Summary: Lithium-sulfur (Li-S) batteries offer high-density and low-cost energy storage, but the transport of polysulfides hinders their practical utilization. To overcome this limitation, a novel strategy using oxidative chemical vapor deposition (oCVD) is proposed to limit the shuttling of polysulfides in the cathode. The gas-phase approach involves a conducting and conformal polymer coating that eliminates traditional binders, enhances sulfur conversion kinetics, and inhibits polysulfide shuttling. Experimental and theoretical investigations demonstrate the physical and chemical confinement of polysulfides in the cathode, resulting in high capacity retention and specific energy, proving the potential for practical applications.

Summary: A thin (MXene/PP/Cu-TCPP) Janus separator was designed to address the rapid capacity fading and poor safety of lithium-sulfur batteries. The separator had an anisotropic spatial heterogeneity, with a sulfophile cathode-facing surface and a multifunctional ionic sieve on the opposite side. The MXene layer acted as an expanded S host, confining sulfur and its intermediates, while the MOF layer served as an ionic sieve and prevented dendritic growth of Li.

Summary: Three novel all-visible-light triggered fluorescent molecular photoswitches have been designed and prepared, achieving reversible photochromic and fluorescent switching in dilute solutions, films, and powder states. Solvent polarity can alter the photochromic abilities of two distinct conformations, and the size difference between the two conformations is one of the largest changes among photochromic molecules based on dithienylethene. The accompanying conformational changes provide insights into the relationship between solvent characteristics, crystal structure, and intermolecular interaction in solid state for all-visible-light triggered photoswitching molecules.

Summary: (1-x)(0.99Na0.5Bi0.5TiO3-0.01BiYbO3)-xSrTiO3 relaxor ferroelectric ceramics were fabricated and their crystal structure, surface morphology, dielectric, ferroelectric, and energy storage properties were investigated. The introduction of STO effectively refined the grain of NBT-based ceramics and enhanced its relaxation behavior. Adding STO also increased the electric breakdown field and reduced remnant polarization, significantly improving the energy storage performance. A moderate energy storage property with large Wrec (approximately 2.5 J/cm(3)) and high η (approximately 80.97%) was achieved at 260 kV/cm for x = 0.4. This work provides an effective strategy for enhancing the energy storage performance of NBT-based relaxor ferroelectric ceramics applied in pulsed power devices.

Summary: Closed coal bunkers have become a new storage method for coal-fired power stations. However, the heat generated by the constant oxidation of coal and the confined environment of the bunker make it difficult for the heat to dissipate, leading to frequent fires. Therefore, studying the combustion characteristics of coal piles is crucial for the safety design of coal bunkers.

Summary: This study examines the effects of fire location and air volume on fire development in single-ended tunnel fires with forced ventilation. The results show that the airflow can be divided into three regions, and the distance between the fire source and the excavation face influences the maximum ceiling temperature rise. It is also found that CO can easily accumulate on certain sides of the ventilation duct. Increasing the air volume decreases the CO concentration and maximum ceiling temperature rise, but also increases the risk for downstream regions. These findings are valuable for firefighting and personnel evacuation in single-ended tunnels.

Summary: This paper investigates the frequency regulation and active power sharing problem in islanded AC microgrids. A novel robust distributed secondary control scheme is proposed to restore frequency to the nominal value and achieve precise active power sharing in finite-time. The proposed control method reduces communication resources and controller updates by using an event-triggered strategy. The stability of the control method is analyzed and there is no Zeno behavior. Numerical simulations are presented to validate the effectiveness of the proposed controller.
