Following last year's success, the MSDG Christmas Meeting will come again to 15Hatfield. Research Meetings organised by the MSDG are interesting, informal and inspiring. The Summer Meetings are usually two to three days, and the Christmas Meetings are always a one-day event in London. As in recent years, the 2009 MSDG Christmas Meeting will accept papers in all areas of the science and technology of high and room temperature liquid salts. Authors are required to submit an abstract prior to the meeting, to be bound and distributed to attendees.
