Controlling the crystal phase of cobalt nanoparticles leads to exceptional catalytic performance in hydrogenation processes, scientists report. Produced via an innovative hydrosilane-assisted synthesis method, these phase-controlled reusable nanoparticles enable the selective hydrogenation of various compounds under mild conditions without the use of harmful gases like ammonia. These efforts could lead to more sustainable and efficient catalytic processes across many industrial fields.

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.

Researchers have achieved a significant breakthrough that could lead to better -- and greener -- agricultural chemicals and everyday products. Using a process that combines natural enzymes and light, the team developed an eco-friendly way to precisely mix fluorine, an important additive, into chemicals called olefins -- hydrocarbons used in a vast array of products, from detergents to fuels to medicines. This groundbreaking method offers an efficient new strategy for creating high-value chemicals with potential applications in agrochemicals, pharmaceuticals, renewable fuels, and more.

Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response: they are responding in context-appropriate manner. This knowledge potentially could be applied to train more sophisticated algorithms for scent-detecting drones to find the source of chemical leaks.
