What is it about?
Discovery of low temperature (80 deg.C) coalescence of nanocrystalline Pt in NO atmosphere. Proposition of its mechanism via turbulent, self-lifting surface reconstruction. Supported by results from novel, PXRD based technique focused on nano-surface phenomena.

Why is it important?
- It may be significant for catalysis explaining origin of quick sintering in reactions involving NO e.g. nitric acid synthesis or NO reduction on car exhaust catalyst. - It shows possibilities of a proposed by us novel, PXRD based technique to observe in situ and distinguish nanometal surface relaxation and reconstruction phenomena
