1. On guided bone regeneration using ceramic membranes
Abstract : Regeneration of bone in the oral and maxillofacial region can beachieved with different techniques such as autologous bone grafts,bone substitutes and guided bone regeneration. Guided boneregeneration is defined as creating a space between the bone and itssurrounding tissues, using a barrier that allows new bone to migrateinto the space while preventing other cell types from interfering.

2. Crossflow Microfiltration of particle Suspensions - The influence of hydrodynamics and physico-chemical interactions
Abstract : Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. READ MORE

3. Adsorption and Mass Transport in Zeolite Membranes
Abstract : Zeolites are commonly used as adsorbents and catalysts in the industry due to their well-defined pores of molecular dimensions. Zeolites offer porous structure, which consists of interlinked alumina and silica tetrahedra with shared oxygen atoms. READ MORE

4. Development of permporometry for analysis of MFI membranes
Abstract : Zeolite membranes exhibiting high flux and high selectivity are of major interest for potential future applications. In order to achieve high flux and high selectivity, the zeolite film must be thin (< 1 µm) and free from flow-through defects. READ MORE

5. Extraction of Lignin from Kraft Cooking Liquor by Ultrafiltration
Abstract : Lignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. READ MORE
