What if a common element rather than scarce, expensive ones was a key component in electric car batteries?
A collaboration co-led by an Oregon State University chemistry researcher is 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.
The findings, published today in Science Advances, are important for multiple reasons, Oregon State’s Xiulei “David” Ji notes.
The public’s appetite for inexpensive and powerful electronic devices continues to grow. While silicon-based semiconductors have been key to satiating this demand, a superior alternative could be wide-bandgap semiconductors. These materials, which operate at higher temperatures and handle increased power loads, are unfortunately very expensive.
A global team of researchers and industry collaborators led by RMIT University has invented recyclable ‘water batteries’ that won’t catch fire or explode.
Lithium-ion energy storage dominates the market due to its technological maturity, but its suitability for large-scale grid energy storage is limited by safety concerns with the volatile materials inside.
Lead researcher Distinguished Professor Tianyi Ma said their batteries were at the cutting edge of an emerging field of aqueous energy storage devices, with breakthroughs that significantly improve the technology’s performance and lifespan.
The climate transition is a materials transition. Decades of international diplomacy around oil, gas and pipelines are now giving way to conversations around the supply of critical raw materials. And not before time: to meet the EU’s energy and climate targets, we need to build the right technologies, in the right quantities, at the right speed. The problem is that many of these technologies are built with materials imported from just a handful of countries.
Researchers have developed 3D printable conducting polymer hydrogels for implantable bioelectronics, enabling long-term electrophysiological monitoring and modulation of organs.
Researchers at the Karlsruhe Institute of Technology (KIT) introduce a polymer-based material with unique properties in the journal Nature Communications. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future. The research team has successfully tested the material in outdoor tests on the KIT campus.
Recent experimental advancements have enabled more accurate and in-depth analysis of these materials during and after formation. The review article examines two decades of research on the non-classical formation pathways of soft and organic crystalline materials. It details the current theoretical understanding of how these materials form through non-classical pathways, including distinguishing the processes of nucleation and growth across models.
Advances in experimental methods, including in-line scattering/spectroscopy detection, cryo microscopy, and in situ liquid-phase characterization, and their application to studying soft and organic crystalline materials are also discussed.
These experimental techniques have provided strong evidence for non-classical crystallization pathways, leading to key breakthroughs in understanding these processes. However, the sole presence of a specific final product or intermediate does not prove that a material formed via a specific pathway.
Recent research shows that plant-based plastics release far fewer microplastics than traditional plastics in marine environments, suggesting they could be a more environmentally friendly option. However, continued research is crucial to fully assess their impact.
A recent study has discovered that a new plant-based plastic material releases nine times fewer microplastics compared to traditional plastic when subjected to sunlight and seawater. Conducted by researchers from the University of Portsmouth and the Flanders Marine Institute (VLIZ) in Belgium, the study examined the degradation of two different types of plastic under harsh conditions.
A bio-based plastic material made from natural feedstocks held up better when exposed to intense UV light and seawater for 76 days — the equivalent of 24 months of sun exposure in central Europe — than a conventional plastic made from petroleum derivatives.
