AbstractThe vertically integrated water budget of West Africa is investigated with a hybrid dataset based on observational and modelling products elaborated by the African Monsoon Multidisciplinary Analyses (AMMA) and with several numerical weather prediction (NWP) products including the European Centre for Medium‐Range Weather Forecasts (ECMWF) AMMA reanalysis. Seasonal and intraseasonal variations are quantified over the period 2002–2007. Links between the budget terms are analyzed regionally, from the Guinean coast to the Sahel zone. Water budgets from the NWP systems are intercompared and evaluated against the hybrid dataset. Large deficiencies are evidenced in all the NWP products. Hypotheses are proposed about their origins and several improvements are foreseen. Copyright © 2010 Royal Meteorological Society
Interactive MATLAB‐based demo program for sum of independent random variables
Authors: Jovanovic Dolecek Gordana 
Published: August 2010

AbstractWe present an interactive MATLAB‐based demo program devoted to teaching undergraduate students the behavior of the sum of independent random variables. The user chooses the type of the variables, and the parameters of these variables. The sum is shown in the time domain followed by the estimation of the probability density of the sum using a histogram. It is subsequently shown that the probability density of the sum of random variables represents the convolution of the density functions of the corresponding variables. The Central Limit Theorem and the progression of the sum towards this limit are illustrated in terms of the number of summands. The software can be used as a complement to theoretical classes or alone as a self‐study tool. Student evaluation of the program is also included. © 2010 Wiley Periodicals, Inc.

Published: August 2010

AbstractRecyclable and efficient heterogeneous catalysts have been prepared by embedding dirhodium(II,II) core carboxylate complexes into the amine‐functionalized nanosized channels of a mesoporous silica host, amine–SBA‐15. Two alternative synthetic procedures for the preparation of the catalysts have been developed and adapted for the immobilization of dirhodium complexes of variable Lewis acidity. The catalytic activity of the resulting solid materials has been evaluated in model cyclopropanation reactions of styrene at variable reaction conditions (reaction substrate, temperature, time, and solvent). Importantly, the designed catalysts, which can be readily recovered and reused, display the reactivity and selectivity profiles exceeding or comparable to their homogeneous dirhodium(II) counterparts.
Synthesis by Replacement Reaction and Application of TiO2‐Supported Au–Ni Bimetallic Catalyst
Authors: Wu Zhijie , Zhao Zongfang , Zhang Minghui 
Published: August 2010

AbstractA TiO2‐supported Au on Ni bimetallic nanoparticle catalyst is prepared by electroless nickel plating and the sequential chemical replacement reaction of supported Ni nanoparticles with Au3+ ions. The size of nickel nanoparticles decreases and highly dispersed gold clusters form on the external surface of the nickel nanoparticles during replacement and sequential thermal treatment. Hydrogen chemisorption and X‐ray photoelectron spectroscopy show the interface interaction between Au atoms and the surface of nickel nanoparticles, optimization of which can enhance hydrogen adsorption and chlorobenzene hydrodechlorination activity and stability. The surface enrichment of gold species on the Au–Ni bimetallic nanoparticles benefits the removal of Cl species from the surface of active sites during hydrodechlorination and then promotes the stability of the catalyst. A series of Au–Ni bimetallic nanoparticles with different particle sizes are synthesized by using different‐sized nickel particles from electroless plating as precursors. The larger Au–Ni nanoparticles exhibit higher hydrodechlorination activity and stability, suggesting that chlorobenzene hydrodechlorination on Au–Ni nanoparticles is structure sensitive. These findings hold promise for a simple route to design and synthesis of bimetallic systems as highly active and stable catalysts for the catalytic reactions.
Application of Response Surface Methodology for Optimization of Xylitol Production from Lignocellulosic Hydrolysate in a Fluidized Bed Reactor
Authors: Sarrouh B. F. , da Silva S. S. 
Published: August 2010

AbstractThis work aims to contribute to the development of a viable technology for the production of xylitol from sugarcane bagasse hemicellulose hydrolysate, using a fluidized bed bioreactor with yeast cells of Candida guilliermondii FTI 20037. To evaluate the technical viability of this biotechnological process, simple batch fermentations were realized according to a 23 factorial design with three center points. Furthermore, the influence of the variables fluidization flux, hydrolysate concentration factor and air flow on process yield and volumetric productivity were evaluated. The results obtained showed that only an increase in fluidization flux had a positive influence on process yield and volumetric productivity. This is due to better oxygen transfer to the inside of the cell, leading to increased xylose consumption and xylitol production rates.
Techno‐Economic Analysis of Hydrazine Hydrate Technologies
Authors: Nikhitha P. , Saibabu K. B. S. 
Published: August 2010

AbstractThe increasing demand of current world production for hydrazine hydrate emphasizes the need to focus on the techno‐economic analysis of the existing technologies. Three processes, namely the Raschig process, urea process, and peroxide‐ketazine process, are chosen for technical analysis followed by cost estimation and economic assessment. The technical part involves the development of flow sheets, process design, carrying out of calculations as well as estimation of raw materials, labor, utilities, and process equipment by sizing and other sub‐components. The economic part comprises the estimation of working capital, fixed capital investment, total capital investment, and total production costs. Economic parameters like net profits, rate of return, payback period, and break‐even point are also estimated to perform economic analysis. The results obtained from technical analysis and economical feasibility studies show that the peroxide‐ketazine‐based hydrazine hydrate technology has clear advantages in terms of raw material consumption and economic competitiveness.
Nanoparticle Production with Stirred‐Media Mills: Opportunities and Limits
Authors: Knieke C. , Steinborn C. , Romeis S. , Peukert W. , Breitung‐Faes S. , Kwade A. 
Published: August 2010

AbstractNanoparticles can be produced by wet grinding in stirred‐media mills. In the lower nanometer range a true grinding limit exists, where the transferred energy from the grinding media is no longer sufficient to induce further breakage of the particles even after stressing events with high stress energies. Variations in process conditions lead to the conclusion that the grinding limit is hardly affected by most of the investigated process parameters. However, at high solids concentrations and/or small particle sizes, a drastic increase in suspension viscosity occurs, which leads to a dampening of the grinding media motion and to a reduction in the transferred stress energy. Hence, the rheological behavior can limit the grinding process, and a viscous dampening‐related grinding limit can be reached prior to the true grinding limit.
Two Colliding Grinding Beads: Experimental Flow Fields and Particle Capture Efficiency

Published: August 2010

AbstractHydrodynamics plays a major role in wet grinding processes used to produce nanoparticles, but its influence on the mechanisms of fragmentation is not fully understood. The focus is on hydrodynamics in the gap between two grinding beads. Using particle image velocimetry in a large‐scale experiment, the velocity field between the beads has been investigated when the beads get closer (down to one‐tenth of their radius). Different configurations have been studied, varying from frontal approach to tangential collision. Finally, a capture probability of suspended particles has been estimated.
Site‐Specific Investigation of the Steady‐State Kinetics and Dynamics of the Multistep Binding of Bile Acid Molecules to a Lipid Carrier Protein

Published: August 2010

AbstractThe investigation of multi‐site ligand–protein binding and multi‐step mechanisms is highly demanding. In this work, advanced NMR methodologies such as 2D 1H–15N line‐shape analysis, which allows a reliable investigation of ligand binding occurring on micro‐ to millisecond timescales, have been extended to model a two‐step binding mechanism. The molecular recognition and complex uptake mechanism of two bile salt molecules by lipid carriers is an interesting example that shows that protein dynamics has the potential to modulate the macromolecule–ligand encounter. Kinetic analysis supports a conformational selection model as the initial recognition process in which the dynamics observed in the apo form is essential for ligand uptake, leading to conformations with improved access to the binding cavity. Subsequent multi‐step events could be modelled, for several residues, with a two‐step binding mechanism. The protein in the ligand‐bound state still exhibits a conformational rearrangement that occurs on a very slow timescale, as observed for other proteins of the family. A global mechanism suggesting how bile acids access the macromolecular cavity is thus proposed.
General Strategy for a Large‐Scale Fabric with Branched Nanofiber–Nanorod Hierarchical Heterostructure: Controllable Synthesis and Applications

Published: August 2010

AbstractThe preparation and characterization of a branched nanofiber–nanorod hierarchical heterostructure fabric (TiO2/NiO, TiO2/ZnO, and TiO2/SnO2) are described. The nanomaterial was synthesized on a large scale by an inexpensive, generalizable, facile, and controllable approach by combining the electrospinning technique with a hydrothermal method. The controllable formation process and factors (assistance by hexamethylenetetramine and metal oxide nuclei) influencing the morphology of the branched hierarchical heterostructure are discussed. In addition, photocurrent and photocatalytic studies suggest that the branched hierarchical heterostructure fabric shows higher mobility of charge carriers and enhanced photocatalytic activity relative to a bare TiO2 nanofibrous mat and other heterostructures under irradiation by light. This work demonstrates the possibility of growing branched heterostructure fabrics of various uniform, one‐dimensional, functional metal oxide nanorods on a TiO2 nanofibrous mat, which has a tunable morphology by changing the precursor. The study may open a new channel for building hierarchical heterostructure device fabrics with optical and catalytic properties, and allow the realization of a new class of nano‐heterostructure devices.
Enhanced Anion Binding from Unusual Coordination Modes of Bis(thiourea) Ligands in Platinum Group Metal Complexes

Published: August 2010

AbstractTreatment of a range of bis(thiourea) ligands with inert organometallic transition‐metal ions gives a number of novel complexes that exhibit unusual ligand binding modes and significantly enhanced anion binding ability. The ruthenium(II) complex [Ru(η6‐p‐cymene)(κS,S′,N‐L3−H)]+ (2 b) possesses juxtaposed four‐ and seven‐membered chelate rings and binds anions as both 1:1 and 2:1 host guest complexes. The pyridyl bis(thiourea) complex [Ru(η6‐p‐cymeme)(κS,S′,Npy‐L4)]2+ (4) binds anions in both 1:1 and 1:2 species, whereas the free ligand is ineffective because of intramolecular NH⋅⋅⋅N hydrogen bonding. Novel palladium(II) complexes with nine‐ and ten‐membered chelate rings are also reported.
