In this paper, new azobenzene imide derivatives with different substituent groups were designed and synthesized. Their gelation behaviors in 21 solvents were tested as novel low-molecular-mass organic gelators. It was shown that the alkyl substituent chains and headgroups of azobenzene residues in gelators played a cr…
For safe and fast refueling hydrogen to fuel cell vehicles (FCVs) at hydrogen refueling stations (HRSs), a refueling protocol is under discussion at SAE J2601 to be a global standard. In order to realize such a standard, we have to estimate the relation between gas temperature and pressure during a refueling and for a…
In this study, a DOC catalyst was experimentally studied in an engine test cell with a2010 Cummins 6.7L ISB diesel and a production aftertreatment system. The test matrix consisted of steady state, active regeneration with in-cylinder fuel dosing and transient conditions. Conversion efficiencies of total hydrocarbon (…
PURPOSE: To design, fabricate, characterize, and in vivo assay clinically viable magnetic particles for MRI-based cell tracking. METHODS: Poly(lactide-co-glycolide) (PLGA) encapsulated magnetic nano and microparticles were fabricated. Multiple biologically relevant experiments were performed to assess cell viability,…
Electrochemical processes associated with changes in structure, connectivity or composition typically proceed via new phase nucleation with subsequent growth of nuclei. Understanding and controlling reactions requires the elucidation and control of nucleation mechanisms. However, factors controlling nucleation kinetic…
A new family of binuclear lanthanide compounds of general formula [Ln(2,4-DClBA) 3 phen] 2 (Ln(III) = Nd ( 1 ), Sm ( 2 ), Dy ( 3 ), Yb ( 4 ); 2,4-DClBA = 2,4-dichlorobenzoate; phen = 1,10-phenanthroline) have been synthesized and characterized by elemental analysis, molar conductance, infrared spectroscopy, ultraviole…
Abstract We report a method to create a self‐cleaning, transparent surface on poly(methyl methacrylate) (PMMA) using a dry etching with CF4 plasma and a subsequent hydrolysis process with water immersion. During the CF4 plasma treatment, nanoscale pillar structures were formed and its aspect ratio tended to increase.…
Oxygen‐deficient BaTiO 3‐δ nanoceramics were prepared by spark plasma sintering. Partially reduced raw nanopowders led to unusual dielectric properties. A short postsintering treatment was performed to reach a high ε r /tan δ, which makes them attractive for industrial applications such as low‐frequency capacitors. Su…
Graphene nanowiggles (GNWs) are one-dimensional wiggle edged graphene nanoribbons (GNRs) that have been synthesized using an atomically precise bottom-up approach. They are known to possess superior thermoelectric properties compared to straight GNRs. Here, first-principles density functional theory calculations estab…
Abstract Epoxidized soybean oil (ESO)/diglycidyl ether of bisphenol A (DGEBA) in various blend ratios (i.e. 100/0, 90/10, 80/20, 70/30, 60/40, 50/50) was thermally cured using methylhexahydrophthalic anhydride in the presence of 2‐ethyl‐4‐methylimidazole catalyst. The tensile properties and fracture toughness of the E…
BACKGROUND: In our previous study, we successfully developed 3-D scaffolds prepared from silk fibroin (SF), silk fibroin/collagen (SF/C) and silk fibroin/gelatin (SF/G) using a freeze drying technique. The blended construct showed superior mechanical properties to silk fibroin construct. In addition, collagen and gela…
Nonpolar m-plane ZnO films are deposited on GaN (0002) with a 10 nm Al2O3 interlayer by atomic layer deposition. The growth direction of the ZnO films directly on GaN (0002) is [707¯4] (perpendicular to (101¯1) plane), whereas with the Al2O3 interlayer it changes into [101¯0]. With the Al2O3 interlayer, the m-plane Zn…
NH₃/urea SCR is a very effective and widely used technology for the abatement of NOx from diesel exhaust. The SCR mechanism is well understood and the catalyst behavior can be predicted by mathematical models - as long as operation above the temperature limit for AdBlue® injection is considered. The behavior below thi…
In this work we present, for the first time to our knowledge, laser emission under wavelength selective laser-pulsed pumping in Nd(3+)-doped TeO(2)-ZnO-ZnF(2) bulk glass for two different Nd(3+) concentrations. The fluorescence properties of Nd(3+) ions in this matrix which include, Judd-Ofelt calculation, stimulated…
Meeting the upcoming NOx emissions standards is a major challenge for the lean-burn engines, thus requiring a highly efficient exhaust gas aftertreatment. Currently, the Selective Catalytic Reduction (SCR) appears to be the most promising technology, especially when operated with two kinds of reductants: ammonia (gene…
Abstract This review of metal‐based nanoparticles focuses on factors influencing their distribution into the nervous system, evidence they enter brain parenchyma, and nervous system responses. Gold is emphasized as a model metal‐based nanoparticle and for risk assessment in the companion review. The anatomy and physio…
Die direkte Oxidation eines Triamidoamin-Uran(III)-Komplexes mit Trimethyl-N-oxid liefert einen terminalen Uran(V)-Mono(oxo)komplex, der das erste gesicherte Beispiel eines Uran(V)-Einzelmolekülmagnets ist. Dieser monometallische Komplex zeigt eindeutig, dass ein starkes axiales und somit anisotropes Ligandenfeld die…
Nanoparticles target tumor cells by pH-controlled means. Nanoparticles carry three synergistic delivery functions: 1) tumor tissue targeting by the EPR effect; 2) tumor cell targeting by pHLIP-mediated membrane-localization; and 3) tumor cell uptake by adsorptive-mediated endocytosis.
Nickel ferrite nanocrystals were prepared from an aqueous solution containing metal nitrates and various concentrations of poly(vinylpyrrolidone) followed by calcination temperature. X-ray diffraction (XRD) analysis was performed to determine the degree of crystallinity of the ferrite nanoparticles. By transmission el…
The analysis of the air gap between fire-protective clothing and the skin plays a crucial role in evaluating the protective performance of the clothing. However, the more accurate the analysis of the air gap, the more complex the air-gap model. This article introduces a novel air-gap model that stands halfway in terms…
