AI helps find formula for paint to keep buildings cooler
AI-engineered paint could reduce the sweltering urban heat island effect in cities and cut air-conditioning bills, scientists have claimed, as machine learning accelerates the creation of new materials for everything from electric motors to carbon capture.Materials experts have used artificial intelligence to formulate new coatings that can keep buildings between 5C and 20C cooler than normal paint after exposure to midday sun.They could also be applied to cars, trains, electrical equipment and other objects that will require more cooling in a world that is heating up.Using machine learning, researchers at universities in the US, China, Singapore and Sweden designed new paint formulas tuned to best reflect the sun’s rays and emit heat, according to a peer-reviewed study published in the science journal Nature.It is the latest example of AI being used to leapfrog traditional trial-and-error approaches to scientific advances.
Last year the British company MatNex used AI to create a new kind of permanent magnet used in electric vehicle motors to avoid the use of rare earth metals, whose mining is carbon-intensive.Microsoft has released AI tools to help researchers rapidly design new inorganic materials – often crystalline structures used in solar panels and medical implants.And there are hopes for new materials to better capture carbon in the atmosphere and to make more efficient batteries.The paint research was carried out by academics at the University of Texas in Austin, Shanghai Jiao Tong University, the National University of Singapore and Umeå University in Sweden.It found that applying one of several new AI-enabled paints to the roof of a four-storey apartment block could save electricity equivalent to 15,800 kilowatt hours a year in a hot climate such as Rio de Janeiro’s or Bangkok’s.
If the paint were applied to 1,000 blocks, that could save enough electricity to power more than 10,000 air conditioning units for a year.Yuebing Zheng, a professor at the University of Texas and co-leader of the study, said: “Our machine learning framework represents a significant leap forward in the design of thermal meta-emitters.By automating the process and expanding the design space, we can create materials with superior performance that were previously unimaginable.”He said a month’s work designing a new material was being done in a few days using AI and that new materials that may never have been discovered through trial and error were being created.“Now, we follow the machine learning output, [its instructions for] the structure and what kind of materials we should use, and we can get it right without going through many, many design and fabrication testing cycles.
”Dr Alex Ganose, a chemistry lecturer at Imperial College London who also uses machine learning to design new materials, said: “Things are moving very fast in this space,In the last year or so there have been so many startups trying to use generative AI for materials,”He said the process of designing a new material could require the calculation of millions of potential combinations,AI allows material scientists to push through previous restrictions in computational power,It also means the traditional process of creating a material and then testing its properties can be reversed, with scientists able to tell the AI what properties they want upfront.
How can I use leftover pickle brine in day-to-day cooking? | Kitchen aide
I’m an avid consumer of pickles, especially gherkins. When I’ve finished a jar, how can I use the brine in my cooking?Geoff, SheffieldLast year, Dua Lipa poured Diet Coke into an ice-filled glass, topped it up with the brine from both a tub of pickles (plus a few rogue pickles) and a tub of jalapeños, swirled it around, then drank it. While someone under the viral TikTok video asked, “Dua, is everything OK?”, the pop star is right about one thing: it’s time we start thinking of pickle brine as an ingredient, rather than a byproduct.“The brine retains all of that delicious pickle flavour,” says Moon Lee, head chef of no-waste restaurant Silo in London, “and a mixture of sweet and savoury undertones”. Also, because it’s fermented, “it has an almost tangy, kombucha-like taste, too
How to turn veg scraps into a delicious dip – recipe | Waste not
My friend Hayley North is a retreat chef whose cooking is inspired by the Chinese “five elements” theory: fire, earth, metal, water and wood. Each element corresponds to a colour and an organ in the body (earth, for example, is yellow and linked to the spleen). Years ago, Hayley made me the most deliciously vibrant and earthy bright-red dip from kale, and today’s recipe is a homage to her nourishing, elemental approach, while also saving scraps from the bin.I love the adage “eat the rainbow”. Yes, it’s a bit corny, but it works, and sometimes the simplest advice is really the best
Frittata, ‘egg and chips’ and a bean feast: Sami Tamimi’s brunch recipes from Palestine
What better way to welcome the weekend than with the smell and sound of herb-loaded ijeh frying? This is a thick, delicious frittata-like mixture of courgettes, leeks, peas, herbs and eggs, and in Palestine it’s often made with finely chopped onions, too. I always keep a couple of tins of ful (fava beans) in my pantry for those times when I crave a quick and satisfying late breakfast or weekend lunch. When simple toast and butter won’t do the trick and I’m in need of something more substantial and savoury, that’s when fava beans come to the rescue.You can substitute the eggs with feta for an extra-creamy and salty touch. Alternatively, the dish works beautifully as a vegan dish without the eggs
Jam tarts and summer pudding cake: Nicola Lamb’s recipes for baking with mixed berries
First up, a crostata-inspired jam tart that’s perfect for afternoon tea or nibbling throughout the day. Fennel seeds in the buttery pastry give a subtle flavour surprise, although you could omit them, or try coriander seeds or ginger instead. A small batch of jam is surprisingly quick to make, but you can, of course, use shop-bought, or make use of one of those jars living rent-free in your cupboard. Then, a summer pudding-inspired cake that makes a delightful centrepiece – the juices from the berries absorb into the top third of the sponge, giving it a gorgeous, ombre tone that looks as beautiful as it tastes.Use a mixture of whatever berries are plentiful; frozen will work well, too
Georgina Hayden’s recipe for spiced crab egg fried rice
Crab deserves to be celebrated, but that doesn’t mean it has to be a super-fancy, laborious meal. Crab midweek? Yes, please, and fried rice is my fallback whenever I am in a dinner pickle. That’s not to belittle its deliciousness, complexity or elegance, though, because this spiced crab version can be as fancy as you like. That said, the speed and ease with which I can create a meal that I know everyone will love is the winning factor. Plus, I often have leftover cooked, chilled rice in the fridge, anyway, which is always the clincher (cooked rice has a better texture for frying once chilled)
Rukmini Iyer’s quick and easy recipe for courgette linguine with trout, lemon and dill | Quick and easy
This is such a lovely, summery dish: it takes under 30 minutes from start to finish, and I found it immensely reviving after a long day. The grated courgette melts into the pasta, and works perfectly with the lemon, trout and a hit of chilli. If you have one of those multi-nut and seed mixes (the M&S 35-plant one is excellent), by all means add a scoop to finish; otherwise, a scattering of toasted pine nuts will add a welcome crunch. An elegant dinner for two.Prep 10 min Cook 20 min Serves 22 trout fillets 2½ tbsp olive oilSea saltJuice and finely grated zest of ½ lemon, plus 2 lemon slices180g linguine 2 garlic cloves, peeled and finely grated1 tsp chilli flakes1 large courgette, trimmed and coarsely grated10g fresh dill, roughly chopped 4 tbsp pine nuts, or 4 tbsp omega nut and seed mixHeat the oven to 200C (180C fan)/390F/gas 6
