  1. 1. Ultrastructure of the Primary Cell Wall of Softwood Fibres Studied using Dynamic FT-IR Spectroscopy

    Author : Jasna Stevanic Srndovic; Lars Wågberg; Per M. Claesson; Paul Gatenholm; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; primary cell wall; polymer interactions; viscoelasticity; dynamic FT-IR spectroscopy; dynamic 2D FT-IR spectroscopy; cellulose; xyloglucan; pectin; protein; lignin; low degree sulphonation; cellulose allomorphs; Wood fibre and forest products; Träfiber- och virkeslära;

    Abstract : The primary cell wall is a complex multipolymer system whose composite structure has been mostly determined from chemical and biochemical studies. Although the primary cell wall serves a central role, with regard to the connective properties of fibres, knowledge about the interactions among the polymers, when it comes to the mechanical properties, is very limited.

    Abstract : Obesity is a medical condition in which excess body fat has been accumulated. It is most commonly caused by imbalance between energy intake and energy expenditure (lack of physical activity and lower metabolic rate, etc.). READ MORE

  4. 4. Solid state characterisation and compaction behaviour of pharmaceutical materials

    Author : Christina Gustafsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Solid-state; Tablet; Thermal analysis; Cellulose; Spectroscopy; NMR; NIR; FT-IR; Crystallinity; MVDA; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : In this thesis, factors important in tableting operations and for tablet properties have been studied and characterised by different spectroscopic techniques as well as by some more conventionally used particle characterisation techniques. The spectroscopic techniques solid-state NMR, FT-IR and NIR spectroscopy, proved to be valuable tools in the estimation of particle and tablet properties, offering both specificity and sensitivity in the measurements.
