Summary: The problems of zinc anode, such as dendrite growth and hydrogen evolution, significantly impair the performance of zinc batteries. The solid electrolyte interphase (SEI), crucial for achieving high reversibility of lithium anode in non-aqueous organic solvents, also contributes to the improvement of zinc anode performance in aqueous electrolytes. However, current research on the interphase for zinc electrodes is fragmented, lacking a deep understanding of the underlying causes or general design rules for SEI construction. The high reactivity of water molecules poses a serious challenge for effective SEI formation.

The tuned layered polyaniline achieved high volumetric capacity of 196 mAh cm-3 at 0.01 V vs. Li/Li+ and allowed the fabrication of a high voltage PI-LISC with a high energy density of 100.5 Wh L-1, a high power density of 13.7 kW L-1, and excellent capacity retention of 90.1% after 10,000 cycles. Our findings present a significant step forward in opening up new opportunities for high energy and high power PI-LISCs.

Summary: The problem of robust state estimation for a class of uncertain nonlinear systems with Markov jump is investigated. The Takagi-Sugeno (T-S) fuzzy model is used to represent the difficult-to-describe uncertain nonlinear system. A robust state estimator for linear subsystems is developed through a robust state estimation method based on sensitivity penalty, and the fuzzy robust state estimator is obtained by fuzzy rules. The stability and boundedness of the fuzzy robust state estimator are proved under assumption conditions to ensure reliability.

Summary: In this paper, the state estimation problem of discrete-time T-S fuzzy systems with random parametric uncertainties and deterministic external inputs is investigated. A new approach is proposed to rearrange the structure of the T-S fuzzy model and approximate the nonlinear system more accurately using a set of linear uncertain models. A robust state estimation method based on sensitivity penalty is used to estimate the state of the linear uncertain systems, and the estimated subsystem is weighted and fused by the membership function to obtain the state of the discrete-time T-S fuzzy systems. The steady-state analysis and properties of the fuzzy state estimator are discussed, and simulation results are presented to demonstrate the effectiveness of the proposed approach.

Summary: In this paper, the event-triggered robust state estimation problems for nonlinear networked systems with constant measurement delays against denial-of-service (DoS) attacks are addressed. The extended Kalman filter (EKF) computation generates errors of linearization approximations, which can lead to increased state estimation errors and subsequently amplifies the linearization errors. DoS attacks overload the communication networks, interfering with the transmission of measurements to the remote robust state estimator, while the communication rate is constrained. To defend against DoS attacks and linearization errors, an event-triggered robust state estimation algorithm based on sensitivity penalization with an explicit packet arrival parameter is proposed. Additionally, a novel state augmentation method is devised to overcome the presence of measurement delays. Numerical simulations demonstrate that the proposed robust state estimator significantly improves the accuracy of state estimation.

Summary: This paper investigates the robust fusion estimation problem for multi-sensor systems with communication constraints, parameter uncertainty, d-step state delays, and deterministic control inputs. The state augmentation method is utilized to transform a time-delay system into a non-time-delay one. An event-triggered transmission strategy has been adopted to effectively alleviate the communication burden from the sensor node to the fusion center. The fusion estimator handles packet drops arising from unreliable channels, and the corresponding pseudo-cross-covariance matrix is provided. Some conditions are given to ensure that the estimation error of the robust fusion estimator is uniformly bounded. Two sets of numerical simulations are provided to illustrate the effectiveness of the derived fusion estimator.

Summary: In this paper, the finite-time boundedness problems for large-scale continuous-time networked dynamical systems with arbitrary interactions and different dynamics of subsystems are investigated. Sufficient conditions for the design of finite-time boundedness state feedback controller are derived, utilizing the block-diagonal structure of system parameter matrices and the sparseness of system topology. Conditions depending only on parameter matrices of individual subsystems are also provided. The distributed output feedback controller with finite-time boundedness is also designed and its conditions are derived. Numerical simulations are conducted to validate the effectiveness of the derived conditions for a large-scale networked system.

Summary: This study resolves the issue of carrier recombination on the dual surfaces of the m-BiVO4 component in water oxidation by constructing an m-BiVO4/carbon nitride (C3N4) Z-scheme heterostructure based on the m-BiVO4/reduced graphene oxide (rGO) Mott-Schottky heterostructure. The rGO effectively accumulates photogenerated electrons from m-BiVO4 and facilitates their diffusion through a highly conductive carbon network. The Z-scheme electron transfer at the heterointerface of m-BiVO4/C3N4 leads to spatial separation of electron-hole pairs and maintains strong redox potentials, resulting in significantly improved O-2 yield and the generation of center dot OH and center dot O-2(-) radicals.

Summary: Polymeric conducting binders have significant research value as they can serve as both binders and conducting agents, increasing the proportion of active materials in batteries and the volumetric energy density. This study explores the potential of a composite of PEDOT:PSS and polyethylene glycol (PEG) as a high-performing binder for silicon anodes. The addition of PEG polymer enhances the conductivity of PEDOT:PSS and improves the mechanical properties of the silicon anode, resulting in extended cycle endurance. The use of operando optical microscopy allows for direct observation of the binder's operation. Consequently, the bifunctional PEDOT:PSS/PEG binder shows promise for high-performance lithium-ion battery binders.

In this study, a hydroxyl-rich copper fluoride (Cu2(OH)3F) was proposed as a conversion cathode, coupled with an electrolyte additive engineering, to address the poor reversibility issue.
