Abstract Methyl‐substituierte carbocyclische Aromaten der Benzol‐, Diphenyl‐, Terphenyl‐, Stilben‐, 1,4‐Diphenylbutadien‐, Tolan‐, 1,4‐Diphenylbutadiin‐, Naphtalin‐, Anthracen‐und Phenanthren‐Reihe werden mit Anilen aromatischer Aldehyde in Dimethylformamid Gegenwart von Kaliumhydroxid oder Kalium‐ t ‐butylat zu Styryl‐Derivaten umgesetzt.
Abstract Covalently functionalizing mechanical exfoliated mono‐ and bilayer graphenides with λ‐iodanes led to the discovery that monolayers supported on a SiO 2 substrate are considerably more reactive than bilayers as demonstrated by statistical Raman spectroscopy/microscopy. Supported DFT calculations we show ditopic addend binding leads much stable products corresponding monotopic reactions result of lower lattice strain products. The chemical nature (graphene versus ) plays crucial role.

Die kovalente Funktionalisierung von mechanisch exfoliertem Graphenid-Monolagen und -Bilagen auf SiO2-Wafern mit λ-Iodanen anschließende Raman-spektroskopische/-mikroskopische Charakterisierung haben gezeigt, dass Graphen-Monolagen bedeutend reaktiver sind als entsprechende Bilagen. Mittels unterstützender Dichtefunktionalrechnungen konnten wir zeigen, die ditope Addendenbindung zu sehr viel stabileren Produkten führt monotope Reaktion. Dies kann durch geringere Gitterspannung der...
Der erfolgreiche Einsatz von Magnesium im Metallbau wird durch den und die Entwicklung Methoden zum Oberflächenschutz und, wenn nötig, einer elektrisch isolierenden Schicht zwischen anderen metallischen Werkstoffen, gefördert [1]. Geeignete Materialien stellen dabei beispielsweise polymere Lacke dar. Diese erfordern jedoch einen ausreichend korrosionsschützenden Untergrund, der bislang wesentlichen in Form umweltgefährdenden Chromatschicht auf aufgebracht wird. Im Falle Verletzungen...
With regards to the decarbonization of transportation sector in near future, importance proton exchange membrane (PEM) fuel cells is shifting more and from light-duty vehicles heavy-duty vehicles, as well an application for maritime aviation applications. this change field application, requirements cell system need be adjusted towards increased efficiency lifetime. 1 Especially targeted durability 25,000 h requires a detailed understanding degradation processes within stack able minimize...

For understanding of existing battery systems such as lithium-ion batteries and for the development future systems, advanced numerical simulation tools are important. One beneficial aspect computational methods is that they can provide insight into physical chemical aspects, which sometimes cannot be probed by experimental methods. Accuracy reliability key issues simulations depend on appropriate models, boundary conditions, accurately determined physico-chemical parameters 1 . ion-transport...
Within the past years, proton exchange membrane (PEM) fuel cells have become more and attractive due to their potential for transition towards an environmentally friendly hydrogen economy. Especially by reducing platinum catalyst loading, significant system cost reductions could be achieved, but low Pt loadings still lead unassigned voltage losses during operation. [1,2] In order overcome those losses, well-designed layers with optimized ionomer content distribution are indispensable. The...
While nowadays lithium ion batteries are used in a wide range of consumer electronic devices and full electric cars, they still suffer from limited energy density, required for larger driving ranges or long-lasting mobile phone batteries. One way to improve the density is increase electrode loading, i.e., thickness anode cathode coating layers. By increasing layer thickness, transport ways prolonged rate limitations can occur if drawn applied current too large, depending on morphology...

The claim that it is always good to be reasonable can understood mean either being better than unreasonable all things considered or in at least one respect. This paper tries evaluate both claims and argues for the second, weaker thesis while dismissing first. To do this, two distinct ideas contained our every-day understanding of reasonability are distinguished formulated more precisely. It then argued that, regardless which idea we take fundamental, respect, though not considered.

Every theory of rationality worth taking seriously implies that it is in some way irrational to accept contradictions. In this essay, the author examines how exactly basic idea should be spelled out. He argues for two claims. First, not practically a contradiction sense causing oneself have contradictory beliefs. Second, moreover theoretically having beliefs, if contradictoriness relevant beliefs inaccessible person. The set accessible person only possesses general cognitive capacities...
