Fischer-Tropsch synthesis over supported cobalt catalysts is an important industrial process for the conversion of synthesis gas to hydrocarbons. Although enormous efforts have yet been devoted to understand the fundamental aspects of the Fischer-Tropsch synthesis, the influence of the support structure still remains…
We performed XRD observations of laser-shock compressed highly oriented pyrolytic graphite along the [002] orientation using an x-ray free electron laser: SACLA. The x-ray diffraction detector recorded x-rays that are diffracted from multiple lattice planes. These diffracted x-rays indicate both uncompressed and compr…
This PhD thesis studies fabrication of superhydrophobic polymeric surfaces, their wetting properties, and their antibacterial activities as potential application to medical sciences. A femtosecond laser technique was used to fabricate mico/nano- structures on the surface of PTFE and PU. The effect of laser parameters…
Zip files of results of calculations using molecular dynamics over 15 ns (AMBER10) on a DNA oligomer in explicit water (TIP3P).
Scanning tunnelling microscopy can be used to study metal surfaces on an atomic level. An interesting\nmetal to study is lead because it is superconducting below 7.2 K. With a scanning tunnelling microscope\nsingle molecules like CO can be manipulated to build artificial structures. These structures confine\nthe elect…
Scanning electrochemical microscopy (SECM) employs a biased ultramicroelectrode (few nm to 25 µm diameter) as a probe that is scanned over a sample to electrochemically characterize its physical properties and chemical reactivity with high temporal and spatial resolutions. In this dissertation, SECM was used to invest…
På grund av allt hårdare miljökrav från EU och nedläggningen av kärnkraften så kommer vattenkraft, vilket redan spelar en stor roll för dagens energiproduktion, behöva utökas. På grund av detta behövs en hållbarare och billigare lösning på tekniska fiskvägar, vilka idag oftast gjuts i betong. En av lösningarna som för…
X-ray surface diffraction experiments performed on polyaniline/camphorsulfonic acid (PANI/CSA) thin films reveal high anisotropy of the five main crystalline peaks. This anisotropy is different for samples cast from m-cresol and cast from trifluoroacetic acid (TFA). Taking advantage of a recently published crystalline…
The ability to make measurements and manipulate matter at micrometer and nanometer scales will have far-reaching applications. In the past decade, significant progress has been made in developing microscale and nanoscale motors that can be used for targeted delivery. These advances are not without complications, howev…
针对Sn-Al体系不易混熔的难点,通过粉末压片与真空电弧熔炼相结合的方法,成功制备了添加稀土的Sn-Cu-Al无铅焊料,并研究了添加微量单一稀土Ce、La和混合稀土RE对其显微组织和可焊性（熔化特性、润湿性）的影响。实验结果表明,不同稀土的添加均能使Sn-0.7Cu-0.075Al合金的组织均匀细化,单一稀土Ce、La的添加对基体合金的细化效果优于混合稀土RE的。单一稀土Ce、La的添加使基体合金的熔点从229.82℃分别降低到227.06℃和227.38℃,而混合稀土RE的添加对基体合金熔点影响不大,不同微量稀土的添加均略微降低了基体合金的熔程。不同微量稀土的添加均改善了基体合金的润湿性能。其中,单一稀土Ce的改善作用最明显,使…
I smelteverk produseres metall ved svært høy temperatur, noe som blant annet fører til dannelse av termisk NOx. Denne oppgaven tar utgangspunkt i målinger av avgassen som kommer ut ved tappingen av metallet, som ble målt i forbindelse med doktorgraden til Kamfjord i 2012. Det er da observert en forhøyet konsentrasjon…
This study deals with polypropylene (PP) which was subjected the drop-weight test. PP is a semicrystalline thermoplastic polymer which is commonly used in many indoor applications and also in the automotive industry in the car interiors. The injection moulded PP samples were subjected the penetration test at different…

This thesis presents a series of studies pertaining to tribological, thermal, kinetic and slurry utilization aspects of chemical mechanical planaraization processes. The purpose of this work is to both develop a better method of characterizing the tribological mechanisms during polishing, as well as propose methods by…

In this work, carbon-based conducting electrodes based on two different types of carbon nanofibers (CNF) have been produced by the dip and dry coating method onto cotton substrates. Furthermore, activated carbon (Norit A Supra Eur) and manganese oxide (MnO2) have been subsequenlty added to the CNF-based dip-coated cot…
A simple model has been used to investigate the nature of chemical order in Na-Pb and Na-Hg liquid binary alloy at 700K and 673K respectively. The energy parameter obtained from the model was used to calculate the concentration dependent mixing properties such as Gibb’s free energy of mixing, Concentration fluctuation…
