• Paper mill waste could unlock cheaper clean energy
  Scientists developed a high-performance hydrogen-production catalyst using lignin, a common waste product from paper and biorefinery processes. The nickel–iron oxide nanoparticles embedded in carbon fibers deliver fast kinetics, long-term durability, and low overpotential. Microscopy and modeling show that a tailored nanoscale interface drives the catalyst’s strong activity. The discovery points toward more sustainable and industrially scalable clean-energy materials.
• Researchers catch atoms standing still inside molten metal
  Scientists have uncovered that some atoms in liquids don't move at all—even at extreme temperatures—and these anchored atoms dramatically alter the way materials freeze. Using advanced electron microscopy, researchers watched molten metal droplets solidify and found that stationary atoms can trap liquids in tiny “atomic corrals,” keeping them fluid far below their normal freezing point and giving rise to a strange hybrid state of matter.
