Article Abstract
A power reactor in China was used as the subject, and based on the composition of its spent fuel, simulated waste basaltic glasses were prepared by the solid-state melting method. Among them, Ce/Ce, Nd and La are used to simulate Np/Np, Am and U in high-level nuclear waste (HLW), respectively. The structure, thermal stability and leaching characteristics of basaltic glasses with different contents of simulated waste were investigated. The XRD/SEM-EDX/Raman results revealed that the loading of simulated waste in basaltic glass reached ~ 25 wt%, and NiFeO crystals precipitated when the simulated waste content reached 25 wt%. When the content of simulated waste reached 40 wt%, a small amount of yellow material precipitated from the upper surface of the sample. The DSC and ASTM standard MCC-1 results indicated that all the samples had good thermal stability and leaching resistance.

High Capacity and Efficient Adsorption of Lutetium(III) by the Metal-Organic Framework HKUST-1 in Simulated Medical Wastewater.

Lutetium (Lu(III)), a heavy rare earth element, plays a critical role in advanced industrial processes and nuclear medicine applications. Given its high economic value and potential environmental risks, the recovery of Lu(III) from medical wastewater is both necessary and urgent. However, previous studies on the adsorption behavior of Lu(III) have been limited by low adsorption capacity, competition from coexisting metal ions, and the influence of environmental temperature.

Agricultural sources, landfills, and hazardous waste disposal sites (HWDS) are major hotspots for the spread of groundwater antibiotic resistance genes (ARGs) and human bacterial pathogens (HBPs). However, there is a lack of systematic understanding regarding the environmental behavior of groundwater ARGs, the pathogenic risks of HBPs, and the relative contribution mechanisms of different sources, presenting critical scientific challenges for developing targeted groundwater pollution control strategies. To address this, this study collected 26 groundwater metagenomic samples to characterize the composition, influencing factors, and health risks of ARGs and HBPs near key ARG reservoirs, and constructed a source-tracking indicator system.

Background: Immune checkpoint inhibitors (ICIs) are clinically beneficial but associated with high costs that represent a growing challenge for healthcare budgets and may affect affordability, especially in resource-limited settings. Moreover, the healthcare sector is a significant source of greenhouse gas emissions, and medication-related waste-such as that from vial-based therapies-has been identified as a contributing factor. Alternative dosing strategies could reduce the environmental and financial impact of ICI therapy while maintaining clinical safety and efficacy.

Geopolymers are aluminosilicate materials that exhibit effective immobilization properties for low-level radioactive nuclear waste, and more specifically for the immobilization of radioactive cesium. The identification of the cesium-binding sites and their distribution between the different phases making up the geopolymeric matrix can be obtained using solid-state NMR measurements of the quadrupolar spin Cs, which is a surrogate for the radioactive cesium species present in nuclear waste streams. For quadrupolar nuclei, acquiring two-dimensional multiple-quantum experiments allows the acquisition of more dispersed spectra when multiple sites overlap.

Zeolite synthesis from fly ash offers recycling and environmental benefits for carbon dioxide capture, but varying fly ash composition from different sources has different compositions, leading to inconsistent adsorption results. To achieve high CO adsorption performance and stability in zeolite synthesis from fly ash systems, this study established an element-controlled simulated fly ash system with Ca/Fe gradient differences. Hydrothermal synthesis yielded zeolites with optimized oxide ratios for CO adsorption.
