来源:ACS PulicationsGadolinium-based metal–organic frameworks (MOFs) are attractive due to their potential magnetic applications such as magnetic refrigeration, magnetic resonance imaging, and quantum information science. In this work, Gd3+-based MOFs containing binuclear metal nodes and fluorinated hexaclusters have been prepared exhibiting paramagnetic behavior, and their crystal structures were obtained. A two-dimensional MOF (Gd-BCA-2D) having the sql topology was prepared by the hydrothermal reaction of Gd3+ and bicinchoninic acid (BCA). A fluoro-bridged hexacluster-based MOF (Gd-BCA-3D) ha...

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,...
