Chemical Vapor Detection Using a Reconstituted Insect Olfactory Receptor Complex
Authors: Sato Koji , Takeuchi Shoji 
Published: July 2014

AbstractThe sensing of vapor odorants is highly demanded in the field of life and medical sciences. Although olfactory receptors (ORs) have potentials to recognize volatile organic compounds, the interaction of ORs, chemical vapors, and peptide components in olfactory mucus has yet to be analyzed to develop OR‐based sensors. A bioinspired electrophysiology technique is shown to record the response of reconstituted insect ORs to chemical vapors. To mimic the interface between ORs and olfactory mucus, OR expressing spheroids were loaded into a hydrogel microchamber array. A negative extracellular field potential shift of spheroids was successfully observed by the stimulation of their vapor cognate ligand. Importantly, the ligand repertoire of the OR of malaria vector mosquito examined by this method differed from that of in vivo studies. Our method is useful to develop protein‐based gas sensing techniques and to examine the binding of ORs and chemical vapors.
The Hydrophobic Effect Revisited—Studies with Supramolecular Complexes Imply High‐Energy Water as a Noncovalent Driving Force
Authors: Biedermann Frank , Nau Werner M. , Schneider Hans‐Jörg 
Published: July 2014

AbstractTraditional descriptions of the hydrophobic effect on the basis of entropic arguments or the calculation of solvent‐occupied surfaces must be questioned in view of new results obtained with supramolecular complexes. In these studies, it was possible to separate hydrophobic from dispersive interactions, which are strongest in aqueous systems. Even very hydrophobic alkanes associate significantly only in cavities containing water molecules with an insufficient number of possible hydrogen bonds. The replacement of high‐energy water in cavities by guest molecules is the essential enthalpic driving force for complexation, as borne out by data for complexes of cyclodextrins, cyclophanes, and cucurbiturils, for which complexation enthalpies of up to −100 kJ mol−1 were reached for encapsulated alkyl residues. Water‐box simulations were used to characterize the different contributions from high‐energy water and enabled the calculation of the association free enthalpies for selected cucurbituril complexes to within a 10 % deviation from experimental values. Cavities in artificial receptors are more apt to show the enthalpic effect of high‐energy water than those in proteins or nucleic acids, because they bear fewer or no functional groups in the inner cavity to stabilize interior water molecules.

Published: July 2014

AbstractThe immobilization of bioactive molecules onto nanocellulose leads to constructs that combine the properties of the grafted compounds with the biocompatibility and low cytotoxicity of cellulose carriers and the advantages given by their nanometer dimensions. However, the methods commonly used for protein grafting suffer from lack of selectivity, long reaction times, nonphysiological pH ranges and solvents, and the necessity to develop a tailor‐made reaction strategy for each individual case. To overcome these restrictions, a generic two‐step procedure was developed that takes advantage of the highly efficient oxime ligation combined with enzyme‐mediated protein coupling onto the surface of peptide‐modified crystalline nanocellulose. The described method is based on efficient and orthogonal transformations, requires no organic solvents, and takes place under physiological conditions. Being site‐directed and regiospecific, it could be applied to a vast number of functional proteins.
Improving the metal ion release from nanoparticles embedded in a polypropylene matrix for antimicrobial applications
Authors: Palza Humberto , Delgado Katherine , Pinochet Ivette 
Published: July 2014

ABSTRACTNovel antimicrobial materials can be produced by adding copper nanoparticles (CNPs) into a polymeric matrix. To improve the behavior of these systems, the effect of different variables on the dispersion of copper metal nanoparticles embedded in a polypropylene matrix by melt mixing and its ion release was analyzed. The variables studied were predispersion of particles in liquid solvents, polymer molecular weight, melt mixing conditions, addition of a compatibilizer agent, two‐step melt mixing, and surface functionalization of the metal particles. Our results show that by modifying these variables, a significant improvement in the filler dispersion, as quantified by optical microscope, can be obtained. For instance, the original CNP agglomerates can be reduced from an average size of 70 µm to a final average size of 30 µm and a larger amount of nanometric agglomerates by using a compatibilizer or predispersed nanoparticles. Moreover, by using surface‐functionalized CNPs, micrometric agglomerates were not observed. Noteworthy, there is a direct relationship between the filler dispersion and the release of biocide copper ions when improvements were larger than a certain threshold with increases as high as 40%. These findings can be used in the development of antimicrobial materials with tailored behavior. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41232.
Ephrin‐A3 and Ephrin‐A4 Contribute to Microglia‐Induced Angiogenesis in Brain Endothelial Cells

Published: July 2014

ABSTRACTThe association of microglia with brain vasculature during development and the reduced brain vascular complexity in microglia‐deficient mice suggest the role of microglia in cerebrovascular angiogenesis. However, the underlying molecular mechanism remains unclear. Here, using an in vitro angiogenesis model, we found the culture supernatant of BV2 microglial cells significantly enhanced capillary‐like tube formation and migration of brain microvascular endothelial cells (BMECs). The expression of angiogenic factors, ephrin‐A3 and ephrin‐A4, were specifically upregulated in BMECs exposed to BV2‐derived culture supernatant. Knockdown of ephrin‐A3 and ephrin‐A4 in BMECs by siRNA significantly attenuated the enhanced angiogenesis and migration of BMECs induced by BV2 supernatant. Our further results indicated that the ability of BV2 supernatant to promote endothelial angiogenesis was caused by the soluble tumor necrosis factor α (TNF‐α) released from BV2 microglial cells. Moreover, the upregulations of ephrin‐A3 and ephrin‐A4 in BMECs in response to BV2 supernatant were effectively abolished by neutralization antibody against TNF‐α and TNF receptor 1, respectively. The present study provides evidence that microglia upregulates endothelial ephrin‐A3 and ephrin‐A4 to facilitate in vitro angiogenesis of brain endothelial cells, which is mediated by microglia‐released TNF‐α.

AbstractReactions of 5‐ethyl 5H‐1,2,4‐triazino|5,6‐b|indol‐3‐thione (1) with various reagents have been studied. 1 and hydrazine hydrate in anhydrous ethanol gave 5‐ethyl‐3‐hydrazino‐5H‐1,2,4‐triazino|5,6‐b|indole (2). This compound was condensed with formic acid and acetic acid to give 10‐ethyl‐10H‐|1,2,4|triazolo|3′,4′:3,4||1,2,4|triazino|5,6‐b|indole (4, R=H) and 10‐ethyl‐1 ‐methyl‐10H‐|1,2,4|triazolo‐|3′,4′:3,4‖ 1,2,4|triazino|5,6‐b|indole (4, R = CH3), respectively. Treatment of 2 with nitrous acid gave 10‐ethyl‐10H‐tetrazolo|5′,1′:3,4‖ 1,2,4|triazino|5,6‐b|indole (7). Interaction of 2 with acetylacetone in alcoholic KOH gave the pyrazole 8, whereas reaction of 2 with ethyl acetoacetate in anhydrous ethanol led to the expected hydrazone 9, which on reflux with alcoholic KOH gives 1‐(5‐ethyl‐5H‐1,2,4‐triazino| 5,6‐b|indol‐3‐yl)‐3‐methyl‐2‐pyrazolin‐5‐one 10.

Freeze‐Drying‐Assisted Synthesis of Hierarchically Porous Carbon/Germanium Hybrid for High‐Efficiency Lithium‐Ion Batteries
Authors: Xiao Ying , Cao Minhua 
Published: July 2014

AbstractHerein, an approach is reported to prepare porous a carbon/Ge (C/Ge) hybrid. In this hybrid, Ge nanoparticles are closely embedded in a highly conductive and flexible carbon matrix. Such a hybrid features a high surface area (128.0 m2 g−1) and a hierarchical micropore–mesopore structure. When used as an anode material in lithium‐ion batteries (LIBs), the as‐prepared hybrid [C/Ge (60.37 %)] exhibits an improved lithium storage performance with regard to its capacity and rate capability compared to its counterparts. More specifically, it can maintain a specific capacity as high as 906 mAh g−1 at a high current density of 0.6 A g−1 after 50 cycles. The excellent lithium storage performance of the C/Ge (60.37 %) sample can be attributed to synergetic effects between the carbon matrix and Ge nanoparticles. The method we adopted is simple and effective, and can be extended to fabricate other nanomaterials.
An agent‐based simulation model to assess the impacts of introducing a shared‐taxi system: an application to Lisbon (Portugal)
Authors: Martinez Luis M. , Correia Gonçalo H. A. , Viegas José M. 
Published: July 2014

SummaryThis paper presents a new concept of urban shared‐taxi services. The proposed system has a new organisational design and pricing scheme that aims to use the capacity in traditional taxi services in a more efficient way. In this system, a taxi acting in ‘sharing’ mode offers lower prices to its clients, in exchange for them to accept sharing the vehicle with other persons who have compatible trips (time and space). The paper proposes and tests an agent‐based simulation model in which a set of rules for space and time matching between a request of a client and the candidate shared taxis is identified. It considers that the client is only willing to accept a maximum deviation from his or her direct route and establishes an objective function for selecting the best candidate taxi. The function considers the minimum travel time combination of pickup and drop‐off of all the pool of clients sharing each taxi while allowing to establish a policy of bonuses to competing taxis with certain number of occupants. An experiment for the city of Lisbon is presented with the objectives of testing the proposed simulation conceptual model and showing the potential of sharing taxis for improving mobility management in urban areas. Results show that the proposed system may lead to significant fare and travel time savings to passengers, while not jeopardising that much the taxi revenues. Copyright © 2014 John Wiley & Sons, Ltd.
Realistic and stable simulation of turbulent details behind objects in smoothed‐particle hydrodynamics fluids
Authors: Shao Xuqiang , Zhou Zhong , Zhang Jinsong , Wu Wei 
Published: July 2014

AbstractThis paper presents a novel realistic and stable turbulence synthesis method to simulate the turbulent details generated behind objects in smoothed particle hydrodynamics (SPH) fluids. Firstly, by approximating the boundary layer theory on the fly in SPH fluids, we propose a vorticity production model to identify which fluid particles shed from object surfaces and which are seeded as vortex particles. Then, we employ an SPH‐like summation interpolant formulation of the Biot–Savart law to calculate the fluctuating velocities stemming from the generated vorticity field. Finally, the stable evolution of the vorticity field is achieved by combining an implicit vorticity diffusion technique and an artificial dissipation term. Moreover, in order to efficiently catch turbulent details for rendering, we propose an octree‐based adaptive surface reconstruction method for particle‐based fluids. The experiment results demonstrate that our turbulence synthesis method provides an effect way to model the obstacle‐induced turbulent details in SPH fluids and can be easily added to existing particle‐based fluid–solid coupling pipelines.

Mn3O4/Carbon Nanotube Nanocomposites as Electrocatalysts for the Oxygen Reduction Reaction in Alkaline Solution
Authors: Huang Dekang , Zhang Bingyan , Li Shaohui , Wang Mingkui , Shen Yan 
Published: July 2014

AbstractElectrodes based on helical carbon nanotubes (CNTs) and Mn3O4 nanocomposites are investigated for catalysis of the oxygen reduction reaction (ORR) in alkaline solutions. Modification of Mn3O4 with helical CNTs allows these nanocomposite materials to exhibit high catalytic activity for the ORR, in which a four‐electron pathway dominates, and also remarkable stability in air‐saturated alkaline solutions. These properties are attributed to a combination of fast electron transport by the helical CNTs and high catalytic activity of Mn3O4 in the ORR.

AbstractTheN,N′‐bis[(3‐hydroxy‐4‐pyron‐2‐yl)methyl]‐N,N′‐dimethylethylendiamine (Malten=L) forms the highly stable [CuH−2L] species in water, in which the converging maltol oxygen atoms form an electron‐rich area able to host hard metal ions. When considering the alkaline earth series (AE), the [Cu(H−2L)] species binds all metal ions, with the exception of Mg2+, exhibiting the relevant property to discriminate Ca2+versus Mg2+at physiological pH 7.4; the binding of the AE metal is visible to the naked eye. The stability constant values of the trinuclear [AE{Cu(H−2L)}2]2+species formed reach the maximum for Ca2+(log K=7.7). Ca2+also forms a tetranuclear [Ca{Cu(H−2L)}]24+species at a high Ca2+concentration. Tri‐ and tetranuclear calcium complexes show blue‐ and pink‐colored crystals, respectively. [Cu(H−2L)] is the most active species in inducing DNA alterations. The DNA damages are compatible with its hydrolytic cleavages.
