is scheduled for June 2- 7, 2013.
There is good reason to visit the URL listed above, beyond the obvious one of
finding out how to register for the event.
The site has a multitude of very informative extended abstracts (https://nam.confex.com/nam/2013/webprogram/),

Introduction
Transition metal phosphides show excellent promise for hydrotreating reactions
and the most active phosphides, Ni2P and Ni-rich bimetallic phosphides, have
exhibited higher HDS and HDN activities than commercial sulfided Co-Mo and
Ni-Mo catalysts [1,2]. Oxide-supported metal phosphide catalysts are most often
prepared by temperature-programmed reduction (TPR), in which phosphate-like
precursors are heated in flowing hydrogen to a maximum temperature in the range
823-923 K. TPR methods do not enable size and shape control of the degree
needed to probe microstructure-reactivity relationships in transition metal
phosphides. In this study, the preparation, characterization and
hydrodesulfurization (HDS) properties of mesoporous silica encapsulated metal
phosphide nanoparticles (Ni2P, Pd5P2) having narrow polydispersity were
investigated.
Significance
Encapsulation of metal phosphide nanoparticles to form core-shell
structures (e.g. Ni2P@mSiO2) minimizes sintering of the nanoparticles and
enables probing of the microstructural properties of metal phosphide catalysts
under the harsh reaction conditions relevant to industrial hydrotreating
processes
