  1. 16. Preparation and process optimization of encapsulating cellulose microspheres

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Sofia Abdi; [2015]
    Keywords : cellulose; microsphere; biopolymer; encapsulation; dispersing agent;

    Abstract : Microspheres are spherically shaped particles within the size range of 1-1000 μm in diameter. Due to the their small size and round shape, microspheres show many advantages in various applications such as pharmaceuticals, composites and coatings. READ MORE

  3. 17. Acid hydrolysation of starch and formulation of starch microspheres

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Zahrai Najeeb; [2015]
    Keywords : Starch acid hydrolyze; starch microspheres; Rheology; läkemedelsteknologi; pharmaceutical technology; Technology and Engineering;

    Abstract : The aim of this diploma work is to investigate the acid hydrolyses of two types of starch, waxy barley and maize starch to be applied for further usage, in rheology studies and formulation of starch microspheres. Modified starch has always been essential in many areas, especially in tablets, where it could be used as a disintegrant. READ MORE

  4. 18. Physiological ranges and variability in organ blood flow in laboratory animals

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Camilla Anger; [2014]
    Keywords : organblodflöden; laboratoriedjur; farmakokinetik; regionala blodflöden; scaling; fysiologiska parametrar; organ blood flow; cardiac output; laboratory animals; physiologically based pharmacokinetics; microspheres; physiological parameters;

    Abstract : BACKGROUND: Organ blood flow rates are useful in allometric scaling and for the application of Physiologically Based Pharmacokinetic Modeling (PBPK). These models are typically used for extrapolating pharmacokinetic data across different species, which has important applications in drug discovery and safety assessment. READ MORE

  5. 19. Development of an Expancel Product through Optimisation of Polymer Composition and the Suspension Stabilising System

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Frida Berggren; [2014]
    Keywords : microspheres; suspension polymerisation; Pickering emulsions; flocculation;

    Abstract : Thermally expandable microspheres are spherical particles around 5-­‐40 µm in size, consisting of a polymeric shell in which a blowing agent has been encapsulated. The microspheres are expanded upon heating, resulting in a particularly low density. Microspheres are therefore suitable to use as light weight filler or as foaming agent. READ MORE

  6. 20. Optical and Mechanical Properties of Cool Roof Paint Containing Hollow Thermoplastic Microspheres

    University essay from Institutionen för kemi - Ångström

    Author : Olof Sandin; [2013]
    Keywords : ;

    Abstract : This master thesis examines the effect of hollow thermoplastic microspheres in coolroof paints. These types of paints are characterized by their high reflectivity forwavelengths up to 2.5 micrometers and high absorptivity in the IR region. Thethermoplastic microspheres were produced by Expancel®, a unit withinAkzoNobel®. READ MORE
