Microwave-accelerated rapid synthesis of high- quality yttrium iron garnet nano powders with improved magnetic properties
High-quality cubic yttrium iron garnet (YIG) nano powders have been rapidly synthesized by a chemical co-precipitation plus microwave heating method. The average particle size of the synthesized YIG nano powders were about 30 nm. The atoms in the particle were near completely orderly arrangedby microwave activation, resulting in a higher saturation magnetization of 29.7 emu/g and a lowercoercive...

Development of visible light response of CeO2-x with the high content of Ce3+ and its photocatalytic property
Photocatalysts that are responsive to visible light are necessary to
utilize solar. We prepared a reduced CeO2-x with absorption in the
visible region by a simple solvothermal method. A new absorption peak
appeared around 500 nm (SPR), which is the origin of Ce3+. To elucidate
the relationship between the Ce3+ and activity, decomposition of
isopropyl alcohol (IPA) to generat...

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...

Novel high TEMPO loading magneto-polymeric nanohybrids: An efficient and recyclable Pickering interfacial catalyst
We report herein the design and preparation of novel magneto-polymeric nanohybrids that can be used as efficient and recyclable Pickering interfacial catalyst (PIC) in selective oxidation of alcohols. The nanohybrids Fe3O4@SiO2@PTMA, bearing catalytic TEMPO functionalities, were synthesized through distillation-precipitation polymerization (DPP) of the precursor monomer 2,2,6,6-te...

High efficiency organic solar cells based on amorphous electron-donating polymer and modified fullerene acceptor
The current manuscript examines the structure and property relationship of amorphous conjugated polymer based bulk heterojunction solar cells. Solvent vapor annealing (SVA) is used to optimize the morphology. It is seen that the structure order of the blended thin film does not change but phase separation becomes prominent. The space charge limited current and admittance spectroscopy reveals that ...

Ultrafine TiO2 Nanoparticles Confined in N-Doped Porous Carbon Networks as Anodes of High-Performance Sodium-Ion Batteries
TiO2-based nanocomposites with rationally designed size, structure, and composition are highly desirable for Na-ion storage. In this work, various TiO2/N-doped porous carbon nanocomposites (TiO2/NC) have been fabricated by directly carbonizing NH2-MIL-125(Ti) at different temperatures. These TiO2/NC nanocomposites exhibit unique structure features, such as ultrafine TiO2 nanoparticles, micro-mesop...

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...

(Soft Matter) A Homeotropic Main-Chain Tolane-Type Liquid Crystal Elastomer Film Exhibiting High Anisotropic Thermal Conductivity
The development of pure polymeric films with anisotropic thermal conductivities for electronic device packaging applications has attracted intense scientific attention. In order to enhance the polymeric film’s normal-direction thermal conductivity, homeotropic alignment of macromolecular chains is the primary concern. One of the promising preparation strategies is to perform in situ photopolyme...
