Effects of rare-earth substitution on the stability and electronic structure of REZnOSb (RE=La–Nd, Sm–Gd) investigated via first-principles calculations

Highly Efficient Composite Flame Retardants for Improving the Flame Retardancy, Thermal Stability, Smoke Suppression, and Mechanical Properties of EVA

“…The samples were called S-LaMgAl, S-CeMgAl, and S-NdMgAl, respectively. Rare-earth elements are an important material that can be used in many fields such as global communications, medicine, agriculture, batteries, and hybrid engines due to their electronic, magnetic, and catalytic properties [14][15][16][17][18]. However, the influence of a composite flame retardant including REEs, LDHs, and IFRs on the flame retardancy of EVA has not been reported.…”

Conversion of CO2 into Cyclic Carbonates under Ambient Conditions Catalyzed by Rare-Earth Metal Complexes Bearing Poly(phenolato) Ligand

“…Rare-earth metals (RE) find wide applications in various fields due to their distinctive physical and chemical properties. RE-containing compounds have been used as optical, electrical, and magnetic materials. , They have also been developed as catalysts, possessing advantages of good activity and selectivity . Rare-earth metals are highly oxyphilic and Lewis acidic, which makes their complexes potentially useful for the cycloaddition of CO 2 and epoxides. , To date, cyclic carbonate synthesis catalyzed by a RE-based complex still requires high temperature and pressure, which include SmOCl (supercritical CO 2 , 200 °C), Sc­(OTf) 2 (20 bar CO 2 , 120 °C), and polynuclear lanthanide complexes (10–20 bar CO 2 , 120 °C), ,, Our group has been devoted to exploiting the application of RE complexes in CO 2 transformations. ,,,,− We reported a RE complex bearing ethylenediamine-bridged poly­(phenolato) ligands, which is the first RE complex that catalyzed the cycloaddition reaction under mild conditions (85 °C and 1 bar CO 2 for monosubstituted epoxide or 10 bar CO 2 for disubstituted epoxide) .…”

“…RE-containing compounds have been used as optical, 67 electrical, and magnetic materials. 68,69 They have also been developed as catalysts, 70 possessing advantages of good activity and selectivity. 71 Rare-earth metals are highly oxyphilic and Lewis acidic, which makes their complexes potentially useful for the cycloaddition of CO 2 and epoxides.…”

Improvement of the thermal and thermo-oxidative stability of high-density polyethylene by free radical trapping of rare earth compound

“…Rare earth elements have been the object of considerable scientific and technological interest due to their distinctive optical [2][3][4], electronic [5,6], magnetic [7,8], anticorrosive [9,10] and catalytic properties [11]. Because of brilliant thermal and flame retardant properties, rare earth compounds have been considered as thermal stabilizer, flame retardant, or synergistic agent used with other thermal stabilizers and flame retardants [12][13][14][15].…”
