Latest Patents

One of Bernt Larsson's notable inventions is a method for the preparation of silica particles. These silica particles are characterized by their substantial spherical shape, a particle size ranging from 1 to 100 micrometers, very narrow pore size distribution, and low alkali metal content. Utilizing a sol-gel technique combined with an emulsification technique for drop formation, this process involves a sol growth stage in a basic environment, employing ammonium or amines, followed by a specialized post-treatment in such an environment. The resulting silica particles possess exceptional properties that enhance their suitability for applications in chromatography due to their excellent particle and porosity characteristics along with high purity.

Another significant patent from Larsson is focused on a novel papermaking process. In this innovative method of creating paper or pulp sheets from paper stock, a unique binder is introduced that combines cationic and anionic components to improve both paper and stock characteristics. This blend results in increased retention and facilitates a more readily dewatered stock. The anionic component features colloidal particles with a surface layer of aluminum silicate or aluminum-modified silicic acid, while the cationic component includes a carbohydrate with a degree of substitution between 0.01 and 1.0. This innovation plays a pivotal role in enhancing the overall quality and efficiency of the papermaking process.
