Diesel engines typically require diesel particulate filter (DPF) systems to reduce particulate matter (PM) emissions in order to meet increasingly stringent emission regulations. While there have been noticeable advances in DPF technology, significant efforts are still needed to develop optimum DPF regeneration strate…
Abstract Delta doping of diamond constitutes a very promising route to fabricate novel generation of high power and high frequency electronic devices. However, the achievement of abrupt interfaces between highly boron doped and undoped layers requires the shortest residence times of reactive species in the substrate v…
The structure–property relationships for the n = 2 member (Ba 3 Co 10 O 17 ) of the [BaCoO 3 ] n [BaCo 8 O 11 ] modular family have been studied by comparison to the n = 1 term (Ba 2 Co 9 O 14 ). It orders antiferromagnetically at T N = 62 K with spin ordering in the common [BaCo 8 O 11 ] units similar to that for n =…
An automatic registration of the changing size of a single spherical microbead of a cross-linked polymer was applied for studying the swelling process of the bead by the sorption of vapors and/or liquids. Many representatives of all three basic types of polymeric networks, gel-type, hypercrosslinked, and macroporous,…
Density functional theory-based calculations of the (10,0) zigzag single-walled carbon nanotube with hydrogen chemisorbed exohedrally show that electron pairing and strain minimization lead hydrogen atoms to cluster and preferentially sit in axial configurations. This tendency to confine in highly ordered configuratio…
In this article, a numerical method to predict textile geometry is derived using a technique based on finite elements (FEs). A geometric modeling package is used to represent an initial geometry of the yarns within the textile. The yarn mid-surface is then represented using plate elements, with the yarn thickness and…
Using density functional theory, the generalized gradient approximation for the exchange-correlation potential and Møller-Plesset perturbation theory we study the hydrogen uptake of Li- and Mg-doped boranes. Specifically, we calculate the structures and binding energies of hydrogen molecules sequentially attached to L…
Abstract An in situ lubrication dispersion method is developed to achieve electrical conductivity in PP containing a small amount of MWCNTs. Good dispersion of the MWCNTs in PP is observed even after a short mixing time because the interactions between the entangled nanotubes are reduced. By in situ lubrication disper…
Atomic layer deposition (ALD) has proven to be an excellent candidate for the deposition of thin layers onto various nanostructures to create core-shell structures with new functionalities and improved device application potential. The authors have used ALD to fabricate metal oxide core-shell nanowires based on electr…
An oriented array of electron transporting nanowires, grown directly on a transparent conductor constitutes an optimal architecture for efficient photovoltaic applications. In addition, semiconductor nanocrystals can work as efficient light absorbers because of their tunable optical properties. In this paper, we use a…
Abstract Nowadays the economic recycling of waste tires has become a global challenge. The use of waste tire powder as a dispersed elastomeric phase in a polypropylene (PP) matrix offers an interesting opportunity for recycling of waste tire rubber. Compatibilized PP/(waste tire powder) composites are microcellularly…
Surface‐enhanced resonance Raman scattering (SERRS) spectroscopy is a powerful tool for the selective and sensitive detection of porphyrins. We report a repeatable detection of unperturbed free base 5,10,15,20‐tetrakis(1‐methyl‐4‐pyridyl)21 H ,23 H ‐porphine in concentrations as low as 1 × 10 –13 M in the final system…
Non-branching twinned Ag nanowires have been synthesized within a three-dimensional electrochemical deposition system by using a non-supporting electrolyte and an unusually high over-potential. The branching rate of the Ag nanowires is significantly decreased under the interactions of a strong applied potential and th…
We simulate the ultrafast dynamics of laser-induced coherent phonons in single-wall carbon nanotubes (SWNTs). In particular, we examine the coherent phonon amplitude of the radial breathing mode (RBM) as a function of excitation energy and chirality. We find that the RBM coherent phonon amplitudes are very sensitive t…
The effective removal of o-cresol is currently both an environmental and economic challenge. ZnO is not only an efficient photocatalyst but is also cost effective, as its photoabsorption can extend from the ultraviolet (UV) to the visible range thereby allowing the use of inexpensive visible light sources, such as sun…
Abietic acid was isolated from rosin by means of reaction-crystallization coupled with exposure to ultrasonic waves, and it was then characterized by its specific rotation, infrared spectra, and 13 C nuclear magnetic resonance spectra. The thermal decomposition of abietic acid in argon atmosphere was studied under non…
The adsorption on hydrophobic and hydrophilic silica-based surfaces of the integrin-binding PHSRN peptide and the single-residual-mutated analogues, PHSEN and PHSFN, is investigated by comparative QCM-D, XPS, SFG measurements and molecular dynamics calculations. Endothelial cell cultures on the peptide-functionalized…
ZnS nanocombs were fabricated via a two-step growth method. By annealing Au coated ZnS nanobelts with the help of SnO2/C, comb-like nanostructures would be formed. In the absence of SnO2/C, Au coated ZnS nanobelts would be evaporated completely at the same temperature. As revealed by high resolution transmission micro…
The microstructural and crystallographic characteristics of 5M martensite in an Ni 50 Mn 28 Ga 22 alloy were investigated by electron backscatter diffraction (EBSD) analysis. The microstructure of 5M martensite observed at room temperature can be characterized by broad plates with alternately distributed fine lamellae…
The synthesis of novel poly(butylene dodecanoate)s containing different percentages of glycerol was successfully carried out. The polyesters are characterized by branched or cross-linked molecular structures, according to the glycerol content. The modification of the linear backbone of the poly(butylene dodecanoate) i…
