Magnetic skyrmions have the potential to provide solutions for low-power, high-density data storage and processing. One of the major challenges in developing skyrmion-based devices is the skyrmions' magnetic stability in confined helimagnetic nanostructures. Through a systematic study of equilibrium states, using a fu…
Η παρούσα διατριβή αποτελείται από δύο επιμέρους κεφάλαια τα οποία συνδέονται μεταξύ τους όπως συνοπτικά περιγράφεται παρακάτω. Αρχικά, σχεδιάσαμε και συνθέσαμε ένα μόριο που μπορεί να δρα ως πολυφορτιακό όχημα παράδοσης φαρμακευτικών ουσιών και δύναται να ρυθμιστεί ενάντια σε συγκεκριμένα καρκινικά κύτταρα (κεφάλαιο…
An advanced layers of protection analysis (LOPA) method is proposed in this study for assessing the risk associated with a chemical process. It is difficult to determine the values of the acceptable risk for accident scenarios and the probability of failure on demand (PFD) for emergency protection using the traditiona…
The requirement of participation in interlaboratory comparisons was not sufficiently fulfilled by laboratories in the field of explosion protection (Ex-testing laboratories) due to a lack of proficiency testing programs. The reasons were the extensive effort, the complexity of the relevant measurands- and characterist…
CSB (US Chemical Safety Board) identified 281 combustible dust incidents between 1980 and 2005 that killed 119 workers, injured 718 others and damaged several industrial facilities. These incidents occurred in 44 states, many different industries and involved a variety of different materials. Seven of the incidents, w…
Deflagration tests were conducted with two kinds of autoclaves. Parameter studies were carried out concerning the gas atmosphere and substances used. Deflagration tests were performed in different pressure regions. Furthermore, deflagration test results of different substances were compared to the corresponding DSC re…
We report on the manufacturing of nanopore through-holes by heating gold nanoparticles on a silicon oxide (SiO2) sheet, suspended in a silicon-rich nitride membrane (SiRN). Membrane patterning is performed using self-alignment by an internal shadow mask based process. A benefit of this approach is the ease at which do…
We conduct thermal investigation of mid IR coupled mode on the platform of a highly dense plasmonic nanostructure. The multi-physics study is consist of broadband Fourier transform infrared (FTIR) spectroscopy interfaced with an adiabatic system for heat flow control. A hybridized mode is excited by leveraging the vib…
Water filling of carbon nanotube bores in the 4-15 nm diameter range is experimentally evaluated by means of tracking proton transport through a carbon nanotube membrane. A membrane with empty bores is installed between to reservoirs, one containing a significant concentration of free protons. Water fills nanotube bor…
Over the last decade a number of peptides that are rapidly internalized by mammalian cells have been discovered or designed. Cell‐penetrating peptides (CPPs) are capable of mediating penetration of the plasma membrane, allowing delivery of macromolecular cargoes to the cell interior. We have developed a novel CPP‐adap…
In this work, the applicability of poly aromatic amines (PAA) for the removal of gold, copper and palladium from various water samples has been investigated. Batch experiments were performed to realize the effect of relative nitrogen/carbon composition on the ability of PAA for removal of aqueous metals to achieve qua…
This thesis’s main focus is a CO2 capture technology known as chemical looping combustion (CLC). The technology is a novel form of combustion and fuel processing that can be applied to gas, solid and liquid fuels. By using two interconnected fluidised-bed reactors, with a bed material capable of transferring oxygen fr…
We report on the hydrothermal growth of ZnO nanorods directly on GaN templates with a different density of dislocations. The influence of the quality of the GaN substrate on morphological and optical properties of ZnO nanorods is presented. The morphology of the ZnO nanorods was investigated by scanning electron micro…
Electrodeposition on aluminium alloy substrates often is often difficult in producing a coating with good adhesion when compared to other metals. This is due to the rapid formation of oxide layers on the substrate’s surface when exposed to air and water, preventing metallic bonds from forming between the nickel coatin…
In nanocrystallography, diffraction images are captured to gain insights into the structure of macromolecules. A new generation of experiments is able to take a vast amount of images in a short time. However, most of the images are not suitable for further research. It is not feasible to store and process all images i…
The oxides of iridium, a 5d transition metal, have recently attracted interest in a number of scientific disciplines, ranging from fundamental solid state physics, to more applied areas of research such as spintronics and catalysis. The metallic oxides IrO2 and Bi2Ir2O7, in particular, are known to be good catalysts o…
In this work, we used different pyrenes derivatives with a carboxylic acid group to modify the surface of carbon nanotubes (CNTs). This non-covalent method of functionalization can improve the dispersion of CNTs in organic solvent without damaging the desired properties of CNTs. Thin films of CNTs functionalized with…
In the field of the fabrication of micro- and nano-spheres, the phenomenon of Plateau-Rayleigh instability has drawn more and more attention. This surface tension-driven instability in two immiscible fluids can be used to generate uniformly size micro- and nano-spheres by imposing an external mechanical excitation. In…
In this paper, we present a novel compressible solid-state supercapacitor with PVA/H3PO4solid-state electrolyte and folded carbon-nanotube (CNT)/paper electrode. In this structure, both of the compression tolerance of folding structure and the strain capability of CNT film contribute to achieve high compression-tolera…
UV light source and high-pressure mercury lamps are usually used as a projecting light source of foreign exposure light source recently, including a spherical mirror ellipse, an optical integrator, and a parallel lens. The light source system is the most crucial technology to achieve better image quality and better un…
