In the past decade, substantial advances in biochemistry and materials science, including surface science, have occurred, allowing a comprehensive description of processes and mechanisms on the molecular scale and, thus, a deeper understanding of the interactions between artificial implants and the host human body. Fr…
Carbon nanocoils (sometimes called coiled or helical carbon nan- otubes) are exotic nanomaterials having coiled geometry, resem- bling “telephone cords” attached to the phone receiver. They exhibit excellent mechanical properties, which owes to the combination of flexibility due to coil morphology and the toughness res…

A three-dimensional numerical simulation of the anode overpotential is conducted in a microstructure which is reconstructed by a dual-beam focused ion beam-scanning electron microscope. Gaseous, ionic and electronic transport equations are solved by a lattice Boltzmann method with electrochemical reaction at the three…
The anode is the electrode at which the fuel is oxidized in a SOFC. This chapter describes the required properties of anodes and the materials that have been developed for use with various fuels including hydrogen, methane, fuels from biomass, liquid fuels, and ammonia.
The nanoscale and nano‐structured electrode approach by infiltration method attracts increasing attention as the viable alternative for the development of highly efficient electrodes of solid oxide fuel cells (SOFCs). The infiltration method opens a new horizon in the advanced electrode development as the method expan…

Interconnects are one of the most challenging materials issues for solid oxide fuel cell (SOFC) stacks. They are exposed to both oxidizing conditions at the cathode and reducing conditions at the anode, at elevated temperatures, and must maintain good conductivity and good mechanical stability. Both ceramic and metall…
Solid oxide fuel cell (SOFC) is a promising energy conversion device with high efficiency, fuel flexibility and reduced emissions. An important tool in fuel cell development is mathematical modeling, which is particularly appropriate for SOFCs, where localized experimental measurements are difficult due to the high op…
Solid Oxide Fuel Cells (SOFC) are particularly promising for their capability to be integrated in complex power plants, showing ultra-high conversion efficiencies. This chapter investigates some possible layout configurations of hybrid power plants including both SOFC and Gas Turbine (GT) technologies. SOFC/GT power p…
On the course of ongoing search for alternative energy generation method, solid oxide fuel cells (SOFCs) running on alternative fuels have drawn increasing interest globally due to their high efficiency and critical role in environmental protection. In this chapter, our group’s work in this field is summarized in four…
Aim: Pancreatic ductal adenocarcinoma is one of the most aggressive and deadly malignancies. Despite considerable knowledge about the cell biology and the genetic changes of malignant cells, therapeutic options for pancreatic adenocarcinoma remain ineffective. One plausible explanation for the poor tumor response to t…
Einleitung: Die zahlreichen Nebenwirkungen einer systemischen Chemotherapie können durch eine lokale, zielgerichtete Applikation des Wirkstoffs vermieden werden. Dies ist mit m agnetischen N ano p artikeln (MNP) möglich. Die MNP werden dabei in Magnetoliposomen an ein Pharmakon gebunden und im Zielgebiet mithilfe von…
Einleitung: Die HIPEC verläuft derzeit nicht standardisiert. Variablen wie die Kombinationen der Zytostatika, Applikationsdauer und Hyperthermie beeinflussen die Therapieeffizienz. Zur Charakterisierung dieser Variablen und realitätsnahen Abbildung der klinischen Situation sind experimentelle Modelle unerläßlich. Folg…
Einleitung: Die Stentmigration ist insbesondere bei vollgecoverten selbstexpandierenden Metallstents (SEMS) eines der größten Probleme und liegt lage- und indikationsabhängig bei bis zu 30%. Sowohl verschiedene Stentmodifikationen im Design, als auch die bisherigen Fixierungshilfen erbrachten nur eine unzureichende Se…
Einleitung: Proteinaggregate sind charakteristisch für zahlreiche degenerative Erkrankungen. So werden Mallory-Denk-Körper (MDK) als zytoplasmatische Einschlusskörper bei Patienten mit alkoholischer und nicht-alkoholischer Steatohepatitis, aber auch bei adipösen Personen ohne steatohepatitische Veränderungen beobachte…
Aims: We previously established a role for HSP27 as a prognostic and predictive marker in pancreatic cancer: Tissue-microarray studies showed increased HSP27 expression in pancreatic cancer specimens to be associated with better patient survival, while HSP27 overexpression unexpectedly increased susceptibility specifi…
Einleitung: Die cytoreduktive Chirurgie mit HIPEC konnte als Therapie bei ausgewählten Patienten mit Peritonealkarzinose bei gastrointestinalen Tumoren etabliert werden und ist bei kompletter Tumorresektion mit einem verlängerten Überleben verbunden. Bislang ungeklärt ist die Beeinflussung der Lebensqualität nach zyto…
The title complex, K2[Ni2(C6H5O7)2(H2O)4]·4H2O, is a dinuclear centrosymmetric anionic octa-hedral complex, involv-ing citrates as tridentate and bridging ligands, and coordinating water mol-ecules. An extensive network of hydrogen bonds connects the complex anions through the two unique uncoordinating water mol-ecule…
This paper addresses the problem of improving the loss factor of carbon-epoxy laminates with embedded viscoelastic layers. A cork based agglomerate was elected as viscoelastic material due to its low weight combined with excellent damping properties, showing a great potential for vibration control. A micro-sandwich ty…
