The Aachen-California Network of Academic Exchange, ACalNet, was an network which  integrates four university partners (RWTH Aachen University and University of California campuses at Berkeley, Santa Barbara and Los Angeles), two associated research institutions (Lawrence Berkeley National Laboratory and Forschungszentrum Jülich) and two industrial partners (CAT Catalytic Center and Schlumberger-Doll Research Center).

The academic members belong to different departments of the partner institutions, representing the interdisciplinary spirit of the network. Nuclear Magnetic Resonance and catalysis, was the main research area of ACalNet, are approached from a variety of different perspectives by the academic members, as can be observed in their individual research profiles.
