New research demonstrates how glycerol carbonate, a biosourced industrial additive, can be produced in record time using CO2 and a by-product of the cooking oil recycling industry. The process relies on a hybrid approach combining fundamental physical organic chemistry and applied flow process technology. Two industrial wastes are thus converted into glycerol carbonate, a biosourced rising star with high added-value.

Researchers have developed artificial muscles that are lighter, safer and more robust than their predecessors. The newly developed actuators have a novel type of shell structure and use a high-permittivity ferroelectric material that can store relatively large amounts of electrical energy. They therefore work with relatively low electrical voltage, are waterproof, more robust and safer to touch.

Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.

Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers are trying to give robotic assistants the tools to help inspectors with the job.

Global warming continues to pose a threat to human society and the ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming. To combat climate change and move towards the goal of carbon neutrality, researchers have developed a durable, highly selective and energy-efficient carbon dioxide (CO2) electroreduction system that can convert CO2 into ethylene for industrial purposes to provide an effective solution for reducing CO2 emissions.

Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.

Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.

Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.
