ISMSC-2020 will provide a forum for the discussion of all aspects of macrocyclic and supramolecular chemistry, including nanoscience and materials science. It will follow the style of the preceding meetings in the series with a single scientific session running throughout the conference. ISMSC, the International Symposium on Macrocyclic and Supramolecular Chemistry, came from a fusion of the International Symposium on Macrocyclic Chemistry (ISMC) and the International Symposium on Supramolecular Chemistry (ISSC). These meetings combined in 2006 and since then have been held on an annual basis in a different location. Join us for the meeting in Sydney in 2020! https://www.ismsc2020.org/home Contents Volume 83, No.3, July 2019 Articles and features 104 Subtleties and complexities: some musings on teaching first year chemistry Allan Blackman 108 Towards functional surfaces using Langmuir-Blodgett deposition techniques Alex T.

All of the interviews are available on the Radio NZ website in the Nights section.

We recently launched our flagshipIYPT2019 competition for schools and school-age children. To celebrate the In- ternational Year of the Periodic Table the NZIC and the Royal Society of Chemistry New Zealand Branch are run- ning an exciting video competition. Entries will be in the form of a 1-2 min video about a favourite element from the periodic table. There are 118 elements to choose from, so we hope that there will be lots of diversity in the entries! There are two judging categories: Junior/In- termediate School (Years 1-8) and Senior School (Years 9-13). Individual and group/team/class entries are both Another conference looming on the horizon is Paci- welcome.

Sarah Masters NZIC President Editor’s note The April 2019 issue of Chemistry in New Zealand included an obituary for Professor Brian Halton. Doug Wright, a former NZIC President, has brought to our attention that NZIC was involved with Pacifichem well before Brian’s con- tributions began in 1990. Doug was the NZIC delegate at the inaugural organising meeting of Pacifichem in the early 1980s. This meeting of the organising bodies was held in Tokyo and included delegates from USA, Canada, Japan, Australia and Malaysia. 94 Chemistry in New Zealand July 2019 News New Zealand Institute of Chemistry supporting chemical sciences July News AUCKLAND Simcock.

Chemistry Olympiad Training During the week of 15 April, The School of Chemical Sciences hosted a training week for the Chemistry Olympiad. The students (32 in total, 14 from outside Auckland) received lectures and training in laboratory skills by a team that included Asso- ciate Professor Duncan McGillivray, Katrina Graaf, and Dr Sheila Wood- gate, together with teachers from the Auckland area and Associate Professor Owen Curnow from the University of Canterbury.
