Classification using proximity catch digraphs

Machine Learning - We employ random geometric digraphs to construct semi-parametric classifiers. These data-random digraphs belong to parameterized random digraph families called proximity catch...     

WC-based catalyst for isopropyl alcohol dehydration as prepared by combustion synthesis

WC-based catalyst was prepared by SHS method using highly exothermic WO₃ + Mg + C mixtures. Two kinds of tungsten oxide—commercially available and obtained by decomposition of the peroxo complex of tungsten oxide—were used as tungsten sources. To soften violent conditions of combustion, the well-known salt dilution method was applied. Tuning the reaction temperature by added NaCl and carbon afforded to regulate the composition of products. As a result, a submicron-sized WC/C material with an 11 m²/g specific surface area was produced. The latter was tested for the catalytic activity in isopropyl alcohol conversion. An 83% alcohol conversion into propylene and water with 100% selectivity was observed at ≈200°C.
