The age and sedimentary environment of the Silurian “Lower Red Beds” (LRBs)， which occur widely in South China， have long been controversial because of the scarcity of index fossils. Recently， these beds have been dated by trilobites as middle-late Aeronian to early Telychian in age. Here， we report abundant brachiopods from the LRBs in Wuhan， Middle yangtze Region， including atrypides (Meifodia hunanensis， Zygospiraella sp. 1， Zygospiraella sp. 2 and Nalivkinia? sp.)， spiriferides (Striispirifer acuminiplicatus， Striispirifer? sp.)， strophomenides (Eostropheodonta? sp. and Katastrophomena modesta)， and linguliformeans (Anomaloglossa? sp. and Orbiculoidea? sp.). Most of these are common in the Leijiatun， Xiangshuyuan， Shihniulan， Niuchang， Lojoping， and Shamao formations in the Upper yangtze Region. The discovery of brachiopods from the LRBs in Wuhan not only enrich the biodiversity of the LRBs in the yangtze Region， where Meifodia， Zygospiraella， Katastrophomena and Eostropheodonta are first found in the LRBs， but also expand the paleogeographical distribution of brachiopods to Middle-Lower yangtze Region that first radiated after the end-Ordovician extinction. In addition， this brachiopod fauna also provides important implications for the sedimentary environment of LRBs during the Llandovery， which is usually developed in the nearshore shallow-water (BA1-2)， althought this paper extends to the deeper parts of the shallow-marine (BA3-4).

The concentration difference in the near-surface region of lithium metal is the main cause of lithium dendrite *** this issue will be key to achieving high-performance lithium metal batteries(LMBs).Herein,we construct a lithium nitrate(LiNO_(3))-implanted electroactiveβphase polyvinylidene fluoride-co-hexafluoropropylene(PVDF-HFP)crystalline polymorph layer(PHL).The electronegatively charged polymer chains attain lithium ions on the surface to form lithium-ion charged *** channels act as reservoirs to sustainably release Li ions to recompense the ionic flux of electrolytes,decreasing the growth of lithium *** stretched molecular channels can also accelerate the transport of Li *** combined effects enable a high Coulombic efficiency of 97.0%for 250 cycles in lithium(Li)||copper(Cu)cell and a stable symmetric plating/stripping behavior over 2000 h at 3 mA cm^(-2)with ultrahigh Li utilization of 50%.Furthermore,the full cell coupled with PHL-Cu@Li anode and Li Fe PO_(4) cathode exhibits long-term cycle stability with high-capacity retention of 95.9%after 900 ***,the full cell paired with LiNi_(0.87)Co_(0.1)Mn_(0.03)O_(2)maintains a discharge capacity of 170.0 mAh g^(-1)with a capacity retention of 84.3%after 100 cycles even under harsh condition of ultralow N/P ratio of *** facile strategy will widen the potential application of LiNO_(3)in ester-based electrolyte for practical high-voltage LMBs.

混凝土易受硫酸盐和氯盐的耦合侵蚀,且常伴随钙溶蚀作用,会产生严重的耐久性问题。为探明耦合侵蚀工况下混凝土的劣化机理,建立了一套基于化学反应的多离子耦合侵蚀模型,并通过第三方试验验证了模型的可靠性。本模型能够基于不同的初始材料参数和外界离子浓度预测出物质传输和产物分布情况,通过离子渗透深度、时变扩散系数和产物含量等指标研判混凝土劣化进程。同时,模型通过综合考虑钙溶蚀、硫酸盐侵蚀和氯盐侵蚀三者之间的耦合作用揭示了复杂环境因素对混凝土劣化过程的影响。研究发现短期内硫-氯间的耦合作用会抑制2种盐类的侵蚀,而忽略钙溶蚀作用会导致混凝土内部生成的钙矾石量减少但分布更广。基于该模型进一步探讨了环境/材料变量对硫-氯耦合侵蚀的影响,为预防硫-氯耦合侵蚀下混凝土耐久性问题提供理论参考。
