An efficient micromixer combining oscillatory flow and divergent circular chambers
Oscillatory/pulsatile flow is an important approach for mixing enhancement at micro scales. Here we report a micromixer that consists of a microfluidic oscillator and divergent chambers. The oscillator autonom...

Improvement of nucleation and electrical properties of Bi3.15Nd0.85Ti2.99Mn0.01O12 thin films with an upper Bi4Ti3O12 buffer layer
A highly (117)-preferred Bi3.15Nd0.85Ti2.99Mn0.01O12 (BNTM) thin film with an upper Bi4Ti3O12 (BTO) buffer layer was fabricated on Pt(111)/Ti/SiO2/Si(100) substrates by a sol–gel method. The effects of the added ...
