Two cadmium apatites, Cd5(PO4)3Br and Cd5(VO4)3I, earlier reported to be halogenide deficient, were prime suspects of being modulated. In this study, incommensurate ordering was found in satellites occurring in planes perpendicular to c*. The structure of Cd5(PO4)3Br was refined from single-crystal X-ray diffraction data in the four-dimensional super space group R:P3̄:(00γ): a = 16.932(2) Å, c = 6
The electrical resistivity, ρ, of one-dimensional quasiperiodic η8-Cu5Sn4 has been studied, and compared with crystalline Cu6Sn5 of identical basic structure (B8) and closely related atomic structure. ρ was measured between 1.5 and 300 K on needle-shaped crystals with their axes along the base lattice c direction, corresponding to the quasiperiodic direction in η8-Cu5Sn4. ρ (4 K) was found to be n
Mozambique is one of the largest coal exporters in Africa. Usually miningactivities generate polluted water that is discharged into the Zambezi river basin in the Moatize area without treatment, increasing the risk both to the local environment and to public health because of this water containing significant amounts of metals and metalloids. At the same time, Mozambique is one of the largest prod
The aim of this study is to develop a better understanding of the relation between housing recovery and user involvement from a capability perspective. The thesis studies housing recovery in areas affected by typhoon Haiyan, which struck the Philippines on 8th November 2013. The focus is on three perspectives: a) approaches to housing reconstruction, b) explanation for unexpected housing outcomes,
This thesis describes charge transport in III-V narrow bandgap semiconductor nanowires. We are particularly interested in quantum transport in InSb, InAs and InP-InAs core-shell nanowires. According to the type of transport mechanism dominating in the devices, this thesis can be divided into four parts.In the first part of this thesis, we investigated the temperature dependent transport properties
Re-excavations of forgotten archaeological material are more relevant than ever. What is not ordered published or digitized risks to become invisible in storages and archaeological research. With new investigations of archaeological contexts and osteological material the article updates our knowledge of Late Bronze Age burials in North-Western Skåne, Sweden.
From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur
