Structural Diversity of Calcium Organocuprates(I): Synthesis of Mesityl Cuprates via Addition and Transmetalation Reactions of Mesityl Copper(I)
Authors: Krieck Sven , Görls Helmar , Westerhausen Matthias
Published: January 2010

The addition of [(L)4Ca(I)Mes] (Lewis base L=thf, Et2O) to mesityl copper(I) and the transmetalation reaction of mesityl copper(I) with activated calcium are suitable pathways for the synthesis of dimesityl cuprates(I) of calcium. However, the structures of the calcium cuprates(I) depend on the preparative procedure. The transmetalation reaction leads to the formation of [Mes‐Cu‐Mes]− anions whereas the addition yields dinuclear [(Mes‐Cu)2(μ‐Mes)]− anions. The solvent‐separated counterions are [Ca(thf)6]2+ and [(thf)5CaI]+, respectively. In contrast to these findings, the addition of [(L)4Ca(I)Mes] to mesityl copper(I) in an Et2O/toluene mixture led to formation of tetrameric solvent‐free iodocalcium dimesityl cuprate(I) [ICa(μ‐η1,η6‐Mes2Cu)]4, representing a rare example of a heavy Normant‐type organocuprate.
On the correlation of “static” and “dynamic” stiffness moduli of non‐cohesive soils
Authors: Wichtmann Torsten , Triantafyllidis Theodor
Published: January 2010

The secant stiffness of the stress – strain – hysteresis during a cyclic or dynamic loading with very small strain amplitudes is sometimes called “dynamic” stiffness of a soil. In contrast, a “static” stiffness is obtained from the first loading curve in oedometric or triaxial tests. Indeed, the difference between “dynamic” (small‐strain) and “static” (large‐strain) stiffness moduli is due to the different magnitude of strain or strain amplitude and not due to different loading rates. The small strain stiffness is an important design parameter for foundations subjected to a cyclic or dynamic loading. However, its determination in situ or from laboratory tests is laborious and expensive. In practice, the small‐strain stiffness is often estimated by means of a diagram correlating “dynamic” and “static” stiffness moduli. However, the assumptions and the range of applicability of this correlation are not clear. The present paper presents an inspection of this correlation for four sands with different grain size distribution curves. The “static” stiffness was obtained from tests with monotonic oedometric or triaxial compression. The “dynamic” stiffness was determined in resonant column tests and from measurements of the P‐wave velocity. For some of the tested sands, significant deviations of the experimental data from the correlation actually used in practice were obtained. Modified correlations are proposed in the paper.
Calculation of deformations of an underwater excavation using parameters of Berlin sand from a hypoplastic model
Authors: Herle Ivo , Mayer Peter‐Michael
Published: January 2010

Soil parameters are always related to particular constitutive laws. For the application of elastic‐perfectly plastic constitutive models in commercial FE codes, it is necessary to determine a large number of parameters because soil stiffness and friction angle are pressure‐ and density‐dependent. On the contrary, the hypoplastic model includes only pressure‐ and density‐independent constants which are closely related to the properties of grain assemblies. The determination of hypoplastic parameters is demonstrated for Berlin sand, and it is shown how conventional stiffness and strength quantities can be calculated using hypoplasticity. Afterwards, a FE calculation of an anchored wall in Berlin is performed with the Mohr‐Coulomb constitutive law and soil parameters from the hypoplastic model. Results of the calculation coincide well with the measured values. Nevertheless, limitations of such a procedure are pointed out and the need for more comprehensive constitutive laws in complex boundary value problems is emphasized.
Sichtbeton aus Spritzbeton
Authors: Hankers Christoph
Published: January 2010

Die Verwendung von Spritzbeton für die Instandsetzung und Verstärkung von Bauwerken, für den Tunnelbau und zur Sicherung von Baugruben und Stützwänden ist Stand der Technik und wird millionenfach angewandt. Auch der Bau von Schalentragwerken ist eine Spritzbetondomaine. Weniger bekannt ist die Tatsache, dass mit Spritzbeton auch optisch ansprechende Flächen und Strukturen geschaffen werden können. Vereinzelt wird Spritzbeton bewusst zur Gestaltung von Fassaden eingesetzt. Neu ist die Methode, profilierten Spritzbeton bewusst als Sichtbeton zu verwenden. In Kombination mit einer temporären, in die Oberfläche eingelegten Matrize ergeben sich interessante gestalterische Perspektiven und Möglichkeiten. Sie werden anhand von Ausführungsbeispielen erläutert.

Authors: Gödde Lars , Strack Mathias , Mark Peter
Published: January 2010

Mit der zu erwartenden Einführung der Richtlinie “Stahlfaserbeton” des Deutschen Ausschuss für Stahlbeton (DAfStb) entsteht für den Verbundwerkstoff Stahlfaserbeton ein neues, breites Spektrum an zusätzlichen Anwendungsmöglichkeiten. Durch die Wirkung der Fasern im Beton können nach Überschreitung der Betonzugfestigkeit nennenswerte Kräfte zwischen den Rissufern übertragen und bei der rechnerischen Erfassung des Tragverhaltens berücksichtigt werden. Im Aufsatz werden Vorgehensweisen, Hilfsmittel und ein auf Tabellenkalkulationen und Optimierungsmethoden basierendes Programm zur Biegebemessung und Verformungsabschätzung von Querschnitten und Systemen aus Stahlfaserbeton und stahlfaserverstärktem Stahlbeton entwickelt. Grundlage sind die bekannten Bemessungsansätze und ‐hilfsmittel für Stahlbetonquerschnitte. Die Anwendung der Hilfsmittel – auch für Verformungsabschätzungen auf Basis nichtlinearer Verfahren – zeigen zwei Beispiele.

Structural Elements of Steel Fibre Reinforced Concrete with or without Bar Reinforcement Tools for Design and Deflection Estimations according to the Guideline “Stahlfaserbeton” by DAfStb

The expected release of the guideline “Stahlfaserbeton” by ‘German Committee for Reinforced Concrete’ (DAfStb) offers a wide application range for the composite material steel fibre reinforced concrete (SFRC). Due to additional steel fibres in concrete considerable tension forces can be transferred between crack edges after reaching plain concrete's tensile strength. These forces can be accounted for in calculation of load bearing capacity. Adapted from common design methods and tools for plain reinforced concrete new procedures, tools and a computer application – based on spreadsheet analysis and optimisation methods – for SFRC are presented in this article. These allow for both bending design as well as deflection estimation of crosssections and structural systems made of SFRC with and without additional rebars. Their application – also in case of deflection estimation using non‐linear methods – is demonstrated in two elaborated examples.
Expression, purification, and analysis of unknown translation factors from Escherichia coli: A synthesis approach
Authors: Walter Justin D. , Littlefield Peter , Delbecq Scott , Prody Gerry , Spiegel P. Clint
Published: January 2010

New approaches are currently being developed to expose biochemistry and molecular biology undergraduates to a more interactive learning environment. Here, we propose a unique project‐based laboratory module, which incorporates exposure to biophysical chemistry approaches to address problems in protein chemistry. Each of the experiments described herein contributes to the stepwise process of isolating, identifying, and analyzing a protein involved in a central biological process, prokaryotic translation. Students are provided with expression plasmids that harbor an unknown translation factor, and it is their charge to complete a series of experiments that will allow them to develop hypotheses for discovering the identity of their unknown (from a list of potential candidates). Subsequent to the identification of their unknown translation factor, a series of protein unfolding exercises are performed employing circular dichroism and fluorescence spectroscopies, allowing students to directly calculate thermodynamic parameters centered around determining the equilibrium constant for unfolding as a function of denaturant (temperature or chemical). The conclusion of this multi‐part laboratory exercise consists of both oral and written presentations, emphasizing synthesis of the roles of each translation factor during the stepwise process of translation.
Bridging the educational research‐teaching practice gap
Authors: Anderson Trevor R. , Rogan John M.
Published: January 2010

Student assessment is central to the educational process and can be used for multiple purposes including, to promote student learning, to grade student performance and to evaluate the educational quality of qualifications. It is, therefore, of utmost importance that assessment instruments are of a high quality. In this article, we present various tools that instructors could use, both to improve instrument design and validity before presentation to students and, to evaluate the reliability and quality of the assessment after students have answered the questions. In keeping with our goals of the Bridging‐the‐Gap series, we also present various ideas from the educational literature regarding the evaluation of assessment quality and end with a list of criteria that instructors could use to guide their evaluation process.
Incorporating a collaborative web‐based virtual laboratory in an undergraduate bioinformatics course
Authors: Weisman David
Published: January 2010

Face‐to‐face bioinformatics courses commonly include a weekly, in‐person computer lab to facilitate active learning, reinforce conceptual material, and teach practical skills. Similarly, fully‐online bioinformatics courses employ hands‐on exercises to achieve these outcomes, although students typically perform this work offsite. Combining a face‐to‐face lecture course with a web‐based virtual laboratory presents new opportunities for collaborative learning of the conceptual material, and for fostering peer support of technical bioinformatics questions. To explore this combination, an in‐person lecture‐only undergraduate bioinformatics course was augmented with a remote web‐based laboratory, and tested with a large class. This study hypothesized that the collaborative virtual lab would foster active learning and peer support, and tested this hypothesis by conducting a student survey near the end of the semester. Respondents broadly reported strong benefits from the online laboratory, and strong benefits from peer‐provided technical support. In comparison with traditional in‐person teaching labs, students preferred the virtual lab by a factor of two. Key aspects of the course architecture and design are described to encourage further experimentation in teaching collaborative online bioinformatics laboratories.
Accessing the vocal folds by transcutaneous injection
Authors: Pearson William , Hutchinson Christoph T. , Noordzij J. Pieter
Published: January 2010

This study tested three techniques and two approaches to access the vocal fold (VF) by transcutaneous injection using a cadaver model. The three techniques include an anatomically informed geometric technique, flexible laryngoscope (FL) guidance, and planned injection with use of computed tomography (CT). The two approaches for injection include the thyrohyoid membrane (THM) and the cricothyroid membrane (CTM). The hypothesis was that the VF is more reliably reached with techniques using technological visualization and the THM and CTM provides equal access to the VF. A geometric approach to the VF was developed and tested on seven formalin‐fixed human cadavers with three injections of 0.5 ml pigmented acrylic polymer through the CTM and one through the THM. The FL‐guided technique through the THM and the CTM was tested on eight formalin‐fixed human cadavers and the CT informed technique on two subjects. All tests were inspected by dissection and results recorded. Pertinent measurements and characteristics of each technique were recorded. Data were analyzed for statistical significance for each approach and technique. A chi‐square analysis revealed that a technology guided technique was more successful than anatomical knowledge alone (X2 = 6.55, P = 0.01). The null hypothesis that the VF was equally accessed through the THM and the CTM was rejected (X2 = 5.33, P = 0.02). We found that technology guided visualization is better than anatomical knowledge alone in accessing the VF. We also found that the CTM approach provides more reliable access to the entire length of the VF. Clin. Anat. 23:270–276, 2010. © 2010 Wiley‐Liss, Inc.

Enzymatic Thioxyloside Synthesis: Characterization of Thioglycoligase Variants Identified from A Site‐Saturation Mutagenesis Library of Bacillus Circulans Xylanase
Authors: Armstrong Zachary , Reitinger Stephan , Kantner Terrence , Withers Stephen G.
Published: January 2010

Thioglycoligases are engineered enzymes for the synthesis of thioglycosides that are derived from retaining glycosidases by replacing the acid/base catalyst. The optimal choice of substitution for the acid/base mutant is currently unknown, so to investigate this question a complete acid/base library of the model glycosidase Bacillus circulans xylanase (Bcx) was generated by using site‐saturation mutagenesis. A novel screening approach combining active site titration with semiquantitative product analysis by thin layer chromatography was established and used to evaluate specific activities of each mutant enzyme within crude cell lysates. The six most active Bcx variants were analyzed in more detail, a pH optimum of 8.5 was established and the identity of reaction products was confirmed. Optimal choices for substitution were small, preferably polar amino acids such as threonine, cysteine, and serine. We discuss the resultant data in the context of previously published studies on thioglycoligases.
Mechanism of CO Disproportionation on Reduced Ceria
Authors: Liu Yi , Wen Cun , Guo Yun , Liu Xiaohui , Ren Jiawen , Lu Guanzhong , Wang Yanqin
Published: January 2010

CO disproportionation produces carbon deposits that cover active sites and induce catalyst deactivation. However, understanding of this detrimental reaction on reduced ceria is deficient. Herein, the reversibility and reaction mechanism of CO disproportionation on reduced ceria are investigated. The reversibility of the CO disproportionation was studied by CO pulse, isotopic oxygen tracer, thermal analysis, and CO2 pulse experiments. In situ diffuse‐reflectance infrared Fourier transform spectra indicate that the CO bond of the CO molecule on Ce3+ ion is weakened. With CO bond dissociation, asymmetrical inorganic carboxylate species are formed. These species are the key reaction intermediates in CO disproportionation and are further converted to produce CO2. EPR experiments indicate that the unpaired electrons produced by the reduction weaken the CO bond through back‐donation of electrons.
Simultaneous Elimination of Pyrophoricity and Enhancement of Activity of Raney Nickel by Carbon Deposition: Synthesis of Highly Active NiC Catalysts
Authors: Mahata Nagendranath , Cunha Adelino F. , Órfão José J. M. , Figueiredo José L.
Published: January 2010

Nickel‐carbon composite materials (NiC catalysts) are synthesized by decomposing methane over Raney‐type skeletal nickel catalysts. The NiC catalysts are evaluated in the hydrogenation of cyclooctene, cyclooctadiene, nitrobenzene, and para‐chloronitrobenzene. Characterization by scanning electron microscopy, X‐ray diffraction, and X‐ray photoelectron spectroscopy reveals that the catalysts consist of nickel in its metallic form with superficial oxide layers, carbon, and aluminum oxide/hydroxide. The catalysts exhibited excellent hydrogenation activity, superior to the parent Raney nickel.
Effect of Ultrasound on SO2 Desorption from Sodium Alkali Desulphurization Regeneration Solution
Authors: Xu H. , Zhang S.‐T. , Lu X.‐B. , Liu Y. , Yu X.‐Y.
Published: January 2010

The influence of an ultrasonic field on SO2 desorption from sodium alkali desulfurization regeneration solution was studied in this work. The SO2 desorption experiments were carried out in the presence and absence of ultrasound at 25 kHz. The results showed that the use of ultrasound could enhance the SO2 desorption rate from the sodium alkali desulfurization regeneration solution. By analyzing the composition of regeneration solutions with different pH values, two steps for the desorption process were proposed, both with and without ultrasound conditions, i.e., the first step was the decomposition of sulfurous acid (H2SO3), and the second step was the decomposition of sodium bisulfite (NaHSO3). Furthermore, the use of ultrasound was seen to promote the first step, while it was not seen to have a significant effect on the second step. It was also found that the decomposition of H2SO3 in the first step could be considered as a gas mass transfer process from the liquid phase to the gaseous phase and the overall volumetric mass transfer coefficient, KL·a, increased on using ultrasound compared to the value in the absence of an ultrasonic field.

Published: January 2010

The cyclic oxidation behavior of an experimental stainless ferritic steel, without molybdenum and with copper‐aluminum‐titanium‐lanthanum additions, developed for solid oxide fuel cell applications, was evaluated and compared with the oxidation behavior of commercial austenitic and ferritic stainless steels. For the cyclic oxidation tests, the steel samples were tested at temperatures ranging from 600 to 800 °C. The experimental ferritic stainless steel showed the highest cyclic oxidation behavior among the studied steels at 700 °C and 800 °C, presenting a parabolic and logarithmic kinetics, respectively.
Heat and Mass Transfer between Air and Liquid Desiccant in Cross‐flow Contact Systems
Authors: Babakhani D. , Soleymani M. , Moheb A.
Published: January 2010

In this paper, an analytical solution of the coupled heat and mass transfer process in a cross‐flow liquid‐desiccant dehumidifier/regenerator is developed. By the use of reliable assumptions, the government equations for the system are solved by an analytical method. The results of the present analytical solution are compared with experimental data from the literature, and they show good agreement. The maximum error produced by the presented analytical solution is less than 12 %. The effect of the operating parameters is considered using the presented analytical solution. The results show that air inlet humidity, air flow rate, desiccant inlet temperature, and desiccant inlet concentration have more influence on the moisture removal rate in the cross‐flow dehumidifier. Also, air inlet humidity, desiccant inlet temperature, desiccant inlet concentration and desiccant flow rate have more effect on the moisture removal rate in the cross‐flow regenerator. The effect of the Lewis number on the performance of the dehumidifier/regenerator is investigated. As the results show, by the use of Le = 1.08 in the dehumidification process and Le = 0.96 in the regeneration process, instead of the value of unity, better results are obtained. The benefit of the present study is a simplified application for the evaluation of the outlet parameters of the cross‐flow air dehumidifier/regenerator.
Roles of Pumps and Bypass in Chemistry Induced by Hydrodynamic Cavitation
Authors: Braeutigam P. , Wu Z.‐L. , Stark A. , Ondruschka B.
Published: January 2010

In this investigation, a self‐made low pressure device (up to 100 psi) for creating hydrodynamic cavitation was optimized by using the Weissler reaction. Optimal upstream pressure for the reaction was obtained for a single line system (without bypass) as 29 psi. The effects of the centrifugal pump and the bypass were significant as compared with the effect of the restrictions investigated. Therefore, the use of more lines is proposed. The effects of different restrictions (valve, one‐hole plate, and multi‐hole plate) were investigated and multi‐hole plates show better efficiency.
Influence of a Lipid Phase on the Physical Properties of Spray‐Dried Maltodextrin Powders
Authors: Martins P. C. , Kieckbusch T. G.
Published: January 2010

Maltodextrin powders containing 5, 10, 15, 20 and 25 % from three different palm oil fractions were produced by spray‐drying emulsions with 30 wt % total solids content. The effect of the lipid phase on the characteristics of the particles was evaluated. Oilless spray‐dried particles presented a smaller average size and reduced wettability as compared to the commercial product. An increase in fat content resulted in a decrease in true density while the Hausner Ratio and average diameter of the particles increased. The powders containing palm olefins (melting points, 14 °C and 18 °C) were stickier than the product containing stearin (melting point, 51 °C).
A Combined Theoretical and Experimental Investigation on the Enantioselective Oxidation of Aryl Benzyl Sulfides in the Presence of a Chiral Titanium Catalyst
Authors: Naso Francesco , Capozzi Maria Annunziata M. , Bottoni Andrea , Calvaresi Matteo , Bertolasi Valerio , Capitelli Francesco , Cardellicchio Cosimo
Published: January 2010

An experimental investigation of the enantioselective oxidation of aryl benzyl sulfides by tert‐butyl hydroperoxide in the presence of a titanium/hydrobenzoin catalyst has shown that these sulfides are ideal substrates for this catalytic system, with negligible interference by the substituents on the aryl groups. A reaction mechanism based on DFT computations has been proposed. The DFT MPWB1K functional was used in the theoretical investigation to account for weak hydrogen‐bonding and π interactions. The computed reaction profile explains the experimentally observed enantioselectivity, which is determined by the thermodynamics of the first phase of the reaction. A detailed discussion of the hydrogen‐bonding and π interactions that drive the reaction along the observed stereochemical path is given.
Chiral and Nonchiral [OsX2(diphosphane)(diamine)] (X: Cl, OCH2CF3) Complexes for Fast Hydrogenation of Carbonyl Compounds
Authors: Baratta Walter , Barbato Cinzia , Magnolia Santo , Siega Katia , Rigo Pierluigi
Published: January 2010

The osmium complexes trans‐[OsCl2(dppf)(diamine)] (dppf: 1,1′‐bis(diphenylphosphino)ferrocene; diamine: ethylenediamine in 3, propylenediamine in 4) were prepared by the reaction of [OsCl2(PPh3)3] (1) with the ferrocenyl diphosphane, dppf and the corresponding diamine in dichloromethane. The reaction of derivative 3 with NaOCH2CF3 in toluene afforded the alkoxide cis‐[Os(OCH2CF3)2(dppf)(ethylenediamine)] (5). The novel precursor [Os2Cl4(P(m‐tolyl)3)5] (2) allows the synthesis of the chiral complexes trans‐[OsCl2(diphosphane)(1,2‐diamine)] (6–9; diphosphane: (R)‐[6,6′‐dimethoxy(1,1′‐biphenyl)‐2,2′‐diyl]bis[1,1‐bis(3,5‐dimethylphenyl)phosphane] (xylMeObiphep) or (R)‐(1,1′‐binaphthalene)‐2,2′‐diylbis[1,1‐bis(3,5‐dimethylphenyl)phosphane] (xylbinap); diamine=(R,R)‐1,2‐diphenylethylenediamine (dpen) or (R,R)‐1,2‐diaminocyclohexane (dach)), obtained by the treatment of 2 with the diphosphane and the 1,2‐diamine in toluene at reflux temperature. Compounds 3–5 in ethanol and in the presence of NaOEt catalyze the reduction of methyl aryl, dialkyl, and diaryl ketones and aldehydes with H2 at low pressure (5 atm), with substrate/catalyst (S/C) ratios of 10 000–200 000 and achieving turnover frequencies (TOFs) of up to 3.0×105 h−1 at 70 °C. By employment of the chiral compounds 6–9, different ketones, including alkyl aryl, bulky tert‐butyl, and cyclic ketones, have successfully been hydrogenated with enantioselectivities up to 99 % and with S/C ratios of 5000–100 000 and TOFs of up to 4.1×104 h−1 at 60 °C.

Published: January 2010

The present study reports the evidence for the multiple carbon–carbon bond insertion into the metal–heteroatom bond via a five‐coordinate metal complex. Detailed analysis of the model catalytic reaction of the carbon–sulfur (CS) bond formation unveiled the mechanism of metal‐mediated alkyne insertion: a new pathway of CS bond formation without preliminary ligand dissociation was revealed based on experimental and theoretical investigations. According to this pathway alkyne insertion into the metal–sulfur bond led to the formation of intermediate metal complex capable of direct CS reductive elimination. In contrast, an intermediate metal complex formed through alkyne insertion through the traditional pathway involving preliminary ligand dissociation suffered from “improper” geometry configuration, which may block the whole catalytic cycle. A new catalytic system was developed to solve the problem of stereoselective SS bond addition to internal alkynes and a cost‐efficient Ni‐catalyzed synthetic procedure is reported to furnish formation of target vinyl sulfides with high yields (up to 99 %) and excellent Z/E selectivity (>99:1).

An efficient tandem reaction for the asymmetric synthesis of six‐membered spirocyclic oxindoles has been successfully developed through a formal [2+2+2] annulation strategy. The amine‐catalysed stereoselective Michael addition of aliphatic aldehydes to electron‐deficient olefinic oxindole motifs gave chiral C3 components, which were further combined with diverse electrophiles (activated olefins or imines) to afford spirocyclic oxindoles with versatile molecular complexity (up to six contiguous stereogenic centres, high diastereo‐ and enantioselectivities).
