“Hydrogen fuel cells are enormously powerful, enabling you to run at an efficiency that simply does not exist for more traditional engines,” Abruña said.
Cornell chemists have discovered a class of nonprecious metal derivatives that can catalyze fuel cell reactions about as well as platinum at a fraction of the cost.
A new study published Sept. 7 in the journal of the International Union of Crystallography demonstrates that cryo-EM samples can be prepared with a safer and less expensive coolant – liquid nitrogen – and these samples can produce even sharper images than those prepared with ethane.
In a new interdisciplinary study combining mathematics and engineering, researchers simulated models to show that drivers obey digital signs that direct them toward less-congested routes--but sometimes the signs don't keep pace with highway realities.
