<div class="section abstract"><div class="htmlview paragraph">In order to comply with the introduction of new emission limits, motorcycles have been equipped with electronic injection systems and three-way catalytic converters for emissions abatement. However, these converters produce unwanted reactions, s…
The most anti-aromatic 16π porphyrin, an octaethylporphyrin (OEP) zinc(II) complex with no substituents at the meso-positions was generated as a highly unstable species from the reaction of the corresponding 18π porphyrin using strong oxidants such as AgSbF 6 / I 2 or SbF 5 . The porphyrin showed a significant blue-sh…
Single-bubble sonoluminescence (SBSL) spectra from aqueous sulfuric acid solutions containing dissolved neon show widely varying emission despite being similar in chemical composition. From a 65 wt % solution, emission from hydroxyl radicals is observed, with the rovibronic progression being well-described by a single…
The wet strength of handsheets subjected to dipping treatment by solutions such as glyoxal with Zn(NO 3 ) 2 as a catalyst, chitosan, and the crosslinking system of glyoxal and chitosan is studied in this paper. The crosslinking system achieved better wet strength performance than glyoxal or chitosan alone and slightly…
Poly(lactic acid) (PLA)/palygorskite (PA) nanocomposites were fabricated through melt blending. The significant finding by Fourier transformed infrared spectra and X‐ray photoelectron spectroscopy was that the hydrogen bonding interaction between PA surface and PLA matrix. Due to the hydrogen bonding interaction, the…
As at nano/micro-scale van der Waals forces often dominate various other types of forces, the accurate adhesion characterization of graphene (Gr) is essential to its processing, manipulation, and possible integration into integrated circuits and other nano/micro-scale devices. Since 2010, the reported (experimental) a…
Absorption zeigt Absorption an: Die Oberflächenplasmonenresonanzbande von tetrahexaedrischen, oktaedrischen und kubischen Au/Pd-Kern/Schale-Nanokristallen wird bei Absorption von Wasserstoff in die Pd-Schale stark rotverschoben. Diese reversible Spektralverschiebung könnte für die Entwicklung von Sensoren für Wasserst…
Abstract We fabricated flexible n ‐type carbon nanotube thin‐film transistors on a plastic film by a simple transfer process and a solution‐based chemical doping technique with polyethyleneimine (PEI). There exists an optimal PEI concentration, which is determined by doping level and charge accumulation in the PEI lay…
The structure differences of magnetoelectric (ME) laminates for passive and active mode sensors are discussed. The Fourier coefficient A1 calculated from the data of αME-Hdc indicates that N = 1 (where N is the number of Metglas layers) should be the optimum structure for the active mode. Experimental investigations o…
Organic-inorganic hybrid materials prepared by sol-gel approach have attracted a great deal of attention in material science. Organic polymeric part of the composite provides mechanical and chemical stability whereas the inorganic part supports the ion-exchange behaviour and thermal stability and also increases the el…
Coordination exchange processes tend to dominate the solution state behaviour of lanthanide chelates and generally prohibit the study of small conformational changes. In this article we take advantage of coordinatively rigid Eu(3+) chelates to examine the small conformational changes that occur in these chelates as wa…
Acellular biological tissues, including bovine pericardium (BP), have been proposed as biomaterial for tissue engineering. BP is usually modified chemically to improve mechanical and biological properties using glutaraldehyde, the standard reagent for preservation of fresh bioprosthetic materials. Glutaraldehyde-fixed…
A comparative study of UV‐irradiation‐induced refractive index modulation in two analogous monodomain nematic side‐chain liquid‐crystalline elastomer materials is conveyed. In one of them, mesogenic azobenzene derivatives are incorporated as pendant co‐monomers, and in the other as crosslinking units. The dependence o…
Using molecular dynamics simulations, we study the properties of liquid state polymer-nanoparticle composites confined between two parallel substrates, with an attractive polymer-substrate interaction. Polymers are in the semidilute regime at concentrations far above the overlap point, and nanoparticles are in good so…
Abstract Crystalline quality and optical properties of gallium oxide films grown on SiO 2 substrates by RF magnetron sputtering were studied. After the post annealing, it could be confirmed growth of gallium oxide (Ga 2 O 3 ) film changed in a β ‐Ga 2 O 3 film. Estimated optical energy gap of as‐grown and post anneale…
The N-representability problem for noncollinear spin-polarized densities was left open in the pioneering work of von Barth and Hedin [J. Phys. C 5, 1629 (1972)] setting up the Kohn-Sham density-functional theory for magnetic compounds. In this Letter, we demonstrate that, contrarily to the nonpolarized case, the sets…
It is of great importance to construct a stable superhydrophobic surface with low sliding angle (SA) for various applications. We used hydrophobic carbon nanotubes (CNTs) to construct the superhydrophobic hierarchical architecture of CNTs on silicon micropillar array (CNTs/Si-μp), which have a large contact angle of 1…
In the expanding field of plasmonics, accurate control of the degree of plasmon localization is of crucial importance for tailoring optical properties at the nanoscale. In this paper, the degree of plasmon localization is directly probed by recording the momentum transfer dependence (i.e. the dispersion) of plasmon re…
In this review, we recollect and discuss the most relevant advancement in crystallographic aspects of alkali nitrates compounds published since 1975, the year of publication of the last review by Rao et al. about some topics discussed here. This review is focused in five nitrate compounds of the first periodic table c…
A new highly soluble platinum porphyrin derivative 10 with suppressed photobleaching is prepared on a multigram scale from inexpensive starting materials. 10 possesses intense absorption bands at λ = 463 nm (log ε = 5.39) and 633 nm (log ε = 5.20) with near-IR emission at 755 nm. Efficient NIR phosphorescence (PLQY =…
