Abstract & Biography | Karl Mandel

Particle technology from lab to pilot scale and nanotechnology 2.0 with supraparticles
In the first part of the talk, the merits of tailored nanoparticles, synthesized bottom-up in dispersions will be presented and underlined with examples. This is followed by a discussion on the challenges to upscale and process small (nano) particle suspensions.

In the second part of the talk, the next step, i.e., what I call “Nanotechnology 2.0”, will be discussed: This is, to consider these nanoparticles as the atoms of tomorrow [1] and build “molecules”, i.e., more complex particulate units from these building blocks.

Firstly, it will be argued in the talk why such objects should be termed supraparticles [2] and due to which new functionalities, such objects can be considered unique and a step beyond classical nanoparticle science.

Secondly, most recent findings of our group regarding novel functionalities for such particles will be presented.

Biography Dr. Karl Mandel, Fraunhofer ISC and Würzburg University
Karl studied Earth Sciences and Materials Science in Munich, Salzburg, Ulm and Oxford from 2005-2010 and did his PhD in Chemistry in Würzburg from 2010-2013. Since 2014 he is Head of the Particle Technology Group at the Fraunhofer ISC in Würzburg. Since 2018 he heads a second group besides the Fraunhofer group at Würzburg University, where Karl is also doing his Habilitation currently and where he has an Emil-Fischer-Fellowship, which is a Junior Professor equivalent status.

Karl`s research interest on the university side is on making complex particles from nano building-blocks, so-called supraparticles and study their novel functionalites, while on the Fraunhofer side he tries to upscale the syntheses and bring these particles into materials to create systems and products from it.

Karl has published over 50 papers in peer reviewed journals, a recent review on the topic of supraparticles, two book chapters and has 14 patent applications. He has given over 45 talks at national and international level.
