This tenth anniversary collection of RACI and Academy of Science Award papers starts with a contribution by Carol Hua (The University of Melbourne), the 2023 Alan Sargeson Lecture awardee of the RACI Inorganic Division. Together with co-workers Hui Min Tay and Shannon Thoonen, she reports on chiral 1-D coordination polymers containing bent 1,1′-binaphthyl ligands with dipyridyl or dicarboxylate substituents and coordinated with Ni II , Cu II or Ag I . Both linear and helical 1-D chains were identified. 1 Mary J. Garson (The University of Queensland) received a RACI Distinguished Fellowship. Together with co-workers L. C. Foster, G. K. Pierens and James J. De Voss, she describes the elucidation of new norditerpenes with a dendrillate scaffold isolated from the Australian nudibranch Goniobranchus coi. Interestingly, new rearranged spongian diterpenes contained perhydroazulene and dioxabicyclo[3.3.0]octane moieties were isolated and characterised. 2 Michael Kassiou (The University of Sydney) is the 2023 H. G. Smith Memorial Awardee. Together with co-workers C. Dana, G. A. Cumbers, B. Allen, A. P. Montgomery and J. J. Danon, he reports on the use of the adamantanoid motif in medicinal chemistry. Replacemenet of phenyl by adamantyl groups increases lipophilicity and facilitates a precise positioning of substituents. The increased lipophilicity improves the blood-brain barrier permeability and hence the central nervous system activity of adamantanoid drugs. 3 Christian G. Hartinger (University of Auckland) is the recipient of the 2023 Burrows Award of the RACI Inorganic Division. Together with co-workers S. Kumar, M. Riisom, D. M. F. Jamieson, T., Sohel, S. Bhargava and J. Sun in New Zealand, Australia and China, he reports on the synthesis of N-heterocyclic (N-methylimidazole, N-methylbenzimidazole and pyridine) ligands in so-called piano-stool complexes, i.e. analogues of the plecstatin-1 anticancer drug. The new complexes exhibited potent antiproliferative activity similar to plecstatin-1 in a small panel of cancer cell lines. 4 Adam Lee (Griffith University, Gold Coast) received a 2023 Welcome Award of the RACI. With co-workers P. Lokhande, P. L. Ghepe and K. Wilson, he contributes a paper on the aerobic oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid, which is of interest as a potential replacement of terephthalic acid in plastics manufacture. The reaction is catalysed by Ru on calcined MgO. Yields up to 68% at 94% conversion were obtained at 160°C and 1.5 MPa of O 2 . 5 D. Brynn Hibbert (University of New South Wales) received the 2023 Leighton Award of the RACI. He contributes a review on Bayesian approaches to applying an Australian electronic nose to identify an unknown odour out of a set of known odours. To do so, multivariate supervised learning is accomplished by applying Bayes' theorem to data from metal-oxide semiconductor sensors responding to target odours. An odour from an unknown source can then be assigned probabilities of belonging to each of the training sets. 6 Theo A. Ellingsen...
