1. 1. Implementation of an automatic tangential flow filtration system for latex immunoassay production

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Filippa Stolpe; Sofia Kullander; [2023]
   Keywords : biotechnology; bioprocess; diagnostics; production; TFF; tangential flow filtration; blood clots; automation; antibodies; latex immunoassay; LIA;

   Abstract : To diagnose patients suffering from blood clotting disorders latex immununoassays (LIA) can be used. A time consuming manual tangential flow filtration (TFF) process suggests the implementation of an automatic TFF system to improve the efficiency, profitability, and expandability of the production facility of LIA at Nordic Biomarker.

3. 2. Tribological behaviour of metal sulfides UHMWPE composites in dry lubrication

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Bruno Pizone Vaz; [2021]
   Keywords : Polymer composites; polymer tribology; dry lubrication; UHMWPE; metal sulfides; tribology;

   Abstract : The increasing worldwide demand for more eco-friendly materials with improved tribo- logical properties has expanded the interest in research on polymer as an alternative for conventional metal/metal contacts under dry lubrication. Specifically, UHMWPE, a semi-crystalline polymer, has shown interesting tribological properties for low demanding applications, allied with excellent recyclability, manufacturability and low cost.

4. 3. Plastic as marine debris and its potential for economic value : A practical and analytical estimation of the marine debris characteristics and a comparative evaluation of possible treatment procedures

   University essay from KTH/Industriell ekologi

   Author : Astrid Hartman; Ella Lovén; [2014]
   Keywords : ;

   Abstract : Every year around 270 million tonnes of plastic are produced worldwide. As a result of poor waste management in many countries, a large amount of it ends up in the world’s oceans where it degrades into micro particles. READ MORE

5. 4. Antisolvent Precipitation of L-Asparagine in a Commercial Micromixer

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Francesco Ferrante; [2012]
   Keywords : Crystallization; precipitation; micromixer; micro-particles; L-asparagine;

   Abstract : A commercial valve-assisted micromixer, manufactured by Ehrfeld (Germany), was tested for its use to precipitate L-asparagine from an aqueous solution using isopropanol as antisolvent. In a first part the mixing quality provided by the micromixer was studied by means of a competitive/parallel set of reactions following the approach of Baldyga, Bourne and Walker, Canadian J.

6. 5. Halfsphere Derivatisation of Magnetic Micro Particles

   University essay from Institutionen för biologi och kemiteknik; Akademin för hållbar samhälls- och teknikutveckling

   Author : Nadea Dilanson; [2008]
   Keywords : ;

   Abstract : Abstract   This exam project is an effort to derivatize one side of magnetic beads with one kind of molecule  , and another one on the opposite side. First the surface of the sphere is loaded with a suitable linker with, e.g. amino or hydroxyl groups. READ MORE
