Deformation of basaltic shield volcanoes under cointrusive stress permutations
Authors: Chaput Marie , Famin Vincent , Michon Laurent 
Published: January 2014

AbstractWe performed a microstructural study of Piton des Neiges (La Réunion Island) to understand how intrusions and stresses control each other in basaltic volcanoes. Our study reveals that three perpendicular intrusions trends coexisted during the 2 Myr history of the volcano: a N120–140°E rift zone, a perpendicular dike trend, and swarms of subhorizontal intrusions hereafter called “sill zones”. Independently, the inversion of fault‐slip data shows that incompatible paleostress fields recurrently occurred along with the intrusions: a dominant NNE‐SSW extension, a perpendicular extension, and strike‐slip or compressional regimes. The orientations of paleostresses are consistent with the orientations of the three perpendicular intrusion populations. We propose that stress accumulation in the edifice under the effect of repeated magma injections resulted in permutations of the principal axes of the stress tensor, causing a reorientation of subsequent intrusions. Stress permutations were cyclical. Each cycle started with dike injections in an extensional stress field, reducing the deviatoric stress and switching the axes of principal stresses, and finished with sill intrusions in a compressional stress field. Sill zones acted as detachment planes, restoring the extensional stress field and initiating a new cycle of permutations. Our model of stress permutations is in agreement with the pattern of eruptions and deformation observed at Piton de la Fournaise. In contrast with the Hawaiian model of spreading on a décollement, stress permutations in La Réunion's volcanoes imply that the basal deformation of the edifices, if any, is not sufficient to compensate the reduction of deviatoric stress caused by intrusions.
Prediction and uncertainty of Hurricane Sandy (2012) explored through a real‐time cloud‐permitting ensemble analysis and forecast system assimilating airborne Doppler radar observations
Authors: Munsell Erin B. , Zhang Fuqing 
Published: January 2014

AbstractUtilizing the Pennsylvania State University (PSU) real‐time convection‐permitting hurricane analysis and forecasting system (WRF‐EnKF) that assimilates airborne Doppler radar observations, the sensitivity and uncertainty of forecasts initialized several days prior to landfall of Hurricane Sandy (2012) are assessed. The performance of the track and intensity forecasts of both the deterministic and ensemble forecasts by the PSU WRF‐EnKF system show significant skill and are comparable to or better than forecasts produced by operational dynamical models, even at lead times of 4–5 days prior to landfall. Many of the ensemble members correctly capture the interaction of Sandy with an approaching midlatitude trough, which precedes Sandy's forecasted landfall in the Mid‐Atlantic region of the United States. However, the ensemble reveals considerable forecast uncertainties in the prediction of Sandy. For example, in the ensemble forecast initialized at 0000 UTC 26 October 2012, 10 of the 60 members do not predict a United States landfall. Using ensemble composite and sensitivity analyses, the essential dynamics and initial condition uncertainties that lead to forecast divergence among the members in tracks and precipitation are examined. It is observed that uncertainties in the environmental steering flow are the most impactful factor on the divergence of Sandy's track forecasts, and its subsequent interaction with the approaching midlatitude trough. Though the midlatitude system does not strongly influence the final position of Sandy, differences in the timing and location of its interactions with Sandy lead to considerable differences in rainfall forecasts, especially with respect to heavy precipitation over land.
Growth Actuated Bending and Twisting of Single Crystals
Authors: Shtukenberg Alexander G. , Punin Yurii O. , Gujral Ankit , Kahr Bart 
Published: January 2014

AbstractCrystals of a variety of substances including elements, minerals, simple salts, organic molecular crystals, and high polymers forgo long‐range translational order by twisting and bending as they grow. These deviations have been observed in crystals ranging in size from nanometers to centimeters. How and why so many materials choose dramatic non‐crystallographic distortions is analyzed, with an emphasis on crystal chemistries that give rise to stresses operating either on surfaces of crystallites or within the bulk.
Influence of gelling properties on protein imprinted agarose gel membrane
Authors: Feng Hanbo , Mao Xuan , Chu Bin , Xie Chunlan 
Published: January 2014

ABSTRACTA method based on molecular imprinting technique was presented for preparing protein‐imprinted agarose gel membrane (AGM) under moderate conditions, and the influencing factors such as molecular weights and modified chemical groups on the adsorption ability and selectivity of AGMs were investigated. The agaroses used for AGMs were prepared through ultrasonic degradation, oxidation degradation, gel‐melting method, and sulfation, respectively. Bovine serum albumin (BSA) and hemoglobin were selectively recognized on AGMs. Results showed that the molecular weight was the most crucial influencing factor for the protein recognition ability of AGMs. The lower and upper limit of molecular weight was 100 and 130 kDa, respectively, where the AGMs could maintain both good mechanical strength and high recognition ability, with K value around 4.0. The enhancement of ionic strength could make the imprinting effect disappeared even when the concentration of salt was as low as 2 mmol/L. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

Stepwise Model Evaluation in Simulated Moving‐Bed Separation of Ketamine
Authors: Câmara Leôncio Diógenes T. 
Published: January 2014

AbstractA stepwise model with lumped mass transfer kinetics (SW‐LM) is applied for chromatographic column modeling in simulated moving bed (SMB) separation of a racemic mixture of the anesthetic ketamine. The SW‐LM model can easily represent the SMB separation process of ketamine considering the retention factors equal to the equilibrium constants of the R‐ and S‐enantiomers. The equilibrium data was utilized only in the previous column characterization for the determination of mass transfer kinetic parameters used later in the SMB design. The SW‐LM model achieves similar transient results of enantiomer concentrations in the extract and raffinate compared to a robust equilibrium dispersive model.
Why is Inline NMR Rarely Used as Industrial Sensor? Challenges and Opportunities

Published: January 2014

AbstractAlthough nuclear magnetic resonance (NMR) is one of the most powerful analytical techniques, it has not been widely used as a non‐destructive, non‐contact inline industrial sensor. A short background of NMR spectroscopy fundamentals and instrumentation is presented along with its potential applications and limitations for real‐time analysis in the manufacturing sector. NMR signals are generated in the presence of a magnetic field normally produced by expensive large and heavy magnets which have been the major limiting factor in the use of NMR analysis in factories. However, the last decade has brought substantial advances in the development of cheaper, smaller, and lighter permanent magnets based on rare earth materials that use Halbach and unilateral configurations. Small and light cryogenic‐free superconducting magnets are now offered in the market and are opening a new era in manufacturing. It is expected that soon NMR spectroscopy will be applied to monitor the chemical and physical properties of complex feedstock mixtures and reactions in real time which is the ultimate goal of precise process control.
Encapsulation of a Catalytic Imidazolium Salt into Avidin: Towards the Development of a Biohybrid Catalyst Active in Ionic Liquids
Authors: Gauchot Vincent , Branca Mathieu , Schmitzer Andreea 
Published: January 2014

AbstractHerein, we report the development of biohybrid catalysts that are capable of catalyzing the aldol reaction. The use of biotinylated imidazolium salts in combination with racemic or enantiomerically pure catalytic anions allowed us to study the adaptive and cooperative positioning of the anionic catalyst inside the protein. Supramolecular encapsulation of the biotinylated catalyst into avidin resulted in good selectivity for the aldol reaction performed in ionic liquid/water mixtures.

Published: January 2014

AbstractThe synthesis of three 2D interdigitated ZnII coordination polymers (CPs), by using three monotopic ligands containing CC bonds, is reported. Among these, two CPs with 4spy (4‐styryl pyridine) and 2F‐4spy (a 2′‐fluoro derivative of 4spy) ligands showed quantitative formation of cyclobutane rings, thus demonstrating a unique synthetic procedure to synthesize metal–organic frameworks (MOFs) by using this photochemical reaction. Interestingly, these compounds can also be synthesized by mechanochemical grinding procedures by using Zn(OAc)2. In contrast, Zn(NO3)2 did not yield the required product, unlike in the solution route. In addition, compounds with 4vpy (4‐vinylpyridine), 4spy and 2F‐4spy ligands created different units in the CPs; 4vpy and 2F‐4spy furnished paddle wheel units, whereas 4spy yielded tetrahedral ZnII repeating units. Furthermore, the change in coordination geometry manifests in the photoluminescence properties, attributed to the difference in charge‐transfer and ligand‐centered fluorescent phenomenon.
