Not all surfactants work. We had to understand the mechanism of crust formation, which explained why only some of the surfactants work. |
Their initial pump was designed for a six-foot-tall, healthy male. So the pump was sized for the flow this 180-pound guy who plays tennis would have. Most of the patients that need this pump aren't that person. |
We understand the mechanism, and we have shown that the system is very similar to the drying of a polymer solution. Because of this understanding, the process could be controlled, adapted, and scaled-up to other situations, e.g. continuous coatings. |
