The newest publication from the BuBble-gun team has been selected Featured article in the Physics of Fluids journal! This work isthe result of the visit of prof. Andrew Dickerson from the University of Tennessee last year in January. In this collaboration, we investigated the microjet generated from channels with alternating stripes of hydrophilic (strong affinity to water) and hydrophobic surface (repelling water). We found that these wettability patterns have a large influence on the direction and the focusing of the jets. This allows for further tuning of the jet characteristics and better control of the microfluidic jet formation. Furthermore, the work was selected by the editors as a featured article!
