Prof. Dr. Ruy Alberto Pisani Altafim together with Prof. Dr. Axel Mellinger and his Ph.D. studend Neerajan Nepal, both from Central Michigan University, just have a new publication on the Journal of Applied Physics. The paper entitle: Space charge deposition in tubular channel ferroelectrets: A combined fluorescence imaging/LIMM study with finite element analysis, shows the evolution of electrical charging on ferroelectrets with open tubular channels. Through this work, it was demonstrated how the electrical charges are formed inside the channels during the barrie discharges.
