This thesis explores nano-scaled plasmonic solutions to the problem of light capture and distribution in microalgae cultivation schemes. An evaluation of the effect of light quality on productivity under different photobioreactor geometries shows a 2x increase in productivity under 630-nm red light for low density cul…
At 100-nanometer length scale, the mesoscopic structure of calcium silicate hydrate (C-S-H) plays a critical role in determining the macroscopic material properties, such as porosity. In order to explore the mesoscopic structure of C-S-H, we employ two effective techniques, nanoindentation test and molecular dynamics…
With the rapid development flexible electronics, there is a demanding need for fully flexible, lightweight energy storage systems with high energy and power densities. Herein, two major types of novel hybrid composite electrodes for electrochemical capacitors (ECs) were studied, namely substrate supported composite po…
Abstract : An intreocular insert based on fibroin was designed and optimized. The insert contains a hollow channel that was preloaded with the anti-VEGF antibody bevacizumab. The device was covalently coated with the antibacterial polymer HMPE1 to protect against biofilm formation and the transmission of harmful bacte…
Η παρούσα διδακτορική διατριβή με τίτλο «Χρήση του D-λεμονενίου ως μονομερούς σε αντιδράσεις πολυμερισμού καθώς και ως βελτιωτικού των ιδιοτήτων συμβατικών πολυμερών», πραγματοποιήθηκε σε τέσσερα διαφορετικά στάδια. Το πρώτο μέρος της διδακτορικής διατριβής περιλαμβάνει τη χρήση του D-λεμονενίου ως μονομερούς, για τη…
An in-reactor experiment is being designed in order to validate the pellet-cladding mechanical interaction (PCMI) behavior of the BISON fuel performance code. The experimental parameters for the test rod being placed in the Halden Research Reactor are being determined using BISON simulations. The 3D model includes a m…
La thermogravimétrie isotherme et isobare permet de mesurer la vitesse de transformation chimique de solides massifs ou divisés. L’exploitation des courbes cinétiques repose sur la séparation des variables temps et des variables thermodynamiques dans l’équation de vitesse. Des modèles «géométriques» décrivant les vari…

Abstract : The interfacial and bulk electronic structure and charge transport properties of amorphous hydrogenated boron carbide (a-BC:H) were investigated toward its application in solid-state direct-conversion neutron detection. From photoemission spectroscopy and current-voltage measurements, it was found that a ra…
Interest in transparent conducting oxides (TCOs) has intensified over the past decade, driven by the requirement to find a suitable replacement to indium tin oxide (ITO). Of the many possible candidates identified, zinc oxide (ZnO) was selected owing to its favourable optical properties, abundance, low toxicity and ch…
Supramolecular chemistry, the domain of chemistry ‘beyond the molecule’, is finding increasing application in a diverse range of scientific fields. A key concept in this field, termed molecular self-assembly, has important applications ranging from nanotechnology to medicine, and refers to the intermolecular assembly…
The objective of this study is to determine the initial shear modulus of silicone rubber reinforced with different concentrations of alumina nanoparticles. The experimental data were obtained from a master's dissertation, where composite samples were subjected to a pure shear test. To determine the values of the five…
The study of the Fleischmann–Pons Effect (FPE), i.e. the production of excess power production during electrochemical loading of deuterium in palladium (in the past labeled cold fusion) has had a notably multidisciplinary character, involving solid state and nuclear physics, material science, electrochemistry and othe…
Nickel alloys have found ever increasing use in the nuclear sector in recent times. Inconel X750 and other nickel-based alloys are used in the construction of reactor fuel channels. Thermal neutrons cause transmutation of nickel, and the nuclear reactions that take place within some nuclear reactor components result i…
석탄재로부터 제조된 지오폴리머에 골재를 첨가하여 시멘트와 동일하게 모르타르와 콘크리트를 제조하는 것이 가능하다. 잔골재의 특성이 지오폴리머 모르타르와 콘크리트에 미치는 영향에 대해 체계적으로 검토한 연구는 많지 않기 때문에 잔골재의 광물조성, 형상, 표면, 입도, 밀도 및 흡수율 등을 평가하는 것이 필요하다. 본 연구에서는 석영, 운모, 장석, 휘석 등의 광물 조성을 이루고 -0.60mm에서 +0.30mm까지의 입자크기가 전체의 96%이며 표면이 거칠고 각진 형상을 보이는 주문진 표준사와 대부분 석영으로 -1.40mm에서 +0.60mm까지의 입자크기가 전체의 51%…
Bronze -40%w Composites are successfully prepared by compacted mixtures powder into pellets. The green compacts of (bronz– 40wt%W) were sintered for (60- 120 min) at 750, 850, 950°C. Scanning Electron Microscopy (SEM) technique was used for microstructure test of the raw powders, and composites. The results obtained r…
The work discussed in this thesis represents the accumulation of research I performed throughout my doctoral studies.My studies were focused towards two-dimensional electronic transport in semiconductor and perovskite oxide interfaces.Electronic materials with low dimensionality provides experimentalists and theorists…
Most of the toxicity assays were developed for the evaluation of conventional drug compounds in vitro. In fact, researchers have realized that not all cytotoxic and genotoxic assays are appropriate for the evaluation of nanoparticle toxicity as several nanoparticles are capable to interfere with these methods. For ins…
Focused on the quad-band generalized negative-refractive-index transmission line (G-NRI-TL), this thesis presents a variety of novel printed G-NRI-TL multi-band microwave device and antenna prototypes. A dual-band coupled-line coupler, an all-pass G-NRI-TL bridged-T circuit, a dual-band metamaterial leaky-wave antenna…
