1. Emissioner av nanotrådar från epitaxisubstrat
Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologiSammanfattning : Morfologiska likheter med asbest tillsammans med toxikologiska studier i celler och försöksdjur har väckt oro för de potentiella hälsoriskerna om nanotrådar kan bli luftburna och inandas vid hantering. Nanotrådar växta på substrat genom epitaxi kan riskera att skadas under hantering vid förberedelse för analys i mikroskop och detta examensarbete ämnar undersöka huruvida nanotrådar eller fragment av dessa kan lossna från substratet och bli luftburna då detta händer.

2. AI Trained to Predict Thresholds of 2D Ellipse Percolation Systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Percolation theory is a relevant area of research in Nanotechnology because of its wide applications in nanoelectronics based on thin films of nanoparticles and composites, amongst others. In nanotechnology, systems are often explored through modelling and simulations. LÄS MER
3. Biofilm growth on super-acidic metal-oxide films
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : In nature, urea is hydrolyzed to ammonia and bicarbonate primarily by enzymes called ureases. As urine waste contains multiple important plant nutrients, there is interest in the waste treatment field to use urine waste products as plant fertilizers. LÄS MER
4. Towards the detection of single photons in the mid-infrared
Master-uppsats, KTH/Tillämpad fysikSammanfattning : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms. LÄS MER
5. Fabrication and Characterization of Nano-Confined Pd Catalysts for CO Oxidation
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance of these nanoporous structures.
