  2. 16. Asymmetrical Flow Field-Flow Fractionation in the Separation, Characterization and Application of Wine Particle Matter

    Author : Daniel Osorio Macias; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AF4-UV-MALS-dRI; wine colloids; wine macromolecules; phenolic compounds; polysaccharides; winemaking;

    Abstract : Wine particle matter is mainly constituted by wine colloids and wine macromolecules. These wine colloidal and macromolecular compounds are barely studied, possibly due to the difficulty in facing the challenges that their study merits. READ MORE

  4. 17. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Author : Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. READ MORE

    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

  7. 20. Models for the Transfer of Drugs from the Nasal Cavity to the Central Nervous System

    Author : Björn Jansson; Erik Björk; Sveinbjörn Gizurarson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Administration; intranasal; Nasal mucosa; Central nervous system; Olfactory bulb; Rat; Mouse; Swine; Cattle; Diffusion chambers; culture; In vitro; Biological models; Biological transport; Dextrans; Dopamine; Gels; Polysaccharides; Autoradiography; Fluorescence microscopy; Biofarmaci; Biopharmacy; Biofarmaci;

    Abstract : The blood-brain barrier restricts the access of many compounds, including therapeutic agents, to the brain. Several human studies indicate that nasal administration of hydrophilic compounds, such as peptides, can bypass the blood-brain barrier. The aims of this thesis were to develop and refine models for this direct nose-to-brain transfer. READ MORE
