Efficient fuel-molecule sieving using graphene      (via sciencedaily.com) 

A research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.

Chameleon-inspired coating could cool and warm buildings through the seasons      (via sciencedaily.com) 

As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers -- or warm in the winters -- without additional energy.

How wind turbines react to turbulence      (via sciencedaily.com) 

The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.

Verbal nonsense reveals limitations of AI chatbots      (via sciencedaily.com) 

The era of artificial-intelligence chatbots that seem to understand and use language the way we humans do has begun. Under the hood, these chatbots use large language models, a particular kind of neural network. But a new study shows that large language models remain vulnerable to mistaking nonsense for natural language. To a team of researchers, it's a flaw that might point toward ways to improve chatbot performance and help reveal how humans process language.

Images of simulated cities help artificial intelligence to understand real streetscapes      (via sciencedaily.com) 

To address the lack of suitable training data for deep-learning semantic segmentation models in urban landscaping, researchers developed a method that generates a training dataset without the need for real images or a model of an existing city. The method, which is based on procedural modelling and image-to-image techniques, enables segmentation models to achieve comparable performance under some conditions at a fraction of the cost of real dataset generation.
