The manufacture of sintered glasses and glass-ceramics, glass Matrix composites and glass-bounded ceramics or pastes is often affected by gas bubble formation. Against this background, we studied sintering and foaming of barium silicate glass powders used as SOFC sealants using different powder milling scenarios. Sint…
On the very outset of this dissertation, I would like to extend immeasurable appreciation and deepest gratitude towards all amazing people who have helped
There is tremendous pressure to innovate in the automotive industry nowadays and the technological requirements are becoming increasingly complex. The materials for sealing elements have special requirements, especially considering the conditions of operation of such equipment assuming a long production cycle without…
The rational design of Transition Metal Substituted Polyoxometalates (TMSPs) structures is one of the biggest challenges of synthetic chemists working in the field. Even though it is known that certain factors such as the pH of the reaction or ratio of starting materials can determine the structure of the most commonl…
The transformation of para-aminothiophenol (PATP) to dimercaptoazobenzene (DMAB) is widely believed to be due to the emission of hot electrons from the plasmonic nanostructures,1 which are generated during the decay of the surface plasmons (LSPPs). Our aim here is to separate the catalytic activity of plasmonic nanost…
Introduction: Within the field of peripheral nerve regeneration, there is a need for efficient alternatives to nerve autografts in cases of severe nerve damage. A promising option is the use of decellularized peripheral nerve allografts (DPNAs). These DPNAs provide a natural nerve architecture without the risk of immu…
Um das Risswachstum in Glasern zu untersuchen, sind in einer Glovebox 185 Risse ausgehen von Vickers-Eindrucken in Kalk-Natron-Glas initiiert und gewachsen. Die direkte Beobachtung des unterkritischen Risswachstums erfolgte mit einer Hochgeschwindigkeitskamera. Die Ergebnisse zeigen, dass die statistische Auswertung v…
This research presents the results of a study comparing the hardware and software of four commercially available brands of three-dimensional (3D) body scanners. Fifty-five men and women over age 18 had baseline anthropometric measurements taken by flexible tape measure, air displacement plethysmography (ADP), and dual…
This work addresses efficiency improvements of solar cells by manipulating the spectrum of sunlight to bettermatch the range of efficient current generation. The intrinsic transmission losses in crystalline silicon can effectivelybe reduced using photon upconversion in erbium ions in which low energy photons are conve…

Industrial systems comprehending reduced losses components are always more and more requested: the Standards push towards the improvement of the efficiency, and this forces to find new solutions to fulfill the constraints. For laminated steels appropriate methods to measure or estimate the iron losses are applied: Eps…
Durch den selektiven Transport biologisch relevanter Substanzen in Krebs(stamm)zellen können Nebenwirkungen reduziert und die Effizienz von Therapien erhöht werden. Mesoporöse Silikananopartikel (MSN) sind aufgrund ihrer Eigenschaften eine ideale Plattform für die Entwicklung solcher partikulären Systeme. Durch Variat…
Das hier prsentierte Projekt beschftigt sich mit biomimetischen Katalysatoren fr die Sauerstoff-und Wasserstoffperoxidreduktion und deren Elektrokatalyse. Die biomimetischen Peroxidasen besitzen einen Porphyrinkomplex als katalytisch aktives Zentrum und sind entweder von natrlichen Hmproteinen abgeleitet oder chemisch…

以NiCrAlY为金属黏结层材料、以Al2O3和ZrO2为陶瓷层材料，采用等离子喷涂技术在304不锈钢表面制备了3种热障涂层，通过扫描电子显微镜（SEM）和X射线衍射仪（XRD）分别对涂层的微观形貌和晶相进行了表征，并研究了涂层的抗高温氧化性能和抗热震性能。结果表明：NiCrAlY/Al2O3/ZrO2复合结构热障涂层表面无孔洞和裂纹等缺陷，高温氧化后该涂层主要包括Mg2Zr5O12和（Fe，Mg）（Cr，Fe）2O4两种晶相；由于Al2O3的阻氧作用，NiCrAlY/Al2O3/ZrO2涂层具有最佳的抗高温氧化性能；NiCrAlY/ZrO2涂层层间材料的热膨胀系数呈梯度变化，表现出最佳的抗热震性能。
In the present investigation, we determine the second Hankel determinant H2 (2) for a class of close-to-convex functions for which −z 2 f ‘(z)/g (z) g (−z) ≾ p φ(z) where φ(z) is an analytic function with the positive real part satisfying φ(0)= 1 and φ ‘(z)> 0, f is analytic and g is starlike of order 1/2.
