Die Cloridionen in Bi12Rh3Cl2 werden trotz ihrer offenbar festen Bindung im Kristallgerüst unter milden Bedingungen quantitativ gegen Bismutatome ersetzt, und es entsteht die metastabile intermetallische Phase Bi14Rh3. M. Ruck und Mitarbeiter zeigen in ihrer Zuschrift auf S. 3319 ff., dass dieser Transport von Ionen d…
Sondaj endüstrisinde kullanılan çelik borular servis şartlarında farklı yükler altında kullanılmaktadırlar. Bu çalışmada; N80-N80 aynı cins ve N80-42CrMo4, N80-S355J2 farklı cins çelik borular sürtünme kaynak yöntemi ile birleştirilmiştir. Birleştirmelerin yorulma davranışları araştırılarak, bulgular sertlik değerleri…
A sessile drop can elastically deform a substrate by the action of capillary forces. The typical size of the deformation is given by the ratio of surface tension and the elastic modulus, !/E, which can reach up to 10-100 microns for soft elastomers. In this report we theoretically show that the contact angles of drops…
Bu çalışmada seramik sağlık gereçleri bünyelerinde, kimyasal kompozisyonla birlikte camsı faz viskozitesinin değişimi incelenmiştir. Ayrıca, bu değişimin sinterleme sıcaklıkları üzerine etkisi araştırılmıştır. Seramik bünyedeki, müllit, kuvars ve camsı faz miktarı eğimler oranı yöntemi kullanılarak sırasıyla %18,8, %2…
Bu çalışmada, sarıçam (Pinus sylvestris L.) odun talaşı biyokütle kaynağı olarak değerlendirilmiş, sabit yataklı reaktörde, katalizörlü ve katalizörsüz (termal) pirolizi gerçekleştirilmiştir. Deneylerde piroliz ürünlerinin verimleri üzerine sıcaklık ve katalizör tipi gibi parametrelerin etkisi araştırılmıştır. 0,850-1…
Resumen-Películas delgadas de Dióxido de Titanio (TiO 2 ) fueron crecidas usando deposición física de vapor asistida por plasma (DFVAP) en un sistema de arco catódico a partir de un blanco de Ti.Para la producción de las películas, dentro de la cámara de reacción se ubicaron dos electrodos enfrentados (blanco y sustra…
This thesis studies the limitations of density functional theory. These limits are explored in the context of a traditional implementation using a plane waves basis set. First, we investigate the limit of the size of the systems that can be treated. Cutting edge methods that assess these limitations are then used to s…
We present a new Bayesian methodology to learn the unknown material density of a given sample by inverting its two-dimensional images that are taken with a Scanning Electron Microscope. An image results from a sequence of projections of the convolution of the density function with the unknown microscopy correction fun…
In late August 2012, liquid crystal scientists from around the globe gathered in the historic city of Mainz for the 24th International Liquid Crystal Conference (ILCC 2012). The meeting was attende...
In this thesis the influence of prestrain on anisotropic ductility and fracture toughness has been evaluated for API grade X100 line pipe steel. A omprehensive experimental investigation of microstructure, mechanical properties and fracture mechanisms has been carried out. A phenomenological model combining isotropic…
The slow flow of amorphous solids exhibits striking heterogeneities: swift localised particle rearrangements take place in the midst of a more or less homogeneously deforming medium. Recently, experimental as well as numerical work has revealed spatial correlations between these flow heterogeneities. Here, we use mole…
Ferromagnetic SrRuO3 thin films are deposited on the ab-surface of single crystals of the spin-triplet superconductor Sr2RuO4 as substrates using pulsed laser deposition. The films are under a severe in-plane compressive strain. Nevertheless, the films exhibit ferromagnetic order with the easy axis along the c-directi…
We consider a variational anti-plane lattice model and demonstrate that at zero temperature, there exist locally stable states containing screw dislocations, under conditions on the distance between the dislocations and on the distance between dislocations and the boundary of the crystal. In proving our results, we in…
The catalytic activities of the atomic Y-, Ru-, At-, In-, Pd-, Ag-, Pt-, and Os- ions have been investigated theoretically using the atomic Au- ion as the benchmark for the selective partial oxidation of methane to methanol without CO2 emission. Dispersion-corrected density-functional theory has been used for the inve…
This report summarizes the results of the extraction, scrub, and strip testing for the September 2013 sampling of the Next Generation Solvent (NGS) Blended solvent from the Modular Caustic Side-Solvent Extraction Unit (MCU) Solvent Hold Tank. MCU is in the process of transitioning from the BOBCalixC6 solvent to the NG…
Two types of emission under a single excitation wavelength are found for a polynuclear SmIII polyamidoamine-based dendrimer. S. V. Eliseeva, S. Petoud et al. show in their Communication on page 2927 ff. that it emits in the visible and in the near-infrared ranges. The dendrimer proved to be non-cytotoxic, able to be t…
There is a scene in the film “Spider-Man 2” where Spider-Man prevents a train full of people from crashing by holding it back with about 10 sets of spider silk ropes each less than half an inch thick. It turns out the scene isn’t just fantasy. “We calculated roughly how thick the fibers were, how many of them he had a…
We extend the physics of graphene to three dimensional systems by showing that Dirac points can exist on the Fermi surface of realistic materials in three dimensions. Many of the exotic electronic properties of graphene can be ascribed to the pseudorelativistic behavior of its charge carriers due to two dimensional Di…
The degradation of chemicals present in wastes by heterogeneous photocatalysis is an important issue and its study is a constantly growing field. An increasing number of papers deal with TiO2 (titania) as one of the most appropriate semiconductor materials to be employed as a photocatalyst, due to its high activity in…
Chemoradiation-resistant cancer cells and unresectable micro-tumors limit treatment efficacy and lead to high nonspecific toxicity or recurrence in head and neck cancers. We show the cancer cell-specific, on-demand enhancement of the chemo- and chemoradiation therapy with mechanical intracellular impact of plasmonic n…
