The present dissertation describes the atomic structures of two systems of ternary chalcogenide glasses with the composition Agx(GeSe3){1-x} and (GeTe){1-x}(Sb2Te3){x}. To be able to gain new insight especially in the structures on intermediate length scales, the method of anomalous x-ray scattering (AXS) in combinati…
Sodium monofluorophosphate, chemically known as Na2PO3F and from here on referred to as Na-MFP, has long been known as a surface applied corrosion inhibitor in the concrete industry. Over the past decade, Na-MFP has gained large interest as an inorganic self-healing agent, particularly on blast furnace slag cement (BF…
Rhodamine B (RhB) was utilized as a dye sensitizer for dye-sensitized solar cells (DSSCs) and its photovoltaic property was examined under the illumination of AM 1.5 G, 100 mWcm-2. DSSCs based on RhBexhibited typical photovoltaic properties with an open-circuit voltage (VOC) of 0.34 V, a short-circuit current (JSC) of…
Depuis plus d'un demi siècle, la transition de la phase métallique vers la phase isolante du dioxyde de Vanadium a captivé les physiciens du solide. Dans sa phase haute température, VO2 est métallique, avec une structure cristalline tetragonale rutile. Dans sa phase basse température, le matériau possède des propriété…
The aim of the present work is the development and implementation of new simulation possibilities for the CAST program package. Development included, among other things, the partial parallelization of the already existing force fields, extension of the treatment of electrostatic interactions and implementation of mole…
W artykule zaprezentowano rezultaty analiz chemicznych i metalograficznych czterech pieczęci ołowianych z Czermna (Grody Czerwieńskie). Zostały one wybite przez książąt ruskich i datowane są na XII–XIII w. Przedmioty te poddano obserwacji pod elektronowym mikroskopem skaningowym (SEM). Wśród analiz chemicznych należy…
本論文成功發展於室溫且水相環境中，使用單一金屬前驅物與檸檬酸一步合成超小氧化鐵奈米粒子。檸檬酸為天然的抗氧化劑且高生物相容性高與生物可降解，作為前驅物之過鐵酸鉀為強氧化劑且已被用於廢水處理。所合成之超小氧化鐵奈米粒子具有極低磁性且能夠良好方分散在水中，因此具有極低的r2遲緩速率(1.22 mM-1s-1)與r2/r1比(1.3)，此兩種性質滿足理想MRI-T1顯影劑的條件。令人驚奇的是，此粒子可以避開單核吞噬細胞系統，增加在體內的停留時間並成功顯影腦部血管，則可幫助判別腦部血栓。此外，T1-和T2-性質可以經由小鼠的腎臟MRI證實，可以幫助辨別其表層、髓質與生理功能。此新開發的超小氧化鐵奈米粒子可以由簡單的合成步驟製備，並具有低毒…
SARISTU (Smart Intelligent Aircraft Structures) is a level 2, large-scale integrating project which aims at achieving reductions in aircraft weight and operational costs, as well as an improvement in the flight profile specific aerodynamic performance. The project focuses on integration activities in three distinct te…
Part 1 of this work describes the development of accurate physically grounded force fields for intermolecular Cation-π interactions based on SAPT energy decomposition analysis. The presented results demonstrate the benefits of the used DFT-SAPT method to describe non-bonding interactions. First of all, this method is…
In oxidischen Heterostrukturen rufen Neuordnung von Ladung und Spin eine Vielzahl von unerwarteten physikalischen Eigenschaften hervor. Die Moglichkeit, Leitfahigkeit, Magnetismus oder auch Hochtemperatur-Supraleitung zu kontrollieren, machen diese kunstlich hergestellten Materialien vor allem in Hinblick auf eine zuk…

Asphalt concrete is one of the most common types of pavement surface materials used in the world. It is a porous material made at very high temperatures (~180 °C) that consists of a mixture of asphalt binder (bitumen), aggregate particles and air voids. After some years of use, the stiffness of asphalt concrete increa…
As-cast Mg-4Zn-0.5Zr, Mg-4Zn-2Gd-0.5Zr and Mg-4Zn-2Nd-0.5Zr alloys were investigated by in situ synchrotron radiation diffraction during hot compression at 350 °C using the facilities of P07 beamline of Petra III at Deutsches Elektronen Synchrotron (DESY), Hamburg, Germany. The specimens were heated at a rate of 100 K…

In this study, we grew TiO2 nanorods on TiO2-film buffered FTO substrate using modified chemical bathdeposition (M-CBD). The TiO2 buffer layer was grown by spin coating method with different RPM (revolutions per minute) values and deposition cycles. We investigated the effects of the RPM values and the deposition cycl…
The present paper describes a new in-situ synthesis route of MMCs leading to enhanced mechanical properties and to nanosized reinforcement without handling of nanosized particles.
In order to solve the preparation of graphene oxide( GOs) and its dispersion in polymer composites,GOs were prepared by ball milling method,the GOs / PF in situ resin was prepared by in-situ polymerization,and the GOs /PF composites were prepared by rolling and molding process. Effects of GOs contents on the mechanica…
There has been a great advance in the grinding process by the development of dressing, lubri-refrigeration and other methods. Nevertheless, all of these advances were gained only for continuous cutting; in other words, the ground workpiece profile remains unchanged. Hence, it becomes necessary to study grinding proces…
XANES and some relevant EXAFS spectra have been recorded at the XAFS beamline on a set of PTFE filters consisting of deposit of urban dust (from the Emilia Romagna region, Italy). Several metals K-edges were recorded (Fe, Ni and Zn), as planned, but several others relatively important metals were not acquired. Overall…
