Abstract Manipulating surface strain via lattice mismatch can enhance electrocatalytic activity in epitaxial transition metal films, but long-term performance remains challenging. Although thick films can improve stability against dissolution, they may suffer from irreversible strain relaxation, reducing catalytic activity.

Abstract The rising demand for hydrogen calls for improvements in the efficiency of liquid alkaline water electrolysers (LAWEs), which can be fulfilled by advanced electrodes or separators. Nevertheless, they also intensify hydrogen crossover and safety concerns, thus mandating efficient mitigation strategies. Here we studied the correlation between cathodes and hydrogen crossover behaviours and mitigated safety risks by designing a gas recombination catalyst (GRC).

How ‘nuclear verdicts’ are driving up trucking costs — and the price of almost everything

|

Moving freight across the U.S. always carries risk. But in recent years, a fast-growing threat to the economics of trucking has erupted — not on the highway, but in the courtroom. “Nuclear verdicts,” legal and insurance shorthand for jury awards exceeding $10 million, have become more frequent and ever larger. What was once remarkable is now everyday news. That relentless climb is fundamentally reshaping the economics of trucking and, by extension, the cost of goods for ordinary Americans.
