Ultrasmall Platinum Nanoparticles on Fe3O4: A Low‐Temperature Catalyst for the Preferential Oxidation Reaction
Authors: Lopez Angela , Larrea Ane , Sebastian Victor , Calatayud M. Pilar , Irusta Silvia , Santamaria Jesus 
Published: March 2016

AbstractPreferential oxidation (PROX) of CO in H2‐rich stream is critical to the production of clean H2 for H2‐based fuel cells. A low‐temperature fuel‐cell start up is desirable for transportation applications. However, few catalysts are able to provide the required sustained activity at near‐room‐temperature conditions. The development of highly active and selective PROX catalysts is highly desirable but has been proven to be extremely challenging. Pt nanoparticles with a size of (1.2±0.1) nm were synthesized in situ on 32 nm magnetite nanoparticles, which were previously deposited on alumina supports. The resulting catalyst was found to be highly active towards the preferential oxidation of CO in a H2‐rich reformate stream and gave 100 % CO conversion at 25 °C with a weight hourly space velocity of 0.5 mL min−1 mg−1 and an oxygen excess factor (λ) of 2.

Published: March 2016

AbstractA study on the influence of the cation coordination number, number of Lewis acid centers, concurrent existence of Lewis base sites, and structure topology on the catalytic activity of six new indium MOFs, has been carried out for multicomponent reactions (MCRs). The new indium polymeric frameworks, namely [In8(OH)6(popha)6(H2O)4]⋅3 H2O (InPF‐16), [In(popha)(2,2′‐bipy)]⋅3 H2O (InPF‐17), [In3(OH)3(popha)2(4,4′‐bipy)]⋅4 H2O (InPF‐18), [In2(popha)2(4,4′‐bipy)2]⋅3 H2O (InPF‐19), [In(OH)(Hpopha)]⋅0.5 (1,7‐phen) (InPF‐20), and [In(popha)(1,10‐phen)]⋅4 H2O (InPF‐21) (InPF=indium polymeric framework, H3popha=5‐(4‐carboxy‐2‐nitrophenoxy)isophthalic acid, phen=phenanthroline, bipy=bipyridine), have been hydrothermally obtained by using both conventional heating (CH) and microwave (MW) procedures. These indium frameworks show efficient Lewis acid behavior for the solvent‐free cyanosilylation of carbonyl compounds, the one pot Passerini 3‐component (P‐3CR) and the Ugi 4‐component (U‐4CR) reactions. In addition, InPF‐17 was found to be a highly reactive, recyclable, and environmentally benign catalyst, which allows the efficient synthesis of α‐aminoacyl amides. The relationship between the Lewis base/acid active site and the catalytic performance is explained by the 2D seven‐coordinated indium framework of the catalyst InPF‐17. This study is an attempt to highlight the main structural and synthetic factors that have to be taken into account when planning a new, effective MOF‐based heterogeneous catalyst for multicomponent reactions.
Controlling the Direction of the Molecular Axis of Rod‐Shaped Binuclear Ruthenium Complexes on Single‐Walled Carbon Nanotubes

Published: March 2016

AbstractWe report the synthesis of a mixed‐valence ruthenium complex, bearing pyrene moieties on one side of the ligands as anchor groups. Composites consisting of mixed‐valence ruthenium complexes and SWNTs were prepared by noncovalent π–π interactions between the SWNT surface and the pyrene anchors of the Ru complex. In these composites, the long axis of the Ru complexes was aligned in parallel to the principal direction of the SWNT. The optimized conformation of these complexes on the SWNT surface was calculated by molecular mechanics. The composites were examined by UV/Vis absorption and FT‐IR spectroscopy, XPS, and SEM analysis. Furthermore, their electrochemical properties were evaluated. Cyclic voltammograms of the composites showed reversible oxidation waves at peak oxidation potentials (Epox) = 0.86 and 1.08 V versus Fc+/Fc, which were assigned to the RuII‐RuII/RuII‐RuIII and the RuII‐RuIII/RuIII‐RuIII oxidation events of the dinuclear ruthenium complex, respectively. Based on these observations, we concluded that the electrochemical properties and mixed‐valence state of the dinuclear ruthenium complexes were preserved upon attachment to the SWNT surface.

Robust prediction of the cumulative incidence function under non‐proportional subdistribution hazards
Authors: Liu Qing , Tang Gong , Costantino Joseph P. , Chang Chung‐Chou H. 
Published: March 2016

AbstractPrediction of a cause‐specific cumulative incidence function (CIF) for data containing competing risks is of primary interest to clinicians when making treatment decisions for patients given their prognostic characteristics. The Fine–Gray regression model is widely used to incorporate multiple prognostic factors, yet it is not applicable when the assumption of proportional subdistribution hazards (PSH) does not hold. In this study we investigate the properties of the partial‐likelihood estimator from the Fine–Gray model under non‐proportionality and propose a robust risk prediction procedure that is not sensitive to the assumption and is more favourable in practice because it bypasses the complicated modelling of time‐varying covariate effects. We evaluate the prediction performance of our procedure in simulations and demonstrate an application in predicting the absolute risk of locoregional recurrence for breast cancer patients, given a set of prognostic factors in which not all of them satisfy the PSH assumption.

Kernel density estimation with Berkson error

AbstractGiven a sample from we construct kernel density estimators for , the convolution of with a known error density . This problem is known as density estimation with Berkson error and has applications in epidemiology and astronomy. Little is understood about bandwidth selection for Berkson density estimation. We compare three approaches to selecting the bandwidth both asymptotically, using large‐sample approximations to the , and at finite samples, using simulations. Our results highlight the relationship between the structure of the error and the optimal bandwidth. In particular the results demonstrate the importance of smoothing when the error term is concentrated near 0. We propose a data‐driven bandwidth estimator and test its performance on NO exposure data. The Canadian Journal of Statistics 44: 142–160; 2016 © 2016 Statistical Society of Canada
Consistent two‐stage multiple change‐point detection in linear models
Authors: Jin Baisuo , Wu Yuehua , Shi Xiaoping 
Published: March 2016

AbstractA two‐stage procedure for simultaneously detecting multiple change‐points in linear models is developed. In the cutting stage, the change‐point problem is converted into a model selection problem so that a modern model selection method can be applied. In the refining stage, the change‐points obtained in the cutting stage are finalized via a refining method. Under mild conditions, consistency of the number of change‐point estimates is established. The new procedure is fast and accurate, as shown in simulation studies. Its applicability in real situations is demonstrated via well‐log and ozone data.The Canadian Journal of Statistics44: 161–179; 2016 © 2016 Statistical Society of Canada
