Published Bottled water can contain hundreds of thousands of previously uncounted tiny plastic bits
(via sciencedaily.com) Original source In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits, these particles are being consumed by humans and other creatures, with unknown potential health and ecosystem effects. One big focus of research: bottled water, which has been shown to contain tens of thousands of identifiable fragments in each container. Now, using newly refined technology, researchers have entered a whole new plastic world: the poorly known realm of nanoplastics, the spawn of microplastics that have broken down even further. For the first time, they counted and identified these minute particles in bottled water. They found that on average, a liter contained some 240,000 detectable plastic fragments -- 10 to 100 times greater than previous estimates, which were based mainly on larger sizes.
Published Revolutionizing stable and efficient catalysts with Turing structures for hydrogen production
(via sciencedaily.com) Original source Hydrogen energy has emerged as a promising alternative to fossil fuels, offering a clean and sustainable energy source. However, the development of low-cost and efficient catalysts for hydrogen evolution reaction remains a crucial challenge. Scientists have recently developed a novel strategy to engineer stable and efficient ultrathin nanosheet catalysts by forming Turing structures with multiple nanotwin crystals. This innovative discovery paves the way for enhanced catalyst performance for green hydrogen production.
