Synopses & Reviews
The last ten years have seen a revolution in our understanding of the mechanisms of biological crystal growth. While it had long been assumed that crystallisation would occur by the same classical mechanisms which form the basis for most descriptions of crystallisation processes, it is now becoming apparent that this is not the case. This conference aims to bring together researchers working in the areas of biomineralisation, biomimetic crystallisation, nucleation and crystal growth. Themes of the discussion include biological crystallisation mechanisms, current ideas in nucleation, amorphous precursor phases, self-assembly crystal growth mechanisms. Although there is significant overlap between these disciplines in topic, researchers in these areas tend to remain distinct. There will be a huge benefit to readers of this new volume to learn by the discussion of similar problems from different perspectives, thus achieving a balance between experimentalists and theoreticians/ modellers.
The Scientific Committee warmly invites you to take part in this thought-provoking Discussion and looks forward to welcoming you to Leeds.
About the Author
Faraday Discussions documents a long-established series of Faraday Discussion meetings which provide a unique international forum for the exchange of views and newly acquired results in developing areas of physical chemistry, biophysical chemistry and chemical physics. The papers presented are published in the Faraday Discussion volume together with a record of the discussion contributions made at the meeting. Faraday Discussions therefore provide an important record of current international knowledge and views in the field concerned. The latest (2010) impact factor of Faraday Discussions is 4.5
