3D lithiophilic skeletons have attracted enormous attention in homogenizing local current distribution and optimizing metal deposition in the pursuit of robust Li metal anodes. Nonetheless, their practicability is markedly plagued by the cumbersome production routes and mediocre Coulombic efficiency (CE) of Li plating/stripping. Herein, scalable in situ growth of uniform bismuthene arrays over commercial Cu foam via spontaneous galvanic replacement reaction is demonstrated. Exhaustive structural/electrochemical measurements in combination with theoretical calculations collectively disclose the reversible plating‐alloying mechanism, wherein the formed Li3Bi alloy interphase aids to lower the Li nucleation overpotential and elevate the CE performance. The thus‐designed Li metal electrode sustains a stable cyclic operation at 1 mA cm−2/1 mAh cm−2 for 1600 h. When paired with LiFePO4 and sulfur cathodes, the Li metal batteries enable gratifying rate capability and cycling durability. This straightforward maneuver opens a new frontier in the scalable manufacturing of pragmatic current collectors in an economic fashion.

Abstract Constructing a conductive carbon‐based artificial interphase layer (AIL) to inhibit dendritic formation and side reaction plays a pivotal role in achieving longevous Zn anodes. Distinct from the previously reported carbonaceous overlayers with singular dopants and thick foreign coatings, a new type of N/O co‐doped carbon skin with ultrathin feature (i.e., 20 nm thickness) is developed via the direct chemical vapor deposition growth over Zn foil. Throughout fine‐tuning the growth conditions, mosaic nanocrystalline graphene can be obtained, which is proven crucial to enable the orientational deposition along Zn (002), thereby inducing a planar Zn texture. Moreover, the abundant heteroatoms help reduce the solvation energy and accelerate the reaction kinetics. As a result, dendrite growth, hydrogen evolution, and side reactions are concurrently mitigated. Symmetric cell harvests durable electrochemical cycling of 3040 h at 1.0 mA cm−2/1.0 mAh cm−2 and 136 h at 30.0 mA cm−2/30.0 mAh cm−2. Assembled full battery further realizes elongated lifespans under stringent conditions of fast charging, bending operation, and low N/P ratio. This strategy opens up a new avenue for the in situ construction of conductive AIL toward pragmatic Zn anode.

Li metal is regarded as one of the most promising anodes for next‐generation rechargeable batteries. Nonetheless, infinite volume change and severe dendrite growth impede its practicability. To date, unremitting efforts have been devoted to stabilizing Li metal anode via the rational design of 3D current collectors. In this sense, optimizing Li nucleation behavior plays a pivotal role in alleviating the dendrite formation. Herein, a practically viable route is devised by in situ crafting lithiophilic CuSe granules on the dealloyed Cu skeleton (D‐Cu@CuSe). Persuasive electrochemical analysis and systematic theoretical calculation disclose the underlying Li nucleation mechanism on the CuSe overlayer. Impressively, the D‐Cu@CuSe‐Li symmetric cell can sustain a stable plating/stripping operation over 1000 h at a high depth of discharge at 62.5%. More crucially, when paired with high‐loading sulfur cathodes, D‐Cu@CuSe‐Li||S batteries harvest advanced areal capacity and stable cycling performance even under stringent working conditions of low negative‐to‐positive (N/P) (≈2) and electrolyte‐to‐sulfur (8 μL mgs−1) ratios. Overall, a fresh perspective into rationalizing current collector design is afforded, which extends Li utilization and cycling durability in the pursuit of pragmatic Li metal anodes.

Metallic zinc shows great promise as an anode material in aqueous rechargeable batteries owing to its high theoretical capacity, excellent safety, and low cost. However, the practical utilization of zinc metal anodes faces challenges due to significant side reactions with the aqueous electrolyte and the prevalent growth of dendrites at the interface between the electrode and electrolyte. In this study, succinic acid (SA) has been investigated as a functional additive to tackle these issues. The SA additive can effectively mitigate side reactions and promote the uniform deposition of Zn by reducing the electrostatic potential of the Znion solvation structure and preferentially adsorb on the surface of the Zn anode. Consequently, symmetric Zn//Zn cells with the SA additive exhibit remarkable cycling stability over 650 hours with a depth of discharge of 51%. The asymmetric Zn//Cu cells display a cycling efficiency as high as 99.7% over 1300 cycles at 1 mA cm−2 and 1 mA h cm−2 . Additionally, compared to the electrolytes without additives, the developed electrolyte with SA shows a significant enhancement in the cycling performance of a Zn–KMnO full cell.

The article presents an overview of the history and current status of nuclear transfer cloning. It states that in the early 1900s, some of the earliest research that created clones was carried out by Hans Spemann, a great developmental biologist. Spemann found that he was able to produce twins by dissecting newt embryos up to the early gastrula stage. One of the potential advantages of cloning research is that it is expected to produce high-genetic-value agricultural animals for developing countries.

To enrich the flavor and enhance the quality of crown pear wine, Saccharomyces cerevisiae (Sc) and Torulaspora delbrueckii (Td) were selected for co-culture. Changes in the phenolic composition and antioxidant activity of crown pear wine were investigated during single and mixed yeast fermentation and the correlation between them was investigated. Besides, the organic acid and volatile compounds of the two wines were compared. The results showed that the contents of total polyphenols (TP) and total flavonoids (TF) in pear wine increased first and then decreased during fermentation, and so did the scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. Compared with pure Sc, the contents of TP and TF in the co-fermented wine increased significantly by 16.5% and 15.9%, respectively. The DPPH radical scavenging capacity significantly increased by 8.3% and the total acid content decreased by 10.05%, with malic acid being the major one. The predominant phenolic compounds in pear wine were arbutin, chlorogenic acid and catechin, whose contents changed in a complex manner during the fermentation process. The phenolic profiles of the two samples were different. Pearson correlation coefficients showed that there was a strongly positive correlation between the DPPH radical scavenging capacity and the contents of TP, arbutin and epicatechin (P < 0.01). The co-fermented wine had higher concentrations of volatile compounds, especially acetate esters contributing to fruity aroma, compared with that obtained with pure Sc. Overall, mixed fermentation of Sc with Td can improve the quality and flavor intensity of crown pear wine. This study provides a support for the deep-processing of crown pear.
