“…Mechanical micropumps are preferred over non-mechanical micropumps due to the increased flow rate against a moderate back pressure [10][11][12]. Similarly, valveless micropumps are preferred over check-valve and flap-valve micropumps [13,14] due to their ability to deliver particle-laden fluids, self-priming ability, simultaneous bi-directional pumping and mixing, reduced fatigue failure and the ability to deliver increased flow rates at maximum back pressures. The first valveless micropump was reported by Stemme et al [15]; most of the valveless micropumps developed to date have been fabricated in silicon, though recently polymer based valve-less micropumps have been developed, providing ease of fabrication and lower fabrication cost [13,16].…”

We report a planar solenoid actuated valveless micropump with multiple inlet–outlet configurations. The self-priming characteristics of the multiple inlet–multiple outlet micropump are studied. The filling dynamics of the micropump chamber during start-up and the effects of fluid viscosity, voltage and frequency on the dynamics are investigated. Numerical simulations for multiple inlet–multiple outlet micropumps are carried out using fluid structure algorithm. With DI water and at 5.0 Vp-p, 20 Hz frequency, the two inlet–two outlet micropump provides a maximum flow rate of 336 μl min−1 and maximum back pressure of 441 Pa. Performance characteristics of the two inlet–two outlet micropump are studied for aqueous fluids of different viscosity. Transport of biological cell lines and diluted blood samples are demonstrated; the flow rate-frequency characteristics are studied. Viability of cells during pumping with multiple inlet multiple outlet configuration is also studied in this work, which shows 100% of cells are viable. Application of the proposed micropump for simultaneous pumping, mixing and distribution of fluids is demonstrated. The proposed integrated, standalone and portable micropump is suitable for drug delivery, lab-on-chip and micro-total-analysis applications.

“…This has yielded research on several miniature piezoelectric pumps. 2,3) Most of these use valves to control direction of fluid flow but valves have issues with wear and tear and can cause clogging. This led to the development of valve-less micro pumps.…”

Auger recombination (AR) in quantum well (ow) semiconductors is re-investigated taking into account a realistic band structure instead of the usual parabolic approximation. Since direct AR is negligible in ows phonon-assisted AR is treated. The theoretical results are in good agreement with experimental investigations. In contrast, the description of ows by a reduced heavy-hole mass is insufficient. The influence of AR on the temperature dependence of semiconductor lasers is discussed.
