Influence of the distribution of the properties of permanent magnets on the field homogeneity of magnet assemblies for mobile NMR
Yannick Klein, Leon Abelmann, Han Gardeniers
We optimised the magnetic field homogeneity of two canonical designs for mobile microfluidic NMR applications: two parallel magnets with an air gap and a modified Halbach array. Al…
Influence of Bubbles on the Energy Conversion Efficiency of Electrochemical Reactors
Andrea Angulo, Peter van der Linde, Han Gardeniers +2
Bubbles are known to influence energy and mass transfer in gas evolving electrodes. However, we lack a detailed understanding on the intricate dependencies between bubble evolution…
Bacterial Footprints in Elastic Pillared Microstructures
Arturo Susarrey-Arce, Jose Federico Hernandez-Sanchez, Marco Marcello +9
Soft substrates decorated with micropillar arrays are known to be sensitive to deflection due to capillary action. In this work, we demonstrate micropillared epoxy surfaces are sen…
Taming Acoustic Cavitation
David Fernandez Rivas, Bram Verhaagen, Oscar R. Enriquez +4
In this fluid dynamics video we show acoustic cavitation occurring from pits etched on a silicon surface. By immersing the surface in a liquid, gas pockets are entrapped in the pit…
Efficient Sonochemistry through Microbubbles Generated with Micromachined Surfaces
David Fernandez Rivas, Andrea Prosperetti, Aaldert G. Zijlstra +2
Sonochemical reactors are used in water treatment, the synthesis of fine chemicals, pharmaceutics and others. The low efficiency of sonoreactors have prevented its massive usage at…
Sonoluminescence and sonochemiluminescence from a microreactor
David Fernandez Rivas, Muthupandian Ashokkumar, Thomas Leong +5
Micromachined pits on a substrate can be used to nucleate and stabilize microbubbles in a liquid exposed to an ultrasonic field. Under suitable conditions, the collapse of these bu…
