   Sammanfattning : Organic electronics is a hot and modern topic which holds great promise for present and future applications. One such application is the light-emitting electrochemical cell (LEC). It can be fully solution processed and driven at low voltage providing light emission from a large surface. LÄS MER

3. 2. Purification of psychoactive biomolecules in plants using size exclusion chromatography

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Ludwig Ring; [2009]
   Nyckelord :Size exclusion chromatography; Psychoactive; Drug; Plant; Gel permeation chromatography; Gel filtration chromatography;

   Sammanfattning : Size exclusion chromatography (SEC) was applied for purification of psychoactive biomolecules from plants. These molecules are in the same molecular weight range, but do not necessarily share other chemical properties, that makes the SEC technique efficient. LÄS MER
