Summary: In this study, NaY-zeolites were modified by combining Cu ion-exchange and Na2O or CuO impregnation for adsorptive desulfurization. The results showed that Na2O promoted the adsorption of TBM, while CuO inhibited it. Among the tested samples, the Cu ion-exchanged Y-zeolite containing Na2O showed the most efficient adsorption performance with a 3.97 wt% uptake for TBM, which is 30% higher than that of the Cu ion-exchanged Y-zeolite. The Cu ion-exchanged Y-zeolite containing CuO showed the lowest adsorption ability with a 2.21 wt% uptake for TBM.

Summary: The study shows that NaY modified with ammonium nitrate and citric acid increases the adsorption capacity of thiophene in simulated coke oven gas. On medium-strong Bronsted acid sites, thiophene polymerization reaction occurs easily, leading to a significant decrease in Q(b-thiophene) due to acid sites covering and micropores blocking. The increase of Lewis acid is beneficial to desulfurization and provides a wider temperature region for thiophene removal compared to Bronsted acid.

Summary: The hydrogen production from natural gas reforming is hindered by the presence of sulfur compounds, which cause catalyst deactivation. Therefore, the removal of sulfur compounds is necessary before the application of natural gas in hydrogen production. Cu-ion-exchanged zeolites show effective adsorption performance for the removal of sulfur compounds, and Cu(Ac)2-exchanged NaY zeolite exhibits the highest adsorption uptake for tetrahydrothiophene (THT). The distribution of Cu2+ within the zeolite framework varies depending on the anions present in the Cu precursors and influences the adsorption uptake for THT.

Summary: A major challenge in manufacturing large-aperture aspheric optical components of glass ceramics is the long processing time. Ultrasonic vibration-assisted grinding (UVG) can greatly reduce the subsequent polishing process, but the surface creation mechanism of UVG-treated glass ceramics is not well-studied. This study investigates the surface formation mechanism of UVG-processed ceramics using two UVG methods: rotary ultrasonic vibration-assisted vertical grinding (RUVG) and parallel grinding (RUPG). The results show that RUVG is more suitable for high precision and efficiency grinding of aspheric surfaces compared to RUPG.

Summary: In this work, the effects of zero-dimensional bulges on the geometric, electronic, and transport properties of graphene were systematically studied through theoretical calculations. It was found that bulge formation introduces mechanical strains and leads to charge redistribution in the structure. Additionally, visible energy band splitting and increased electron states were observed with the occurrence of bulges. However, the formed bulges decreased carrier mobility and increased phonon scattering, thus diminishing electron and heat transport in graphene.

Summary: The study focused on the seasonal cycling of mercury and methylmercury in vegetated sediments in the Dongtan wetlands of the Yangtze River Estuary, as well as the potential health risk of mercury in estuarine wetlands. The results revealed significant differences in the seasonal variations of total mercury and methylmercury, with the activity of methylating bacteria identified as a major contributor to elevated methylmercury levels. It was also found that the addition of mercury greatly increased the production of methylmercury, even under suboxic conditions, indicating a long-term health risk in the wetlands.

Summary: There is increasing evidence that biochars (BCs) have the potential to remediate mercury-contaminated paddy soils and reduce the accumulation of methylmercury (MeHg) in rice grains. The addition of BCs from different sources significantly decreased the extractable MeHg in the soil, and low doses of BCs greatly reduced MeHg levels in rice grains. These findings suggest that BCs produced from various raw carbon materials have the potential to effectively mitigate MeHg accumulation in rice and can be used in remediating moderately contaminated paddy soils.

Summary: This paper systematically reviews the research on salinity optic fiber sensors (OFSs) for seawater based on the refractive index (RI) measurement principle. It discusses the measurement demand of seawater salinity in marine environmental monitoring, the definition of seawater salinity and the correspondence between seawater RI and salinity. The study also summarizes the sensing mechanisms, research progress and measurement performance indices of existing fiber optic salinity sensors, and recommends the use of absolute salinity for calibration and measurement based on the Thermodynamic Equation of Seawater-2010 (TEOS-10). The research progress shows that fiber-optic RI sensors are ideal for real-time, in situ measurement of seawater absolute salinity and have great potential for application in deep ocean measurements.

Summary: Supercapacitors cannot replace lithium-ion batteries due to their lower energy density and voltage range. However, they can serve as supplements for battery charge storage or transmission devices. This study focuses on the design of transition metal oxide-based electrodes with high cycling capacitance retention. The researchers found that Mn doping enhances the adsorption and desorption of certain ions, leading to improved electrochemical reactions. The use of SAC@Ni2Co0.95Mn0.05-LDH electrode material in the asymmetric supercapacitor (ASC) showed high energy density and excellent capacitance retention, making it suitable for wind energy storage and conversion.

Summary: This study prepared a series of MOF-based derivatives using suitable methods and evaluated their electrochemical performance. It was found that phosphating treatment can enhance the material's electrical conductivity, while the layered structure facilitates the intercalation/deintercalation of electrolyte ions, and oxidation inhibits the release of electrochemical performance. Therefore, the enhancement effect in terms of electrochemical performance is ranked as follows: phosphorization > layer structure > oxidation. This study provides reliable criteria for the design and screening of advanced electrode materials.

Summary: This study explores the safe spaces maintained by pedestrians and e-bicyclists when crossing streets. Using drone footage, the researchers found that e-bicyclists maintain semi-elliptical safe spaces while pedestrians maintain semi-circular safe spaces, with the sizes of these spaces increasing in proportion to relative speeds. The findings bridge an empirical gap in the existing literature and have practical implications for urban planning, traffic management, and the safety of vulnerable road users.
