The high‐polarity β‐phase poly(vinylidene difluoride) (β‐PVDF), which has all trans conformation with F and H atoms located on the opposite sides of the polymer backbone, is demonstrated to be a promising artificial solid‐electrolyte interphase coating on both Cu and Li metal anodes for dendrite‐free Li deposition/stripping and enhanced cycling performance. A thin (≈4 µm) β‐PVDF coating on Cu enables uniform Li deposition/stripping at high current densities up to 5 mA cm?2, Li‐plating capacity loadings of up to 4 mAh cm?2, and excellent cycling stability over hundreds of cycles under practical conditions (1 mA cm?2 with 2 mAh cm?2). Full cells containing an LiFePO4 cathode and an anode of either β‐PVDF coated Cu or Li also exhibit excellent cycling stability. The profound effects of the high‐polarity PVDF coating on dendrite suppression are attributed to the electronegative F‐rich interface that favors layer‐by‐layer Li deposition. This study offers a new strategy for the development of dendrite‐free metal anode technology. 相似文献

A multi‐gene (SSU, LSU, psbA, and COI) molecular phylogeny of the family Corallinaceae (excluding the subfamilies Lithophylloideae and Corallinoideae) showed a paraphyletic grouping of six monophyletic clades. Pneophyllum and Spongites were reassessed and recircumscribed using DNA sequence data integrated with morpho‐anatomical comparisons of type material and recently collected specimens. We propose Chamberlainoideae subfam. nov., including the type genus Chamberlainium gen. nov., with C. tumidum comb. nov. as the generitype, and Pneophyllum. Chamberlainium is established to include several taxa previously ascribed to Spongites, the generitype of which currently resides in Neogoniolithoideae. Additionally we propose two new genera, Dawsoniolithon gen. nov. (Metagoniolithoideae), with D. conicum comb. nov. as the generitype and Parvicellularium gen. nov. (subfamily incertae sedis), with P. leonardi sp. nov. as the generitype. Chamberlainoideae has no diagnostic morpho‐anatomical features that enable one to assign specimens to it without DNA sequence data, and it is the first subfamily to possess both Type 1 (Chamberlainium) and Type 2 (Pneophyllum) tetra/bisporangial conceptacle roof development. Two characters distinguish Chamberlainium from Spongites: tetra/biasporangial conceptacle chamber diameter (<300 μm in Chamberlainium vs. >300 μm in Spongites) and tetra/bisporangial conceptacle roof thickness (<8 cells in Chamberlainium vs. >8 cells in Spongites). Two characters also distinguish Pneophyllum from Dawsoniolithon: tetra/bisporangial conceptacle roof thickness (<8 cells in Pneophyllum vs. >8 cells in Dawsoniolithon) and thallus construction (dimerous in Pneophyllum vs. monomerous in Dawsoniolithon). 相似文献

The effect of protriptyline on Ca2+ physiology in human hepatoma is unclear. This study explored the effect of protriptyline on [Ca2+]i and cytotoxicity in HepG2 human hepatoma cells. Protriptyline (50–150 μM) evoked [Ca2+]i rises. The Ca2+ entry was inhibited by removal of Ca2+. Protriptyline‐induced Ca2+ entry was confirmed by Mn2+‐induced quench of fura‐2 fluorescence. Except nifedipine, econazole, SKF96365, GF109203X, and phorbol 12‐myristate 13 acetate did not inhibit Ca2+ entry. Treatment with the endoplasmic reticulum Ca2+ pump inhibitor 2,5‐di‐tert‐butylhydroquinone (BHQ) inhibited 40% of protriptyline‐induced response. Treatment with protriptyline abolished BHQ‐induced response. Inhibition of phospholipase C (PLC) suppressed protriptyline‐evoked response by 70%. At 20–40 μM, protriptyline killed cells which was not reversed by the Ca2+ chelator 1,2‐bis(2‐aminophenoxy)ethane‐N,N,N′,N′‐tetraacetic acid‐acetoxymethyl ester (BAPTA/AM). Together, in HepG2 cells, protriptyline induced [Ca2+]i rises that involved Ca2+ entry through nifedipine‐sensitive Ca2+ channels and PLC‐dependent Ca2+ release from endoplasmic reticulum. Protriptyline induced Ca2+‐independent cell death. 相似文献
