<div class="section abstract"><div class="htmlview paragraph">Despite drastic reduction of sulfur content in diesel fuel in the recent years, especially with the introduction of Ultra-Low Sulfur Diesel (ULSD), sulfur poisoning remains one of the most significant factors impacting performance of various cat…
(0.98-x)Bi(Sc3/4In1/4)O3-xPbTiO3-0.02Pb(Zn1/3Nb2/3)O3 (BSI-PT-PZN) high temperature piezoelectric ceramics were prepared by traditional solid-state reaction method. Combining X-ray diffraction results with piezoelectric data, it was found that the morphotropic phase boundary (MPB) occurred at x = 0.575. The piezoelect…
Abstract Hydrochloric acid (HCl) is commonly used to remove wellbore damage and to enhance near-wellbore formation permeability in carbonate formations. Although in most cases the spent acid is recovered rapidly during well flow back after the treatment, in heterogeneous reservoirs some of the spent acid can remain tr…
Graphene nanomeshes (GNMs) are expected to be a high-performance channel material for metal-oxide-semiconductor field-effect-transistors (MOSFETs), since they can open up a band gap in a large sheet of graphene thin film by simply introducing two-dimensional periodical nanoscale holes. In this paper, we theoretically…
<div class="section abstract"><div class="htmlview paragraph">In the automotive industry, the piezo-based in-cylinder pressure sensor is getting commercialized and used in production vehicles. For example, the pressure sensor offers the opportunity to design algorithms for estimation of engine emissions, such as soot…
Manganese nitride films are grown by low-pressure chemical vapor deposition from the novel precursor bis[di(tert-butyl)amido]manganese(II) and ammonia. Mixed-phase films containing crystalline manganese nitride can be grown on substrates at temperatures as low as 80 °C. Above 200 °C, the films consist entirely of crys…
Abstract Phosphonate scale inhibitors (SIs) applied in downhole squeeze applications may be retained in the near-well formation through adsorption and/or precipitation mechanisms. In this paper, we focus on the properties of precipitated calcium phosphonate complexes formed by 9 common phosphonate species. The stoichi…
Mit Ecken und Kanten: Die Bindungsenergie von Sauerstoff auf Pd-Partikeln wurde mit einer direkten kalorimetrischen Methode als Funktion der Partikelgröße gemessen. Die reduzierte räumliche Ausdehnung der Partikel resultierte in zwei entgegengesetzten Trends: 1) Anstieg der Pd-O-Bindungsenergie aufgrund der Änderung d…
The Au 102 ( p -MBA) 44 ( p -MBA = para -mercaptobenzoic acid) nanocluster is an ideal model to study the structures of gold nanoclusters, the motifs of the monolayer ligand groups, and the crystal formation of Au nanoparticles. Based on the partially exchanged Au 102 ( p -MBA) 40 ( p -BBT) 4 ( p -BBT = para -bromoben…
Abstract Batch corrosion inhibition has been a technique used for many decades. Often, a non-structured philosophy is taken to treat downhole production tubing and pipelines using batch treatment. This results in non-optimal chemistries and application parameters being employed, resulting in dubious protection being p…
Abstract As the oil and gas industry is making firm stride in deepwater exploration and development, possible thermal degradation of scale inhibitor molecules poses a great challenge for scaling control and flow assurance for high temperature reservoirs. Although extensive research has been conducted to test thermal s…
<div class="section abstract"><div class="htmlview paragraph">The Environmental Protection Agency (EPA) and Department of Transportation's National Highway Traffic Safety Administration (NHTSA) have finalized regulation that will reduce greenhouse gases and increase fuel economy for model year (MY) 2012-20…
<div class="section abstract"><div class="htmlview paragraph">The reduction of NOx in exhaust gas has been a major challenge in diesel engine development. For the NOx reduction issues, a new Lean NOx Catalyst (LNC) aftertreatment system has been developed by Honda. A feature of the LNC system is the method…
Nowadays, the absorbed dose to water for kilovoltage x-ray beams is determined from standards in terms of air-kerma by application of international dosimetry protocols. New standards in terms of absorbed dose to water has just been established for these beams at the LNE-LNHB, using water calorimetry, at a depth of 2 c…
<div class="section abstract"><div class="htmlview paragraph">Diesel emission regulation becomes stringent more and more regarding both particulate matter (PM) and NOx in the worldwide. SCR coated DPF system is considered as one of the promising options for future diesel exhaust after-treatment because it…
ZnCdO nanowires with up to 45% Cd are demonstrated showing room temperature photoluminescence (PL) down to 2.02 eV and a radiative efficiency similar to that of ZnO nanowires. Analysis of the microstructure in individual nanowires confirms the presence of a single wurtzite phase even at the highest Cd contents, with a…
Knowing the yarn-strength performance potential of cotton fibre is advantageous to spinners during mill preparation, and to researchers developing new genotypes and management strategies to produce better fibre. Standard High Volume Instrument (HVI) fibre quality attributes include micronaire (a combined measure of fi…
A polymer-stabilised blue-phase liquid crystal display (PSBP-LCD) with double-sided protrusion (DSP) electrodes structure is proposed. The oblique electric field between the protrusion electrodes inside both top and bottom glass substrates can induce more isotropic-to-anisotropic transition in the polymer-stabilised b…
(Ga,Mn)As nanowires were grown by molecular beam epitaxy using Mn as a growth catalyst on GaAs(001) substrates at 485 °C, i.e., at intermediate temperatures higher than ones used for the growth of (Ga,Mn)As thin films, but lower than the ordinary temperatures of Au-assisted growth of GaAs nanowires. (Ga,Mn)As nanowire…
Hydrophilization of carbon nanofibers (CNFs) was achieved using plasma polymerization of acrylic acid. Transmission electron microscopy (TEM) and spectroscopy techniques were used to assess the structural changes and type of chemical groups grafted on CNFs during plasma treatment. Electron energy loss spectroscopy ana…
