A review of rare earth element-containing materials finds that cerium, lanthanum, and other REEs can improve redox behavior, oxygen mobility, electrochemical activity, charge separation, hydrogen storage, and membrane performance across several hydrogen-production technologies. Most advances remain at laboratory scale, with wider deployment dependent on cost, resource availability, extraction impacts, long-term stability, recycling, and techno-economic feasibility.
The advanced manufacturing technologies have driven mechanical equipment toward higher speeds, greater loads, and longer service lifetimes. The intensive and high-frequency operation inevitably leads to friction and wear of mechanical components, compromising their reliability, functionality, and service life, as well as leading to safety issues and causing considerable waste of energy and resources.
Composite and lead-free piezoelectric materials offer new design options for ultrasonic transducers, with tailored properties for frequency, sensitivity, power, and flexibility.
For decades, we have treated used nuclear fuel as high-level waste to be buried and forgotten.
Researchers developed isosorbide-based plasticizers that made brittle poly(isosorbide carbonate) more flexible while preserving its ability to undergo ammonolysis after use. The resulting degradation products supported plant growth, including in an edible vegetable, highlighting a new way to design plastics with a useful end-of-life function.
With rockets propelling it down the sled track at Sandia National Laboratories, a semitrailer loaded with mock nuclear weapons slammed into a barrier.
With TopMap Sherpa, Polytec introduces a new software generation for its topography measurement systems.
Reducing weight, improving energy efficiency, changing composite- production processes and advancing towards more sustainable materials have become some of the transport sector’s main challenges.
The review compares phase inversion, film stretching, melt extrusion, sacrificial templating, and electrospinning as routes to PFAS-free waterproof breathable membranes. It finds that no single method maximizes waterproofness, breathability, durability, and scalability, highlighting the need for application-specific design and standardized testing.
The U.S. Department of Energy’s SLAC National Accelerator Laboratory will lead a Genesis Mission project to help secure the nation’s critical mineral supply by developing AI tools to improve recovery of valuable transition metals from spent lithium-ion batteries.
