Highly monodisperse size-controlled silica particles from 50 to over 1000nm bearing thiol, vinyl, phenyl, propyl, cyanopropyl and chloropropyl R group functionality were synthesised directly from the corresponding single organosilane source. Observing particle growth over time revealed that it proceeded by a conventional Stöber process, where silane monomers and oligomers add to nucleation sites, resulting in particle growth. Scale-up of the homogeneous mixing approach produced gram quantities of particles without affecting size, size dispersion or functionality under good mixing. The presence and functionality of the surface R groups were confirmed by a simple second addition of reactive molecules to the particle synthesis liquor, resulting in theoretical maximum attachment densities.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135058635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were developed by Prof. Brian Yates and Prof. Sue Jones, supported by Dr Jo-Anne Kelder, during 2010–2011. The co-authors of this paper are key figures in Australian Science education, and in this manuscript, we have used a reflective semi-structured interview approach to describe the process of developing the Science TLOs and consider their subsequent effect on tertiary science education in Australia. This manuscript documents Sue and Brian’s impact on science curriculum through the lenses of leadership, community and practice. We have a twofold aim: first to draw lessons for harnessing consensus in scientific communities on the value and purpose of a tertiary science education, and second to celebrate the success of these influential and impactful leaders in our community. We demonstrate how work to develop the TLOs has transformed tertiary science education in Australia.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135360516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manipulation of these adducts then afforded a series of derivatives. So, for example, reductions of the associated carbonyl groups delivered the corresponding alcohols including compound 29 and on reaction of these with diethylaminosulfur trifluoride rearranged fluorination products such as tetracycle 30 were obtained. An analogous suite of compounds was obtained by manipulation of the Diels–Alder adducts derived from reacting the same dienes with iso-levoglucosenone that was itself obtained through simple manipulation of levoglucosenone. Our earlier studies suggest that various of these derivatives could be used in the production, via ring-opening metathesis polymerisation (ROMP), of new bio-based polymers.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136052490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Craik","doi":"10.1071/ch23155","DOIUrl":"https://doi.org/10.1071/ch23155","url":null,"abstract":"A specimen of the marine cone snail Conus victoriae collected from a beach in Broome, Western Australia, by a group from The University of Melbourne led to the discovery of the α-conotoxin Vc1.1, which was found to have analgesic activity in rodents. The discovery of this venom-derived peptide led to a series of structural, mechanistic and pharmacological studies directed towards the development of a new analgesic for neuropathic pain by groups in Australia and internationally. Solid-phase peptide synthesis played an important role in developing structure–activity relationships. Studies in a rat model of neuropathic pain showed that a cyclic analogue of the peptide, cVc1.1, had comparable analgesic activity with that of gabapentin, one of the foremost clinically used drugs for neuropathic pain, with cVc1.1 delivered orally at a 120-fold lower dose than gabapentin. Originally, Vc1.1 was believed to act primarily through nicotinic acetylcholine receptors, but evidence for a mechanism mediated through γ-aminobutyric acid B (GABAB) receptors later emerged. Efforts to optimise the binding and pharmacological properties of analogues of Vc1.1 revealed that the affinity towards either receptor can be modulated by sequence mutations, disulfide bond modifications and backbone cyclisation. This Account describes the discovery, structure, chemistry and pharmacology of Vc1.1, with a focus on studies carried out in Australian laboratories.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135953869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
