| 3 | Visualization of atomic scale reaction dynamics of supported nanocatalysts during oxidation and ammonia synthesis using in-situ environmental(scanning) transmission electron microscopy显示文摘Reaction dynamics in gases at operating temperatures at the atomic level are the basis of heterogeneous gas-solid catalyst reactions and are crucial to the catalyst function.Supported noble metal nanocatalysts such as platinum are of interest in fuel cells and as diesel oxidation catalysts for pollution control,and practical ruthenium nanocatalysts are explored for ammonia synthesis.Graphite and graphitic carbons are of interest as supports for the nanocatalysts.Despite considerable literature on the catalytic processes on graphite and graphitic supports,reaction dynamics of the nanocatalysts on the supports in different reactive gas environments and operating temperatures at the single atom level are not well understood.Here we present real time in-situ observations and analyses of reaction dynamics of Pt in oxidation,and practical Ru nanocatalysts in ammonia synthesis,on graphite and related supports under controlled reaction environments using a novel in-situ environmental(scanning) transmission electron microscope with single atom resolution.By recording snapshots of the reaction dynamics,the behaviour of the catalysts is imaged.The images reveal single metal atoms,clusters of a few atoms on the graphitic supports and the support function.These all play key roles in the mobility,sintering and growth of the catalysts.The experimental findings provide new structural insights into atomic scale reaction dynamics,morphology and stability of the nanocatalysts. | Michael R.Ward Robert W.Mitchell Edward D.Boyes Pratibha L.Gai | 2021 | Journal of Energy Chemistry2021，30，6： | 0 |
| 4 | Myxomycetes from Papua New Guinea and New Caledonia显示文摘We present a compilation of all myxomycetes recorded from Papua New Guinea(PNG)and New Caledonia(NC).Specimens were collected during field trips in September 1983–January 1984 to both territories and in August 1991,October 2007,and April 2009 to NC.Bark and dung samples for moist chamber cultures were collected during the field trips in September 1983–January 1984(PNG and NC)and in August 1991 and October 2007(NC).In addition,information from previous publications and unpublished specimens in the herbarium at the Plant Protection Instituted in Port Moresby,PNG,are included.A total of 180 species are reported.Of the 63 species from PNG 51 are new to the country,and 123 of the 149 species from NC are new to the territory. | Henrik Kylin David W.Mitchell El-Hacène Seraoui Bart Buyck | 2013 | Fungal Diversity2013，，2： | 0 |
