1. Heterogenization of a Cobalt Porphyrin Catalyst Investigated by Scanning Probe Microscopy and X-Ray Photoelectron Spectroscopy: The Effect on Catalysis of Oxidation Reactions
Sammanfattning : Construction of advanced materials through self-assembly on the molecular level is an important route to achieve novel functionality. Self-assembly of thiols onto gold has during the last decades shown greate promise in the creation of functional nanomaterials, such as sensors or catalysts, but for many applications silicon should be a better substrate since it offers semiconducting properties and better processing abilities in addition to being cheaper.

2. Near Wall Studies of Pulp Suspension Flow
Sammanfattning : .... LÄS MER
3. Heat Transfer and Hydrodynamics in Falling Film Evaporation of Black Liquor
Sammanfattning : The evaporation plant is one of the major steam consumers in kraft pulp mills, which are the dominant type of chemical pulp mill in Sweden. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER
4. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties
Sammanfattning : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.

5. Electrokinetic devices from polymeric materials
Sammanfattning : There are multiple applications for polymers: our bodies are built of them, plastic bags and boxes used for storage are composed of them, as are the shells for electronics, TVs, computers, clothes etc. Many polymers are cheap, and easy to manufacture and process which make them suitable for disposable systems.
