Bergström, Lennart

Background

I recieved my PhD in Physical Chemistry from KTH in 1992 while working in parallel as first project manager and then section manager at the Institute for Surface Chemistry, YKI. I was visiting scientist at University of Washington, USA in 1990 and post doc at Tokyo Institute of Technology, Japan in 1994.  In 2004 I was appointed professor in materials chemistry at Stockholm University.

Research

Self-assembly of nanoparticles  and novel process routes for nanocrystals and other inorganic colloids to form novel nanostructured materials with useful properties are at the core of our activities where the fundamental activities aim to generate a better understanding of the molecular or mesoscopic assembly mechanisms. Biomimetic synthesis which involves the integration, directed assembly and controlled crystallization of inorganic materials with polymers and biomolecules is another closely related field of interest. This quest has lead us to explore traditional methods to treat fibres from renewable resources. Colloidal processing of ceramics was an important part of my previous work at the Institute for Surface Chemistry, YKI and we are now  developing novel methods to produce hierarchically porous materials for e.g. gas separation applications.
