The Nobel Prize for Chemistry has been awarded to Moungi Bawendi, Louis Brus and Alexei Ekimov.
Hans Ellegren, secretary general of the Royal Swedish Academy of Sciences, said this year's prize was about their discovery in nanotechnology.
“The Nobel Prize in Chemistry 2023 rewards the discovery and development of quantum dots, nanoparticles so tiny that their size determines their properties,” he said.
“These smallest components of nanotechnology now spread their light from televisions and LED lamps, and can also guide surgeons when they remove tumour tissue, among many other things.”
The judges said the laureates have all been “pioneers in the exploration of the nanoworld”.
“Everyone who studies chemistry learns that an element’s properties are governed by how many electrons it has. However, when matter shrinks to nano-dimensions quantum phenomena arise; these are governed by the size of the matter,” the judges said.
“The Nobel Laureates in Chemistry 2023 have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology.
“Physicists had long known that in theory, size-dependent quantum effects could arise in nanoparticles, but at that time it was almost impossible to sculpt in nano dimensions. Therefore, few people believed that this knowledge would be put to practical use.”
In the early 1980s, Professor Ekimov, who works for Nanocrystals Technology, first succeeded in creating size-dependent quantum effects in coloured glass.
The colour came from nanoparticles of copper chloride and he was able to demonstrate that the particle size affected the colour of the glass via quantum effects.
A few years later, Professor Brus, professor emeritus at Columbia University, was the first scientist in the world to prove size-dependent quantum effects in particles floating freely in a fluid.
In 1993, Professor Bawendi, a professor at the Massachusetts Institute of Technology, revolutionised the chemical production of quantum dots, resulting in almost perfect particles. This high quality was necessary for them to be utilised in applications.
Quantum dots now illuminate computer monitors and television screens based on QLED technology. They also add nuance to the light of some LED lamps. Biochemists and doctors use them to map biological tissue.
“Quantum dots are thus bringing the greatest benefit to humankind,” the judges said.
“Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication – so we have just started exploring the potential of these tiny particles.”
Professor Bawendi said on Wednesday he was “honoured” to receive the award.
“I was very surprised, shocked, it was unexpected and I'm very honoured,” he said.
Professor Bawendi was born in Paris and grew up in France, Tunisia, and the US. He did his postdoctoral research under Professor Brus before joining MIT in 1990 and becoming a professor in 1996.
Professor Ekimov was born in the Soviet Union and worked for the Vavilov State Optical Institute before moving to the US.
In 1999, he was named chief scientist at Nanocrystals Technology Inc.
Hours before the announcement Sweden's Royal Academy of Sciences inadvertently published the names of the winners, although the award-giving institute said the decision was still hours away.
Johan Aqvist, chair of the academy's Nobel Committee for Chemistry, clarified that the committee had not yet decided on the winner.
However, those named earlier were the actual winners.
When asked if he already knew he had won, Professor Bawendi said he had been asleep and was unaware of the leak.
Carolyn Bertozzi of Stanford University, California, Morten Meldal of the University of Copenhagen, and K Barry Sharpless of Scripps Research, California, were cited “for the development of click chemistry and bioorthogonal chemistry”.
In 2021, the prize was awarded to Benjamin List and David MacMillan for finding an environmentally cleaner way to build molecules, which the Nobel panel said is “already benefiting humankind greatly”.
The prize, which is over 100 years old, is awarded by the Royal Swedish Academy of Sciences and is worth 11 million Swedish crowns ($990,019).
Which honey takes your fancy?
Al Ghaf Honey
The Al Ghaf tree is a local desert tree which bears the harsh summers with drought and high temperatures. From the rich flowers, bees that pollinate this tree can produce delicious red colour honey in June and July each year
Sidr Honey
The Sidr tree is an evergreen tree with long and strong forked branches. The blossom from this tree is called Yabyab, which provides rich food for bees to produce honey in October and November. This honey is the most expensive, but tastiest
Samar Honey
The Samar tree trunk, leaves and blossom contains Barm which is the secret of healing. You can enjoy the best types of honey from this tree every year in May and June. It is an historical witness to the life of the Emirati nation which represents the harsh desert and mountain environments

Why are asylum seekers being housed in hotels?
The number of asylum applications in the UK has reached a new record high, driven by those illegally entering the country in small boats crossing the English Channel.
A total of 111,084 people applied for asylum in the UK in the year to June 2025, the highest number for any 12-month period since current records began in 2001.
Asylum seekers and their families can be housed in temporary accommodation while their claim is assessed.
The Home Office provides the accommodation, meaning asylum seekers cannot choose where they live.
When there is not enough housing, the Home Office can move people to hotels or large sites like former military bases.

Basquiat in Abu Dhabi
One of Basquiat’s paintings, the vibrant Cabra (1981–82), now hangs in Louvre Abu Dhabi temporarily, on loan from the Guggenheim Abu Dhabi.
The latter museum is not open physically, but has assembled a collection and puts together a series of events called Talking Art, such as this discussion, moderated by writer Chaedria LaBouvier.
It's something of a Basquiat season in Abu Dhabi at the moment. Last week, The Radiant Child, a documentary on Basquiat was shown at Manarat Al Saadiyat, and tonight (April 18) the Guggenheim Abu Dhabi is throwing the re-creation of a party tonight, of the legendary Canal Zone party thrown in 1979, which epitomised the collaborative scene of the time. It was at Canal Zone that Basquiat met prominent members of the art world and moved from unknown graffiti artist into someone in the spotlight.
“We’ve invited local resident arists, we’ll have spray cans at the ready,” says curator Maisa Al Qassemi of the Guggenheim Abu Dhabi.
Guggenheim Abu Dhabi's Canal Zone Remix is at Manarat Al Saadiyat, Thursday April 18, from 8pm. Free entry to all. Basquiat's Cabra is on view at Louvre Abu Dhabi until October

Types of bank fraud
1) Phishing
Fraudsters send an unsolicited email that appears to be from a financial institution or online retailer. The hoax email requests that you provide sensitive information, often by clicking on to a link leading to a fake website.
2) Smishing
The SMS equivalent of phishing. Fraudsters falsify the telephone number through “text spoofing,” so that it appears to be a genuine text from the bank.
3) Vishing
The telephone equivalent of phishing and smishing. Fraudsters may pose as bank staff, police or government officials. They may persuade the consumer to transfer money or divulge personal information.
4) SIM swap
Fraudsters duplicate the SIM of your mobile number without your knowledge or authorisation, allowing them to conduct financial transactions with your bank.
5) Identity theft
Someone illegally obtains your confidential information, through various ways, such as theft of your wallet, bank and utility bill statements, computer intrusion and social networks.
6) Prize scams
Fraudsters claiming to be authorised representatives from well-known organisations (such as Etisalat, du, Dubai Shopping Festival, Expo2020, Lulu Hypermarket etc) contact victims to tell them they have won a cash prize and request them to share confidential banking details to transfer the prize money.
Red flags
- Promises of high, fixed or 'guaranteed' returns.
- Unregulated structured products or complex investments often used to bypass traditional safeguards.
- Lack of clear information, vague language, no access to audited financials.
- Overseas companies targeting investors in other jurisdictions - this can make legal recovery difficult.
- Hard-selling tactics - creating urgency, offering 'exclusive' deals.

What are NFTs?
Are non-fungible tokens a currency, asset, or a licensing instrument? Arnab Das, global market strategist EMEA at Invesco, says they are mix of all of three.
You can buy, hold and use NFTs just like US dollars and Bitcoins. “They can appreciate in value and even produce cash flows.”
However, while money is fungible, NFTs are not. “One Bitcoin, dollar, euro or dirham is largely indistinguishable from the next. Nothing ties a dollar bill to a particular owner, for example. Nor does it tie you to to any goods, services or assets you bought with that currency. In contrast, NFTs confer specific ownership,” Mr Das says.
This makes NFTs closer to a piece of intellectual property such as a work of art or licence, as you can claim royalties or profit by exchanging it at a higher value later, Mr Das says. “They could provide a sustainable income stream.”
This income will depend on future demand and use, which makes NFTs difficult to value. “However, there is a credible use case for many forms of intellectual property, notably art, songs, videos,” Mr Das says.

Tips to stay safe during hot weather
- Stay hydrated: Drink plenty of fluids, especially water. Avoid alcohol and caffeine, which can increase dehydration.
- Seek cool environments: Use air conditioning, fans, or visit community spaces with climate control.
- Limit outdoor activities: Avoid strenuous activity during peak heat. If outside, seek shade and wear a wide-brimmed hat.
- Dress appropriately: Wear lightweight, loose and light-coloured clothing to facilitate heat loss.
- Check on vulnerable people: Regularly check in on elderly neighbours, young children and those with health conditions.
- Home adaptations: Use blinds or curtains to block sunlight, avoid using ovens or stoves, and ventilate living spaces during cooler hours.
- Recognise heat illness: Learn the signs of heat exhaustion and heat stroke (dizziness, confusion, rapid pulse, nausea), and seek medical attention if symptoms occur.
