Volodymyr Zelensky has warned Ukrainians to prepare for an increase in Russian attacks on the country’s infrastructure. The war-time president said his country could suffer attacks similar to the ones carried out by Vladimir Putin’s troops last year. About 10 months into Russia’s invasion, a string of attacks were carried out on power stations and other plants linked to the energy network, prompting rolling blackouts in widely separated regions. “We are almost halfway through November and we must be prepared for the possibility that the enemy may increase the number of drone or missile strikes against our infrastructure. Russia is preparing for winter,” the Ukrainian president said in his nightly address on Sunday. “And in Ukraine, all our attention should be focused on defence, on response to terrorists, on everything Ukraine can do to make it easier for our people to get through this winter and to increase the capabilities of our troops.” The warning comes shortly after Russian forces attacked Kyiv in the first-ever missile attack on the capital in nearly seven weeks. Strong explosions were heard, said Kyiv’s mayor Vitali Klitschko, adding that air defence systems were able to intercept the missiles, according to preliminary information. No casualties were reported. Russian strikes during last year’s winter offensive had left millions with no water and electricity in sub-zero temperatures. Moscow has already struck Ukrainian infrastructure 60 times in recent weeks, said Ukrainian officials. Energy minister German Galushchenko on Saturday, however, said Ukraine will have enough energy resources to get through winter. “The question is how much future attacks can affect supplies,” he said. Mr Zelensky also praised “heroic” efforts of troops defending Avdiivka, under pressure from attempted Russian advances since mid-October. The fighting has reduced much of the coking plant hub to a ghost town. While the attacks on Avdiivka slowed down in the past day, they are likely to intensify in the coming days, a military spokesperson said. “The enemy suffered significant losses the day before yesterday and has to regroup,” Oleksandr Shtupun, spokesperson for the southern group of forces, told national television. The number of infantry attacks were half of levels seen earlier in the week, he said. Moscow’s forces were “more active in the Bakhmut sector and trying to recover lost positions”, said General Oleksandr Syrskyi, the head of Ukraine’s ground forces. Russian accounts of the fighting on Sunday said its forces had repelled five Ukrainian attacks near Bakhmut.

Scientists have built a breakthrough device that can clean dirty water and turn it into clean hydrogen fuel. The “simple” device could be used in areas without resources or places where people live off the grid. And it is just one example of the many solutions that will be required to respond to pollution and give people access to both clean fuel and water, the researchers behind it say. The system is inspired by photosynthesis, the process where plants turn light into food. But previous versions of those “artificial leaves” have required clean water sources – whereas the new device can be used with polluted water and even produce clean drinking water at the same time. As such, scientists believe that it could help solve two problems at once: making green fuel and cleaning water so that it is ready to drink. “Bringing together solar fuels production and water purification in a single device is tricky,” said Chanon Pornrungroj from the University of Cambridge, the paper’s co-lead author. “Solar-driven water splitting, where water molecules are broken down into hydrogen and oxygen, need to start with totally pure water because any contaminants can poison the catalyst or cause unwanted chemical side-reactions.” The system uses a carbon mesh to absorb light and heat, creating water favour that is then turned into hydrogen for fuel by a photocatalyst. That carbon mesh also repels water, so that the system can float and its important parts can be kept from being damaged by water. The device is also able to harness more of the Sun’s energy than previous examples, which have used only a small portion of the spectrum of light. The new system has a white layer on top to absorb UV rays, with the rest being used lower down to vaporise the water. “This way, we’re making better use of the light – we get the vapour for hydrogen production, and the rest is water vapour,” said Dr Pornrungroj. “This way, we’re truly mimicking a real leaf, since we’ve now been able to incorporate the process of transpiration.” The researchers behind the breakthrough noted that the system was simple to make, and was especially able to deal with very polluted water. As such, it could be a key way of working towards a sustainable future, they said – even though it is just a proof of concept for now. “The climate crisis and issues around pollution and health are closely related, and developing an approach that could help address both would be a game-changer for so many people,” said Cambridge’s Erwin Reisner, who led the work. The device is described in a new paper, ‘Hybrid photothermal-photocatalyst sheets for solar-driven overall water splitting coupled to water purification’, published in Nature Water today.
