Abstract

Metal recovery coupled with CO2 mineralization from sustainable sources, such as seawater, has garnered significant attention from environmental science and resource utilization perspectives. Herein, an earth‐abundant and efficient Fe/Fe3C@Fe‐N‐codoped carbon@carbon nanotube (Fe/Fe3C@Fe‐NC@CNT) hybrid cathodic catalyst is introduced for electrochemically extracting magnesium and calcium from desalination brine while capturing CO2 to produce valuable Mg(OH)2 and CaCO3. The Fe/Fe3C@Fe‐NC@CNT, featuring the combination of single‐atomic Fe sites and graphitic layer‐wrapped Fe/Fe3C nanoparticles encapsulated within N‐doped mesoporous carbon tubes, achieves over 90% of Ca2+ and Mg2+ metal cations recovery efficiency at 25 mA cm−2 for 6 h. More importantly, the Fe/Fe3C@Fe‐NC@CNT hybrid catalyst efficiently suppresses the competitive hydrogen evolution side reaction even at high currents and boasts a wider operating potential range compared to benchmark Pt/C, enhancing the metal recovery efficiency and CO2 capture capability. These findings underscore the potential of the Fe/Fe3C@Fe‐NC@CNT hybrid catalyst in revolutionizing brine management and waste stream handling, offering a promising and sustainable solution to these critical environmental challenges.

Abstract

α-Synuclein (α-syn) is important in synucleinopathies such as Parkinson’s disease (PD). While genome-wide association studies (GWASs) of synucleinopathies have identified many risk loci, the underlying genes have not been shown for most loci. Using Drosophila, we screened 3,471 mutant chromosomes for genetic modifiers of α-synuclein and identified 12 genes. Eleven modifiers have human orthologs associated with diseases, including MED13and CDC27, which lie within PD GWAS loci. DrosophilaSkd/Med13 and glycolytic enzymes are co-upregulated by α-syn-associated neurodegeneration. While elevated α-syn compromises mitochondrial function, co-expressing skd/Med13RNAi and α-syn synergistically increase the ratio of oxidized-to-reduced glutathione. The resulting neurodegeneration can be suppressed by overexpressing a glycolytic enzyme or treatment with deferoxamine, suggesting that compensatory glycolysis is neuroprotective. In addition, the functional relationship between α-synuclein, MED13, and glycolytic enzymes is conserved between flies and mice. We propose that hypoxia-inducible factor and MED13 are part of a druggable pathway for PD.
