Eucalypts essential oils

2023-10-10 / Luis

These days I deal mostly with quantitative genetics and wood properties. However, trees are much more than wood and one of our PhD students at the School of Forestry, University of Canterbury had a look at production of Eucalypts essential oils, particularly cineole.

One can easily see the seasonality of production (peak in Spring & Summer) and the difference between juvenile and mature foliage. Details available at:

Chamira Rajapaksha, Luis A. Apiolaza, Marie A. Squire and Clemens Altaner. 2023. Seasonal variation of yield and composition in extracts from immature and mature Eucalyptus bosistoana leaves. Flavour and Fragrance Journal 38(4): 293-300. Open Access at https://doi.org/10.1002/ffj.3742

Seasonality for cineole and total oil, plotted by family and leaf type.

Radioactive sessions

2023-06-18 / Luis

Sessions last an hour, in which I have to link to something, chain my mind so it doesn’t float away and go to dark places. Music is the easiest anchor; each session I hand-in a piece of paper with the name of an album which becomes the centre of my universe. They search it in Spotify and comes up on the headphones, covering the noise of particles.

Session 1: Vrioon by Alva Noto & Ryuichi Sakamoto

Session 2: Familiar Places by Little North

Session 3: Finding Seagulls by Little North

Session 4: The Blue Notebooks by Max Richter

Session 5: Viaje por la Cresta del Mundo by Congreso. In my opinion, this is the best Chilean album of the last 50 years.

Session 6: Familiar Places by Little North. Top-up session, so I allowed myself a repeat.
