Every day, we’re surrounded by billions of tiny, unseen objects. Molecules of all kinds float like invisible motes of dust, impossible to detect with the naked eye but sometimes discernable through smell.
“Think about when you buy a home — you may have new furniture, such as sofas, mattresses, or memory foam pillows, and freshly painted rooms,” says Nithin Abraham, a thermal coatings engineer at NASA’s Goddard Space Flight Center. “These common household items often have a new smell associated with them, and it’s a result of volatile organic compounds being released into the air.”
As part of her job, Abraham has to think on the tiniest of scales. At NASA, she works on coatings technology research efforts. Specifically, she tries to address molecular contamination, finding ways to keep molecules from interfering with delicate instruments bound for space. Even the smallest deposition of chemical species on a sensitive telescope mirror can keep it from working properly. [Read more…]
