ObjectivesThe present study aimed to investigate the association between periprocedural myocardial infarction (PMI), defined by creatine kinase (CK)‐MB or troponin I (TNI) level elevations >5 times the 99th percentile of the upper reference limit (URL) within 48 hr after implantation of a drug‐eluting stent (DES), and one‐year mortality in patients with coronary bifurcation.BackgroundPMI is reported to be associated with increased one‐year mortality after DES implantation. However, the prevalence and association of PMI with mortality after stenting bifurcation lesions remains unclear.MethodsWe prospectively followed 1,971 patients with true coronary bifurcations who underwent DES implantation as part of the multicenter DEFINITION study. These patients were grouped into categories based on PMI outcome: Non‐PMI, CKMB‐PMI, TNI‐PMI, and CKMB/TNI‐PMI. The primary endpoint was the rate of all‐cause mortality at one year.ResultsPMI occurred in 11.4% of patients by CKMB criteria and 41.3% of patients by TNI criteria. At one‐year follow‐up, the mortality rate was 2.3% in the entire patient population. However, mortality was significantly higher in the CKMB‐PMI (6.4%) and CKMB/TNI‐PMI (6.1%) groups compared to the Non‐PMI (1.7%) and TNI‐PMI (2.1%) groups (all P < 0.05). A 10‐fold increase in TNI levels resulted in similar PMI rate (5.2%) and mortality risk (adjusted HR 2.7, 95% CI 3.0–5.2) as a fivefold increase in CKMB levels.ConclusionsPMI, as defined by CKMB elevations following coronary bifurcation lesion stenting, was associated with increased one‐year mortality. Additionally, to attain an equal frequency of PMI, the elevation in TNI levels needed to be twice as high as the elevation in CKMB levels. © 2015 Wiley Periodicals, Inc.

ObjectivesWe sought to describe the morphological characteristics of aortic valve disease in a Chinese population presenting for transcatheter aortic valve replacement (TAVR).BackgroundRacial and regional differences are known to exist in aortic stenosis (AS), but limited data exist comparing the specific anatomical variations between populations.MethodsPatients were prospectively evaluated in a Chinese population presenting for TAVR in the Venus A‐Valve trial, the first trial evaluating TAVR in China. A systematic anatomical assessment protocol employed contrast‐enhanced computed tomography (CT) in all the cases.ResultsA total of 120 consecutive patients were studied. Of these, 61 (50.7%) were patients with tricuspid, 57 (47.5%) bicuspid, and 2 (1.7%) unicuspid valve morphologies. Of the 57 cases with bicuspid valve, 31 (54.4%) had no raphe (Sievers classification, type 0) and 26 (45.6%) were of raphe type. Although the incidence of bicuspid valve morphology was more than a third in the northern Chinese population, this was lower than the eastern Chinese population (P = 0.035), in whom the incidence was more than half. A comparison of tricuspid morphologies in China versus a Western series of 229 consecutive patients undergoing TAVR assessed with CT showed a threefold excess of leaflet calcium burden in China, with a leaflet calcium volume of 421 mm3 (IQR, 188–688 mm3) versus 142 mm3 (IQR, 58–267 mm3).ConclusionsPatients presenting for TAVR in China have a very high frequency of bicuspid valve morphology. Even in tricuspid disease, there are clear differences to Western patients, with a high calcium burden, which presents challenges for TAVR in this population (ClinicalTrials.gov NCT01683474). © 2015 Wiley Periodicals, Inc.
Highly Effective Pt‐Based Water–Gas Shift Catalysts by Surface Modification with Alkali Hydroxide Salts
Authors: Kusche Matthias , Bustillo Karen , Agel Friederike , Wasserscheid Peter 
Published: January 2015

AbstractHerein, we describe an economical and convenient method to improve the performance of Pt/alumina catalysts for the water–gas shift reaction through surface modification of the catalysts with alkali hydroxides according to the solid catalyst with ionic liquid layer approach. The results are in agreement with our findings reported earlier for methanol steam reforming. This report indicates that alkali doping of the catalyst plays an important role in the observed catalyst activation. In addition, the basic and hygroscopic nature of the salt coating contributes to a significant improvement in the performance of the catalyst. During the reaction, a partly liquid film of alkali hydroxide forms on the alumina surface, which increases the availability of H2O at the catalytically active sites. Kinetic studies reveal a negligible effect of the KOH coating on the rate dependence of CO and H2O partial pressures. TEM studies indicate an agglomeration of the active Pt clusters during catalyst preparation; restructuring of Pt nanoparticles occurs under reaction conditions, which leads to a highly active and stable system over 240 h time on stream. Excessive pore fillings with KOH introduce a mass transfer barrier as indicated in a volcano‐shaped curve of activity versus salt loading. The optimum KOH loading was found to be 7.5 wt %.

Published: January 2015

AbstractA hierarchically porous Sr2Fe1.5Mo0.5O6−δ–Gd0.1Ce0.9O1.95 (SFM–GDC) ceramic anode‐supported solid‐oxide fuel cell with a GDC electrolyte film was fabricated by freeze‐drying tape‐casting and drop coating. 3D X‐ray computed tomography analysis indicated that the SFM–GDC anode has a high porosity and low tortuosity factor, facilitating gas diffusion in the anode during fuel cell operation. Peak power density of cells with a La0.6Sr0.4Co0.2Fe0.8O3–GDC (LSCF–GDC) cathode can reach 0.22 W cm−2 at 700 °C when using H2 as the fuel and ambient air as the oxidant. The SFM–GDC anode shows excellent sulfur tolerance when using H2 with 50 ppm H2S. SEM analysis demonstrates that the nanocatalyst (iron) can precipitate from the parent SFM phase upon reduction and iron nanoparticles can react with sulfur species to form needle‐like nanosulfide. Both the nanocatalyst and sulfide show a graded distribution along the thickness direction, owing to a graded local oxygen chemical potential within the anode.
Molybdenum Disulfide/Reduced Graphene Oxide–Carbon Nanotube Hybrids as Efficient Catalytic Materials in Dye‐Sensitized Solar Cells

Published: January 2015

AbstractA hybrid material has been fabricated by combining MoS2/reduced graphene oxide (RGO) nanocomposites with carbon nanotubes (CNTs) (designated MoS2/RGO‐CNTs) through facile electrophoretic deposition. The MoS2/RGO‐CNTs hybrid benefits from the advantages of both MoS2/RGO and CNTs as a counter electrode (CE) in dye‐sensitized solar cells (DSCs). According to a series of electrochemical results, the incorporation of conductive networks of CNTs provides additional pathways for electron transport in the MoS2/RGO‐CNTs hybrid, which increases the charge‐transfer rate at the CE/electrolyte interface. As a result, the MoS2/RGO‐CNTs CE exhibits greatly improved electrocatalytic activity compared with that of MoS2/RGO alone. A DSC incorporating the MoS2/RGO‐CNTs CE achieves impressive cell performance of 7.46 %, which is higher than those measured with DSCs incorporating MoS2/RGO CE (6.82 %) and Pt CE (7.23 %).

AbstractThe photocatalytic activity of phosphonated Re complexes, [Re(2,2′‐bipyridine‐4,4′‐bisphosphonic acid) (CO)3(L)] (ReP; L=3‐picoline or bromide) immobilised on TiO2 nanoparticles is reported. The heterogenised Re catalyst on the semiconductor, ReP–TiO2 hybrid, displays an improvement in CO2 reduction photocatalysis. A high turnover number (TON) of 48 molCO molRe−1 is observed in DMF with the electron donor triethanolamine at λ>420 nm. ReP–TiO2 compares favourably to previously reported homogeneous systems and is the highest TON reported to date for a CO2‐reducing Re photocatalyst under visible light irradiation. Photocatalytic CO2 reduction is even observed with ReP–TiO2 at wavelengths of λ>495 nm. Infrared and X‐ray photoelectron spectroscopies confirm that an intact ReP catalyst is present on the TiO2 surface before and during catalysis. Transient absorption spectroscopy suggests that the high activity upon heterogenisation is due to an increase in the lifetime of the immobilised anionic Re intermediate (t50 %>1 s for ReP–TiO2 compared with t50 %=60 ms for ReP in solution) and immobilisation might also reduce the formation of inactive Re dimers. This study demonstrates that the activity of a homogeneous photocatalyst can be improved through immobilisation on a metal oxide surface by favourably modifying its photochemical kinetics.

AbstractReaction of Co2(CO)8 and 1,3‐propanedithiol in a 1:1 molar ratio in toluene affords a novel tetracobalt complex, [(μ2‐pdt)2(μ3‐S)Co4(CO)6] (pdt=‐SCH2CH2CH2S‐, 1), which possesses some of the structural features of the active site of [FeFe]‐hydrogenase. Carbonyl displacement reaction of complex 1 in the presence of mono‐ or diphosphine ligands leads to the formation of [(μ2‐pdt)2(μ3‐S)Co4(CO)5(PCy3)] (2) and [(μ2‐pdt)2(μ3‐S)Co4(CO)4(L)] [L=Ph2PCHCHPPh2, 3; Ph2PCH2N(Ph)CH2PPh2, 4; Ph2PCH2N(iPr)CH2PPh2, 5]. Complexes 1–5 have been fully characterized by spectroscopy and single‐crystal X‐ray diffraction studies. Cyclic voltammetry has revealed that complexes 1–5 show a reversible first reduction wave and are active for electrocatalytic proton reduction in the presence of CF3COOH. Protonation reactions have been monitored by 31P and 1H NMR and infrared spectroscopies, which revealed the formation of different protonated species. The mono‐reduced species of 1–5 have been spectroscopically characterized by EPR and spectro‐electro‐infrared techniques.

Published: January 2015

AbstractTwo‐dimensional (2D) semiconducting nanosheets have emerged as an important field of materials, owing to their unique properties and potential applications in areas ranging from electronics to catalysis. However, the controlled synthesis of ultrathin 2D nanosheets remains a great challenge, due to the lack of an intrinsic driving force for anisotropic growth. High‐quality ultrathin 2D FeSe2 nanosheets with average thickness below 7 nm have been synthesized on large scale by a facile solution method, and a formation mechanism has been proposed. Due to their favorable structural features, the as‐synthesized ultrathin FeSe2 nanosheets exhibit excellent electrocatalytic activity for the reduction of triiodide to iodide and low charge‐transfer resistance at the electrolyte–electrode interface in dye‐sensitized solar cells (DSSCs). The DSSCs with FeSe2 nanosheets as counter electrode material achieve a high power conversion efficiency of 7.53 % under a simulated solar illumination of 100 mW cm−2 (AM 1.5), which is comparable with that of Pt‐based devices (7.47 %).
Tetraloop‐like Geometries Could Form the Basis of the Catalytic Activity of the Most Ancient Ribooligonucleotides

Published: January 2015

AbstractThe origin of the catalytic activity of ancient oligonucleotides is a largely unexplored field of contemporary science. In the current work we use molecular dynamics simulations to investigate the plausibility of tetraloop‐like overhang geometries to initiate transphosphorylation reactions that lead to ligation and terminal cleavage in simple, Watson–Crick (WC) complementary oligoC/oligoG sequences observed experimentally. We show a series of examples of known tetraloop architectures, which can be adopted by the unpaired overhangs of short oligonucleotide sequences for a sufficiently long time to enable chemical reactions that lead to simple ribozyme‐like catalytic activity. Thus, our computations demonstrate that the role of non‐WC interactions at the emergence of the most ancient catalytic oligonucleotides could be more significant than ever believed.
Ratiometric Fluorescent Nanosensors for Copper(II) Based on Bis(rhodamine)‐Derived PMOs with J‐Type Aggregates

Published: January 2015

AbstractBy using pentyl‐linked bis(rhodamine)‐derived tetra‐siloxane (PRh‐Si4) as the organosilica precursor, highly ordered PRh‐bridged periodic mesoporous organosilicas (PRhPMOs) were prepared. When excited at λ=500 nm, the PRhPMO suspension that contained metal ions showed two separate emission peaks at λ=550 and 623 nm. The first peak, located at λ=550 nm, was due to ring‐opening of the spiro structure in the rhodamine moiety and the second, located at λ=623 nm, originated from fluorescent aggregates of the PRh units embedded in the silica framework of the PRhPMO. By using the different intensity ratios of the two fluorescence signals (FI550/623), PRhPMOs could be used as turn‐ON type fluorescent ratiometric chemosensors for Cu2+. Furthermore, based on the single‐exciton theory, it was deduced that the fluorescent aggregates formed were of the J‐type and had a coplanar configuration. Consequently, PRhPMOs display a longer fluorescence lifetime and greater fluorescent quantum yield than the respective monomers dissolved in solution, which is consistent with the experimental results.
