1. The Multiple Faces of Interfaces : Electron microscopy analysis of CuInSe2 thin-film solar cells
Sammanfattning : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. LÄS MER
2. Engineered temporary networks : Effects of control and temporality on inter-organizational interaction
Sammanfattning : The world is facing a growing threat of antibiotic resistance. The development of new antibiotics is of utmost importance; otherwise, we go back to the pre-antibiotic era where common infections become life-threatening. Despite this need for new antibiotics, a market failure is hampering its development. LÄS MER
3. Silicon δ-doping and Isoelectronic Doping in GaAs ans GaN Layers Grown by MBE
Sammanfattning : This work concerns MBE-grown material, particularly physical effects due to controlled impurities of Si and N in arsenides, and the growth of nitrides and studies of Al- and As-impurities in them. Apart from interesting physical phenomena there are important device applications. The first part is devoted to studies of Si .delta. LÄS MER
4. Influence of acid hydrogen peroxide treatment on refining energy and TMP properties
Sammanfattning : The potential of using acid hydrogen peroxide under Fenton conditions to lower the electrical energy consumed during the production of Black spruce (Picea mariana) thermomechanical pulp (TMP) was investigated. The chemical system, which consisted of ferrous sulphate, hydrogen peroxide and optionally an enhancer (3,4-dimethoxybenzyl alcohol, ethylenediaminetetraacetic acid or oxalic acid/sodium oxalate), was evaluated as an inter-stage treatment where the primary refiner was used as a mixer.

5. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties
Sammanfattning : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. LÄS MER
