If a drop of creamer falls from a spoon into a swirling cup of coffee, the whirlpool drags the drop into rotation. But what would happen if the coffee had no friction — no way to pull the drop into a synchronized spin?
The high cost of platinum catalysts used in hydrogen fuel cells limits the commercialization of fuel cell electric vehicles. Scientists are studying alternative catalysts to increase cost-effectiveness and maintain efficiency of hydrogen fuel cells.
New research conducted at the Advanced Photon Source (APS) shows that 3D printing of metal components without the pores that weaken their structural integrity is not only possible, but would need no additional devices to realize.
Alzheimer’s disease is the sixth leading cause of death in the United States, affecting one in 10 people over the age of 65. Scientists are engineering nanodevices to disrupt processes in the brain that lead to the disease.
