Summary: Aqueous zinc-based batteries are expected to be low-cost and high energy density, however, dendrite formation during charging remains a major issue. In situ TEM observations revealed that dendrite growth from the zinc anode causes short-circuiting and cycle degradation in zinc-based batteries. Characterization of electrochemical zinc deposition is crucial for realizing long life rechargeable zinc-based batteries.

Summary: Dendrite-like three-dimensional (3D) MgCo2O4/C nanofibers were synthesized through single-needle electrospinning method and carbonization temperature adjustment. Composed of 1D MgCo2O4/C nanofiber trunks and carbon nanowire/nanotube branches, the diameter of trunks is around 500 nm and that of branches is about 20-40 nm, with lengths ranging from 200-500 nm. The dendrite-like 3D MgCo2O4/C nanofibers exhibit a high specific surface area of 314.027 g/m(2) and excellent electrochemical performance for supercapacitors due to their unique structure.

Summary: This study demonstrates the use of a three-dimensional hierarchical porous copper (3DHP Cu) current collector, derived using an efficient electrochemical dealloying method, to suppress lithium dendrite growth and improve fast electrochemical reaction kinetics. The porous copper surface micropores facilitate lithium ion insertion/extraction, while the interconnected copper network within the structure manages volume changes during lithium plating/stripping. The nanopores on the surface enhance high surface area and even current distribution, leading to stable cycling performance and improved cycle stability in full cells using the 3DHP Cu current collector.

Summary: A three-dimensional N/O-codoped graphene host is synthesized for dendrite-free Zn anodes in Zn-ion batteries. The 3D NOG host exhibits advantages such as limited local current density, low nucleation overpotential, and uniform electric field distribution, facilitating reversible Zn plating/stripping. A Zn@NOG electrode shows excellent cycling stability and dendrite-free behavior, even at a high current density, leading to a considerably improved cycling stability and high coulombic efficiency in the Zn@NOG//MnO2 full battery.

Summary: This study investigates the kinetics of coal char during high temperature gasification using a thermogravimetric analyzer and in situ heating stage microscope. The results show that the random pore model is optimal for fitting the kinetics of coals. The gasification of char is controlled by ash layer diffusion, and the apparent activation energy of the char ranges from 82.27 to 90.74 kJ/mol for Yangchangwan coal and from 89.78 to 91.42 kJ/mol for Shenfu coal. Most char particles participate in gasification via the random pore mode and form amorphous ash. Some particles of Yangchangwan coal char undergo gasification by both homogeneous and shrinking core modes.

Summary: This study evaluated the nutritional status of Omega-3 PUFAs in Chinese elite athletes through dietary intake analysis and serum biomarker detection. The results showed that the intake of EPA + DHA among athletes was lower than recommended, and the serum EPA + DHA levels were also low. Serum EPA + DHA was positively correlated with dietary intake and negatively correlated with inflammatory markers. It is necessary to improve the suboptimal nutritional status of PUFAs in Chinese athletes through dietary intervention.

Summary: Aqueous zinc-ion batteries have received much attention due to their high safety, environmental benignity, and low cost. However, the interface instability issues caused by detrimental side reactions impede their practical applications. In this study, an interface material consisting of a zinc-copper alloy with engineered surfaces is designed to regulate the zinc plating/stripping processes, leading to high-performance aqueous zinc-ion batteries. This work enhances the fundamental understanding of dual-cation intercalation chemistry in aqueous electrochemical systems and provides guidance for exploring high-performance aqueous zinc-ion batteries and beyond.

Summary: In this study, a synergistic strategy was proposed to improve the structural stability and electrochemical performance of the NCM83 cathodes by combining surface polymeric coating with bulk doping using the high-temperature solid-phase method. The results showed successful bulk doping of niobium (Nb), which increased the layer spacing, stabilized the crystal structure, and minimized Li+/Ni2+ mixing. Additionally, a small amount of Nb in the form of oxide and a layer of polyaniline (PANI) were coated on the surface of the NCM83 cathode to prevent electrolyte erosion, inhibit side reactions, and improve Li+ transport coefficient. The optimized NCM83 cathode exhibited outstanding discharge-specific capacity, stable cycling performance, and excellent rate performance, taking advantage of the synergistic effects.

Summary: Reflection interference microscopy enables real-time imaging of the formation and evolution of the solid-electrolyte interphase in batteries, providing valuable insights into its structure and dynamics. The imaging reveals the stratified structure of the interphase, with an inner inorganic layer, an interfacial electrified double layer, and an outer organic-rich layer that is reversible with cycling. The thicknesses of the interphase subcomponents show an inverse correlation, indicating the influence of the inner layer on the formation of the outer layer and lithium nucleation.

Summary: Understanding the nucleation and growth of lithium (Li) is crucial for designing high-performance battery electrodes. However, limited research has been done on the Li nucleation process due to a lack of imaging tools that can provide information on the entire dynamic process. We developed and utilized an operando reflection interference microscope (RIM) to achieve real-time imaging and tracking of Li nucleation dynamics at the individual nanoparticle level. This dynamic and operando imaging platform gives us the essential capabilities to continuously monitor and study the Li nucleation process. Our findings reveal that the formation of initial Li nuclei does not occur at the exact same time, and the Li nucleation process exhibits properties of both progressive and instantaneous nucleation. Furthermore, the RIM allows us to track the growth of individual Li nuclei and extract spatially resolved overpotential maps, which indicate that localized electrochemical environments significantly influence Li nucleation.
