Metal-Free Route to Precise Synthesis of Poly(propylene oxide) and Its Blocks with High Activity
关键字：Metal-Free,propylene oxide,High Activity
The fast and living ring-opening polymerization (ROP) of propylene oxide (PO) by metal-free catalysis is reported. By using triethyl borane (TEB) and organic Lewis bases (LBs, e.g.: phosphazene base, amidine and guanidine) as the catalysts, various alkyl alcohols can effectively initiate the ROP of PO, yielding tailor-made poly(propylene oxide)s (PPOs) with high regioregularity, predictable mole...

Nickel metal-organic framework implanted on graphene and incubated to be ultrasmall nickel phosphide nanocrystals acts as a highly efficient water splitting electrocatalyst
关键字：MOF，water splitting electrocatalyst
The development of low-cost, efficient, and stable electrocatalysts with bifunctional catalytic activity for overall water splitting is desirable but remains a great challenge. Here, a template-confinement strategy is presented with nickel metal–organic framework (MOF-74-Ni) implanted on graphene oxide and incubated by low temperature phosphorization to become ultrasmall nickel phosphide nanocr...

(JPS Part A) Poly(vinylphosphonate)s functionalized polymer microspheres via rare earth metal-mediated group transfer polymerization
关键字：fracture; group transfer polymerization; microspheres;
We demonstrate a facile, yet efficient method for the
functionalization of crosslinked polystyrene (PS) microspheres
with biocompatible poly(vinylphosphonate)s via the combination
of a UV grafting polymerization and a surface-initiated group
transfer polymerization. Self-initiated photografting and photopolymerization
of ethylene glycol dimethacrylate results in direct
photografting of poly(ethyle...

Application of Micro or Nano-sized Natural Polymeric Adsorbents in Heavy Metal Treatments
关键字：Chitin or chitosan nanofibrils，protein microspheres，heavy metals，biosorption，sorption behavior
Toxic heavy metal species are mobilized from industrial activities and fossil fuel consumption
and eventually are bioaccumulated through the food chain, leading to both ecological and health
problems. Recently, micro or nanoscopic materials including microspheres, nanobeads,
nanocomposites, magnetic nano adsorbents, and nanofibrous matrices, are of great interests to be
developed as efficient ...
