Modelling of metal cutting tool wear based on Archard’s wear equation
This article deals with an essential problem in the metal cutting industry, the problem of predicting tool wear and tool life. This is also a problem that has been studied by academia for the last century, often with very little added knowledge. The possibility to replace a large number of systematic wear tests with only a few specially designed tests provides new potentials for rapid information

Synthesis of Indole Alkaloids and Development of New Methodology
Natural products are compounds that exist naturally in living organisms, e.g.,plants, animal and fungi. These compounds are likely biologically active and canbe used as pharmaceuticals for various diseases. Evolution has made it possible forliving organisms to produce these natural products as a defence mechanism againstvarious threats. In most cases, the organism only produces a small amount of tThis thesis describes our efforts towards the total synthesis of natural products and the development of a newmethodology to afford a synthetically important scaffold.Chapter 2 outlines our efforts towards the total synthesis of a marine natural product, perophoramidine as wellas our completed synthesis of dehaloperophoramidine. The focus of the studies was to develop an efficient andconcise strat
Structural Changes in a Single GaN Nanowire under Applied Voltage Bias
GaN nanowires (NWs) are promising building blocks for future optoelectronic devices and nanoelectronics. They exhibit stronger piezoelectric properties than bulk GaN. This phenomena may be crucial for applications of NWs and makes their study highly important. We report on an investigation of the structure evolution of a single GaN NW under an applied voltage bias along polar [0001] crystallograph

The η′-carbon potential at low meson momenta
The production of η′ mesons in coincidence with forward-going protons has been studied in photon-induced reactions on 12 C and on a liquid hydrogen (LH 2 ) target for incoming photon energies of 1.3–2.6 GeV at the electron accelerator ELSA. The η′ mesons have been identified via the η′ → π 0 π 0 η → 6γ decay registered with the CBELSA/TAPS detector system. Coincident protons have been identif
