Observed values of the magnetic moments of the antimony isotopes and related nuclei are shown to be compatible with a description of the nuclei as involving orbital angular momentum carried by a triton. It is found that both ${L}_{t}{S}_{p}$ and ${L}_{n}{J}_{p}$ coupling types are needed for different nuclei.

Aqueous antimony (Sb) pollution from human activity is of great concern in drinking water due to its adverse health effect. Magnetic Fe 3 O 4 particles, with high separation ability from solution, have been considered as a low-cost Sb adsorbent for contaminants. However, the limited adsorption capacity has restricted its practical …

The process of Sb(III) removal by MNP@hematite particles as a function of time was studied and the results were depicted in Fig. 2.The concentration of Sb could be reduced from 110 μg/L to below 5 μg/L by MNP@hematite within 10 min, and the adsorption equilibrium could be obtained in 2 h.The final Sb concentration was on the …

Antimony contaminant not only comes from the natural process of antimony dust, but also from industrial wastewater emission in metallurgy, and dyeing industries, etc (Yao et al., 2021).No matter what antimony species enters the water, it will threaten the health of animals and plants (Fig. 1).Due to various human activities, …

Single-layer antimony or antimonene is a recently discovered two-dimensional material with high environmental stability and appealing electronic properties. Antimonene is characterized by strong spin-orbit coupling, which suggests unconventional behavior in magnetic fields. In this paper, we report on a computational study of the …
