Summary: This study evaluated 12 technical routes (Electricity, Gasoline, Hydrogen, Ammonia) from technical, environmental and economic perspectives and compared their comprehensive competitiveness. The results show that renewable energy-based technical routes reduce carbon emissions and energy consumption, but they have relatively high economic costs. Battery electric vehicles have the best comprehensive competitiveness at room temperature, while ammonia-hydrogen fuel cell electric vehicles can be applied in special scenarios.

Summary: In this research study, a real model of a hydrogen fuel cell vehicle is simulated using Simcenter Amesim software. The impact of fuel cell degradation on the performance of hydrogen vehicles is examined, and it is found that a degraded fuel cell increases fuel consumption by 14.3%. A comprehensive life cycle assessment is performed, comparing the emissions of the hydrogen vehicle with a gasoline vehicle. Different methods of hydrogen production and power sources for electrolysis are considered. The study also reveals that a hydrogen vehicle with a degraded fuel cell emits lower CO2 than a gasoline vehicle, but using hydrogen from electrolysis results in higher CO2 emissions compared to a new hydrogen vehicle.

Summary: Sustainable energy development is a globally important research area that requires effective design processes and sustainable energy sources. A study conducted experiments using a solar heating system with two-parabolic trough collectors (PTC) to operate a Rankine cycle-based fuel cell for hydrogen production. The results showed that by optimizing the heat transfer rate and using a flow rate of 0.38 kg/s for the heat transfer fluid (HTF), the system achieved a thermal efficiency of 82% and a heat gain of 27589 kW. Increasing the flow velocity of the HTF improved both the solar collector's efficiency and the electrical energy output for the fuel cell, resulting in higher hydrogen production rates. The study also conducted a preliminary cost analysis using the solar advisor model (SAM) to determine the electric cost of the integrated system.

The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
