Published 'The magic of making electricity from metals and air' The vexing carbonate has achieved it!
(via sciencedaily.com) Original source Team develops a high-energy, high-efficiency all-solid-state Na-air battery platform.
Published Imperceptible sensors made from 'electronic spider silk' can be printed directly on human skin
(via sciencedaily.com) Original source Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that's a finger or a flower petal.
Published Renewable grid: Recovering electricity from heat storage hits 44% efficiency
(via sciencedaily.com) Original source Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to new research.
Published AI poised to usher in new level of concierge services to the public
(via sciencedaily.com) Original source Concierge services built on artificial intelligence have the potential to improve how hotels and other service businesses interact with customers, a new paper suggests.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds
(via sciencedaily.com) Original source Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published New milestone for lithium metal batteries
(via sciencedaily.com) Original source Scientists develop a porous structures for lithium metal batteries.
Published Finding the beat of collective animal motion
(via sciencedaily.com) Original source Virtual Reality experiments have illuminated the rhythmic glue that could keep animals moving in synchrony.
Published Batteries: Modeling tomorrow's materials today
(via sciencedaily.com) Original source Which factors determine how quickly a battery can be charged? Microstructural models have helped researchers discover and investigate new electrode materials. When sodium-nickel-manganese oxide is used as cathode material in sodium-ion batteries, simulations reveal modifications of the crystal structure during charging. These modifications lead to an elastic deformation, as a result of which capacity decreases.
Published Building a better sarcasm detector
(via sciencedaily.com) Original source Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools. So researchers have now developed a multimodal algorithm for improved sarcasm detection that examines multiple aspects of audio recordings for increased accuracy. They used two complementary approaches -- sentiment analysis using text and emotion recognition using audio -- for a more complete picture.
Published Carbon-capture batteries developed to store renewable energy, help climate
(via sciencedaily.com) Original source Researchers are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide. Researchers recently created and tested two different formulations for batteries that store renewable energy; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products.
Published Making batteries takes a lot of lithium: Some could come from gas well wastewater
(via sciencedaily.com) Original source A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Published Virtual reality becomes more engaging when designers use cinematic tools
(via sciencedaily.com) Original source Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published Eco-friendly and affordable battery for low-income countries
(via sciencedaily.com) Original source A battery made from zinc and lignin that can be used over 8000 times. This has been developed with a vision to provide a cheap and sustainable battery solution for countries where access to electricity is limited.
Published Disorder improves battery life
(via sciencedaily.com) Original source What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team has discovered that local disorder in the oxide cathode material increases the number of times Li-ion batteries can be charged and discharged.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be
(via sciencedaily.com) Original source New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Biomechanical dataset for badminton performance analysis
(via sciencedaily.com) Original source In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.
