In this research there was looked at the connection between the Zeta potential and the pressure sensitivity of a chloroprene dispersion in order to gain insight in dispersion stability. This was done by varying the pH and ionic strength of the chloroprene dispersion. There was also looked at whether …

Er zijn verschillende manieren om software te deployen. Echter, niet alle manieren zijn even veilig en consistent. Ook kost het tijd als het proces niet geautomatiseerd is. Dit heeft vooral te maken met het aantal beschikbare tools om dat te doen en omdat het onduidelijk is wat een goede manier van standaardiseren …

ARS-CoV-2 can spread by close contact through large droplet spray and indirect contact via contaminated objects. There is mounting evidence that it can also be transmitted by inhalation of infected saliva aerosol particles. These particles are generated when breathing, talking, laughing, coughing or …

Introducing a hyperbolic vortex into a showerhead is a possibility to achieve higher spray velocities for a given discharge without reducing the nozzle diameter. Due to the introduction of air bubbles into the water by the vortex, the spray is pushed from a transition (dripping faucet) regime into a …

Cutaneous melanoma is a type of skin cancer that develops from benign melanocytes to one of the most aggressive types of skin tumors in human. In cutaneous melanoma progression, the metastasis phase is the most challenging phase to treat. To enable earlier treatment options, a better understanding of …

Electrohydrodynamic atomization (EHDA) is a technique which uses the influence of strong electric fields to manipulate the break-up of a liquid, pumped through a capillary nozzle, into droplets. In this work, an extended description of a specific high flow EHDA mode, known as the simple-jet mode, is …

In certain conditions, (part of) an oil spill can disappear from the water surface through a process called natural dispersion. One available oil spill response option is to enhance this process by addition of dispersants (chemical dispersion). An informed decision for such response requires insight …

With a market demand for low cost, easy to produce, flexible and portable applications in healthcare, energy, biomedical or electronics markets, large research programs are initiated to develop new technologies to provide this demand with new innovative ideas. One of these fast developing technologies …

In this study, we experimentally investigated the material flows of coloured dyes in coalescing small inkjet printed droplets of different volume ratios. With two differently coloured dyes, one in each droplet, we were able to distinguish the time-resolved contributions in dye transport across the coalescence …

Laboratory research was done on flat glass substrates to study the effect that brine salinity has on adhesion mechanisms between oil and clay particles. This is done by evaporating a small clay suspension droplet (6 ul) on a glass slide that leaves a thin layer of clay upon which oil can be attached. …
