Au/Ag@polyoxometalate core-shell structures: from nanoparticles to atomically precise nanoclusters.

This review summarizes the progress in the research on polyoxometalate (POM)-decorated gold (Au) and silver (Ag) core-shell structures (Au/Ag@POMs), emphasizing their substantial application potential in catalysis, medicine, and biology. It outlines the central strategies for fabricating Au/Ag@POMs with diverse morphologies and dimensions, leveraging POMs as protective ligands and reducing agents as well as for ligand exchange. Of particular note is the focus on the analysis of the nanoparticle size, shape, and intricate architecture of POM shells using cryo-electron microscopy techniques.

Enantioselective Synthesis of Homochiral Hierarchical NdFe-Oxo Cluster from Racemic NdFe-Oxo Cluster.

Enantioselective synthesis of homochiral rare earth clusters is still a great challenge. In this work, we developed an efficient "cluster to cluster" approach, that is, a pair of enantiomerical /-{NdFe}-oxo clusters were successfully obtained from the presynthesized racemic {NdFe}-oxo cluster. /-hydrobenzoin ligands trigger the transformation of the pristine clusters by an SN-like mechanism.

Doping transition metals to modulate the chirality and photocatalytic activity of rare earth clusters.

In this paper, we report the successful assembly of achiral {LnM} ([LnM(μ-OH)(acac)(CHO)(CHOH)], Ln = La, M = Mn, Co, Fe) and chiral {NdFe} ([NdFe(μ-O)(μ-OH)(acac)(NO)(CHOH)(HO)]) rare earth clusters using achiral rigid ligands and a transition metal doping strategy. {LnM} can be viewed as the fusion of two {LnM} tetrahedrons by sharing vertices. {NdFe} results from the fusion of four {LnM} tetrahedrons by vertice and edge sharing.

Effects of Sacubitril/Valsartan on resistant hypertension and myocardial work in hemodialysis patients.

Growing evidences have confirmed the effect of Sacubitril/Valsartan (SV) on antihypertension and cardiac protection in general population. However, there was no prospective study about the effect and safety of SV on resistant hypertension and myocardial work in hemodialysis patients. In this single-center, prospective, before-after study, enrolled patients were endured with resistant hypertension for more than 6 months.
