Probing Molecular Structures of Polymer/Metal Interfaces by Sum Frequency Generation Vibrational Spectroscopy
Sum frequency generation (SFG) vibrational spectroscopy has been applied to investigate the molecular structure of the buried poly(methyl methacrylate) (PMMA)/silver (Ag) interface. To elucidate such a structure, PMMA films with different thicknesses deposited on Ag substrates have been studied in the experiments. SFG signals collected from such PMMA films are interference res...

Effect of large pore size of multifunctional mesoporous microsphere on removal of heavy metal ions
Pore size of mesoporous materials is crucial for their surface grafting. This article develops a novel multifunctional microsphere with a large pore size mesoporous silica shell (ca. 10.3 nm) and a magnetic core (Fe3O4), which is fabricated using cetyltrimethylammonium bromide (CTAB) as pore-forming agents, tetraethyl orthosilicate (TEOS) as silicon source through a sol–gel process. Compared with...

Ionic-Liquid-Grafted Rigid Poly(p-Phenylene) Microspheres Efficient Heterogeneous Media for Metal Scavenging and Catalysis
Novel guanidinium ionic liquid-grafted rigid poly(p-phenylene) (PPPIL) microspheres have been developed for metal scavenging and catalysis. The noble-metal nanoparticles supported on the microspheres surface can be used as efficient heterogeneous catalysts. The combination of nanoparticles and ionic liquid fragments on the microsphere surfaces enhance the activity and...

Oxygen electroreduction promoted by quasi oxygen vacancies in metal oxide nanoparticles prepared by photoinduced chlorine doping
Quasi oxygen-deficient indium tin oxide nanoparticles (ITO NPs) were prepared by photoinduced chlorine doping, and exhibited much enhanced electrocatalytic activity for oxygen reduction reaction (ORR) in alkaline media, as compared with pristine ITO.

Regio-selective synthesis of polyepichlorohydrin diol using Zn–Co(III) double metal cyanide complex
A simple one-pot ring-opening polymerization (ROP) of epichlorohydrin (ECH) was successfully performed by a heterogeneous Zn–Co(III) double metal cyanide complex (Zn–Co(III) DMCC) catalyst, affording regioregular poly(ECH) diol with a head-to-tail content of >99% in the absence of organic solvent and/or protic compound. No cyclic or oligomer by-product was observed, and the e...

Alternating copolymerization of carbonyl sulfide and Cyclohexene Oxide catalyzed by zinc–cobalt double metal cyanide complex
This paper describes the first example of alternating copolymerization of carbonyl sulfide (COS) with cyclohexene oxide (CHO) via heterogenous catalysis of a nano-lamellar zincecobalt(III) double metal cyanide complex (ZneCo(III) DMCC), providing an efficient method for converting COS to poly(cyclohexene monothiocarbonate) (PCHMTC) with an alternating degree up to 93%. The number-avera...

Hydrophilic PVA-co-PE nanofiber membrane functionalized with iminodiacetic acid by solid-phase synthesis for heavy metal ions removal
A novel hydrophilic poly(vinyl alcohol-co-ethylene) (PVA-co-PE) nanofiber membrane for heavy metal
ions removal was fabricated by the solid phase synthesis of iminodiacetic acid (IDA) on nanofiber
membrane surfaces. The hydrophilic PVA-co-PE nanofiber membranes were activated with cyanuric chloride.
The IDA was then covalently linked to the activated PVA-co-PE nanofiber membranes. The chemical
str...

Studies on Synthesis of Water-Soluble Polymer-supported Transition Metal Polypyridyl Complexes and their interaction with DNA
Five water-soluble polymer-supported transition metal
polypyridyl complexes were synthesized from polyacrylic acid -co-
N-vinyl pyrrolidone, 2-methyl-3-hydroxyl benzaldehyde, o-phenanthroline and
metal acetate salts. Infrared spectra (IR), thermo-gravimetric and differential
thermal analysis (TG-DTA), Inductance Coupling Plasma (ICP) and X-ray
photoelectron spectroscopy (XPS) measurement technolog...

[Macro. Chem. Phys.] Catalytic Precision Polymerization: Rare Earth Metal-Mediated Synthesis of Homopolymers, Block Copolymers, and Polymer Brushes
Recent studies have shown that rare earth metal-mediated group transfer polymerization
(REM-GTP) can be applied to a variety of polar monomers, besides the classic (meth)-
acrylates or (meth)acrylamides, giving access to new polymeric materials. This article
highlights progress in this new fi eld and gives a current overview of the initiation and
propagation of vinylphosphonates, the extension to ...
