The purpose of this proposed project is to suggest new pathways for the adsorption reactions to cellulose fibers in the bleaching step in the kraft pulp process. The long-term aim is to develop a flexible knowledge platform that can be used for designing functionalized surfaces of the cellulose fibers in the bleaching step, using by […]
Projektets mål är karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall. Sådana är praktiskta viktiga vid konvertering av kartong i allmänhet, men speciellt betydelsefulla vid 3D-formning av geometriskt avancerade strukturer. För att nå målet ska experimentella 4D datortomografiundersökningar kombineras med matematisk modellering.
The use of wood and wood based materials in moist environments is limited because of these material’s susceptibility to decay fungi. The durability thus needs to be improved, which can be achieved by chemical wood modification. The exact mechanisms behind the increased durability of modified wood is however not known, but the lowered moisture content is

Modern methods to protect wood from degradation aims at increasing the service life of the material by removing or reducing the cause of degradation: water within the material. This can be done by wood modification, e.g. acetylation or heat treatment. However, there is a lack of understanding of what happens within the wood, which hampers

Rheometry explores the relationship between forces and motion through (continuum) constitutive relations and suitably defined material functionsi. Rheometry is important for soft matter from two main reasonsii: (i) to investigate correlations between molecular structure and material behavior and (ii) to attempt the prediction of flow behavior in complex situations using material parameters determined in simple,

My group at Stockholm University will be developing new materials from renewable resources such as lignin and other components of plant biomass. A central focus area will be the utilisation of green chemistry principles en route to functional materials for energy and environmental applications. We will be seeking close collaboration with the industry and the

In this project, the purpose is to implement solid-state NMR methods to obtain domain sizes in biopolymer composites and to determine molecular orientation distribution in anisotropic material. The ambition is to take advantage of recent methodological NMR development regarding spin diffusion and intrinsic chemical shielding tensor properties. The project is a part of WWSC

Even though aqueous alkaline systems are among the most prominent and sustainable conversion media for cellulose (of particular importance for large scale processes) fundamental understanding of principal molecular interactions in these systems is still limited, especially of those stabilizing cellulose solutions in aqueous alkali. However, regardless of the nature of stabilizing interactions in these solutions,

Syftet med detta projekt är att förbättra hållbarheten utomhus av trä och biokompositmaterial för fasadmaterial samt utemöbler med hjälp av robust ytmodifiering som avvisar vatten, oljor och smuts. Vår nya idé bygger på användning av hållbara komponenter och skalbara processer. Vetenskapliga och tekniska mål är att formulera en halvtransparent beläggning för trä för att skydda
The plant cell wall is a highly complex structure, and the main constituent of wood as a material. Microorganisms can break down essentially all parts of the cell wall with time, and their enzymatic strategies can today be utilized thanks to the advances in molecular biology and biochemistry. The enzymes can be used as highly
Treesearch har som syfte att skapa en nationell plattform för att stödja forskning. Forskningsprojekt som bedrivs inom Treesearch forskningsområden och de forskare som är aktiva i dessa projekt är välkomna att ansluta till plattformen.
