来源：ACS PublicationsImproving water retention in sandy soils remains critical for sustainable agriculture, with engineered nanoparticles emerging as potential amendments. This study presents a state-of-the-art pedostructure approach to investigate how negatively charged cerium oxide nanoparticles (CeO2–NPs) affect water holding capacity in silty loamy sand soil (83% sand, 13% silt, 4% clay) under saline and nonsaline conditions. Three objectives were addressed: (1) measuring the impact of different CeO2–NP concentrations on WHC and pore-scale water distribution, (2) assessing the effects of sal...

来源：ACS PublicationsNanocrystalline ceria exhibits nanozymatic activities, which are strongly affected by surface composition and surface Ce3+ concentration. Here, we use density functional theory to perform a scan of the compositional landscape of the most important {111}, {110}, and {100} ceria nanoparticle surfaces and their buffering activity toward reactive oxygen species (ROS) involved in the superoxide dismutase (SOD) and catalase (CAT) enzymatic mimetic activity of ceria. This study displays that pristine and surface sublayer oxygen-deficient surfaces can perform catalytic activities, w...

Unraveling the Photocatalytic Performance of La2O3 Nanoparticles for the Degradation of Six Organic Dyes 来源：ACS PublicationsLanthanum oxide (La2O3) nanoparticles stand out as promising photocatalysts due to their remarkable stability and photocatalytic properties. In this study, La2O3 nanoparticles were synthesized via a hydrothermal method and explored how varying calcination time (3 and 5 h) influences their structural, morphological, optical, and catalytic properties. X-ray diffraction (XRD) confirmed stable hexagonal structure, with crystallite sizes increasing from 32.79 to 45.49 nm,...

来源：ACS PublicationsThe rising interest in molten salts, both as thermal energy storage media and as high-temperature solvents for fissile materials in advanced nuclear reactors, has spurred significant growth in research on structural and functional salt-facing materials. Impurities, such as water, play a significant role in the degradation of materials in molten salt environments. Other impurities, such as fission products, are expected to accumulate in molten salts during normal reactor operation and can affect the properties of the salt and salt-facing materials. During normal reactor opera...
