anodes. Chemists unraveled this complex chemical mechanisms that is crucial for boosting energy density.
Published New manufacturing process produces better, cheaper cathodes for lithium-ion batteries
(via sciencedaily.com) Researchers have developed a new method for producing a key component of lithium-ion batteries. The result is a more affordable battery from a faster, less wasteful process that uses less toxic material.
Published A self-powered ingestible sensor opens new avenues for gut research
(via sciencedaily.com) Engineering researchers have developed a battery-free, pill-shaped ingestible biosensing system designed to provide continuous monitoring in the intestinal environment. It gives scientists the ability to monitor gut metabolites in real time, which wasn't possible before. This could unlock a new understanding of intestinal metabolite composition, which significantly impacts human health overall.
Published Stabilizing lithium-ion batteries with microbially synthesized electrolyte additive
(via sciencedaily.com) Lithium-ion batteries with high-energy-density cathodes are necessary to meet the energy demands of next-generation electronics and electric vehicles. At high voltages, however, the battery electrolyte undergoes excessive decomposition, compromising cathode performance. To tackle this, researchers have now synthesized a bio-based, non-toxic additive material that stabilizes the cathode by forming a passivation layer on its surface and suppressing its decomposition. Eco-friendly and low-cost, the novel compound could promote a wider utilization of bio-based resources.
Published Fossil overturns more than a century of knowledge about the origin of modern birds
(via sciencedaily.com) Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.
Published Oldest Pterodactylus fossil found in Germany
(via sciencedaily.com) The oldest Pterodactylus specimen was found near Painten, Germany. The fossil is about one million years older than other Pterodactylus specimens. The specimen is a complete, well-preserved skeleton of a small-sized individual. With a 5-cm-long skull, it represents a rare 'sub-adult' individual.
