… macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2). The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol …
Naturskyddsföreningen gav författarna uppgiften att undersöka förekommande viskosprocesser och alternativa regenereringsprocesser, detta för att identifiera hur hållbara de är ur ett miljöperspektiv och vilka processer som går att applicera på bambu. Detta för att se möjligheten …

… deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a …
… diluted in ethylalcohol, was used there instead. This paper also investigates cellulose ethersthrough a review of literature concerning their stability for longterm use. In general, the celluloseethers used in conservation are stable for longterm use, even though there are …

… that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol. Tha amount of ethanols that is studied in this work is the smount …
Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium …

… attack conifers. Brown rot fungi mainly consumes the polysaccharides, i.e. cellulose and hemicellulose, while the brown lignin remains. Wood attacked by brown rot cracks in cubic pieces, and the fungi decreases the strength of the wood. Examples of fungi causing brown rot are …
… for ethanol production can be divided into three groups: suger, starch and cellulose. Biostil is a process developed in order to make ethanol production as cheap and environmentally friendly as possible. This method is used to manufacture both fuel and technichal ethanol. The …
… the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and …
… et.al. (2005) has shown that the reactivity of a dissolving pulp (the cellulose raw material) increased when it was pre-treated with endoglucanase (enzyme). Kvarnlöf (2007) also showed that the amount of carbon disulfide that is needed to produce an ordinary viscose (in this …
Individual cellulose ?bers were studied to identify the transport and absorbtion phenomena as well as the in?uence of drying. A Chalmers University of Technologydeveloped method within ESEM (Enviromental Scanning Electron Microscope) has been used in this study. The results from …
Om F.O.V. Fabrics möjligheter att understödja kommersialiseringen av algbatteriforskning
… aiming to commercialize a newly discovered technology ? a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own. This framework focuses on the environment defined by actor bonds to three …
En undersökning för att fastställa en rimlig inbyggnadsfuktkvoti träreglar med fuktsimuleringsprogrammet Wufi 2D
To save energy it’s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more …
… Domsjö Fabriker AB in Örnsköldsvik, who is converting softwood into special cellulose, bio-ethanol and lignin, are interested in pyrolysis technology. They are using the unique sulphide process; and during the pulping of the biomass a residue in form of knots are extracted from …
