Every year, the members of KiNSIS award the Diels Planck Medal to a leading international scientist in the field of nano and surface sciences. The awardee is chosen by the KiNSIS members and invited to give a public lecture, the Diels Planck Lecture.

The winner of the Diels Planck Medal 2023 is Valeria Nicolosi (Trinity College Dublin).

She will give the Diels Planck Lecture as part of the KiNSIS Symposium on 9 October 2023 at the Wisseschaftszentrum Kiel. Traditionally, the 2023 KiNSIS doctoral prizes are also awarded at the Diels-Planck Lecture in order to bring together top-class established scientists and young researchers. The award winners will briefly present their dissertations.

Please register online by 31 August 2023 **extended to 15 September 2023**

"Processing and applications of two-dimensional nanosheet inks"
Valeria Nicolosi, Trinity College Dublin, School of Chemistry, CRANN Institute, AMBER and I-Form Centres, Dublin 2. Ireland

Abstract: Liquid phase exfoliation has been proved to be a cheap, scalable method for the mass production of 2D sheets. This talk will first discuss the galaxy of existent layered materials, with emphasis on synthesis, liquid-phase exfoliation, and characterization, focussing on some key applications recently developed in our laboratories, ranging from energy storage to printed electronics. We will for example discuss how two-dimensional Ti3C2 (MXene) can be formulated in aqueous and organic viscous inks for extrusion printing and inkjet printing, respectively, and demonstrate direct MXene printing on various substrates. The additive- and binary solvent-free MXene inks do not show coffee ring effect, enabling high-resolution printing without substrate pre-treatment. The resulting all-MXene printed micro-supercapacitors showcase excellent charge storage performance, including areal capacitance up to 43 mF/cm2 and volumetric capacitance up to 562 F/cm3 in protic gel electrolyte, coupled with long lifetime and good flexibility. We also show examples of all-inkjet-printed MXene arrays for ohmic resistors. The versatile direct-ink-printing technique highlights the promise of MXene functional inks for scalable fabrication of easy-to-integrate components of printable electronics. We will also discuss how MXenes can be used as a conductive binder for silicon electrodes produced by a simple and scalable slurry-casting technique without the need of any other additives. The nanosheets form a continuous metallic network, enable fast charge transport and provide good mechanical reinforcement for the thick electrode (up to 450 µm). Consequently, record high areal capacity anodes (up to 23.3 mAh cm−2) can be demonstrated. EMI shielding applications will also be discussed.
