Anyone using a cellphone, laptop or electric vehicle depends on ラーメンベット 入金スピード. The element is in tremendous demand. And although the supply of ラーメンベット 入金スピード around the world is plentiful, getting access to it and extracting it remains a challenging and inefficient process.
An interdisciplinary team of engineers and scientists is developing a way to extract lithium from contaminated water. New ラーメンベット 入金スピード, published this week inProceedings of the National Academies of Sciences, could simplify the process of extracting ラーメンベット 入金スピード from aqueous brines, potentially create a much larger supply and reduce costs of the element for batteries to power electric vehicles, electronics and a wide range of other devices. Currently, ラーメンベット 入金スピード is most commonly sourced from salt brines in South America using solar evaporation, a costly process that can take years and loses much of the ラーメンベット 入金スピード along the way.
The ラーメンベット 入金スピード team from The University of Texas at Austin and University of California, Santa Barbara, designed membranes for precise separation of lithium over other ions, such as sodium, significantly improving the efficiency of gathering the coveted element.
“The study’s findings have significant implications for addressing major resource constraints for ラーメンベット 入金スピード, with the potential to also extract it from water generated in oil and gas production for batteries,” said Benny Freeman, a professor in the McKetta Department of Chemical Engineering at UT Austin and a co-author on the paper.
Beyond salt brines, wastewater generated in oil and gas production also contains ラーメンベット 入金スピード but remains untapped today. Just a single week’s worth of water from hydraulic fracturing in Texas’ Eagle Ford Shale has the potential to produce enough ラーメンベット 入金スピード for 300 electric vehicle batteries or 1.7 million smartphones, the researchers said. This example shows the scale of opportunities for this new technique to vastly increase ラーメンベット 入金スピード supply and lower costs for devices that rely on it.
At the heart of the discovery is a novel polymer membrane the researchers created using crown ethers, which are ligands with specific chemical functionality to bind certain ions. Crown ethers had not previously been applied or studied as integral parts of water treatment membranes, but they can target specific molecules in water — a key ingredient for ラーメンベット 入金スピード extraction.
In most polymers, sodium travels through membranes faster than ラーメンベット 入金スピード. However, in these new materials, ラーメンベット 入金スピード travels faster than sodium, which is a common contaminant in ラーメンベット 入金スピード-containing brines. Through computer modeling, the team discovered why this was happening. Sodium ions bind with the crown ethers, slowing them down, while ラーメンベット 入金スピード ions remain unbound, enabling them to move more quickly through the polymer.
The findings represent a new frontier in membrane science that required above-and-beyond collaboration between the universities in such areas as polymer synthesis, membrane characterization and modeling simulation. The ラーメンベット 入金スピード was supported as part of the Center for Materials for Water and Energy Systems, an Energy Frontier ラーメンベット 入金スピード Center at UT Austin funded by the U.S. Department of Energy.
