[(18)F]fallypride was synthesized in a batch microfluidic chip with a radiochemical yield of 65 ± 6% (n = 7) and an average specific activity of 730 GBq μmol(-1) (20 Ci μmol(-1)) (n = 4). Specific activity was ~2-fold higher than [(18)F]fallypride synthesized in a macroscale radiosynthesizer, despite starting with significantly less radioactivity, and thus safer conditions, in the microchip.
Peristaltic pumps are mechanical displacement pumps that induce flow in a fluid-filled, flexiblewalled conduit through peristalsis – transport due to traveling contraction waves. While macroscale peristaltic pumps appear in a variety of configurations, micropumps based on this principle almost exclusively use the sequenced contraction and expansion of a small number of discrete actuators – typi...
Results of 2D molecular dynamics (MD) method are presented for the mixing phenomenon in the microscale, where the length and time are measured in terms of microns and nanoseconds, respectively. Particle ensembles consisting of 0.7–3 × 106 particles in 1.3–5×105 timesteps were simulated. We focus on the temporal evolution of mixing layer between two superimposed Lennard–Jones particle systems in...
