Researchers at the National Institute of Standards and Technology (www.nist.gov) have developed a new method to produce uniform, self-assembled nanocells for drug therapies, such as chemotherapy, in which dosage depends critically on the size of the nanocells. The new method uses micrometer-size channels etched into a device to produce self-assembled liposomes—a type of artificial nanocell—of specific sizes from 100 to 240 nm. A stream of lipids dissolved in alcohol is directed at an intersection of two channels while a water-based liquid containing medicines or other substances is sent toward the lipid stream from two opposing directions. Self-assembled nanocells are formed when the lipids surround the water rather than mixing with it.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
