Property reinforcement of acrylonitrile‐butadiene‐styrene by simultaneous incorporation of carbon nanotubes and self‐prepared copper particles
Authors: Wang Gen Lin , Duan Lei , Ding Ke Hong , Zhang Ming 
Published: December 2014

ABSTRACTIn this article, copper (Cu) crystallites were successfully prepared via low temperature molten salt method, and the possible formation mechanisms were proposed. The conductive fillers of multiwalled carbon nanotubes (MWCNTs) and as‐prepared Cu particles were designed and introduced into acrylonitrile‐butadiene‐styrene (ABS) blend to prepare different conductive composites. The dispersion states of conductive fillers and the morphologies of the composites were characterized using a field emission scanning electron microscope. The electrical resistivity of different composites was measured. The results showed that Cu and MWCNTs exhibited a synergistic effect in decreasing the electrical resistivity of the Cu/MWCNTs/ABS composites, because Cu that could locate between MWCNTs chain segments provides a better charge transport in the conductive pathways. Compared with pure ABS, the tensile strength, elastic modulus and thermal stability of the Cu/MWCNTs/ABS composites were significantly improved with the incorporation of Cu and MWCNTs. © 2014 Wiley Periodicals, Inc.

Is There a Role for Social Pensions in Asia?
Authors: Barrientos Armando 
Published: December 2014

AbstractRapid population ageing and economic transformation in Asia underline the policy challenges associated with ensuring income security in old age. This article examines the potential role of social pensions in securing old‐age income security in Asia. It assesses the main policy trade‐offs associated with adopting alternative social pension designs, especially around two critical policy points: the comparative advantages of social assistance and social pensions; and the integration of non‐contributory transfers within advanced contributory pension schemes.

Published: December 2014

AbstractThe use of pyridine‐2,4‐dicarboxylic acid (H2pydc) in the construction of SrII and SrII‐MII (M=Co, Ni, Zn and Cu) coordination polymers is reported. Eight complexes, that is, [Sr(pydc)H2O]n (1), [MSr(pydc)2(H2O)2]n (M=Co (2), Ni (3), Zn (4)), [ZnSr(pydc)2(H2O)7]n⋅4 nH2O (5), [SrCu(pydc)2]n (6), [SrCu(pydc)2(H2O)3]n⋅2 nH2O (7), and [Cu3Sr2(pydc)4(Hpydc)2(H2O)2]n (8), have been synthesized via dexterously choosing the appropriate strontium sources and transition metal salts, and rationally controlling the temperature of the reaction systems. Complexes 1, 2 (3, 4), 6, and 8 display four types of 3‐D framework structures. Complexes 5 and 7 exhibit a 2‐D network and a 1‐D chain structure, respectively. The 2‐D complex 7 can be reversibly transformed into 3‐D compound 6 through temperature‐induced solvent‐mediated structural transformation. The luminescent property studies indicated that complex 1 shows a strong purple luminescent emission and 4 exhibits a strong violet luminescence emission. The magnetic properties of 2, 3, and 8 were also studied. Antiferromagnetic MII⋅⋅⋅MII interactions were determined for these complexes.
Alpinetin enhances cholesterol efflux and inhibits lipid accumulation in oxidized low‐density lipoprotein‐loaded human macrophages
Authors: Jiang Zhengming , Sang Haiqiang , Fu Xin , Liang Ying , Li Ling 
Published: December 2014

AbstractAlpinetin is a natural flavonoid abundantly present in the ginger family. Here, we investigated the effect of alpinetin on cholesterol efflux and lipid accumulation in oxidized low‐density lipoprotein (ox‐LDL)‐treated THP‐1 macrophages and human peripheral blood monocyte‐derived macrophages (HMDMs). After exposing THP‐1 macrophages to alpinetin, cholesterol efflux was determined by liquid scintillator. The mRNA and protein levels of peroxisome proliferator‐activated receptor gamma (PPAR‐), liver X receptor alpha (LXR‐α), ATP‐binding cassette transporter A1 (ABCA1), and ABCG1 and scavenger receptor class B member 1 were determined by reverse‐transcriptase PCR (RT‐PCR) and Western blot analysis, respectively. Alpinetin promoted apolipoprotein A‐I‐ and high‐density‐lipoprotein‐mediated cholesterol efflux and elevated PPAR‐γ and LXR‐α mRNA and protein expression in a dose‐dependent fashion in ox‐LDL‐treated THP‐1 macrophages and HMDMs. Small interfering RNA‐mediated silencing of PPAR‐γ or LXR‐α dose dependently reversed alpinetin‐increased cholesterol efflux in THP‐1 macrophages, indicating the involvement of PPAR‐γ and LXR‐α in alpinetin‐promoted cholesterol efflux. Alpinetin inhibited ox‐LDL‐induced lipid accumulation and enhanced the expression of ABCA1 and ABCG1 mRNA and protein, which was reversed by specific knockdown of PPAR‐γ or LXR‐α. Taken together, our results reveal that alpinetin exhibits positive effects on cholesterol efflux and inhibits ox‐LDL‐induced lipid accumulation, which might be through PPAR‐/LXR‐/ABCA1/ABCG1 pathway.
Ultra‐Thin Hollow Carbon Nanospheres for Pseudocapacitive Sodium‐Ion Storage
Authors: Yun Young Soo , Cho Se Youn , Kim Haegyeom , Jin Hyoung‐Joon , Kang Kisuk 
Published: December 2014

AbstractUltra‐thin hollow carbon nanospheres (UTH‐CNs) are fabricated for use as anodes of asymmetric sodium ion pseudocapacitors. The ∼3 nm thick amorphous carbon walls obtained from regenerated silk proteins as a template exhibit a well‐defined porous structure suitable for reversible sodium‐ion storage. The UTH‐CNs show remarkable electrochemical activity with sodium via a pseudocapacitive reaction, delivering a large reversible capacity as well as superior rate performance for more than 1000 cycles. The pseudocapacitors based on UTH‐CNs exhibit a capacitance of 186 F g−1, a specific energy of 43 Wh kg−1 and a power density of 10 kW kg−1. This represents the highest value yet reported for asymmetric sodium‐ion storage pseudocapacitors.
Atropisomeric [(diphosphine)Au2Cl2] Complexes and their Catalytic Activity Towards Asymmetric Cycloisomerisation of 1,6‐Enynes
Authors: Barreiro Elena M. , Boltukhina Ekaterina V. , White Andrew J. P. , Hii King Kuok (Mimi) 
Published: December 2014

AbstractX‐ray crystal structures of two [(diphosphine)Au2Cl2] complexes (in which diphosphine=P‐Phos and xylyl‐P‐Phos; P‐Phos=[2,2′,6,6′‐Tetramethoxy‐4,4′‐bis(diphenylphosphino)‐3,3′‐bipyridine]) were determined and compared to the reported structures of similar atropisomeric gold complexes. Correlations between the Au⋅⋅⋅Au distances and torsional angles for the biaryl series of ligands (MeOBIPHEP, SEGPhos, and P‐Phos; BIPHEP=2,2′‐bis(diphenylphosphino)‐1,1′‐biphenyl, SEGPhos=[(4,4′‐bi‐1,3‐benzodioxole)‐5,5′‐diyl]bis[diphenylphosphine]) can be made; these measurements appear to be very dependent upon the phosphorous substituent. Conversely, the same effect was not observed for ligands based on the binaphthyl (BINAP) series. The catalytic activity of these complexes was subsequently assessed in the enantioselective cycloisomerisation of 1,6‐enynes and revealed an over‐riding electronic effect: more‐electron‐rich phosphines promote greater enantioselectivity. The possibility of silver acting as a (co‐)catalyst was ruled out in these reactions.
The Effect of the Spacer of Bis(biurea) Ligands on the Structure of A2L3‐type (A=anion) Phosphate Complexes

Published: December 2014

AbstractBy tuning the length and rigidity of the spacer of bis(biurea) ligands L, three structural motifs of the A2L3 complexes (A represents anion, here orthophosphate PO43−), namely helicate, mesocate, and mono‐bridged motif, have been assembled by coordination of the ligand to phosphate anion. Crystal structure analysis indicated that in the three complexes, each of the phosphate ions is coordinated by twelve hydrogen bonds from six surrounding urea groups. The anion coordination properties in solution have also been studied. The results further demonstrate the coordination behavior of phosphate ion, which shows strong tendency for coordination saturation and geometrical preference, thus allowing for the assembly of novel anion coordination‐based structures as in transition‐metal complexes.

AbstractA new series of neutral isocyanoborato rhenium(I) diimine complexes [Re(CO)3(N^N)(CNBR3)], where N^N=bpy, 4,4′‐Me2bpy, phen, 4,7‐Me2phen, 2,9‐Me2phen, 3,4,7,8‐Me4phen; R=C6F5, C6H5, Cl, 4‐ClC6H4, 3,5‐(CF3)2C6H3, with various isocyanoborate and diimine ligands of diverse electronic and steric nature have been synthesized and characterized. The X‐ray crystal structures of six complexes have also been determined. These complexes displayed intense bluish green to yellow phosphorescence at room temperature in dichloromethane solution. The photophysical and electrochemical properties of these complexes had been investigated. To elucidate the electronic structures and transitions of these complexes, DFT and TD‐DFT calculations have been performed, which revealed that the lowest‐energy electronic transition associated with these complexes originates from a mixture of MLCT [dπ(Re)→π*(N^N)] and LLCT [π(CNBR3)→π*(N^N)] transitions.
Growth of Hydrophilic CuS Nanowires via DNA‐Mediated Self‐Assembly Process and Their Use in Fabricating Smart Hybrid Films for Adjustable Chemical Release
Authors: Zhou Li , Li Wei , Chen Zhaowei , Ju Enguo , Ren Jinsong , Qu Xiaogang 
Published: December 2014

AbstractFacile growth of CuS nanowires through self‐assembly and their application as building blocks for near‐infrared light‐responsive functional films have been demonstrated. It is found that DNA is a key factor in preparing the CuS material with defined nanostructure. An exclusive oriented self‐aggregate growth mechanism is proposed for the growth of the nanowires, which might have important implications for preparing advanced, sophisticated nanostructures based on DNA nanotechnology. By employing the hydrophilic CuS nanowire as an optical absorber and thermosensitive nanogel as guest reservoir inside alginate film, a new platform for the release of functional molecules has been set up. In vitro studies have shown that the hybrid film possesses excellent biocompatibility and the release rate of chemical molecules from the film could be controlled with high spatial and temporal precision. Our novel approach and the resulting outstanding combination of properties may advance both the fields of DNA nanotechnology and light‐responsive devices.

Published: December 2014

AbstractFoldamers offer an attractive opportunity for the design of novel molecules that mimic the structures and functions of proteins and enzymes including biocatalysis and biomolecular recognition. Herein we report a new class of nonnatural helical sulfono‐γ‐AApeptide foldamers of varying lengths. The crystal structure of the sulfono‐γ‐AApeptide monomer S6 illustrates the intrinsic folding propensity of sulfono‐γ‐AApeptides, which likely originates from the bulkiness of tertiary sulfonamide moiety. The two‐dimensional solution NMR spectroscopy data for the longest sequence S1 demonstrates a 10/16 right‐handed helical structure. Optical analysis using circular dichroism further supports well‐ defined helical conformation of sulfono‐γ‐AApeptides in solution containing as few as five building blocks. Future development of sulfono‐γ‐AApeptides may lead to new foldamers with discrete functions, enabling expanded application in chemical biology and biomedical sciences.
