In this paper we highlight the important contribution made by Bob Madix to the understanding of catalysis at single crystal surfaces, focusing here on a favourite model system of his, namely the oxidation of methanol on Cu(110). Madix showed clearly that the methoxy was the pivotal intermediate involved, and it is bound to the surface through the oxygen atom. Here we demonstrate the nature of t...

Elementary cellular automaton (ECA) rules 9 and 74, members of Chua’s Bernoulli shift rules and Wolfram’s class 2, can generate a host of gliders and complicated glider collisions by introducing the hybrid mechanism. These gliders and collisions are more plentiful than those generated by ECA rule 110. This paper presents a discussion of the symbolic dynamics of the gliders in hybrid cellular au...

Meteoritical Bulletin 110 contains the 2802 meteorites approved by Nomenclature Committee of Society in 2021. It includes 10 falls (Arpu Kuilpu, Djadjarm, Glendale, Kindberg, Madura Cave, Motopi Pan, Orconuma, Punggur, Tihigrin, Winchcombe), with 2014 ordinary chondrites (including 1 ungrouped chondrite), 220 carbonaceous 11 ungrouped), 212 HED achondrites, 69 lunar meteorites, 62 ureilites, 43...
