Summary: Liquid metal batteries (LMBs) are being investigated as a potentially inexpensive grid scale energy storage option, but their susceptibility to various instabilities has hindered widespread commercialization. A proposed new structure, the grid structure (GS), has shown promise in suppressing magnetohydrodynamic instabilities in LMBs, improving efficiency. Numerical investigations have confirmed that the specially inserted GS can alter flow field and magnetic field distributions, ultimately enhancing stability and efficiency of LMBs. The GS holds significance for the promotion of grid scale LMBs.

Summary: Ionic liquids combined with TEP or TMP solvents are used to prepare intrinsically safe electrolytes, which effectively solve the problem of dendritic growth and serious interfacial reactions of metallic Zn in conventional electrolytes. The blends of TEP/TMP with an IL fraction of approximately 25 wt% are found to be promising electrolytes, with comparable ionic conductivities to standard phosphate-based electrolytes and significantly improved electrochemical stabilities, achieving continuous operation for over 1000 hours (2.0 mA cm(-2)) and approximately 350 hours (5.0 mA cm(-2)) with a large areal capacity of 10 mAh cm(-2). The use of functionalized IL enhances Zn2+ transport and reduces interfacial resistance, resulting in spongy-like highly porous, homogeneous, and dendrite-free zinc as an anode material.

Summary: A delayed nucleation strategy is proposed to improve the performance of Zn anodes in aqueous Zn-ion batteries. Through a liquid metal (LM) interlayer, the reduction and deposition of Zn are temporally and spatially separated, achieving fast Zn redox kinetics and dendrite-free Zn (002) deposition. The flexible anode (Zn@LM-AgT) demonstrates stabilized Zn plating/stripping cycling over 700 hours with reduced overpotential, and when coupled with a vanadium-based cathode, the full cell exhibits six times higher remaining capacity after 1000 cycles compared to the reference cell. The delayed nucleation mechanism provides a novel approach to high-performance metallic anodes.

Additionally, prograde and perpendicular precession lead to a smooth transition between low and high flow states, while retrograde precession does not exhibit this behavior.

Summary: The properties of rotating turbulence driven by precession are studied using direct numerical simulations and analysis of the underlying dynamical processes in Fourier space. The study reveals that precession causes a linear instability in the background flow, leading to the formation of coexisting two-dimensional vortices and three-dimensional waves. The interaction between the vortices and waves is characterized by nonlinear energy transfer, while the precession mechanism counteracts the effects of rotation on the vortices.

Summary: The effect of the nutation angle on the flow inside a precessing cylinder is experimentally studied and compared with numerical simulations. The breakdown of the directly forced m =1 Kelvin mode and the transition between laminar and turbulent flows are investigated. The findings show that prograde rotation leads to an earlier breakdown, while retrograde rotation allows the forced mode to exist at higher Poincare numbers. The occurrence and intensity of an axisymmetric double-roll mode greatly influence the self-excitation condition of the kinematic dynamo study, which is sensitive to the nutation angle and Poincare number.

Summary: This paper investigates the resonance of atmospheric waves in planet-hosting solar-like stars to tidal forcing and their potential impact on space weather and dynamo activity. A forced wave model is formulated for the tachocline layer, which is considered as the birthplace of various magnetohydrodynamic planetary waves. The results show that Rossby waves resonating to low-frequency perturbations can reach significant velocity amplitudes, but this is strongly dependent on the unknown frictional damping parameter.

Summary: This study considers the magnetised spherical Couette (MSC) problem as a paradigmatic model in geo- and astrophysics to investigate bifurcations and chaotic flows in large-scale dissipative dynamical systems with symmetry. The goal is to understand the origin of chaotic transients and intermittent behavior through Hopf bifurcations involving invariant tori. Numerical evidence is provided to demonstrate the existence of a crisis event that destroys chaotic attractors and gives rise to chaotic transients. The study also reveals the involvement of unstable invariant tori in the time evolution of these chaotic transients. For one bifurcation sequence, the study shows that chaotic transients exhibit on-off intermittent behavior, and a possible explanatory mechanism is discussed.

Summary: The question of whether the solar dynamo is synchronized by tidal forces has recently gained renewed interest. In this study, we analyze cosmogenic radionuclide data to contribute to solving this longstanding puzzle. Our findings suggest that the C-14-inferred sunspot data are well compatible with a synchronized solar dynamo, with a relatively phase-stable period of 11.07 years, indicating the synchronizing role of the Venus-Earth-Jupiter system's spring tides.

Summary: Contactless Inductive Flow Tomography (CIFT) is a flow measurement technique for reconstructing global 3D flow in electrically conducting fluids. Understanding flow conditions in liquid metals is crucial for industrial processes like continuous casting of steel. CIFT can also be used in fundamental research to measure convective liquid metal flows. The technique relies on precise measurement of small magnetic field changes and solving the linear inverse problem to reconstruct the flow field. This publication showcases both fundamental and applied fluid mechanics use cases.

Summary: We studied a conventional a-O-dynamo model with meridional circulation that showed typical features of the solar dynamo, including a 20-year Hale-cycle period and a reasonable butterfly diagram shape. To explore the possibility of tidal synchronization of the solar cycle, we added a localized, time-periodic a-term in the tachocline region. Our results indicated that amplitudes of several decimeters per second are sufficient for this a-term to affect the underlying dynamo. We provided arguments suggesting that such amplitudes of a may be realistic, given the achievable velocities in the range of m/s, such as tidally excited magneto-Rossby waves.
