The mechanical properties of soft tissues depend on the collagen fiber network and the surrounding non-fibrillar matrix. The mechanical role of non-fibrillar material remains poorly understood. Our recent study (Lake and Barocas, Ann Biomed Eng 2011) introduced collagen-agarose co-gels as a simple experimental model s…
The Fe-vacancy ordering patterns in the superconducting K x Fe 2– y Se 2 and nonsuperconducting K x (Fe,Co) 2– y Se 2 samples have been investigated by electron diffraction and high angle annular dark field scanning transmission electron microscopy. The Fe-vacancy ordering occurs in the ab plane of the parent ThCr 2 S…
Vehicle modernization has been developed towards the growing necessities of speed, power, efficiency, ergonomics, and design etc. The requirements, nowadays of environmental safety and operational efficiency of vehicles are being brought to the forefront. The aim of this work is to increase efficiency and reduce the h…
<div class="section abstract"><div class="htmlview paragraph">Stringent global emissions legislation demands effective NOx reduction strategies, particularly for the aftertreatment, and current typical liquid urea SCR systems achieve efficiencies greater than 90% [<span class="xref">1</span>].…
Here we report the syntheses and crystal structures of a series of cobalt(II) and nickel(II) complexes derived from (R)NP2 ligands (where R = OMe(Bz), H(Bz), Br(Bz), Ph) bearing ethylene linkers between a single N and two P donors. The Co(II) complexes generally adopt a tetrahedral configuration of general formula [(N…
Fluorescence indicator/layered double hydroxide (LDH) ultrathin films (UTFs) have been fabricated by alternate assembly of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) and Zn–Al LDH nanosheets on quartz substrates using the layer-by-layer (LBL) deposition technique and demonstrated to be good fluorescence…
We demonstrate a purely solvent-based approach to assembling CdSe nanorods into vertically aligned, hexagonally packed monolayers in solution. Nanorods were dispersed in a mixture of good solvent with high vapor pressure and bad solvent with low vapor pressure, and preferential evaporation of the good solvent led to o…
We prove that any limit-interface corresponding to a locally uniformly bounded, locally energy-bounded sequence of stable critical points of the van der Waals–Cahn–Hilliard energy functionals with perturbation parameter → 0 + is supported by an embedded stable minimal hypersurface which in low dimensions has no singul…
We report on the structure, uniaxial orientation, and photoluminescent properties of CdS nanorods that form stable nanocomposites with smectic C hydrogen-bonded polymers from the family of poly(4-(n-acryloyloxyalkoxy)benzoic acids. TEM analysis of microtomed films of nanocomposites reveals that CdS nanorods form small…
Abstract In this paper, the dynamic mechanical properties of the natural rubber (NR) which was filled with in situ zinc dimethacrylate (ZDMA) were investigated using a Rubber Process Analyzer (RPA2000). A weak rigid filler–filler network was formed in the uncured NR/ZDMA compounds. Pronounced Payne effect and stress‐s…
We report on original nonlinear spectral hole-burning experiments in single wall carbon nanotubes that bring evidence of pure dephasing induced by exciton-exciton scattering. We show that the collision-induced broadening in carbon nanotubes is controlled by exciton-exciton scattering as for Wannier excitons in inorgan…
Using the density functional theory with the generalized gradient approximation, we have examined the stability and the catalytic properties of Au 16 gold cage structure supported on graphane. The substantially improved stability is confirmed by the first-principles molecular dynamics simulation at the temperature abo…
Trinuclear heterobimetallic Ln(III)-Ru(II) complexes (Ln = Eu, Gd) based on a 1,10-phenanthroline ligand bearing a diethylenetriaminepentaacetic acid (DTPA) core have been synthesized and fully characterized by a range of experimental techniques. The (17)O NMR and proton nuclear magnetic relaxation dispersion (NMRD) m…
Hot off the wire: Scanning tunneling microscopy, X-ray photoelectron spectroscopy, and density functional calculations were used to study the interaction of RuO2 nanostructures with TiO2(110). Ruthenium oxide forms unique Ru3O6 wire-like structures on TiO2 that can be easily reduced and re-oxidized at temperatures in…
Investigation of the interactions between cells and material surfaces is important not only for the understanding of cell biology but also for the development of smart biomaterials. In this study, we investigated the substrate-related effects on the interaction between cell and polymeric ultrathin film (nanosheet) by…
Ag/Cu bimetallic nanocatalysts supported on reticulate‐like γ ‐alumina were prepared by a microemulsion method using N 2 H 4 · H 2 O as the reducing agent. The catalysts were activated by calcination followed with hydrogen reduction at 873K, and the properties were confirmed using various characterization techniques.…
Wachstumsschub: Ein einfacher Weg wurde gefunden, um das anisotrope Wachstum von TiO2 auf unterschiedlich geformten Goldnanopartikeln in Richtung Janus-, exzentrischer oder konzentrischer Geometrie zu steuern (siehe Bild). Die Au-TiO2-Janus-Nanostrukturen sind nach Berechnungen energetisch stabil, und sie sind dank de…
Hyper-networked Li(4)Ti(5)O(12)/carbon hybrid nanofiber sheets that contain both a faradaically rechargeable battery-type component, namely Li(4)Ti(5)O(12), and a non-faradaically rechargeable supercapacitor-type component, namely N-enriched carbon, are prepared by electrospinning and their dual function as a negative…
Single-phase Bi(0.80)La(0.20)FeO(3) (BLFO) and Bi(0.80)La(0.20)Fe(1-x)Nb(x)O(3) (BLFNO) samples were prepared in order to study the dielectric, magnetic and magnetoelectric properties of La and Nb codoped BiFeO3. Rietveld refinement of x-ray diffraction patterns of La and Nb codoped samples has been performed using th…
Crystallization of poly(ethylene oxide) (PEO) induced by extensional flow has been studied by in-situ small-angle X-ray scattering (SAXS). A constant Hencky strain was applied to the melt with strain rates varying in 3 orders of magnitude. The evolution of the long period with crystallization time is qualitatively dif…
