The SNAKDD 2008 is the second in a successful series of workshops on social network mining and analysis. It solicited papers on broad overview subject "Social Network Mining and Analysis". The workshop drew a large number of participants from academia and industry. In this report we reflect on the results of the workshop, as captured in the regular paper session as well as the poster session.

A series of carbons was produced from mixtures of poly(ethylene glycol) and poly(furfuryl alcohol) with 25, 50 and 75% composition by weight and an Mn of 300 to18 500 g/mol of template.

This is interesting because PFA-derived carbon is well known to be non-graphitizing, meaning that it does not tend to crystallize even at very high temperature (>2500 °C). However, it has been demonstrated that after an oxidation with carbon dioxide, the PFA-NPC will crystallize at lower temperatures. Here, we show that localized crystallization of non-crystalline carbon takes place in the presence of each of the alkali metals, except lithium, under apparently mild conditions. At the local level, as adduced by HRTEM and electron diffraction analyses, cesium showed the greatest extent of ordering when compared to other alkali metals. However, when the materials are probed with bulk analyses, (X-ray diffraction, Raman spectroscopy, and NEXAFS), we do not observe evidence of gross crystallization. Therefore, it is our conclusion that local ordering occurs upon exposure of the alkali-containing PFA-NPC samples to air and that it occurs at the edges of the carbon particles. The ordering takes place as the alkali metals combust. We also conclude that carbons do not combust because the rate of oxygen transport into the sample is slowed by resistance in the nanopores as well as the resistance induced by the temperature gradient at the near surface region. Both phenomena prevent the gross combustion of the particle.

Reaction of Li2[Me2C(L)(C2B10H10)] (L = C5H4, C9H6, Me2NCH2CH2C5H3) with MCl2(PPh3)2 in Et2O afforded [η5:σ-Me2C(C5H4)(C2B10H10)]M(PPh3) (M = Co (4), Ni (5)), [η5:σ-Me2C(C9H6)(C2B10H10)]M(PPh3) (M = Co (6), Ni (7)), and [η5:σ-Me2C(Me2NCH2CH2C5H3)(C2B10H10)]Ni(PPh3) (8). Treatment of 4 or 5 with 2,6-dimethylphenylisocyanide, N-heterocyclic carbene (NHC), PCy3, or 1,2-bis(diphenylphosphino)ethane (dppe) gave the corresponding PPh3 displacement complexes [η5:σ-Me2C(C5H4)(C2B10H10)]M(2,6-Me2C6H3NC) (M = Co (9), Ni (10)), [η5:σ-Me2C(C5H4)(C2B10H10)]M[1,3-(2,6-i-Pr2C6H3)2C3N2H2] (M = Co (11), Ni (12)), [η5:σ-Me2C(C5H4)(C2B10H10)]Ni(PCy3) (13), or {[η5:σ-Me2C(C5H4)(C2B10H10)]Co}2(dppe) (14), respectively. These complexes were characterized by various spectroscopic techniques and elemental analyses. The molecular structures of 4–14 were further co...

Here we demonstrate that porosity of carbide-derived carbons (CDCs) can be tuned with sub-Å accuracy in a wide range by controlling the chlorination temperature. CDCs have narrow pore size distributions, comparable to zeolites and much narrower than single-wall carbon nanotubes or activated carbons. Furthermore,
