Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated. The high-loading and dense sulfur cathode fabricated by this method delivers a high specific capacity at a very low electrolyte/sulfur ratio.

Summary: In this study, the effect of defects on phase transition in high-entropy alloys was investigated by comparing the structure evolutions of ball-milled and as-cast samples. The ball-milled alloy exhibited a lower phase-transition-pressure and a higher fraction of hcp phase due to a higher density of defects and a lower nucleation energy barrier compared to the as-cast alloy. The findings suggest a potential approach for customizing the percentage of different phases in high-entropy alloys to improve their structure and characteristics as a novel engineering material.

Summary: The rapid solidification of intermetallic Ni3Sn compound from an undercooled liquid was studied, revealing the growth of ordered and disordered cubic solids at low and high undercooling, respectively. The disordered cubic solid was reordered after rapid solidification and underwent a solid-state transformation during cooling. High density crystal defects and nanodomains were observed in the transformed matrix, which were determined to be antiphase domains with chemical disorder through a HAADFSTEM study. These findings suggest the potential for online control of mechanical properties in additively manufactured intermetallics.

Summary: Through large-scale molecular dynamics simulations, we studied the phase behavior of high-pressure ice. The results indicate that some ice phases with a body-centered cubic oxygen lattice belong to the same thermodynamic phase under different conditions, while superionic ice has a first-order phase boundary. Furthermore, at higher pressures, the activation barrier for ice transformation gradually increases. Our study reveals peculiar solid-solid transition mechanisms in high-pressure ice phases.

Summary: In this study, the limited microstructural evolution of electrodeposited nanocrystalline Ni during isothermal annealing is investigated using in situ X-ray diffraction technique. The results show that the lattice contraction of Ni may be attributed to the reduction in grain boundary excess volume and the gradual improvement of lattice perfections is observed during nanostructural relaxation. Additionally, the microhardness evaluation indicates a significant hardening of nanocrystalline Ni subjected to low-temperature annealing.

Summary: Ptychography is a high-resolution diffraction imaging technique that is sensitive to experimental variations. High-speed data acquisition with short exposure can minimize the impact of experimental variations, and continuous multi-pass scan via high-speed ptychography can achieve high-resolution imaging. This low-dose scan strategy is important for radiation-sensitive sample studies and time-resolved imaging.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: Water is essential for the survival of living organisms, but industrialization has led to contamination of water sources with heavy metals and harmful pollutants. Magnetic nano ferrites have shown potential in effectively removing heavy metals from water due to their magnetic characteristics, high surface area, surface active sites, chemical stability, and ease of modification. This review explores recent literature on the synthesis and application of magnetic ferrites for removing heavy metals from water, aiming to provide a comprehensive understanding for future research.

Summary: A variety of hierarchical nanoporous silica aerogels were synthesized from well-dispersed silica sols, exhibiting diversified particle distributions and excellent thermal properties. The silica aerogels showed low thermal conductivity and high-temperature resilience. Surface modification and dilution of silica sols further improved the thermal resistance of the aerogels. The resilient skeleton structure developed from tiny particles effectively restricted heat dissipation and maintained the porous network at high temperatures.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
