Published: October 2016

AbstractTo understand the role of functional groups (FGs) and defects in improving the antipoisoning performance of platinum catalysts for formate oxidation, four kinds of supports originating from carbon nanotubes (CNTs) with varying amounts of FGs and varying degrees of defects are discussed. Platinum particles with controlled similarity are deposited onto the four supports to precisely compare the differences between the four supports. The catalysts structures are characterized by XRD, high‐resolution TEM, Raman spectroscopy, and XPS. The electrochemical performances of the four catalysts are characterized by cyclic voltammetry and chronoamperometry methods. The results show that the use of fully unzipped CNTs, with a higher degree of defects and lower amount of FGs, as a support results in the greatest improvement in antipoisoning performance of platinum, relative to oxidized CNTs with a higher amount of FGs and lower degree of defects. These results indicate that CNT defects play a greater role in promoting the antipoisoning performance of supported catalysts than FGs. These results are helpful to guide the design of supports to improve the antipoisoning performance of formate oxidation catalysts.

AbstractThe quasibinary section of the intermetallic phases MAl4 and MGa4 with M=Sr and Ba have been characterised by means of X‐ray diffraction (XRD) studies and differential thermal analysis. The binary phases show complete miscibility and form solid solutions M(Al1−xGax)4 with M=Sr and Ba. These structures crystallise in the BaAl4 structure type with four‐ and five‐bonded Al and/or Ga atoms (denoted as Al(4b), Al(5b), Ga(4b), and Ga(5b), respectively) that form a polyanionic Al/Ga sublattice. Solid state 27Al NMR spectroscopic analysis and quantum mechanical (QM) calculations were applied to study the bonding of the Al centres and the influence of Al/Ga substitution, especially in the regimes with low degrees of substitution. M(Al1−xGax)4 with M=Sr and Ba and 0.925≤x≤0.975 can be described as a matrix of the binary majority compound in which a low amount of the Ga atoms has been substituted by Al atoms. In good agreement with the QM calculations, 27Al NMR investigations and single crystal XRD studies prove a preferred occupancy of Al(4b) for these substitution regimes. Furthermore, two different local Al environments were found, namely isolated Al(4b1) atoms and Al(4b2), due to the formation of Al(4b)–Al(4b) pairs besides isolated Al(4b) atoms within the polyanionic sublattice. QM calculations of the electric field gradient (EFG) using superlattice structures under periodic boundary conditions are in good agreement with the NMR spectroscopic results.
The Rich Tautomeric Behavior of Campestarenes

Published: October 2016

AbstractCampestarenes are a new family of Schiff‐base macrocycles that form selectively in a one‐step synthesis. These macrocycles with five‐fold symmetry show solvent‐dependent tautomerization and dimerization or aggregation. In this paper, we have prepared new soluble campestarenes that do not aggregate. The initial single‐crystal X‐ray diffraction study of a campestarene reveals that these macrocycles are nearly flat. The tautomeric behavior of the campestarenes has been extensively studied by variable‐temperature, multinuclear NMR spectroscopy, UV/Vis spectroscopy, and IR spectroscopy. In polar solvents, such as DMF, the molecules exist predominantly in their keto‐enamine form, but the enol‐imine tautomer is dominant in non‐polar solvents. A detailed computational study of the tautomeric forms of campestarenes provides a theoretical basis for their behavior and corroborates the experimental data. The results of this study give the first comprehensive understanding of the electronic and spectroscopic properties of these pentagonal macrocycles.
Exploring the (Very Flat) Potential Energy Landscape of R−Br⋅⋅⋅π Interactions with Accurate CCSD(T) and SAPT Techniques

Published: October 2016

AbstractHalogen bonds involving an aromatic moiety as an acceptor, otherwise known as R−X⋅⋅⋅π interactions, have increasingly been recognized as being important in materials and in protein–ligand complexes. These types of interactions have been the subject of many recent investigations, but little is known about the ways in which the strengths of R−X⋅⋅⋅π interactions vary as a function of the relative geometries of the interacting pairs. Here we use the accurate CCSD(T) and SAPT2+3δMP2 methods to investigate the potential energy landscapes for systems of HBr, HCCBr, and NCBr complexed with benzene. It is found that only the separation between the complexed molecules have a strong effect on interaction strength while other geometric parameters, such as tilting and shifting R−Br⋅⋅⋅π donor relative to the benzene plane, affect these interactions only mildly. Importantly, it is found that the C6v (T‐shaped) configuration is not the global minimum for any of the dimers investigated.

Published: October 2016

AbstractTwo new 6,13‐disubstituted pentacene derivatives, 1 c and 1 d, with alkyl and triisopropylsilylethynyl substitution have been synthesized and characterized experimentally and computationally. The alkyl substituted 1 c and 1 d represent the first 6‐alkyl‐substituted pentacene derivative where the fully aromatic species dominates over the corresponding tautomer. Indeed, no tautomerization product is found for either 1 c or 1 d upon heating or in the presence of catalytic amounts of acid. On the other hand, an unexpected dimer (3 c) is formed from 1 c. A plausible mechanism for this new dimerization process of the 6‐methyl‐substituted pentacene derivative 1 c is proposed, which involves first a bimolecular hydrogen atom transfer followed by an intramolecular [4+2] Diels–Alder cycloaddition. In the case of 6‐butyl substitution, neither tautomerization nor dimerization is observed. Computations support the proposed 1 c dehydrodimerization pathway, explain why 1 d does not dimerize, and show the importance of the nature of the group at C‐13 in controlling the relative stability of 6‐alkyl‐substituted pentacene tautomers.

AbstractThe first synthesis of pure Rh1−xCux solid‐solution nanoparticles is reported. In contrast to the bulk state, the solid‐solution phase was stable up to 750 °C. Based on facile density‐functional calculations, we made a prediction that the catalytic activity of Rh1−xCux can be maintained even with 50 at % replacement of Rh with Cu. The prediction was confirmed for the catalytic activities on CO and NOx conversions.

AbstractA limited understanding of how variation in the species composition among communities (i.e., β‐diversity) changes along natural environmental gradients, and the mechanisms responsible, inhibits our ability to understand large‐scale biodiversity change resulting from either natural or anthropogenic drivers. Therefore, our aim was to test key drivers of β‐diversity patterns along a strong, natural environmental gradient for seven widely different organisms groups, that is, root‐associated fungi, litter fungi, soil nematodes, vascular plants, epiphytic lichens, beetles, and spiders. Using previously published community‐level data from boreal‐forested islands, we calculated α‐diversity and β‐diversity for each of the seven organism groups. Out of several available environmental variables, we identified four variables, that is, ecosystem age, total C storage, net primary productivity (NPP), and N‐to‐P ratio, as potential predictors of variation in β‐diversity. We found that ecosystem age was the variable with the highest overall importance. We then used two different methods to quantify the relative importance of stochastic and deterministic processes underlying patterns in β‐diversity along the ecosystem age gradient, and our detailed knowledge based on prior data collection in the study system to mechanistically explain among‐group differences in these patterns. We found divergent responses in β‐diversity along the age gradient for the seven different organism groups, due to among‐group differences in the relative importance of deterministic vs. stochastic community assembly, and attributed these results to reliance on resources from different energy channels that are not always related to NPP. Our results highlight the necessity to consider the importance of taxon‐specific resources, and not only NPP, to obtain an understanding of β‐diversity patterns among organism groups and ecosystems, as well as large‐scale patterns in biodiversity. They therefore also suggest that management and protection of β‐biodiversity in the landscape requires explicit consideration of a wide range of habitats.
Price Changes in Regulated Healthcare Markets: Do Public Hospitals Respond and How?

Published: October 2016

AbstractThis paper examines the behaviour of public hospitals in response to the average payment incentives created by price changes for patients classified in different diagnosis‐related groups (DRGs). Using panel data on public hospitals located within the Italian region of Emilia‐Romagna, we test whether a 1‐year increase in DRG prices induced public hospitals to increase their volume of activity and whether a potential response is associated with changes in waiting times and/or length of stay. We find that public hospitals reacted to the policy change by increasing the number of patients with surgical treatments. This effect was smaller in the 2 years after the policy change than in later years, and for providers with a lower excess capacity in the pre‐policy period, whereas it did not vary significantly across hospitals according to their degree of financial and administrative autonomy. For patients with medical DRGs, instead, there appeared to be no effect on inpatient volumes. Our estimates also suggest that an increase in DRG prices had no impact on the proportion of patients waiting more than 6 months. Finally, we find no evidence of a significant effect on patients' average length of stay. Copyright © 2016 John Wiley & Sons, Ltd.
