A05 Handling acetylene IGS-TS-A05-16-e Page 3 of 4 Physical properties Relative density Acetylene has a relative density of 0 91, making it approximately 10 lighter than air This means that acetylene easily spreads upwards in the ambient atmosphere Work areas in which acetylene is han-
Carbagas) Catalyst preparation Molybdenum nitrides were synthesised by tempera-ture-programmed reduction–nitridation according to a previously published procedure [7, 8, 10]; the preparation steps are shown in Fig 1 MoO 3 (0 15 g, 99 9995 w/w, Alfa Aesar, 1 m2 g-1) was placed in a horizontally mounted quartz reactor (12 mm i d ),

carbon nanotubes using chemical vapor deposition of acetylene Our results show that the choice of the catalyst is of extreme importance Most of the aqueous and ethanolic Fe(III) inks used give rise to drying effects on the stamp surface, which lead to the formation of islands of the catalyst within the pattern To
