Detailed validation of an automotive catalysis model using spatially resolved measurements within the catalyst substrate
Authors: Stewart Jonathan , Douglas Roy , Goguet Alexandre , Stere Cristina 
Published: June 2014

Many kinetic models have appeared in literature in past decades using two main approaches: the traditional global kinetics approach, or the more complex micro‐kinetics approach. Whether global or micro‐kinetics, kinetic models have been based on experimental data obtained at the end of the monolith. The experimental procedure using end pipe analysis may give an accurate overview of the reaction mechanisms that occur; however, the lack of information from within the catalyst can ultimately lead to inaccuracies in the kinetic model and parameters used.Using SpaciMS, a spatially resolved experimental technique developed at the Queen's University Belfast, information from within the catalyst can be obtained. This minimally invasive technique provides detailed information of the gas concentration and temperature profile from inside the catalytic monolith. This paper presents a kinetic model and simulations validated against experimental data obtained from three positions inside the catalyst monolith at 2, 14, and 26 mm in, using data from the SpaciMS. Also, simulations of end pipe analysis, using a commercial reactor, for the CO oxidation are presented and analyzed. The simulations presented are for varying concentrations of both CO and O2 (0.5 % and 1 % CO, 0.5 % and 2 % O2) for both the global and micro‐kinetic approach.

Published: June 2014

BACKGROUNDThe effect of care setting on value of colon cancer care is unknown.METHODSA Surveillance, Epidemiology, and End Results (SEER)‐Medicare cohort study of 6544 patients aged ≥66 years with stage IV colon cancer (based on the American Joint Committee on Cancer staging system) who were diagnosed between 1996 and 2005 was performed. All patients were followed through December 31, 2007. Using outpatient and carrier claims, patients were assigned to a treating hospital based on the hospital affiliation of the primary oncologist. Hospitals were classified academic or nonacademic using the SEER‐Medicare National Cancer Institute Hospital File.RESULTSOf the 6544 patients, 1605 (25%) received care from providers affiliated with academic medical centers. The unadjusted median cancer‐specific survival was 16.0 months at academic medical centers versus 13.9 months at nonacademic medical centers (P<.001). After adjustment, treatment at academic hospitals remained significantly associated with a reduced risk of death from cancer (hazard ratio, 0.87; 95% confidence interval [95% CI], 0.82‐0.93 [P<.001]). Adjusted mean 12‐month Medicare spending was $8571 higher at academic medical centers (95% CI, $2340‐$14,802; P = .007). The adjusted median cost was $1559 higher at academic medical centers; this difference was not found to be statistically significant (95% CI, ‐$5239 to $2122; P = .41). A small percentage of patients who received very expensive care skewed the difference in mean cost; the only statistically significant difference in adjusted costs in quantile regressions was at the 99.9th percentile of costs (P<.001).CONCLUSIONSAmong Medicare beneficiaries with stage IV colon cancer, treatment by a provider affiliated with an academic medical center was associated with a 2 month improvement in overall survival. Except for patients in the 99.9th percentile of the cost distribution, costs at academic medical centers were not found to be significantly different from those at nonacademic medical centers.

From Molecules to Materials: Computational Design of N‐Containing Porous Aromatic Frameworks for CO2 Capture
Authors: Li Wenliang , Shi Haijie , Zhang Jingping 
Published: June 2014

AbstractPorous aromatic frameworks (PAFs) are novel materials with diamond topology. With the aim of enhancing their CO2 capture and storage capacity and investigating the effect of nitrogen and/or ‐COOH decorations on CO2 adsorption in PAFs, a series of N‐containing PAFs were designed based on ab initio results. The interaction energies (Eint) between CO2 and each six‐membered ring were calculated at the B2PLYP‐D2/def2‐TZVPP level, then the six‐membered rings with high CO2‐binding affinity were selected and used in the PAFs. To explore the performance of the designed PAFs, the CO2 uptake, selectivity of CO2 over CH4, H2, and N2, and the Eint value of CO2 in PAFs were investigated by using grand canonical Monte Carlo (GCMC) simulations and ab initio calculations. This work shows that pyridine with one nitrogen atom can provide a strong physisorption site for CO2, whereas more nitrogen atoms in heterocycles will reduce the interaction, especially at relatively low pressure. PAFs with COOH groups show high CO2 capacity. Our work provides an efficient way to understand the adsorption mechanism and a supplemental approach to experimental work.
Experimental and Theoretical Investigation of the First‐Order Hyperpolarizability of Octupolar Merocyanine Dyes
Authors: Castet Frédéric , Blanchard‐Desce Mireille , Adamietz Frédéric , Poronik Yevgen M. , Gryko Daniel T. , Rodriguez Vincent 
Published: June 2014

AbstractHyper‐Rayleigh scattering experiments and quantum chemical calculations are combined to investigate the second‐order nonlinear optical responses of a series of three‐arm merocyanine derivatives. They exhibit an octupolar hyperpolarizability response with lower amplitude than crystal violet due to a lower extent of the photoinduced charge transfer and reduced bond length alternation. Strong effects on the second‐order optical response measured close to the two‐photon absorption level are clearly evidenced; for example, the effective measured polarization ratio deviates below the ideal octupolar value of 3/2 even at very low excitation power. These effects are attributed to two‐photon absorption resonance, which we believe modifies dynamically the population of the ground state versus that of the excited state.
Production of Colourful Pigments Consisting of Amorphous Arrays of Silica Particles
Authors: Yoshioka Shinya , Takeoka Yukikazu 
Published: June 2014

AbstractIt is desirable to produce colourful pigments that have anti‐fading properties and are environmentally friendly. In this Concept, we describe recently developed pigments that exhibit such characteristics. The pigments consist of amorphous arrays of submicron silica particles, and they exhibit saturated and angle‐independent structural colours. Variously coloured pigments can be produced by changing the size of the particles, and the saturation of the colour can be controlled by incorporating small amounts of black particles. We review a simple analysis that is useful for interpreting the angular independence of the structural colours and discuss the remaining tasks that must be accomplished for the realistic application of these pigments.
A Density‐Based Adaptive Quantum Mechanical/Molecular Mechanical Method
Authors: Waller Mark P. , Kumbhar Sadhana , Yang Jack 
Published: June 2014

AbstractWe present a density‐based adaptive quantum mechanical/molecular mechanical (DBA‐QM/MM) method, whereby molecules can switch layers from the QM to the MM region and vice versa. The adaptive partitioning of the molecular system ensures that the layer assignment can change during the optimization procedure, that is, on the fly. The switch from a QM molecule to a MM molecule is determined if there is an absence of noncovalent interactions to any atom of the QM core region. The presence/absence of noncovalent interactions is determined by analysis of the reduced density gradient. Therefore, the location of the QM/MM boundary is based on physical arguments, and this neatly removes some empiricism inherent in previous adaptive QM/MM partitioning schemes. The DBA‐QM/MM method is validated by using a water‐in‐water setup and an explicitly solvated L‐alanyl–L‐alanine dipeptide.
Super‐Elastic Air/Water Interfacial Films Self‐Assembled from Soluble Surfactants
Authors: Kovalenko Artem , Polavarapu Prasad , Gallani Jean‐Louis , Pourroy Geneviève , Waton Gilles , Krafft Marie Pierre 
Published: June 2014

AbstractWe show that water‐soluble monosodic salts of F‐alkyl phosphates CnF2n+1(CH2)2OP(O)(OH)2, with n=8 and 10 (F8H2Phos and F10H2Phos) form Gibbs films with exceptionally high dilational viscoelastic modules E that reach ∼900 mN m−1 in the condensed phases. These E values are up to one order of magnitude larger than those recorded for phospholipid, protein and polymer films commonly considered as highly viscoelastic. F8H2Phos.1Na undergoes a transition between a liquid‐expanded and a liquid‐condensed phase. In the case of F10H2Phos.1Na, a transition occurs between a gas phase of surface domains, in which the molecules are densely packed, and a liquid‐condensed phase.

Published: June 2014

A Tm,Ho:CaYAlO4 single crystal was grown using the Czochralski (CZ) method. The absorption spectra, the fluorescence spectrum around 2 μm, the upconversion spectrum and energy‐transfer (ET) schemes between Tm3+ ions and Ho3+ ions have been studied. The crystal boule was free from cracks, inclusions and scattering centers. The broad FWHM of the 797‐nm absorption band (with E//c polarization is 19 nm and with E//a polarization is 18 nm), the large emission bandwidth (about 600 nm) and the intense ET from Tm3+ ions to Ho3+ ions make Tm,Ho:CaYAlO4 a promising media for tunable and ultrashort pulses.
