High-density polyethylene (PE-HD) is a widely applied plastic for fuel storage tank applications. But such tanks, filled with diesel or biodiesel, provide excellent environmental conditions for growth of a broad spectrum of fungi and various bacteria1. This can result in fuel contamination, engine plugging or possible…
Chemical admixtures are widely used to adjust properties of the cementitious mixtures. Different superplasticizers (SP) are typically added to improve the flowability of the fresh cement paste. Their working period is the initial stage of the cement hydration from its beginning until stiffening. Currently, polycarboxy…
Ein wichtiger Industriezweig, der aufgrund immer größerer Anforderungen an die kostengünstige Herstellung hochpräziser Komponenten neue Fertigungslösungen fordert, ist die optische Industrie. In den letzten Jahren wurden für den Anwendungsbereich optischer Linsen verschiedene Replikationsverfahren optimiert oder entwi…
This thesis tackles several problems arising in robotics and mechanics: analysis and computation of two- and muti-body impacts, planning a contact velocity for robotic batting, impact of an elastic rod onto a fixed foundation, robotic pickup of soft three-dimensional objects, and recovery of their gravity-free shapes.…
This thesis presents a new approach for the synthesis of polymer nanostructures using a bifunctional reversible addition-fragmentation chain transfer (RAFT) agent, two types of modified organo-montmorillonites, such as a non-reactive dimethyldodecyl ammonium (DMDA)-MMT and a reactive octadecylamine (ODA)-MMT organocla…
In this study, thirty samples of cleaning materials (liquid) were collected from the local markets of Al-Najaf government to assess radium content and radon flux density (radon exhalation rate) using LR-115 Type II technique. These samples were divided into six groups according to country of origin (i.e. Iraq, Turkey,…
This paper work is based on a brief discussion of a recent project proposal, approved by the Croatian Science Foundation. The project proposal focuses on the application of the technique of electrospinning in the development of scaffold prototype to be used for in vitro culture of ocular and skin cells. A brief review…
Thermal properties of solids are one of the most important features studied in solid state physics, and many of the thermal properties are consequences of anharmonicity in solids. Many experimental techniques and theoretical methods have been successfully developed in the study of the anharmonicity and our understandi…
Series of monodispersed linear and star-shaped polyhydroxybutyrate (PHB)s were synthesized using controlled indium and zinc based complexes through immortal ring opening polymerization of β-butyrolactone (BBL) in the presence of benzyl alcohol, tris(hydroxymethyl)benzene, and dipentaerythritol chain transfer agents. T…

Electron correlations are the root of many interesting phenomena in materials, including phase transitions such as superconductivity and insulator-to-metal transitions, which are of great interest both for scientific understanding and for many applications. Such phase transitions can often be tailored in thin films, i…
Studies presented here work towards the analysis of post-translational modification of the essential ArsR transcription factor of Helicobacter pylori. A human health hazard, H. pylori contributes to the development of gastric cancer and peptic ulcers in its hosts. It is of interest to study the mechanisms that allow t…
In this thesis we explore various ways to extend population lifetimes and coherence times of solid-state emitters. We focus on rare-earth-ion doped host materials and silicon vacancy centers in diamond, both of which are used for applications in quantum information processing and quantum communications. Enhanced lifet…
OBJECTIVES: To investigate the effect of different ceramic powders on the microstructure, biaxial flexural strength, hardness and absorption coefficient of resin-infused zirconia and alumina, to investigate the effect of sintering temperatures on the microstructure, biaxial flexural strength, hardness and absorption c…
In binnen- en buitenland hebben verschillende niet-nucleaire industriële sectoren, zoals de olie- en gasindustrie, te maken met materialen die van nature radioactiviteit bevatten ('NORM'). Als gevolg van de productieprocessen kunnen reststoffen ontstaan die van nature radioactiviteit bevatten ('NORM reststoffen'). 'Re…
espanolLas baterias actuales estan basadas en materiales inorganicos como los oxidos o fosfatos de litio y sodio. Estos materiales son de origen mineral por lo que llegara un momento en el que se agoten y son generalmente toxicos, por ello, su sustitucion por materiales polimericos, los cuales se pueden obtener de fue…
Local defect structures are significant to determine material properties since defects introduced into host materials would affect the local/average crystal environments and thus lead to a change of macroscopic physicochemical performances. The intentional design of specific local defects not only depends on the selec…
Metallic biomaterials (titanium and titanium alloys) have been widely employed in many load-bearing orthopaedic applications, as they have excellent mechanical properties and corrosion stability. However, soaring problems such as a lack of direct chemical bonding between the implant and host tissues leading to implant…
Ce travail de these contribue a la comprehension et au developpement du procede d’oxydation avancee couplant l’ozone et le peroxyde d’hydrogene (procede peroxone O3/H2O2) en phase aqueuse. Ce procede permet la generation de radicaux hydroxyles particulierement reactifs et non selectifs, capables de conduire a la miner…
An ion trap is a device to confine charged particles by utilizing electromagnetic fields.Since the trapped ions have a feasibility of the individual state manipulation, a long coherence time, and an ideal isolation from the surroundings, the ion-trap technology becomes one of the leading candidates for the physical im…
