An ultrastable lithium metal anode enabled by designed metal fluoride spansules by Yuan, Huadong, Nai, Jianwei, Tian, He, Ju, Zhijin, Zhang, Wenkui, Liu, Yujing, Tao, Xinyong, Lou, David Xiong Wen

“…Here, we design “spansules” made of NaMg(Mn)F3@C core@shell microstructures as the matrix for the LMA, which can offer a long-lasting release of functional ions into the electrolyte. By the assistance of cryogenic transmission electron microscopy, we reveal that an in situ–formed metal layer and a unique LiF-involved bilayer structure on the Li/electrolyte interface would be beneficial for effectively suppressing the growth of lithium dendrites. …”

Sorptive properties of biofilm matrix for heavy metal sequestering by Elisa Tiaras

“…This is preliminary result that indicates that Pel and Psl polysaccharides do have impacts on the biofilms ability to interact with and thus, treat toxic metal ions. Despite polysaccharide quantification and protein quantification that did not indicate significant differences between the 4 strains, further findings from proteomics analysis may provide a greater insight to how Pel and Psl affect the biofilm.…”
