This 12 months’s Nobel Prize in Chemistry acknowledges a milestone for your complete nanotechnology area.
It went kind of like this on 4 October. In a moderately unassuming assembly room we sat with different chemistry editors to observe the announcement of the Royal Swedish Academy of Sciences; cookies offered. The principal candidates for the prize, who had been the topic of a lot hypothesis in chemistry magazines and on social media within the days main as much as the occasion, formed the sitting sample: natural chemists in a single nook; electrocatalysis fans within the different; the poor bodily chemists considerably misplaced within the center. As 11 am approached, smartphones had been refreshed with a frequency rivalling that of an NMR, getting dangerously sizzling. There have been already robust rumours that the prize can be about quantum dots, however that was all forgotten when the Committee, sitting within the press convention room, appeared on the display screen. Silence. The techy ones set their translation apps from Swedish to English to counter the custom of creating the announcement first in a language spoken by a hint quantity of scientists (however crucially by our Alfred, the one with the cash).

Then every little thing modified. “This 12 months’s prize is a few elementary discovery in nanotechnology” (https://youtu.be/6ilqb5qlI8s). A candy music began taking part in in our ‘nano’-editor brains, our faces smiling like when an experiment works, after which even the Committee on the display screen joined in, displaying vibrant options: so stunning, so fluorescent, like a synaesthetic expertise; it was nearly an excessive amount of to take… and we thought these had been simply cookies!
Only some minutes later, again from this intense expertise, we began realizing the magnitude of what had simply occurred. A chemistry Nobel Prize to elementary nanotechnology just isn’t one thing strange. There have been different nanotechnology Nobel Prizes (the C60, graphene, molecular machines, for instance), to make certain, however this by some means felt extra particular. And certainly it’s, as a result of it was awarded to the commentary of a phenomenon by which matter exhibits completely different properties relying on measurement — a foundational idea for your complete area of nanoscience and nanotechnology, not only for quantum dots. The attraction for nanotechnology stems partly from the truth that it presents comparatively easy chemical instruments (measurement, form, floor chemistry) to regulate the construction–property relationship of a fabric in a exact means, one thing you don’t have within the bulk or in molecules.
We refer you to the Nobel Committee for Chemistry publication1 and to a current evaluation article2 for an in depth historical past of the invention of quantum dots and the position of the awardees: Moungi G. Bawendi, Louis E. Brus and Aleksey Yekimov. On this challenge, we’re delighted to supply readers a Q&A with Prof. Brus given just some days after the prize was awarded.
He remembers the early days of his encounter with colloidal quantum dots within the 1982–1986 stretch throughout his interval at Bell Labs, the place the commentary of a shift over time within the optical absorption peak of cadmium sulfide small crystals crucially captured his scientific curiosity. As well as, Prof. Brus, now emeritus at Columbia College, presents an necessary piece of recommendation to younger scientists that’s price re-emphasizing right here, as a result of it encapsulates the scientific strategy that has made nanotechnology the success that it’s. He displays on the truth that we’re all restricted by our scientific background, and that it could possibly typically be a ceiling in a scientist’s profession as a result of it prevents them from taking a look at an issue from completely different factors of view. Getting out of the hyper-specialized worlds which scientists typically discover themselves sucked into requires vitality, self-questioning and a very good dose of braveness. Prof. Brus’s sensible recommendation is to take the time to learn papers exterior the quick area of 1’s specialization; ask colleagues why they’re engaged on a given downside: what do they discover so thrilling about it? what drives them?; and at all times search for a greater downside to resolve.
As nanoscience and nanotechnology fans, we all know that an interdisciplinary strategy to scientific analysis requires overcoming the preliminary hurdle of defining, amongst different issues, terminology, investigative instruments and expectations. However we additionally know that bridging that interdisciplinary divide brings worth and accelerates discovery, in addition to being an enriching expertise.
Because of this, along with being a prize “for the invention and synthesis of quantum dots”, we interpret the choice of the Swedish Academy as a prize to the entire area of nanoscience and nanotechnology. Perhaps that’s why we skilled that second of numbness and elation on the announcement.
