In this thesis, numerous different compound classes were investigated using different mass spectrometers. Thereby, the focus was set on the formation, structure and aggregation of ions formed from porphyrin/phthalocyanine-fullerene derivatives as well as organometallic complexes. In the first chapter, it was possible…
En este estudio se utilizaron diferentes soluciones de poli (acido lactico) (PLA), colagena (COL) y elastina (ELAS) para la fabricacion de andamios de microfibras y nanofibras mediante la tecnica de electrohilado. Posteriormente, celulas musculares lisas de vejiga de conejo neozelandes fueron sembradas en los andamios…
Eddy current testing is commonly applied on austenitic stainless steel. 304 austenitic stainless steel always deforms during the process of manufacture or in service. The undesired deformation creates ferrite and martensite which causes a change of permeability. In that case, the non-magnetic austenitic stainless stee…

Outer-wear is the external layer which as responsible for than 90% from dealing with UV where falls on the perso. body. an important value in this paper is designed to investigate the clothes esisting efficiency against harmful UV radiation. So it to determine the more effective texture structural factors, in relation…
Lignocellulosic biomass, the primary building block of plant cell walls, consists of three main components, i.e. cellulose, hemicellulose and lignin. A rather important, but in current processes inefficiently used substance of this biomass is lignin. Lignin is a natural occurring complex biopolymer found in the cell w…

【Objective】The relativity between asymmetric nuclear division and strain degeneration was discussed to elucidate mechanism of strain degeneration in Volvariella volvacea. 【 Method 】 Three degenerated Volvariella volvacea strains were selected according to RAPD markers and colony morphology. The number and size of nucl…
Flash point is a primary property used to determine the fire and explosion hazards of a liquid. New group contribution-based models were presented for estimation of the flash point of alkanes by the use of multiple linear regression(MLR)and artificial neural network(ANN). This simple linear model shows a low average r…
Symmetry-element diagrams of some point groups [adapted from Vainshtein (1994)]. The point groups are specified by their Schoenflies and Hermann–Mauguin symbols. (a) C2 = 2, (b) , (c) D3 = 32, (d) C4h = 4/m, (e) D6h = 6/m2/m2/m, (f) C3v = 3m, (g) , (h) T = 23. [The cubic frame in part (h) has no crystallographic meani…
Abstract. Energy and raw material costs, an increase in environmental pollution, greenhouse gas emissions, global warming, depletion of fossil raw materials stimulate to seek and study alternatives to the synthetic fibers and products made of them for full or partial replacement. Renewable raw materials, including nat…
For weight reducing and functional reasons, hollow shafts should be used in gear units in the near future. Inside they have a big cylindrical cavity, which is only accessible through small inlet holes. This cavity may have large diameter variations along its length. There is an undesirable scale-formation, if high tem…
Die Dissertation behandelt zwei Ansätze zur Herstellung und Charakterisierung von Silizium-Hybridstrukturen für nichtlinear optische Anwendungen. Zunächst wurden global infiltrierte zweidimensionale photonische Kristalle hergestellt und untersucht. Hierbei konnte eine statische Änderung ihrer Bandstruktur nachgewiesen…
In dieser vorliegenden Dissertation wird mit Hilfe von numerischen Simulationen der Einfluss der spannungsinduzierten Doppelbrechung auf die Eigenpolarisationszustände von Festkörperlasern untersucht. Es werden die grundlegenden physikalischen Zusammenhänge zwischen den thermischen, mechanischen und elektromagnetische…
Grinded quartz sand was used as the main material in the production of conventional autoclaved aerated concrete (AAC). Swelling is achieved, the aluminum powder adding into the fluid consistency mortar, that prepared with silica sand, cement and lime. That high pressure steam curing is applied to the molds for gain st…
The aim of this study is to investigate the effect of solution treatment on the corrosion behavior of Mg- 8%Al-(0-1)%Zn casting alloys in 1M NaCl aqueous solution. After the solution treatment, all alloys showed single α-(Mg) phase microstructure by dissolution of β(Mg17Al12) phase into the α-(Mg) matrix. The H2 evolu…
Natural antioxidants derived from marine algae have a high content of bioactive components with potential for improving oxidative stability of lipids in food systems. In this presentation I will discuss results from our ongoing work on the brown algae, Fucus vesiculosus. This seaweed contains a wide range of polypheno…
Experiments and finite element analysis are used to investigate the alignment of carbon nanotubes through the thickness of unidirectional glass-epoxy composites using an alternating electric field.
The interfacial interaction between block copolymer(BCP) chains and surfactant surrounding the emulsion droplet greatly affects the final shape and internal morphology of BCP particles. Herein, we report a strategy for controlling the shape and internal morphology of poly(styreneb-5-vinylpyridine) (PS-b-P4VP) particle…
The main objective of this thesis was the design and synthesis of perylene bisimide dyes with sufficient water-solubility for the construction of self-assembled architectures in aqueous solutions. Beside these tasks another goal of this project was the control over the self-assembly process in terms of aggregate size…
