uk prime minister rishi sunak arrived a short while ago. he was greeted by moldovan president maia sandu. and once all of the more than a0 leaders of countries and various organisations had all made it to the venue, mimi castle, they posed for what s known as the family photo. but as you d expect, with plenty to talk about, they didn t stand still for long. you may have seen ukraine s president volodymyr zelensky there standing out through his choice of military fatigues over a suit. he was among the first to arrive earlier this morning and he was also given the first opportunity to address the gathering, warning that russia is an aggressor and needs to be stopped. he said that apart from peace there are only two options for countries which are not in the eu and nato war or russian occupation. every european country that borders russia and that does not want russia to tell them apart should be a former member of the eu and nato. there are only two alternatives to these,
size determines their properties. alexey ekimov, moungi bawendi and louis brus discovered and developed this artificially created collection of semiconducting nanoparticles. they are just a few millionths of a millimetre wide and glow blue, red or green when exposed to light. quantum dots already have commercial and scientific uses and, in future, could contribute to flexible electronics, thinner solar cells and encrypted quantum communication. so, moungi bawendi, erm, i don t know, viewers may be watching this programme on qled tv one of the things that have arisen from the work that you ve done so just tell us about how your work collectively can be used to improve lives. so, qleds is one of the biggest moneymaking applications of quantum dots but the field, in the last few decades, has grown enormously and there s a lot of people working on many other potential applications that have yet to see either commercial success or the applications being proven, and that includ
of sweden and prince daniel, as well as students from here in sweden. welcome to nobel minds and the second of our two programmes. laureates, this is the first time that some of you have been brought together in discussion on television. congratulations to you all. thank you. applause. first, let s look at the chemistry prize with its scientific breakthroughs that have myriad uses that will benefit humankind. let s have a short video looking at what the prize for chemistry was made for. it s very strange. the nano world is really, really bizarre. when matter is reduced to its smallest dimensions, it s made up of quantum dots nanoparticles so tiny that their size determines their properties. alexey ekimov, moungi bawendi and louis brus discovered and developed this artificially created collection of semiconducting nanoparticles. they are just a few millionths of a millimetre wide and glow blue, red or green when exposed to light. quantum dots already have commercial and scie
