In this work, we present results from atomistic simulations of gold nanowires under axial compression, with a focus on examining the effects of both axial and surface orientation effects on the buckling behavior. This was accomplished by using molecular statics simulations while considering three different crystallographic systems: <100>/{100}, <100>/{110} and <110>/{110}{100}, with aspect ratios
The major challenge in the development of new polymer membranes for fuel cells lies currently in the demand for durable membranes that allows fuel cell operation at high temperatures without extensive humidification requirements. Access to these membranes promises important benefits concerning the complexity, cost and performance of the fuel cell system. In this context, membranes functionalized w
The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. The molecular methods showed a low level of diversity and it was apparently lower as the environment becam
The subject of this thesis is intellectual property and protection of non-commercial societal interests. The study is divided in two main parts. The first part deals with the provision of the Swedish Copyright Act laying down that literary and artistic works may not be performed or reproduced publicly after the death of their author in a manner that violates cultural interests (protection for clas
We present the results of multiple simulations of open clusters, modelling the dynamics of a population of brown dwarf members. We consider the effects of a large range of primordial binary populations, including the possibilities of having brown dwarf members contained within a binary system. We also examine the effects of various cluster diameters and masses. Our examination of a population of w
Field asymmetric ion mobility spectrometry (FAIMS), also commonly termed differential mobility spectrometry (DMS), is a gas-phase ion separation technology. FAIMS exploits differences in high-electric-field to low-electric-field ion mobility ratios to discriminate between ion species. FAIMS and mass spectrometry (MS) provide generally orthogonal ion separation and are easy to interface. One of the
