Hochduktiler Beton mit Kurzfaserbewehrung
Authors: Mechtcherine Viktor 
Published: January 2015

AbstractHochduktile Betone mit Kurzfaserbewehrung (meist Polyvinilalkohol‐ oder hochmodulige Polyethylenmikrofaser) sind neue zementgebundene Hochleistungswerkstoffe, die unter Zugbeanspruchung eine Verfestigung aufweisen und eine im Vergleich zu gebräuchlichen Faserbetonen mehr als einhundertmal höhere Bruchdehnung besitzen. Neben ihrer großen Verformungsfähigkeit sowie hohen Biegezug‐ und Schubfestigkeit weisen hochduktile Betone bis zur Bruchdehnung sehr geringe Rissöffnungen auf. Diese besonderen Eigenschaften machen diese neue Betonart für spezielle Anwendungen sowohl bei Neubau als auch bei Verstärkung und Instandsetzung von bestehenden Bauwerken interessant. Dieser Aufsatz gibt einen Überblick über die baustofflichen Grundlagen, die Eigenschaften und Anwendungsmöglichkeiten der neuen Faserbetonart.Strain‐hardening cement‐based compositesMaterial design, properties and applications in constructionStrain‐hardening cement‐based composites (SHCC) are new, high‐performance materials reinforced in most cases with either polyvinyl‐alcohol or high‐density polyethylene fibre. These composites exhibit strain‐hardening behaviour under tensile loading. They have a strain capacity on an order of magnitude of more than one hundred times that of ordinary fibre‐reinforced concrete. SHCC have relatively high tensile and shear strengths and up until reaching strain capacity yield only very narrow, multiple cracks. These specific features make this new type of concrete attractive for a number of practical applications both in new construction and in the repair and strengthening of existing structures. The article at hand provides an overview of SHCCs' material design as well as of their mechanical performance, durability and fields of application.
Untersuchungen zur Alkali‐Kieselsäure‐Reaktion in vorgeschädigten Fahrbahndeckenbetonen
Authors: Giebson Colin , Voland Katja , Ludwig Horst‐Michael , Meng Birgit 
Published: January 2015

AbstractIn Betonbauteilen unter gleichzeitiger zyklischer Beanspruchung und externer Alkalizufuhr ist die Gefahr von Schäden infolge oder unter Mitwirkung einer Alkali‐Kieselsäure‐Reaktion (AKR) besonders hoch. Dies betrifft insbesondere Fahrbahndecken, bedingt durch den zunehmenden Schwerlastverkehr und den winterlichen Auftrag des Enteisungsmittels NaCl. Speziell die Rolle einer mechanischen Vorschädigung des Betons infolge der Verkehrsbeanspruchungen auf den Ablauf einer AKR ist dabei aber noch nicht in ausreichendem Umfang geklärt. Ein Teil der dazu seit 2012 durchgeführten Untersuchungen im Rahmen der DFG‐Forschergruppe 1498 soll im Folgenden vorgestellt werden. Es zeigte sich, dass eine AKR in definiert mechanisch vorgeschädigten Betonprobekörpern mit alkalireaktiven Gesteinskörnungen und unter äußerer Alkalizufuhr vor allem früher beginnt als in äquivalenten Probekörpern ohne Vorschädigung. Grund dafür ist das schnellere und tiefere Eindringen von Wasser und insbesondere gelöstem NaCl in den Beton, wodurch Na‐Ionen als Reaktionspartner für eine AKR früher und langfristig auch in größerer Menge verfügbar sind.Investigations into alkali‐silica reaction in pre‐damaged pavement concretesIn concrete elements, simultaneously subjected to cyclic loadings and external alkalis, the risk for damages caused by or under participation of an alkali‐silica reaction (ASR) is particularly high. This concerns especially concrete pavements due to the increasing heavy load traffic and the wintry application of NaCl deicer. Notably the role of a mechanical pre‐damage of concrete caused by traffic loadings on the course of the ASR is largely unclear. A part of the investigations that has been conducted since 2012 into this issue within the scope of the DFG (German research foundation) funded research group 1498 shall be introduced in the following. It was evident that an ASR in defined mechanically pre‐damaged concrete prisms with alkali‐reactive aggregates and under an external supply of alkalis started earlier than in equal prisms without a pre‐damage. The reason for this is the faster and deeper ingress of water and particularly of dissolved NaCl into the concrete, by what Na ions as reaction partner for an ASR are available earlier and, in the long‐term, in greater amounts too.
Selective Separation of Toluene/n‐Heptane by Supported Ionic Liquid Membranes with [Bmim][BF4]
Authors: Zhang Fan , Feng Hao , Sun Wei , Zhang Weidong , Liu Junteng , Ren Zhongqi 
Published: January 2015

AbstractRoom‐temperature ionic liquids serve as alternative solvents for volatile organic compounds in liquid‐liquid extraction and liquid membrane separation. 1‐Butyl‐3‐methylimidazolium tetrafluoroborate ([Bmim][BF4]) was applied for extraction and supported ionic liquid membranes (SILMs) to separate toluene and n‐heptane. A high separation factor of toluene was achieved due to the strong interaction between ionic liquid cations and toluene. The mass transfer performance of the SILM process was enhanced by higher operating temperature. With the increase of initial toluene concentration in the feed phase, the mass transfer flux and removal efficiency of the SILM process were improved, while the separation factor decreased. The mass transfer flux was growing with the increase of flow rate at both sides. The SILM process was stable over a long time period due to the high viscosity and low volatility of [Bmim][BF4].
Study of an Annular Photoreactor with Tangential Inlet and Outlet: I. Fluid Dynamics
Authors: Peres José Carlos G. , Silvio Uirá de , Teixeira Antonio Carlos S. C. , Guardani Roberto , Jr. Ardson dos S. Vianna 
Published: January 2015

AbstractPhotochemical reactors tend to exhibit turbulent flow even with low Reynolds numbers. The k‐ϵ model is not always appropriate in this situation. An annular photoreactor was designed with tangential inlet and outlet tubes to investigate this. The fluid flow was characterized by residence time distribution (RTD) experiments, which were reproduced by computational fluid dynamics considering four relevant turbulence models: the k‐ϵ, the k‐ω, the shear stress transport, and the Reynolds stress models. Inlet effects induced helical flow throughout the reactor, switching to plug flow depending on the flow rate and the turbulence model. The k‐ω model properly deals with viscous effects and reproduces the experimental RTD curves with correlation coefficients greater than 0.9566, against 0.8705 from the k‐ϵ model.
Enantioselective Organocatalytic Reduction of β‐Trifluoromethyl Nitroalkenes: An Efficient Strategy for the Synthesis of Chiral β‐Trifluoromethyl Amines
Authors: Massolo Elisabetta , Benaglia Maurizio , Orlandi Manuel , Rossi Sergio , Celentano Giuseppe 
Published: January 2015

AbstractAn efficient organocatalytic stereoselective reduction of β‐trifluoromethyl‐substituted nitroalkenes, mediated by 3,5‐dicarboxylic ester‐dihydropyridines (Hantzsch ester type), has been successfully developed. A multifunctional thiourea‐based (S)‐valine derivative was found to be the catalyst of choice, promoting the reaction in up to 97 % ee. The methodology has been applied to a wide variety of substrates, leading to the formation of differently substituted precursors of enantiomerically enriched β‐trifluoromethyl amines. The mechanism of the reaction and the mode of action of the metal‐free catalytic species were computationally investigated; on the basis of DFT transition‐state (TS) analysis, a model of stereoselection was also proposed.

Published: January 2015

AbstractThree‐dimensional (3D) nanometal films serving as current collectors have attracted much interest recently owing to their promising application in high‐performance supercapacitors. In the process of the electrochemical reaction, the 3D structure can provide a short diffusion path for fast ion transport, and the highly conductive nanometal may serve as a backbone for facile electron transfer. In this work, a novel polypyrrole (PPy) shell@3D‐Ni‐core composite is developed to enhance the electrochemical performance of conventional PPy. With the introduction of a Ni metal core, the as‐prepared material exhibits a high specific capacitance (726 F g−1 at a charge/discharge rate of 1 A g−1), good rate capability (a decay of 33 % in Csp with charge/discharge rates increasing from 1 to 20 A g−1), and high cycle stability (only a small decrease of 4.2 % in Csp after 1000 cycles at a scan rate of 100 mV s−1). Furthermore, an aqueous symmetric supercapacitor device is fabricated by using the as‐prepared composite as electrodes; the device demonstrates a high energy density (≈21.2 Wh kg−1) and superior long‐term cycle ability (only 4.4 % and 18.6 % loss in Csp after 2000 and 5000 cycles, respectively).
