Spectroscopic studies of noble metal incorporated lanthanide vanadates and YF3: Tb3+ nanoclusters encapsulated in hybrid hydrogels
Extensive analysis of europium doped yttrium vanadate (YVO4: Eu3+) and terbium doped yttrium fluoride (YF3:Tb3+) has been evaluated by means of powder X-ray diffractions, scanning electron microscope and luminescence spectroscopy techniques. The results demonstrate noticeable difference in emission spectra for the sample of YVO4: Eu3+ in the presence of Gd3+. As for the influence of the nanocrys...

53. [Materials Chemistry and Physics] Mechanically redox-tunable hydrogels reinforced by hydrophobic association and metal ion coordination
Generally understanding of stimuli-responsive hydrogels is sol-gel transition under various stimulus. However, current knowledge from stimuli-responsive hydrogels always meets poor mechanical property with a gel state. Although the proposed method of hydrophobic effect usually introduced into hydrogels to design various types of tough hydrogel, the mechanically tunable hydrogel by stimulus respo...

Continuous synthesis for zirconium metal-organic frameworks with high quality and productivity via microdroplet flow reaction
Zirconium metal-organic frameworks (Zr-MOFs) represent the most promising candidates among MOFs for industrial utilizations owing to their high porosity and excellent stability. However, the efficient synthesis of Zr-MOFs combining with continuous production, high productivity and good product quality still remains a critical issue for practical applications. Herein, we report an efficient metho...

High Oxygen Reduction Activity on a Metal-Organic Framework derived Carbon Combined with High Degree of Graphitization and Pyridinic-N Dopants
N-doped porous carbons have been considered as one of the most promising earth-abundant catalysts for the oxygen reduction reaction (ORR) owing to their high activity and excellent stability. Among various types of N-containing groups, pyridinic-N has been identified as the most effective catalytic sites for the ORR, as demonstrated by a recent study. However, the fabrication of porous carbons w...

Metal-organic Frameworks Derived CoS2-Co/N-doped Porous Carbon with Extremely High Electrocatalytic Stability for the Oxygen Reduction Reaction
The electrocatalytic performances for the oxygen reduction reaction (ORR) highly depend on the structure and composition of catalysts. In this work, a novel non-precious metal catalyst (CoS2-Co/N-doped porous carbon) has been fabricated by the carbonization of metal-organic frameworks (MOFs) with a consequent sulfuration process. The resultant nanocomposite exhibits highly desirable structure feat...

[J.Phys.Chem.C ]Highly Efficient Electromagnetic Wave Absorbing Metal-Free and Carbon-Rich Ceramics Derived from Hyperbranched Polycarbosilazanes
Abstract: The highly efficient electromagnetic (EM) wave absorbing metal-free and carbon-rich ceramics derived from hyperbranched polycarbosilazanes were presented in this contribution. The novel metal-free hyperbranched polycarbosilazanes with pendant cyano groups (hb-PCSZ-cyano) were synthesized through aminolysis reaction and subsequent Michael addition reaction, i.e. cyanoethylation reaction...

Highly 2,3-Selective Polymerization of Phenylallene and Its Derivatives with Rare-Earth Metal Catalysts: From Amorphous to Crystalline Products
Rare-earth metal complexes (Flu-CH2-Py)Ln-(CH2SiMe3)2(THF)n (Ln=Sc(1), Lu(2), Tm(3), Y(4) andGd(5)), upon the activation of [Ph3C][B(C6F5)4] and AliBu3,were employed to catalyze the polymerization of allene derivatives under mild conditions. The Gd, Y, Tm, Lu metal based precursors exhibited distinguished 2,3-selectivity(>99.9%) for phenylallene (PA) polymerization, whereas the smallest Sc me...
