1. Harnessing Mesoporous Spheres - transport studies and biotechnological applications
Abstract : Applications in controlled release and delivery calls for a good understanding of molecular transport within the carrier material and the dominating release mechanisms. It is clear that a better understanding of hindered transport and diffusion of guest molecules is important when developing new porous materials, e.g. READ MORE

2. Superporous agarose a new material for chromatography
Abstract : Agarose, the most commonly employed chromatography base material in industrial purification processes for biomolecules – proteins, has almost ideal properties. The major disadvantage of the agarose support is its poor mechanical strength which excludes its use in high speed separations where small particles are needed in order to achieve improved chromatographic efficiency.

3. Multi-scale fabric evolution during hydro-mechanical probing of fine-grained soils
Abstract : The majority of the studies on sensitive clays so far have focused on the hydro-mechanical response at engineering scale, using concepts from continuum mechanics. The fundamental mechanisms at particle scale, underpinning the emerging response, have so far been studied with post mortem analyses. READ MORE

4. Catalyst Deactivation by Coke Formation in Acetylene Hydrogenation
Abstract : Several aspects of catalyst deactivation have been studied with reference toselective acetylene hydrogenation, a reaction used industrially to purify ethylene from unwanted acetylene. A mathematical model has been developed for an industrial packed-bed reactor, employing a supported Pd catalyst. READ MORE

5. Bio-coal for the sustainable industry : A scientific approach to optimizing production, storage, and usages
Abstract : Bio-coal produced from biomass is a promising material to replace fossil coal in order to achieve net-zero greenhouse gas emission from the industrial sector. Bio-coal with quality comparable to that of fossil coal can be produced by high-temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low bio-coal yield at high pyrolysis temperatures.
