  1. 1. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

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

    Author : Carl Pontén; [2024]
    Keywords : Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

    Abstract : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

    Keywords : ;

    Abstract : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. READ MORE

  5. 4. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

    University essay from

    Author : Christian Waldenberg; [2022-11-08]
    Keywords : Medical physics; Normoxic polymer gel dosimeter; NiPAM;

    Abstract : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. READ MORE

  6. 5. Activity and stability of urease enzyme molecules for on-site urea measurement in milk

    University essay from Linköpings universitet/Sensor- och aktuatorsystem
