Im Rahmen von Auswirkungsbetrachtungen, wie sie bei Sicherheitsberichten oder Risikoanalysen erforderlich sind, sind oft Szenarien mit einer Lachenverdunstung von brennbaren und/oder toxischen Flüssigkeiten zu untersuchen. Wesentliche Einflussgrössen für die Konzentrationsverteilung in der Umgebung sind der Verdunstun…

Organic photovoltaic (OPVs) cells are viewed as one of the most promising candidates for low cost solar cells because of the possibility of a simple and cheap production on flexible and large area substrates.The best performing solar cells often contain a poly(3,4ethylenedioxythiophene) : polystyrenesulfonate (PEDOT:P…
Over the last decade, polymer micelles attracted an increasing interest in drug pharmaceutical research because they could be used as efficient drug delivery systems. Micelles of amphiphilic block copolymers are supramolecular core-shell type assemblies of tens of nanometers in diameter. In principle, the micelles cor…
It has previously been determined that different acids have different effects on molecular weight, and that methanol greatly increases degradation, while ethanol, though very similar in structure and properties, has no effect. This leads to the study that is the focus of this thesis. Our goal is to determine if the re…
Two novel intercalation composites (Cu2+/GO and Zn2+/GO, GO: graphite oxide) were prepared by coordinate chemistry, and characterized by XRD, SEM, EDS, IR and XPS. The results indicated that the two composites all have the lamellar structure with a wider spacing distance than that of graphite oxide. The metal ions are…
α-Fe2O3polyhedrons have been successfully synthesized via a one-pot hydrothermal process. The average diameter of the synthesized α-Fe2O3 polyhedrons is about 0.8 μm. The structure and morphology of α-Fe2O3 polyhedrons were characterized by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniqu…
A series of TiO2 thin films with and without Ce3+ doping were successfully obtained on microscope glass slides by sol-gel method. The photocatalytic activities of the pure TiO2 and Ce3+-doped TiO2 thin films were evaluated by the degradation of rhodamine B solution. The effects of both Ce3+ contents and annealing temp…
In this paper, Sm0.5-xGdxSr0.5CoO3-δ (SGSC, x=0 and 0.2) powders were prepared using the solid-state reaction method. Their structure was identified by XRD. All powders formed the perovskite phase when calcined at 1100°C for 5 h. Sm0.3Gd0.2Sr0.5CoO3-δ/Gd0.1Ce0.9O1.95 slurrieswere screen printed onto both surfaces of G…
The inhibition effect of N,N-diethylammonium O,O'-di(4-Methylpheny)dithiophosphate (NOPP, [NH2Et2][(4-MeC6H4O)2PS2])against the corrosion of carbon steel in HCl solution was studied by weight loss measurements, electrochemical measurements, AFM and SEM techniques. The studies of weight loss measurements indicate that…
The present investigation aims at elucidating the photoluminescence (PL) behaviour of Tb3+ doped SiO2–M2O3 (M=Al, Ga)–LiF–CaF2 optical glasses. The absorption spectra of these glasses have revealed the absorption bands due to 7F6 → (5L8, 5G3, 5L9, 5G4, 5D2, 5G5), 5L10, (5G6, 5D3) and 5D4 transitions. The Tb3+ excitati…
TiO2 and different contents Fe3+-doped TiO2 thin films were successfully obtained on microscope glass slides by Sol-Gel method. Then the photocatalytic activities of the samples were evaluated by the degradation of Rhodamine B dye solution. The effects of both annealing temperatures and Fe3+ contents on the photocatal…
LiNi0.75Co0.15Mn0.1O2 was prepared by solid state reaction and its crystal structure was studied by Rietveld Refinement. The result shows that the oxygen octahedron surrounding transition elements in LiNi0.75Co0.15Mn0.1O2 is distorted. The lengths of twelve edges of the octahedron are different. The lengths of twelve…
Using tetrabutyl titanate as source, ethanol as solvent, acetic acid as complexing agent, synthesis of titanium dioxide sol was achieved by sol-gel method. A transparent sol aging in air 30min, titanium dioxide films were prepared by using spin coating method. Rhodamine B degradation by TiO2 photocatalysis was investi…
The core-shell structure’s synthesis process by one-step hydrothermal method has remarkable peculiarities, such as simple procedures and short production cycles. In order to get the precursor with the core-shell structure, it’s important to study the technological parameters. In this paper, the pH value, the concentra…
