TEMPO in Chemical Transformations: From Homogeneous to Heterogeneous
The organic nitroxyl radical, TEMPO (2,2,6,6-tetramethylpiperidine-N-oxyl), finds a variety of industrial applications for chemical transformations. Due to the economic and environmental concerns, the recovery and reuse of TEMPO with maintained high activity are utmost important. In this critical review, we summarize the most important advances made by the scientific community in TEMPO immobiliz...

Interfacial Chemical Oxidative Synthesis of Multifunctional Polyfluoranthene
A novel polyfluoranthene (PFA) exhibiting strong visual fluorescence emission, a highly amplified quenching effect, and widely controllable electrical conductivity is synthesized by the direct cationic oxidative polymerization of fluoranthene in a dynamic interface between n-hexane and nitromethane containing fluoranthene and FeCl3, respectively. A full characterization of the molecular structure ...

Fabrication of Oxidized Sodium Carboxymethylcellulose from Viscose Fibers and Their Viscosity Behaviors
关键字：Oxidized Sodium Carboxymethylcellulose, Viscose Fibers
The oxidized sodium carboxymethylcellulose (O-CMC) fibers have been successfully synthesized via the oxidation-etherification method. Subsequently, the O-CMC fibers are characterized by Fourier transform infrared (FT-IR), 13C nuclear magnetic resonance (13C-NMR) and X-ray diffraction (XRD). In addition, the viscosity behaviors of the O-CMC aqueous solution have been investigated at five temperatur...

Bioinspired Micro-/Nanostructure Fibers with Water collecting Property
关键字：Bioinspired fibers, Micro- and nanostructure, Water Collection
We review the recent researches on structure-induced water collecting property of spider silk and bioinspired fibers. Since the capture silks of cribellate spiders have a unique wet-rebuilt structure with spindle-knots and joints for directional water collection, we are inspired to fabricate a series of artificial gradient micro-/nanostructure fibers. These fibers display excellent functions such ...
