\n Nesta Tese foram preparados, em solução, filmes híbridos de argila e poliestireno provenientes de copos descartáveis comercializados no mercado brasileiro, com acetato de etila e glicerol. Posteriormente, foi adicionado o Hemi-hidrato de sulfato de cálcio como carga de reforço. Tanto a argila quanto o glicerol, ass…
The first "planned" macrocycle synthesis by the Busch group was reported at the 142cd National American Chemical Society meeting in 1962. This macrocycle, a 14-membered N2S2 ring compound, was prepared by taking advantage of the ability of Ni(II) to hold the two ends of one of the reactants in place for the ring closi…
Cyclodextrin (CDs) are known to form inclusion complexes with small molecules and ions. The authors found that CDs formed inclusion complexes not only with small molecules but also with various polymers with high selectivity. We have prepared polyrotaxanes by capping the both ends of the polymers in the polyrotaxanes…
Nanocomposites consist of graphene dispersed in matrices of soft materials are promising thermal management materials. A fundamental understanding of the thermal transport at graphene-soft material interfaces is essential for developing these nanocomposites. In this dissertation, thermal transport at graphene-octane i…

It is well established that the occurrence of superconductivity in iron pnictides is closely related to the tetragonal to orthorhombic structural and antiferromagnetic (AFM) phase transitions. It, however, has not been clear whether the same scenario is appropriate for iron chalcogenide counterparts due to the absence…
The research area of “molecular machines” based on interlocking ring compounds started a bit more than two decades ago with the synthesis of molecules or molecular assemblies, which could be set in motion using various types of signals (photonic, electrochemical or chemical). The complexity of the systems gradually in…

In this paper, we study the generalized phase retrieval problem: to recover a signal $\bm{x}\in\mathbb{C}^n$ from the measurements $y_r=\lvert \langle\bm{a}_r,\bm{x}\rangle\rvert^2$, $r=1,2,\ldots,m$. The problem can be reformulated as a least-squares minimization problem. Although the cost function is nonconvex, the…
The current book chapter focuses on the metal-coordination complexes of pyrogallol[4]arenes and resorcin[4]arenes. Pyrogallol[4]arenes have been shown to complex with copper, nickel, zinc, gallium, holmium, silver, cadmium and cesium, whereas resorcin[4]arenes have been shown to complex with silver and zirconium. Dire…
This chapter provides a short introduction to metal-organic compounds, starting from fundamental examples of coordination chemistry dated back to the end of the 19th century. The historical overview covers Werner complexes and Hofmann clathrates that enable fundamental studies based on molecular porous crystals and mu…
Zinc oxide (ZnO) films and substrates are important and attractive materials for applications in several fields. The Properties of ZnO films, glass and ZnO/ glass have been studied by using ion beams. The effects of glass substrates on physical properties of ZnO films have been investigated. Details of calculations me…
Optical properties of a fluorescence molecule can be drastically changed by surface plasmons excited in neighboring metallic nanostructures. Here we investigated the fluorescence enhancement behavior of fluorescein isothiocyanate (FITC) labeled polystyrene nanoparticles coupled to silver island films (SIFs) via a 15 n…
A dense protective layer has to be applied onto ferritic stainless steel metallic interconnects for solid oxide fuel cell (SOFC) stacks to prevent a rapid performance degradation caused by chromia scale growth and chromium poisoning of the cathode. Manganese and cobalt spinel oxide (MCO) is known as an effective prote…
U ovom je zavrsnom radu provedeno ispitivanje otpornosti otisaka offsetnih termokromnih boja prema otiranju. U svrhu pronalaženja optimalne tiskovne podloge za navedene boje, otiskivanje se izvrsilo na razlicitim tiskovnim podlogama. Tako su se dvije offsetne termokromne boje (vinsko crvena i zelena) u laboratorijskim…
Durability and reliability of anode supported SOFC stacks have proven unsatisfactory in large scale trials, showing rapid failure, thermal cycling intolerance and step change in electrochemical performance most likely related to mechanical issues. Monitoring and understanding the mechanical conditions in the stack esp…

Abstract The AISI 4130 steel grade is commonly used in piping systems, where optimum chemical composition and heat treatment can exhibit high yield strength, good ductility, and moderate weldability depending on composition. However, this steel grade is characterized by its low hardenability, which limits a good trans…
