The high temperatures required to operate solid oxide fuel cells (SOFCs) allow for internal reforming of hydrocarbon fuels over a Ni-based anode. With their capability of being fuel flexible, SOFCs have operated under a wide range of fuels including diesel as examined in this study. But in order to reduce high possibi…
Abstract Reaction of iron(II) thiocyanate with 4,4‐bipyridine (bipy) in methanol leads to the formation of three new solvates of different composition depending on the reaction conditions: At room temperature two new ligand‐rich 1:2 (1:2 = ratio between metal and N‐donor ligand) polymorphic forms [Fe(NCS)2(bipy)2·2MeO…
Festgeklebt: Ein heterotropes Konjugat aus Actin und Myosin – Actomysin – wird durch einen wasserlöslichen „molekularen Klebstoff“, ein Dendrimer mit neun Guanidinium-Resten, stabilisiert (siehe Bild; ATP=Adenosintriphosphat, ADP=Adenosindiphosphat). Während das Dendrimer erster Generation die ATP-getriebene Gleitbewe…
Behütete Aufzucht: Eine neue Methode für die Synthese von einheitlichen, kleinen, trägerfixierten Metallnanopartikeln durch Atomlagenabscheidung (ALD) wird beschrieben. Der ALD-Prozess beruht auf der simultanen Abscheidung von geschützten Metallnanopartikeln und neuen Trägerschichten bei niedrigen Temperaturen. Anschl…
In recent years, a number of disruptive dielectric failures of unknown cause have occurred on grading capacitors installed on circuit-breakers switching shunt reactors. In an attempt to clarify the origin of these failures, the electrical stresses to which the grading capacitors are subjected in service have been stud…
The green algal genus Basicladia W. E. Hoffman & Tilden suggested for synonymy in Cladophora Kütz. by van den Hoek is reconfirmed as a genus based on the distinct basal system and the primarily epizoic habit associated with freshwater turtles. Previously assigned to Cladophora sect. Basicladia (W. E. Hoffmann & Tilden…
Stress and temperature dependence of the structure of the X-phase in Ni2MnGa has been investigated by neutron diffraction measurements to clarify the structural relationship among the parent (P-), intermediate (I-), martensite (M-) and X-phases. The satellite position and intensity of the X-phase differ from those of…
The solubilities of nizatidine in water, methanol, ethanol, acetone, and ethyl acetate were determined in the temperature range from (273.15 to 343.15) K by a static analytical method. The concentrations of nizatidine in saturated solution were analyzed by reverse-phase high-performance liquid chromatography. An empir…
We show that vertically aligned nanorod arrays composed of copper phthalocyanine (CuPc) molecules can be grown on various substrates using the oblique angle deposition technique in high vacuum. High-density nanorod arrays with diameters of 20-70 nm and spacing of 10-100 nm have been achieved with either stationary or…
We report the investigation of glass-forming salol upon different courses of the temperature changes from liquid to glass state and back using FT-IR spectroscopy measurements in the wide spectral and temperature ranges. The formation of the ordered clusters in supercooled liquid salol has been observed at 250 K. When…
Die dritte Dimension kommt bei der Synthese zweidimensionaler Kristalle mit begrenzter Größe zur Hilfe. Entsprechende graphenartige Einzelschichten von Metall(IV)-Chalkogeniden werden durch Stapelung zu Nanoobjekten stabilisiert, die in ihrer Form an Münzrollen erinnern. Die Spannung infolge der Gitterfehlanpassung zw…
The generalized S-transform was improved as a method to determine the refractive index of a dielectric film continuously by using the transmittance spectrum, and the applicability of the method was demonstrated on mica. The result determined from the generalized S-transform method was compared with the results determi…
The new complex silver(II) oxide AgSO4 was synthesized by a methathetic reaction of Ag(SbF6)2 and K2SO4 in anhydrous HF at −80 °C or by the reaction of AgF2 with H2SO4 at −35 °C. The magnetic moments of the rectangular planar coordinated Ag2+ ions in AgSO4 are antiferromagnetically coupled to the chains through the O–…
Bis[2-(2-hydroxy-3-methoxybenzylideneamino)phenolato-kappaO]dimethylsilicon, C(30)H(30)N(2)O(6)Si, (II), was isolated from the reaction of 2-(2-hydroxy-3-methoxybenzylideneamino)phenol, (I), with dichlorodimethylsilane at 339 K. It consists of two ligand molecules and the Me(2)Si unit forming a dialkoxydimethylsilane…
We have developed a pervious Raman extracavity laser intensity equation by taking into account the nonlinear Kerr effect and group velocity dispersion and by considering the chalcogenide glass as an active material for its high Raman gain. The propagation of fundamental dark solitons is simulated by the combination of…
Protein-coated microcrystals can be generated by co-precipitation of protein and a water-soluble crystalline carrier by addition to excess water miscible organic solvent. We have investigated this novel process for its utility in the concentration and partial purification of a recombinant protein exported into the cul…
We establish an analytical model for a thermal inclusion in bi-layer materials. The inclusion is considered as either an elliptic filler of finite thermal conductivity or a crack of ideal thermal insulation. Unlike most existing studies, this article focuses on bonded media of finite size in both their height and the…
Large single-grain bulk superconductor has significant potential for industrial applications because it can trap high magnetic fields. However, when the superconductor endured the magnetization processes, the enormous mechanical stresses are imposed on the bulk, which often lead to cracking. In this paper, the magneti…
The large aspect ratio of interfacial area per unit volume at CNT/matrix interfaces may significantly influence the macroscopic behavior of CNT-reinforced composites. The property of interfaces is governed by the cohesive law, which is determined from both van der Waals forces and chemical covalent bonds. This nonline…
