In Centrifugal Field-Flow Fractionation (CF3) the separation force is
established by a centrifugal field, which is generated by spinning the
complete circular channel at a high rate. The bigger and denser
particles are forced more in the direction of the outer wall than the
smaller particles. As a consequence, bigger particles are eluted later
from the CF3 channel as they are located in slower streamlines in the
channel than the smaller particles which are located in faster stream
anoscale technology has greatly improved our daily lives with products such as computers, phones, and solar cells. To develop the next-generation nanotechnology, new classes of materials need to be explored. Two-dimensional “valley semiconductors,” such as monolayer molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), have remarkable properties and novel applications.
