Melt‐grafting mechanism study of maleic anhydride onto polypropylene with 1‐decene as the second monomer
Authors: Lei Caihong , Chen Dahua , Wu Bo , Xu Yunqi , Li Shanliang , Huang Weiliang 
Published: April 2011

AbstractAlthough polypropylene (PP) grafted by maleic anhydride (MAH) has been successfully commercialized, the grafting mechanism under the existence of a second monomer is not very clear. To simulate the grafting process of MAH onto PP with 1‐decene as the second monomer, the MAH/1‐decene copolymer and Alder ene reaction product were prepared and grafted onto PP with dicumyl peroxide as the initiator. We found that the grafting of the copolymer and the reactive product greatly improved the grafting degree of MAH. Particularly, the grafting degree with a 3% content of the Alder ene reactive product was 1.89%, which was 178% higher than that of pure MAH‐g‐PP, the maximum value of which was 0.68%. The molecular weight of the synthesized product affected the grafting efficiency and crystallization behavior of the grafted system. The system grafted with the Alder ene reaction product showed a higher crystallization temperature and crystalline degree. When the molecular weight of the copolymer was higher than 1700, the improvement of the grafting degree could be neglected. For MAH‐g‐PP with 1‐decene as the second monomer, the possible grafting mechanisms were as follows: first, the formation of MAH/1‐decene copolymer or the Alder ene reaction product, and second, the grafting of the previously formed product onto PP, in which, the effect of the Alder ene reaction product was more pronounced. © 2011 Wiley Periodicals, Inc.

Coccolithophorid algae culture in closed photobioreactors
Authors: Moheimani Navid R. , Isdepsky Andreas , Lisec Jan , Raes Eric , Borowitzka Michael A. 
Published: April 2011

AbstractThe feasibility of growth, calcium carbonate and lipid production of the coccolithophorid algae (Prymnesiophyceae), Pleurochrysis carterae, Emiliania huxleyi, and Gephyrocapsa oceanica, was investigated in plate, carboy, airlift, and tubular photobioreactors. The plate photobioreactor was the most promising closed cultivation system. All species could be grown in the carboy photobioreactor. However, P. carterae was the only species which grew in an airlift photobioreactor. Despite several attempts to grow these coccolithophorid species in the tubular photobioreactor (Biocoil), including modification of the airlift and sparger design, no net growth could be achieved. The shear produced by turbulence and bubble effects are the most likely reasons for this failure to grow in the Biocoil. The highest total dry weight, lipid and calcium carbonate productivities achieved by P. carterae in the plate photobioreactors were 0.54, 0.12, and 0.06 g L−1 day−1 respectively. Irrespective of the type of photobioreactor, the productivities were P. carterae > E. huxleyi > G. oceanica. Pleurochrysis carterae lipid (20–25% of dry weight) and calcium carbonate (11–12% of dry weight) contents were also the highest of all species tested. Biotechnol.

Aryl Fluoride Reductive Elimination from PdII Complexes: a Descriptor to Guide Ligand Selection
Authors: Cui Luchao , Saeys Mark 
Published: April 2011

AbstractThe effect of ligand selection on the reductive elimination barrier of PdII aryl fluoride complexes was analyzed by using density functional theory (DFT) calculations. A separate Evans–Polanyi relationship between the activation barriers and the reaction energies is found for CF reductive elimination from monodentate and bis(monodentate) PdII complexes. For comparable reaction energies, the reductive elimination barriers for monodentate complexes [LPd(Ar)F] (L=PR3, Ar=aryl) were calculated to be 80 kJ mol−1 lower than for bis(monodentate) complexes [L2Pd(Ar)F]. Natural population analysis demonstrated that the partial charges on the Pd center and on the aryl α‐carbon can be used as a descriptor for the reductive elimination barriers. The presence of a trans phosphine ligand in bis(monodentate) complexes increases the PdC charge density and hence increases the CF reductive elimination barrier. The importance of the PdC charge density can be understood by performing a natural bond orbital analysis. Indeed, CF reductive elimination is best described as the nucleophilic attack of one of the fluorine lone pairs on the antibonding PdC orbital, and the energy difference between this fluorine lone pair and the antibonding PdC orbital determines the rate of this nucleophilic attack.
Interfacing Colloidal Graphene Oxide Sheets with Gold Nanoparticles

Published: April 2011

AbstractAqueous solutions of graphene oxide (GO) and citrate‐stabilised gold nanoparticles (AuNPs) are two classic, negatively charged colloids. Using the surface plasmon resonance spectra of AuNPs as a probe, we illustrate how the two like‐charged colloids interact with each other and in so doing, reveal the unique solution behaviour of GO. We demonstrate that the electrical double layer of the GO sheets in water plays a key role in controlling the interaction between GO and AuNPs, which displays a one‐way gate effect. It is shown that GO can capture and disperse AuNPs in water in a controllable fashion, without the need for additional chemical linkers. This discovery allows the successful synthesis of uncapped, yet solution‐dispersible metal‐nanoparticle assemblies. Such metal nanostructures have long been pursued for nano‐plasmonics and sensing applications, but have remained difficult to prepare using conventional polymer dispersants. This work also makes clear that the combination of the two‐dimensional conformation of GO along with its large molecular size and self‐contained functional groups allows it to act as a unique soluble nanocarrier/substrate (the thinnest, functionalised flat substrate possible in nature) for the synthesis of new, soluble functional materials.
