ABSTRACT Non‐metallocene catalysts have shown great potential for modulating the polymer microstructure by changing ligand structure, but effects of structure and electronic property metal center on their catalytic performance remain underexplored. Herein, we designed synthesized two pairs isomeric tridentate β‐ketoimine complexes TiL a / b c d with methylthioaniline methylthioethylamine side arms, respectively, which exhibited moderate to extremely high activity over 10 6 g (mol Ti) −1 · h...
Based on Grassman's law of color mixing, the fine tuning Ca<sub>3−x</sub>Sr<sub>x</sub>(PO<sub>4</sub>)<sub>2</sub>:Eu<sup>2+</sup>,Mn<sup>2+</sup>is realized<italic>via</italic>solid-solution and energy transfer.
A series of Tb<sup>3+</sup>and/or Eu<sup>3+</sup>doped Na<sub>3</sub>La(PO<sub>4</sub>)<sub>2</sub>phosphors were successfully synthesized and their crystal structure photoluminescence (PL) properties investigated in detail.
Blue‐emitting phosphors A BaPO 4 :Eu ( =Na, K) are synthesized by the combustion‐assisted synthesis method. The formation of single phases has been confirmed X‐ray powder diffraction (XRD). photoelectron spectroscopy (XPS) is used to investigate europium valence in samples. Evidence found that samples prepared this paper exhibit a mixed‐valence state (Eu 3+ and Eu 2+ ). Photoluminescence (PL) results show NaBaPO KaBaPO emit strong blue light under UV excitation.
Abstract Eu 2+ /Mn ‐co‐doped white‐emitting Ca 5 (PO 4 ) 3 F phosphors have been synthesized by a combustion‐assisted synthesis method. The PXRD patterns confirmed the single‐phase fluorapatite crystal structure for all samples independently of their substitution level. Their luminescence properties reveal that developed can efficiently convert UV light in broad range from 250 to 420 nm into tunable white emission. Based on spectra and fluorescence decay curves, we confirm energy transfer Mn...

The calcination of ammonium metavanadate was investigated using simultaneous thermogravimetric analysis (TGA) and differential scanning calorimetry techniques. decomposition proceeded in three steps, kinetic performed under nonisothermal conditions an integral composite method. "model-free" method TGA data at various heating rates suggested that each step be subjected to a single process. master plot showed the reaction for steps best described by accommodated nucleation nuclei growth...
Abstract Thermal dehydration process of calcium oxalate monohydrate, CaC 2 O 4 · H O, was reinvestigated from a viewpoint reaction kinetics. On the basis data thermogravimetry, kinetic analysis performed under nonisothermal conditions using an integral composite procedure, which includes isoconversional method and master plots method. The results TGA at various heating rates suggested that followed single step with activation energy 99.02 ± 2.61 kJ/mol, method, described by R n model....
