Researchers at The University of Manchester discovered that intense electronic excitation can trigger rapid structural changes in metals, driven by electronic entropy. The study found that almost all elemental metals undergo solid-to-solid phase transitions driven solely by this effect.
Researchers developed a one-pot synthesis strategy for hierarchical ZSM-5 catalysts that can improve catalyst lifetime during microwave-assisted catalytic pyrolysis of plastic waste. The study found that crystallization temperature strongly controlled the catalyst's pore structure, acidity, morphology, and lifetime.
A new mathematical framework, STIV, can predict larger-scale effects like proteins unfolding and crystals forming without costly simulations or experiments. The framework solves a 40-year-old problem in phase-field modeling, allowing for the design of smarter medicines and materials.
Researchers at Pohang University of Science & Technology experimentally demonstrated the existence of nanometer-sized liquid clusters in supercritical fluids, overturning the prevailing notion of a single phase. These clusters persisted for up to an hour and have significant implications for industrial processes and natural environments.
Cornell researchers discover way to control metal solidification transformations by adjusting alloy composition, leading to improved strength and reliability of printed metal parts. The method involves disrupting column-like grain growth, significantly reducing grain size and improving yield strength.
Researchers at Tohoku University successfully prototyped the world's first full-scale automotive multi-material component, a suspension tower made of steel and aluminum with tailored geometry. The breakthrough in Laser Powder Bed Fusion (L-PBF) technique allows for strong bonding interfaces without brittle intermetallic compounds.
RMIT researchers have found that the liquid-solid boundary can fluctuate back and forth, with metallic atoms near the surface breaking free from their crystal lattice. The phenomenon occurs at unexpectedly low temperatures and is observed up to 100 atoms in depth.
Scientists discovered oscillatory bifurcation patterns on liquid metal surfaces, mirroring the cyclic power blocs in 'Romance of the Three Kingdoms.' The unusual patterns emerge due to surface instability, with potential applications in plasmonic sensing and high-efficiency electronics.
Researchers at the University of Seville have developed a procedure for producing boron carbide phase B6C, an ultra-resistant material with a hardness of 52 GPa and Young modulus of 600 GPa. The material is resistant to radioactivity and surpasses diamond in hardness.
