11. Nanotribology, Surface Interactions and Characterization : An AFM Study
Sammanfattning : When two surfaces achieve contact, then contact phenomena such as adhesion, friction and wear can occur, which are of great interest in many disciplines, including physics, physical chemistry, material chemistry, and life and health sciences. These phenomena are largely determined by the nature and magnitude of the surface forces such as van der Waals, capillary and hydration forces. LÄS MER
12. Tyre-road Interaction: a holistic approach to noise and rolling resistance
Sammanfattning : Energy dissipation, fuel consumption, real-estate property prices and health issues are some of the aspects related to the tyre/pavement interaction and its functional properties of rolling resistance and noise. The first two aspects are affected by the tyre/road interaction as energy is dissipated mostly by hysteretic losses as the tyre is subjected to dynamic deformations when contacting the pavement surface.

13. Atomic and Electronic Structure of III-V Semiconductor Surfaces
Sammanfattning : The atomic and electronic structure of clean and Cs-perturbed III-V semiconductors was studied by angle-resolved photoelectron spectroscopy (ARPES), surface core level spectroscopy (SCLS), and scanning tunneling microscopy (STM). The work can be divided into three parts, dealing with low-index sur-faces, high-index surfaces, and special features of InAs. LÄS MER
14. Investigation of electrochemical properties and performance of stimulation/sensing electrodes for pacemaker applications
Sammanfattning : People suffering from certain types of arrhythmia may benefit from the implantation of a cardiac pacemaker. Pacemakers artificially stimulate the heart by applying short electrical pulses to the cardiac tissue to restore and maintain a steady heart rhythm. By adjusting the pulse delivery rate the heart is stimulated to beat at desired pace. LÄS MER
15. Women's cattle ownership in Botswana : Rebranding gender relations?
Sammanfattning : Cattle are often portrayed as a male affair in Botswana. However, venturing out into the Kalahari countryside to scratch the surface of this state of affairs, another picture emerges. LÄS MER
