A lattice model for binary mixture of lipids and water is introduced and investigated. The orientational degrees of freedom of the amphiphilic molecules are taken into account in the same way as in the model for oil-water-surfactant mixtures introduced earlier by Johan Høye and co-authors. The ground state of the mode…
A series of air permeance tests were performed on test panels constructed of clay brick and mortar according to ASTM E2178-11: Standard Test Method for Air Permeance of Building Materials. Four sets of brick were included in the test which represented a range of brick configurations. Typically, very low values of air…
A new synthetic methodology for the combinatorial preparation of C-terminus-modified Green and Red Fluorescent Protein chromophores is described. This method involves the modification of the previously reported [2+3] cycloaddition reaction scheme to incorporate new R2 groups in the imidate used in the final step. This…
The grinding ball mills are equipments present in mining plants, being important in the ore comminution circuits.Depending on numerous factors, such as, for example, design, manufacturing, overloads, poor maintenance and inadequate operating procedures, flaws are developed in the structural components of this equipmen…

By the first principles calculations and X-ray diffraction simulations, we perform a systematic study of multiple superconducting phases of potassium-doped picene [Nature {\bf464} 76, 2010]. The combination of optimized lattice parameters, formation energy, and simulated X-ray diffraction spectra indicates that the su…
This study aims to obtain nano-sized magnetite nanoparticles and study the effect of temperature on the function of the crystal structure of magnetite nanoparticles. Synthesis is done by mixing natural sand with HCl as solvent and NaOH as a precipitant ultrasonic. Function of temperature was varied from 30⁰ C, 50⁰ C,…
This thesis is divided into two parts, experimental part presenting the synthesis of exchange spring magnets and theoretical part showing the magnetization dynamics of exchange spring magnets. For the synthesis, ferrite and metal alloy based magnets using mechanical milling and ultrasonic mixing are studied. This part…
Soot released to the atmosphere is a dangerous pollutant for human health and the environment. Understanding the physical properties and surface properties of these particles is important to properly explaining the growth of soot particles in flames as well as their interactions with other particles and gases in the e…
The achievable beam current and beam quality of a particle accelerator can be limited by the build-up of an electron cloud (EC) in the vacuum chamber. Secondary electron emission from the walls of the vacuum chamber can contribute to the growth of the electron cloud. An apparatus for in-situ measurements of the second…
In dieser Dissertation wurde die Beziehung zwischen den strukturellen, optischen und Ladungstransporteigenschaften von dotierten ZnO- und Zn1-xMgxO-Schichten eingehend untersucht. Das Ziel war es, die oben genannten Zusammenhänge weiter aufzuklären, wodurch sich anschließend Ansätze für eine zielgerichtete Verbesserun…
Nanosilicon: Properties, Synthesis, Applications, Methods of Analysis and Control examines the latest developments on the physics and chemistry of nanosilicon. The book focuses on methods for producing nanosilicon, its electronic and optical properties, research methods to characterize its spectral and structural prop…
Zinc oxide (ZnO) in its nanostructured form is emerging as a promising material with great potential for the development of many smart electronic devices. This book presents up-to-date information about various synthesis methods to obtain device-quality ZnO nanostructures. It describes both high-temperature (over 100…
Liquid crystals (LCs) are ubiquitous in everyday life in the form of liquid crystal display (LCD) devices, which currently outnumber the people on earth. LCs are unique functional soft materials th...

Abstract Title catalyst is synthesized and characterized.
The cobalt doping effects on the lattice constant, strain, grain size, dislocation density and electrical conduction are investigated by means of X-ray diffraction and electrical resistivity measurements on the Bi1.5Zn0.92Nb1.5–xCoxO6.92–x (x=0.03-0.20) ceramics, respectively. Increasing cobalt content sharply increas…
An active and reusable heterogeneous Rh(I) organometal catalyst (Rh(I)-PMO-3D) was synthesized by template-directed co-condensation of Rh[PPh2(CH2)2Si(OCH2CH3)3]3Cl and (CH3CH2O)3SiPhSi(OCH2CH3)3. This catalyst displayed bicontinuous cubic Ia3d mesostructure channel, which ensured the high dispersion of Rh(I) active s…
We report synthesis of a series of new triarylamine-containing AB-type monomers and their polymers via nucleophilic aromatic substitution (SNAr) reaction. Monomers consisting of a hydroxyl group at the para position of the nitrogen group in one phenyl ring and a fluorine leaving group at the para position in another p…
Published in Journal of Computational Chemistry 2014, 35, 923–931; DOI: 10.1002/jcc.23577 In L. Belpassi and co-workers' paper (J. Am. Chem. Soc., 2008, 130 (3), 1048–1060), they have first proposed the charge displacement function, which is today a well established and successful tool for chemical bond analysis in a…
