Triphenylamine Groups Improve Blocking Behavior of Phenoxazine Dyes in Cobalt‐Electrolyte‐Based Dye‐Sensitized Solar Cells

Published: August 2014

AbstractNovel phenoxazine dyes are successfully introduced as sensitizers into dye‐sensitized solar cells (DSCs) with cobalt‐based electrolyte. In sensitizers with triphenylamine (TPA) groups recombination from electrons in the TiO2 conduction band to the cobalt(III) species is suppressed. The effect of the steric properties of the phenoxazine sensitizers on the overall device performance and on recombination and regeneration processes is compared. Optimized DSCs sensitized with IB2 having two TPA groups in combination with tris(2,2′‐bipyridyl) cobalt(II/III) yield efficiencies of 6.3 %, similar to that of IB3, which is equipped with mutiple alkoxy groups. TH310 with only one TPA group gives lower efficiency and open circuit voltage, while IB1 without TPA groups performs even worse. These results demonstrate that both TPA groups on the IB2 are needed for an efficient blocking effect. These results reveal a possible new role for TPA units in DSC sensitizer design.

AbstractCatalytic hydrogenation of organic carboxylic acids and their esters, for example, cellulosic ethanol from fermentation of acetic acid and hydrogenation of ethyl acetate is a promising possibility for future biorefinery concepts. A hybrid conversion process based on selective hydrogenation of butyric acid combined with fermentation of glucose has been developed for producing biobutanol. ZnO‐supported Ru–Sn bimetallic catalysts exhibits unprecedentedly superior performance in the vapor‐phase hydrogenation of biomass‐derived butyric acid to n‐butanol (>98 % yield) for 3500 h without deactivation.

Published: August 2014

AbstractThe synthesis of buta‐1,3‐diene from ethanol has been studied over metal‐containing (M=Ag, Cu, Ni) oxide catalysts (MOx=MgO, ZrO2, Nb2O5, TiO2, Al2O3) supported on silica. Kinetic study of a wide range of ethanol conversions (2–90 %) allowed the main reaction pathways leading to butadiene and byproducts to be determined. The key reaction steps of butadiene synthesis were found to involve ethanol dehydrogenation, acetaldehyde condensation, and the reduction of crotonaldehyde with ethanol into crotyl alcohol. Catalyst design included the selection of active components for each key reaction step and merging of these components into multifunctional catalysts and adjusting the catalyst functions to achieve the highest selectivity. The best catalytic performance was achieved over the Ag/ZrO2/SiO2 catalyst, which showed the highest selectivity towards butadiene (74 mol %).

Published: August 2014

AbstractA library of 20 UiO‐66‐derived metal–organic frameworks (MOFs) is synthesized in a combinatorial approach involving mixed ligand copolymerization and two post‐synthetic modifications (PSMs) in tandem. Mixed ligand co‐polymerization of benzene‐1,4‐dicarboxylic acid (BDC) and sodium 2‐sulfoterephthalate (SS‐BDC) with zirconium tetrachloride (ZrCl4) was used to prepare 5 groups of MOFs with the same UiO‐66 topology but differing amounts of sulfate groups. These MOFs exhibit excellent water stabilities in a pH range of 1 to 12, together with high CO2 uptake capacities and selectivities.

Published: August 2014

ABSTRACTSprouty (Spry) proteins are negative feedback inhibitors of receptor tyrosine kinase signaling. Downregulation of Spry2 has been demonstrated to promote elongative axon growth of cultured peripheral and central neurons. Here, we analyzed Spry2 global knockout mice with respect to axon outgrowth in vitro and peripheral axon regeneration in vivo. Neurons dissociated from adult Spry2 deficient sensory ganglia revealed stronger extracellular signal‐regulated kinase activation and enhanced axon outgrowth. Prominent axon elongation was observed in heterozygous Spry2+/− neuron cultures, whereas homozygous Spry2−/− neurons predominantly exhibited a branching phenotype. Following sciatic nerve crush, Spry2+/− mice recovered faster in motor but not sensory testing paradigms (Spry2−/− mice did not tolerate anesthesia required for nerve surgery). We attribute the improvement in the rotarod test to higher numbers of myelinated fibers in the regenerating sciatic nerve, higher densities of motor endplates in hind limb muscles and increased levels of GAP‐43 mRNA, a downstream target of extracellular regulated kinase signaling. Conversely, homozygous Spry2−/− mice revealed enhanced mechanosensory function (von Frey's test) that was accompanied by an increased innervation of the epidermis, elevated numbers of nonmyelinated axons and more IB4‐positive neurons in dorsal root ganglia. The present results corroborate the functional significance of receptor tyrosine kinase signaling inhibitors for axon outgrowth during development and nerve regeneration and propose Spry2 as a novel potential target for pharmacological inhibition to accelerate long‐distance axon regeneration in injured peripheral nerves. © 2014 Wiley Periodicals, Inc.

Can phenotypic rescue from harvest refuges buffer wild sheep from selective hunting?
Authors: Pelletier Fanie , Festa‐Bianchet Marco , Jorgenson Jon T. , Feder Chiarastella , Hubbs Anne 
Published: August 2014

AbstractHuman harvests can unwittingly drive evolution on morphology and life history, and these selective effects may be detrimental to the management of natural resources. Although theory suggests that harvest refuges, as sources of unselected animals, could buffer the effects of human exploitation on wild populations, few studies have assessed their efficiency. We analyzed records from >7000 trophy bighorn rams (Ovis canadensis) harvested in Alberta, Canada, between 1974 and 2011 to investigate if the movement of rams from refuges toward harvested areas reduced the effects of selective harvesting on horn size through phenotypic rescue. Rams taken near refuges had horns on average about 3% longer than rams shot far from refuges and were slightly older, suggesting migration from refuges into hunted areas. Rams from areas adjacent to and far from harvest refuges, however, showed similar declines in horn length and increases in age at harvest over time, indicating a decreasing rate of horn growth. Our study suggests that the influx of rams from refuges is not sufficient to mitigate the selective effects of sheep trophy harvest. Instead, we suggest that selective hunting of highly mobile animals may affect the genetic structure of populations that spend part of the year inside protected areas.

Published: August 2014

AbstractEuropium(III) and terbium(III) complexes have been prepared using the ligands 2‐(4,5‐dihydro‐1,3‐oxazol‐2‐yl)phenol (HL1) and 2‐(4,5‐dihydro‐1,3‐thiazol‐2‐yl)phenol (HL2) in yields ranging between 74 and 100 %. Metal‐to‐ligand ratios of 1:3 and 1:4 can be achieved, giving rise to compounds with the formulae [Ln2(L)6] and NR4[Ln(L)4], Ln = Eu, Tb. Recrystallisation of the complexes from DMSO resulted in the formation of octanuclear complexes [Na2(Ln(L1)3)2(CO3)(DMSO)2]2 held tightly together by carbonate ions that have been formed from CO2 from the atmosphere. Five structures have been determined, showing a bidentate binding mode of the ligand through the phenolate oxygen and the nitrogen atom of the five‐membered ring. Most terbium compounds show bright luminescence upon excitation with near‐UV radiation, with quantum yields of 16 % to 79 %. Strong emission is observed for NBu4[Eu(L1)4] and NEt4[Eu(L2)4] with quantum yields of 43 % and 20 %, respectively.
Managing one's social identity: Successful and unsuccessful identity management
Authors: Martiny Sarah E. , Kessler Thomas 
Published: August 2014

AbstractThis work explores the motivational dynamics of social identity management. Following social identity theory, we hypothesized that a threat to a positive social identity elicits specific negative emotions (i.e., outgroup‐directed anger) and motivates identity management. Successful identity management restores a positive social identity and decreases outgroup‐directed anger. However, when a successful identity management is blocked (e.g., because of limited cognitive resources), identity management will be unsuccessful and outgroup‐directed anger will remain at a higher level. This effect of unsuccessful identity management on outgroup‐directed anger should be particularly strong for group members who highly value their group (i.e., high group‐based self‐esteem). A negative comparison outcome is discrepant with these group members' positive view of the ingroup, and therefore, unsuccessful identity management should especially elicit negative emotions (i.e., anger) towards the threatening outgroup. Two studies tested these predictions. Study 1 (N = 110) showed that participants' outgroup‐directed anger increased when threatened under cognitive load. Study 2 (N = 99) demonstrated that this was particularly true for participants high in group‐based self‐esteem. The results' implications for research on the motivational processes underlying social identity management are discussed. Copyright © 2014 John Wiley & Sons, Ltd.
Assessment of the usefulness of particle size distribution measured by laser diffraction for soil water retention modelling

Published: August 2014

AbstractParticle size distribution (PSD) is a major soil characteristic, which is essential and commonly used for the development of pedotransfer functions (PTFs) to estimate the water retention of soils. The laser diffraction method (LDM) became a popular alternative to the standard sieve‐hydrometer method (SHM) of PSD measurement. Unfortunately, PSDs determined with LDM and SHM methods differ sometimes substantially. Moreover, it is claimed that the laser diffraction method underestimates finer fractions in favor of coarser fractions. Several authors have tried to elaborate on methods to recalculate LDM PSD into its SHM counterparts, but no universal methodology has been developed to this date. In this paper, we use PSD determined by LDM directly for PTF development and compare it with the classical PTF approach based on PSD measured by SHM. Four different PTF models based on LDM particle size distribution data were developed, with different PSD characteristics taken as the models' input variables. The possibility of using alternative PSD characteristics, such as deciles, area moment mean and volume moment mean, for PTF development was examined. The accuracy of PTF models constructed on the basis of LDM‐measured PSD was comparable with that of the developed models using texture data obtained from SHM, giving approximately the same RMSE and R2 values. Our study shows that LDM‐measured particle size distribution may be directly used for PTF developments without any recalculations to their sieve‐hydrometer counterparts.
Techniques to measure sorption and migration between small molecules and packaging. A critical review
Authors: Kadam Ashish A , Karbowiak Thomas , Voilley Andrée , Debeaufort Frédéric 
Published: August 2014

AbstractThe mass transfer parameters diffusion and sorption in food and packaging or between them are the key parameters for assessing a food product's shelf‐life in reference to consumer safety. This has become of paramount importance owing to the legislations set by the regulated markets. The technical capabilities that can be exploited for analyzing product–package interactions have been growing rapidly. Different techniques categorized according to the state of the diffusant (gas or liquid) in contact with the packaging material are emphasized in this review. Depending on the diffusant and on the analytical question under review, the different ways to study sorption and/or migration are presented and compared. Some examples have been suggested to reach the best possible choice, consisting of a single technique or a combination of different approaches. © 2014 Society of Chemical Industry
