<div class="section abstract"><div class="htmlview paragraph">A physico-chemical model of a Cu-zeolite SCR/DPF-system involving NH₃ storage and SCR reactions as well as soot oxidation reactions with NO₂ has been developed and validated based on fundamental experimental investigations on synthetic gas test…
<div class="section abstract"><div class="htmlview paragraph">The Diesel Oxidation Catalyst (DOC) is an important technology for the removal of CO and hydrocarbons (HC) from the exhaust of diesel engines, as well as for generating exotherms for active regeneration, and for producing NO₂ used by downstream…
Abstract A review of published works in the field of catalyst synthesis and treatment with the use of non‐equilibrium plasma techniques has been composed. Non‐equilibrium plasmas, also called low temperature plasmas, are known for their high reactivity (high electron temperature), while keeping the overall gas tempera…
Single anatase TiO₂ nanowire is synthesized using the electrospinning technique with the sol-gel method and is suspended over a pre-processed 100 µm-wide TEM grid for further characterization. The diameters of the nanowires fall in the range of 250-400 nm. The transient electrothermal (TET) method is adopted to acquir…
Reactive magnesia cements have recently emerged as a potentially more sustainable and technically superior alternative to Portland cement as they set by absorbing carbon dioxide and as a result gain significant strength. This two-part publication investigates the application of reactive magnesia alone as the cement co…
We investigate the electrical and magnetic properties of low-energy H${}^{+}$-implanted ZnO single crystals with hydrogen concentrations up to $\ensuremath{\sim}$3 at% in the first 20-nm surface layer between 10 K and 300 K. All samples show clear ferromagnetic hysteresis loops at 300 K with a saturation magnetization…
Spider silk is an icon of supertough energy absorbing polymeric material which its macromolecular multiblock composition has been attributed to be responsible for such remarkable properties. As in spider silk, polyurethanes can be synthesized with two distinct block which can differ in nature, combining properties lik…
This study describes the use of the ionic liquid trimethylsulfonium bis(trifluorosulfonimide) [Me 3 S][TFSI] as an electrolyte for carbon-based supercapacitors at temperatures up to 80 °C. [Me 3 S][TFSI] is synthesized by a metathesis reaction, possesses a low melting point ( T m = 45.5 °C), and presents crystal plast…
We present a strategy to achieve heterogeneous seeded growth on nanoparticle (NP) surfaces and construct various Pt nanostructures (cage- and ring-like) by using selective etching as surface-free-energy-distribution modifier. Preprepared Au polyhedron NPs (octahedron, decahedron, nanorod, and nanoplate) are mixed with…
<div class="section abstract"><div class="htmlview paragraph">The high global warming potential of nitrous oxide (N₂O) led to its recent inclusion in the list of regulated pollutants under the emerging greenhouse gas regulations. While N₂O can be present in small quantities among the combustion products, i…
Abstract Controllable fabrication of compositionally graded Gd 0.1 Ce 0.9 O 2‐δ and Y 0.16 Zr 0.84 O 2‐δ electrolytes using co‐sputtering is demonstrated. Self‐supported membranes were lithographically fabricated to employ the new electrolytes into thin film solid oxide fuel cells. Devices integrating such electrolyte…
Single-phased white light emitters made of semiconductor bulk materials are most desirable for use in white light-emitting diodes (WLEDs) based on both photoluminescence and electroluminescence. Here we demonstrate Cd and/or Se substituted double-layer [Zn 2 S 2 (ha)] (ha = n -hexylamine) hybrid semiconductors emit br…
We describe a facile method to synthesize sterically stabilized monodisperse fluorescent poly(methyl methacrylate) (PMMA) colloids in the polar solvent mixture water/methanol with either a core-shell or a homogeneously cross-linked structure by dispersion polymerization. The particles were sterically stabilized by the…
Novel thermoplastic poly(thioether sulfone)s, poly(TCDSH/DVS) and poly(BSMD/VSTCD), with high refractive indices and high Abbe’s numbers have been developed using disulfanyltricyclo[5.2.1.0 2,6 ]decane (TCDSH) and bis(vinylsulfone)tricyclo[5.2.1.0 2,6 ]decane (VSTCD) based on tricyclo[5.2.1.0 2,6 ]decane moiety. TCDSH…
Stable colloidal suspensions of buckminsterfullerene (nC(60)) in aqueous environments can significantly affect the fate and transport of hydrophobic organic contaminants by serving as a contaminant carrier. In this study, we examined enhanced transport of 2,2',5,5'-polychlorinated biphenyl (PCB) in saturated sandy soi…
A water-soluble molecular transporter with a dendritic core-shell nanostructure has been prepared by a tandem coordination, ring-opening, hyperbranched polymerization process. Consisting of hydrophilic hyperbranched polyglycerol shell grafted from hydrophobic dendritic polyethylene core, the transporter has a molecula…
A high-yielding exfoliation of graphene at high concentrations in aqueous solutions is critical for both fundamental study and future applications. Herein, we demonstrate the formation of stable aqueous dispersions of pristine graphene by using the surfactant sodium taurodeoxycholate under tip sonication at concentrat…
The ground state geometry and electronic structure of various 4d transition metal (TM) atom (Y, Zr, Nb and Mo) decorated single wall carbon nanotubes (SWCNTs) are obtained using density functional theory and the projector augmented wave (PAW) method. We found a systematic change in the adsorption site of the transitio…
An important unsolved problem in materials science is prediction of the thermodynamic stability of organic crystals and their solubility from first principles. Solubility can be defined as the saturating concentration of a molecule within a liquid solvent, where the physical picture is of solvated molecules in equilib…
In this article, we review definition, origin, terminology, fundamental properties, design concepts and procedures, basic applications, modeling, and numerical simulation of metamaterials. It is shown that metamaterial origin can be easily understood by placing metamaterials in the more general context of artificial e…
