Cellulose Functionalization via ATRP Grafting of Glycidyl Methacrylate for Cr(VI) Adsorption
Authors: Lin Chunxiang , Qiao Sha , Liu Danhui , Liu Minghua 
Published: November 2013

AbstractCellulose was first grafted with glycidyl methacrylate (GMA) in an ionic liquid via atom transfer radical polymerization (ATRP) and then the introduced epoxy groups were reacted with ethanediamine (EDA) to obtain an amino adsorbent. The grafting copolymer and the obtained adsorbent were characterized by FTIR,1H NMR, TEM and SEM. The results showed that the grafted copolymers had grafted polymer chains with well‐controlled molecular weight and polydispersity, the polymerization was a controlled system. The cellulose adsorbent had numerous micropores on the surface and showed high performance for Cr(VI) adsorption. The adsorption behavior was pH dependent and the sorption equilibrium was achieved within 2 h on the adsorbent.

Intraspecific phenotypic variation in a fish predator affects multitrophic lake metacommunity structure
Authors: Howeth Jennifer G. , Weis Jerome J. , Brodersen Jakob , Hatton Elizabeth C. , Post David M. 
Published: November 2013

AbstractContemporary insights from evolutionary ecology suggest that population divergence in ecologically important traits within predators can generate diversifying ecological selection on local community structure. Many studies acknowledging these effects of intraspecific variation assume that local populations are situated in communities that are unconnected to similar communities within a shared region. Recent work from metacommunity ecology suggests that species dispersal among communities can also influence species diversity and composition but can depend upon the relative importance of the local environment. Here, we study the relative effects of intraspecific phenotypic variation in a fish predator and spatial processes related to plankton species dispersal on multitrophic lake plankton metacommunity structure. Intraspecific diversification in foraging traits and residence time of the planktivorous fish alewife (Alosa pseudoharengus) among coastal lakes yields lake metacommunities supporting three lake types which differ in the phenotype and incidence of alewife: lakes with anadromous, landlocked, or no alewives. In coastal lakes, plankton community composition was attributed to dispersal versus local environmental predictors, including intraspecific variation in alewives. Local and beta diversity of zooplankton and phytoplankton was additionally measured in response to intraspecific variation in alewives. Zooplankton communities were structured by species sorting, with a strong influence of intraspecific variation in A. pseudoharengus. Intraspecific variation altered zooplankton species richness and beta diversity, where lake communities with landlocked alewives exhibited intermediate richness between lakes with anadromous alewives and without alewives, and greater community similarity. Phytoplankton diversity, in contrast, was highest in lakes with landlocked alewives. The results indicate that plankton dispersal in the region supplied a migrant pool that was strongly structured by intraspecific variation in alewives. This is one of the first studies to demonstrate that intraspecific phenotypic variation in a predator can maintain contrasting patterns of multitrophic diversity in metacommunities.

AbstractThe synthesis and structural characterization of a series of late‐transition‐metal and divalent lanthanide complexes derived from 2‐quinolyl‐linked phosphoranosulfide CH2(iPr2P=S)(C9H6N‐2) are reported. Metathesis of dimeric lithium complex [(Li{Et2O}{CH(iPr2P–S)(C9H6N‐2)})2] (1) with CoCl2 (2 equiv.) afforded a heteroleptic cobalt(II) complex [(CoCl{CH(iPr2P=S)2(C9H6N‐2)})2] (2). Treatment of potassium complex [(K{CH(iPr2P–S)(C9H6N‐2)})n] (3) with MCl2 (M = Mn, Fe, Co; 1 equiv.) afforded homoleptic 2‐quinolyl‐linked (thiophosphorano)methanide metal(II) complexes, [M{CH(iPr2P–S)2(C9H6N‐2)}2] [M = Mn (4), Fe (5), Co (6)]. Metathesis reaction of 3 with [YbI2(thf)2] and [EuI2(thf)2] (1 equiv.) afforded dimeric homoleptic ytterbium(II) complex [(Yb{CH(iPr2P–S)(C9H6N‐2)}2)2] (7) and europium(II) complex [(Eu{CH(iPr2P–S)(C9H6N‐2)}2)2] (8), respectively. The structures of 2 and 4–8 have been determined by X‐ray crystallography. Furthermore, the magnetic susceptibility of compounds 4–6 have been determined by using Evan's method.
