Metal nanoparticles supported on a nonconductive oxide undergo pH-dependent spontaneous polarization by Wesley, Thejas S, Hülsey, Max J, Westendorff, Karl S, Lewis, Noah B, Crumlin, Ethan J, Román-Leshkov, Yuriy, Surendranath, Yogesh

“…Electrochemical polarization, which often plays a critical role in driving chemical reactions at solid–liquid interfaces, can arise spontaneously through the exchange of ions and/or electrons across the interface. However, the extent to which such spontaneous polarization prevails at nonconductive interfaces remains unclear because such materials preclude measuring and controlling the degree of interfacial polarization via standard (i.e., wired) potentiometric methods. …”

Electric field induced associations in the double layer of salt-in-ionic-liquid electrolytes by Markiewitz, Daniel M, Goodwin, Zachary AH, McEldrew, Michael, Pedro de Souza, J, Zhang, Xuhui, Espinosa-Marzal, Rosa M, Bazant, Martin Z

“…Here, we develop a theory for the electrical double layer (EDL) of SiILs where we consistently account for the thermoreversible association of ions into Cayley tree aggregates. The theory predicts that the IL cations first populate the EDL at negative voltages, as they are not strongly bound to the anions. …”

Construction of a stable lithium sulfide membrane to greatly confine polysulfides for high performance lithium – sulfur batteries by Wu, Chao, Guo, Chunxian, Wu, JingGao, Ai, Wei, Yu, Ting, Li, Chang Ming

“…The membrane offers unique and selective channels which allow only ions/small sulfides to pass through and confine polysulfide transport, restricting the shuttle effect, and thus providing a large capacity of 685 mA h g−1 at 1C and a long-lasting cycling stability (0.03% capacity decay per cycle). …”

Generating new cross‐relaxation pathways by coating prussian blue on NaNdF4 to fabricate enhanced photothermal agents by Yu, Zhongzheng, Hu, Wenbo, Zhao, Hui, Miao, Xiaofei, Guan, Yan, Cai, Weizheng, Zeng, Zhiping, Fan, Quli, Tan, Timothy Thatt Yang

“…Herein, we coated Prussian blue (PB) on NaNdF4 nanoparticles to fabricate core-shell nanocomplexes with new cross relaxation pathways between the ladder-like energy levels of Nd3+ ions and continuous energy band of PB. The photothermal conversion efficiency was improved exceptionally and the mechanism of the enhanced photothermal effect was investigated. …”
