Carbon-coated nickel enables fuel cell free of precious metals
A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, Cornell University researchers have found. The new discovery could accelerate the widespread use of hydrogen fuel cells, which hold great promise as efficient, clean energy sources for vehicles […]
Researchers recreate deep-Earth conditions to see how iron copes with extreme stress: New observations of the atomic structure of iron reveal it undergoes
Far below you lies a sphere of solid iron and nickel about as wide as the broadest part of Texas: the Earth’s inner core. The metal at the inner core is under pressure about 360 million times higher than we experience in our everyday lives and temperatures approximately as hot as the Sun’s surface. Earth’s […]
