Cloud vertical structure, precipitation, and cloud radiative effects over Tibetan Plateau and its neighboring regions
Authors: Yan Yafei , Liu Yimin , Lu Jianhua 
Published: May 2016

AbstractThe vertical structure of clouds and its connection with precipitation and cloud radiative effects (CRE) over the Tibetan Plateau (TP) are analyzed and compared with its neighboring land and tropical oceans based on CloudSat and Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) products and the Tropical Rainfall Measuring Mission (TRMM) precipitation data. Unique characteristics of cloud vertical structure and CRE over the TP are found. The cloud amount shows seasonal variation over the TP, which presents a single peak (located in 7–11 km) during January to April and two peaks (located in 5–8 km and 11–17 km separately) after mid‐June, and then resumes to one peak (located in 5–10 km) after mid‐August. Topography‐induced restriction on moisture supply leads to a compression effect on clouds, i.e., the reduction in both cloud thickness and number of cloud layers, over the TP. The topography‐induced compression effect is also shown in the range in the variation of cloud thickness and cloud‐top height corresponding to different precipitation intensity, which is much smaller over the TP than its neighboring regions. The longwave CRE in the atmosphere over the TP is a net cooling effect. The vertical structure of CRE over the TP is unique compared to other regions: there exists a strong cooling layer of net CRE at the altitude of 8 km, from June to the beginning of October; the net radiative heating layer above the surface is shallower but stronger underneath 7 km and with a stronger seasonal variation over the TP.

AbstractKnowledge of sediment dynamics in rivers is of great importance for various practical purposes. Despite its high relevance in riverine environment processes, the monitoring of sediment rates remains a major and challenging task for both suspended and bed load estimation. While the measurement of suspended load is currently an active area of testing with nonintrusive technologies (optical and acoustic), bed load measurement does not mark a similar progress. This paper describes an innovative combination of measurement techniques and analysis protocols that establishes the proof‐of‐concept for a promising technique, labeled herein Acoustic Mapping Velocimetry (AMV). The technique estimates bed load rates in rivers developing bed forms using a nonintrusive measurements approach. The raw information for AMV is collected with acoustic multibeam technology that in turn provides maps of the bathymetry over longitudinal swaths. As long as the acoustic maps can be acquired relatively quickly and the repetition rate for the mapping is commensurate with the movement of the bed forms, successive acoustic maps capture the progression of the bed form movement. Two‐dimensional velocity maps associated with the bed form migration are obtained by implementing algorithms typically used in particle image velocimetry to acoustic maps converted in gray‐level images. Furthermore, use of the obtained acoustic and velocity maps in conjunction with analytical formulations (e.g., Exner equation) enables estimation of multidirectional bed load rates over the whole imaged area. This paper presents a validation study of the AMV technique using a set of laboratory experiments.
Crustal and uppermost mantle structure beneath the United States
Authors: Shen Weisen , Ritzwoller Michael H. 
Published: May 2016

AbstractThis paper presents a new model of the shear velocity structure of the crust and uppermost mantle beneath the contiguous U.S. The model is based on more than a decade of USArray Transportable Array (TA) data across the U.S. and derives from a joint Bayesian Monte Carlo inversion of Rayleigh wave group and phase speeds determined from ambient noise and earthquakes, receiver functions, and Rayleigh wave ellipticity (H/V) measurements. Within the Bayesian inverse theoretic framework, a prior distribution of models is posited and a posterior distribution is inferred beneath all of the more than 1800 TA stations across the U.S. The resulting mean and standard deviation of the mean of the posterior distribution at each station summarize the inversion results, which are then interpolated onto a regular 0.25°×0.25° grid across the U.S. to define the final 3‐D model. We present arguments that show that the standard deviation of the posterior distribution overestimates the effect of nonsystematic errors in the final model by a factor of 4–5 and identify uncertainties in density and mantle Q as primary potential sources of remaining systematic error in the final model. The model presents a great many newly resolved structural features across the U.S. that require further analysis and dedicated explication. We highlight here low‐velocity anomalies in the upper mantle that underlie the Appalachians with centers of anomalies in northern Georgia, western Virginia, and, most prominently, New England.

AbstractNi‐CeO2 is a highly efficient, stable and non‐expensive catalyst for methane dry reforming at relative low temperatures (700 K). The active phase of the catalyst consists of small nanoparticles of nickel dispersed on partially reduced ceria. Experiments of ambient pressure XPS indicate that methane dissociates on Ni/CeO2 at temperatures as low as 300 K, generating CHx and COx species on the surface of the catalyst. Strong metal–support interactions activate Ni for the dissociation of methane. The results of density‐functional calculations show a drop in the effective barrier for methane activation from 0.9 eV on Ni(111) to only 0.15 eV on Ni/CeO2−x(111). At 700 K, under methane dry reforming conditions, no signals for adsorbed CHx or C species are detected in the C 1s XPS region. The reforming of methane proceeds in a clean and efficient way.
Intercalated polyaniline–kaolinite nanocomposite prepared viain situmechanochemical synthesis

Published: May 2016

ABSTRACTThein situpolymerization of aniline monomers within kaolinite interlayers easily led to an intercalated polyaniline (PANI)–kaolinite nanocomposite through a facile mechanochemical method. The X‐ray diffraction results demonstrate that PANI was successfully intercalated in the interlayers of kaolinite, which was lightened by an increased basal spacing from 7.24 to 14.67 Å of kaolinite in the as‐synthesized nanocomposite, and the characterization results from Fourier transform infrared spectrometry, scanning electron microscopy, transmission electron microscopy, and atomic force microscopy further confirm this conclusion. The thermal stability of PANI was improved significantly when PANI was intercalated into kaolinite to form the nanocomposite; this was proven by thermogravimetric analysis. Moreover, a panel experiment was carried out under a simulated marine environment to evaluate the anticorrosive effect of the as‐prepared product, and the results show that the epoxy resin/intercalated PANI–kaolinite nanocomposite coating had a better anticorrosive effect than that of the neat epoxy resin coating. © 2016 Wiley Periodicals, Inc.

Published: May 2016

ABSTRACTRecently, great efforts have been made to gain highly conductive fabrics for smart textiles and flexible electromagnetic shielding materials. Different from the conventional chemical synthesis method, fibrillar polypyrrole was synthesized on the cotton fabrics via a simple chemical polymerization process with micelles of cationic surfactant (cetyltrimethylammonium bromide, CTAB) as soft template. The modified cotton fabric exhibited excellent electrical conductivity and electromagnetic interference shielding effectiveness due to the formation of fibrillar polypyrrole on the fiber surface. Electrical conductivity of fabric surface were studied by four‐probe resistivity system. The highly conductive fabric with surface conductivity of 5.8 S cm−1could be obtained by changing cationic surfactant concentration. The electromagnetic interference shielding effectiveness (EMI SE) of the modified fabrics was evaluated by the vector network analyzer instrument. Compared with the sample without using surfactant, the EMI SE value of PPy‐coated cotton fabrics increased by 28% after using 0.03 M CTAB as soft template. © 2016 Wiley Periodicals, Inc. J. Appl.

Toward a microbial palm oil substitute: oleaginous yeasts cultured on lignocellulose
Authors: Whiffin Fraeya , Santomauro Fabio , Chuck Christopher J. 
Published: May 2016

AbstractPalm oil production is a leading contributor to tropical deforestation, resulting in habitat destruction, increased carbon dioxide emissions, and local smog clouds across South East Asia. Palm oil is widely used for food, as a biofuel precursor, and in soaps and cosmetics. The global demand for palm oil is approximately 57 m tonnes a−1 and is steadily increasing. Alternatively, oleaginous yeast offers a highly credible renewable substitute. Over 80 species of oleaginous yeast are known, many of which have been demonstrated to catabolize a wide range of mono‐ and oligosaccharides in lignocellulose hydrolyzates. Many of the yeasts have demonstrated a high tolerance to furfurals and organic acid inhibitors and can be cultured at low pH, ideal for the industrial production of oil from lignocellulosic sources such as stover, forestry wastes, or energy crops. While the majority of the yeasts produce predominantly monounsaturated esters, some species are capable of producing oils higher in saturates akin to palm oil. While the manufacture of yeast oils on an industrial scale has been demonstrated, currently no large‐scale production from lignocellulose exists; however, through further strain selection, metabolic engineering, and valorization of co‐products, the production of a substitute oil from yeast is potentially feasible. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd

Published: May 2016

AbstractThe blood‐to‐brain transport of amantadine, a weak N‐methyl‐d‐aspartate (NMDA) antagonist, has been shown previously to participate in the cationic drug‐sensitive transport system across the mouse blood–brain barrier (BBB). The purpose of the present study was to characterize the influx transport system by means of both an in situ mouse brain perfusion technique and in vitro studies using rat immortalized brain capillary endothelial cells (GPNT). The observed concentration‐dependent initial uptake rate of [3H]amantadine suggested the involvement of a carrier‐mediated transport mechanism. The normal uptake at physiological pH 7.4 was decreased by 72.9% in acidic perfusate, while it was increased by 35.3% in alkaline perfusate. These results suggest that pH‐dependent transport is regulated by utilizing an oppositely directed proton gradient as a driving force. In addition, the [3H]amantadine uptake was moderately inhibited by the adamantane structural analogs (rimantadine and memantine) and other cationic drugs (pyrilamine, clonidine, nicotine, etc.), but not by substrates or inhibitors of the well‐characterized organic cation transporters (tetraethylammonium, l‐carnitine and choline). A similar inhibition pattern was observed between the in vivo studies and the in vitro experiments. These results indicate that the influx transport for amantadine across the BBB involves a proton‐coupled organic cation antiporter. Copyright © 2016 John Wiley & Sons, Ltd.

AbstractMetabolic glycoengineering (MGE) allows the introduction of unnaturally modified carbohydrates into cellular glycans and their visualization through bioorthogonal ligation. Alkenes, for example, have been used as reporters that can react through inverse‐electron‐demand Diels–Alder cycloaddition with tetrazines. Earlier, norbornenes were shown to be suitable dienophiles; however, they had not previously been applied for MGE. We synthesized two norbornene‐modified mannosamine derivatives that differ in the stereochemistry at the norbornene (exo/endo linkage). Kinetic investigations revealed that the exo derivative reacts more than twice as rapidly as the endo derivative. Through derivatization with 1,2‐diamino‐4,5‐methylenedioxybenzene (DMB) we confirmed that both derivatives are accepted by cells and incorporated after conversion to a sialic acid. In further MGE experiments the incorporated sugars were ligated to a fluorophore and visualized through confocal fluorescence microscopy and flow cytometry.

BackgroundAlcohol septal ablation (ASA) is an alternative treatment for symptomatic hypertrophic obstructive cardiomyopathy (HOCM) patients refractory to pharmacological therapy. We sought to evaluate the immediate and long‐term incidence of death and changes in life quality in a consecutive cohort submitted to ASA.Methods and ResultsBetween October 1998 and December 2013, a total of 56 patients (mean age 53.2 ± 15.5) with symptomatic refractory HOCM were treated with ASA and followed during 15 years (mean 8 ± 4 years). There were 7 (12.5%) deaths, 2 (3.6%) being of cardiac cause. The Kaplan‐Meier survival probability estimate was 96.4% at 1 year, 87.7 at 5 years and 81.0% at 12 years post‐ASA. Significant improvement was observed in life quality assessed by DASI index and NYHA functional class as well as in the left ventricle outflow tract (LVOT) gradient reduction (from 92.8 ± 3.3 mm Hg to 9.37 ± 6.7 mm Hg, P < 0.001) and septum thickness (from 23.9 ± 0.6 mm to 12.9 ± 1.0 mm, P < 0.001). Only one patient (1.7%) required permanent pacemaker immediately after ASA. During follow‐up, one patient had a repeated ASA, three patients underwent myectomy and other four required ICD/pacemaker. In the multivariate model only post‐ASA LVOT residual gradient and left ventricle mass were associated with worse prognosis.ConclusionsIn this long‐term clinical follow‐up without losses, ASA was effective in improving quality of life and NYHA functional class, with relatively low mortality and very low need for immediate permanent pacemaker implantation. © 2016 Wiley Periodicals, Inc.
N‐Heterocyclic Carbenes and Parent Cations: Acidity, Nucleophilicity, Stability, and Hydrogen Bonding—Electrochemical Study and Ab Initio Calculations

Published: May 2016

AbstractN‐Heterocyclic carbenes (NHCs) are widely used as organocatalysts. Their reactivity (and instability) is related to their basicity and nucleophilicity, which, in turn, are linked to their scaffold. NHCs can be generated by chemical deprotonation or electrochemical reduction of the parent azolium cations, NHCH+s. Cyclic voltammetry enabled the reduction potential of the NHCH+s to be determined; the reduction potential is related to the acidity of the NHCH+s and the oxidation potential of the NHCs, which is related to the nucleophilicity of the NHCs. It was thus possible to order different NHCH+s and NHCs by their acidity and nucleophilicity, respectively. A study on the stability of NHCs was also performed in the absence and in the presence of acetic acid to assess the possibility of the coexistence of NHC and an acid in the same solution, opening the possibility of co‐catalysis. Finally, ab initio calculations confirmed the presence, in DMF, of hydrogen‐bonded NHCH+–NHC adducts, which could influence catalyst activity.
