<div class="section abstract"><div class="htmlview paragraph">The performance of a commercial Cu-zeolite SCR catalyst after differing degrees of hydrothermal aging (aged for 72 hours at 500, 700 and 800°C with 10% moisture balanced with air) was studied by spatially resolving different key reactions using…
$\ensuremath{\kappa}$-(BEDT-TTF)${}_{2}$Cu(NCS)${}_{2}$ [BEDT-TTF: bis-(ethylenedithio)-tetrathiafulvalene] behaves as a semiconductor at high temperatures, whereas it behaves as a Fermi liquid just above the superconducting transition temperature. To reveal the cause of this behavior, we experimented on $\ensuremath{…
<div class="section abstract"><div class="htmlview paragraph">Advanced High Strength Steels (AHSS) have been implemented in the automotive industry to balance the requirements for vehicle crash safety, emissions, and fuel economy. With lower ductility compared to conventional steels, the fracture behavior…
<div class="section abstract"><div class="htmlview paragraph">The demands for improved fuel economy, performance and emissions continue to pose challenges for engine designers and the materials they choose. The present paper provides a review of the properties of Compacted Graphite Iron (CGI), gray cast ir…
Y‐doped (1− x mol%)BaTiO 3 – x mol%(Bi 1/2 Na 1/2 )TiO 3 (BBNT x ) lead‐free positive temperature coefficient of resistivity (PTCR) ceramics were prepared using a conventional solid sintering method. The Ba/Ti ratio was adjusted to obtain the optimized PTCR property. The results show that all 0.2 mol% Y‐doped BBNT15 s…
Abstract In this article, the nonlinear optical (NLO) switching action of Ru(III/II) carboxylate complexes was investigated by density functional theory (DFT). Among the studied complexed, Ru(III)PhCOO − has the largest β value of 4972 × 10 −30 esu. Through the proton transfer (PT) process, the COOH group of Ru(III)P…
The use of Expanded Polyolefin foams including Expanded Polypropylene (EPP) material for interior applications has grown over the years to include applications throughout the vehicle. The demand for weight and cost reduction has forced designers to seek out the most versatile material available to satisfy the need for…
Bismuth telluride (Bi2Te3) is an attractive material for both thermoelectric and topological insulator applications. Its performance is expected to be greatly improved when the material takes nanowire structures. However, it is very difficult to grow high-quality Bi2Te3 nanowires. In this study, a simple and reliable…
Photocurrent spectroscopy has been carried out on single CdS nanosheet devices in the metal-semiconductor-metal configuration with both Schottky and Ohmic contacts. Spatial imaging of the photocurrent shows that the photosensitive regions are localized at the reverse biased contact for Schottky type contacts and unifo…
This report presents the microwave characteristics of conducting polymer composites (CPCs) based on chloroprene rubber with special reference to dielectric properties. CPCs based on polyaniline (PANI), polyaniline-coated short nylon fiber (PANI-N) and chloroprene rubber (CR) were prepared by mechanical mixing. The imp…
Abstract Red, transparent single crystals of molybdenum(VI) dioxide dibromide MoO 2 Br 2 emerged as by‐product after thermal analyses of reaction mixtures comprising RE Br 3 ( RE = La or Gd) and MoO 3 . The structure of this highly water sensitive compound can be described in the non ‐centrosymmetric monoclinic space…
In order to prepare cured thin films thicknesses in the range of 90−300 nm, epoxy−amine mixtures of different concentrations in toluene are spin-cast onto oxidized silicon substrates. The glass transition temperature of the cured thin films is measured by microthermal analysis, revealing the existence of two distinct…
Conducting polymers (CPs) have attracted a great deal of attention due to their unique properties; these properties are useful in implementing various functional devices, such as memory, and chemical and biological sensors. In particular, the nanopatterning of CPs is a key technology that will accelerate the adoption…
<div class="section abstract"><div class="htmlview paragraph">For the removal of NOx from the oxygen-rich diesel exhaust in mobile applications the selective catalytic reduction (SCR) is one of the most favored technologies. Well established NH₃-SCR technique uses either V₂O₅/WO₃-TiO₂ or Zeolite-based cata…
<div class="section abstract"><div class="htmlview paragraph">The emission regulations for mobile off-road applications are following on-road trends by a short delay. The latest Stage 3B and 4 emission limits mean a gradual implementation of oxidation and SCR catalysts as well as particulate filters with o…
We present the results of coarse grained molecular dynamics simulation using a charge free model that is able to capture different regions of the morphological phase diagram of charged diblock copolymers. Specifically, we were able to reproduce many phases of the poly(acrylic acid)-(1,4)-polybutadiene (PAA-PBA) dibloc…
<div class="section abstract"><div class="htmlview paragraph"> Diesel NOx emissions control utilizing combined Lean NOx Trap (LNT) and so-called passive or in-situ Selective Catalytic Reduction (SCR) catalyst technologies (i.e. with reductant species generated by the LNT) has been the subject of several pr…
This study demonstrates a tunable Fresnel lens in an azo-dye-doped liquid crystal (ADDLC) film using an interference technique. One Fresnel-patterned green beam using a Sagnac interferometer irradiated the UV-illuminated ADDLC cell, yielding a concentric zone plate distribution with homeotropic and isotropic structure…
A particle mesh Ewald (PME) Stokesian dynamics algorithm has been developed to model hydrodynamic interactions in suspensions of non-spherical dicolloidal particles. Dicolloids, which have recently been synthesized by a number of independent research groups (Johnson, van Kats & van Blaaderen ( Langmuir , vol. 21,…
Large ZnO mesocrystals of hexagonal columnar morphology have been successfully synthesized by using liquid crystals (LCs) of cetyltrimethylammonium bromide (CTAB, CH 3 (CH 2 ) 15 N + (CH 3 ) 3 Br − ) as templates. The LC‐templated growth process is established by monitoring the crystal morphology, phase evolution at v…
