Swiss Chemical Society Highlights Research of Junior Prize Laureates

The latest issue of CHIMIA, the membership magazine of the Swiss Chemical Society (SCS), is dedicated exclusively to the research of promising young scientists. Selected Ph.D. students from Switzerland present their work in 17 freely accessible scientific articles.

All of them were selected at the Swiss Chemical Society (SCS) Fall Meeting, which took place in 2018 at Ecole polytechnique fédérale de Lausanne (EPFL). It is one of the largest recurring meetings for the chemical sciences in Switzerland. In 2018 almost 900 participants from academic institutions and the chemical/pharmaceutical industry attended, and more than 400 poster contributions and 100 oral communications were presented, spanning all fields of chemistry from fundamental studies to applications in devices, drug development, and nanomaterials. For young researchers, the SCS Fall Meeting offers an excellent opportunity to share their recent scientific achievements with the larger community and to broaden their professional network.
CHIMIA 2019 4 Junor Prizes SCS
Each year, young researchers are honored for the scientific quality and impact of their contributions by the Best Oral Presentation Awards sponsored by Metrohm (see Fig. 1) and the Best Poster Presentation Awards sponsored by DSM (see Fig. 2). The awards include a certificate, a cash prize, and the invitation to contribute to issue 4 of CHIMIA.

First introduced in 2002, the award programs have become a key element of the Fall Meeting. The Award Ceremony is the last item on the agenda of an intense day, and certainly one of the meeting highlights.



One Example: Enriching the Toolbox for Colloid Synthesis

To pick one article as an example: Chengjun Kang, Zurich University of Applied Sciences, Switzerland, describes an alternative method to synthesize anisotropic particles with complex geometries and tunable surface morphologies to enrich the toolbox for colloid synthesis. Together with his colleagues, he has used atom transfer radical polymerization (ATRP) to grow nano- and micro-sized colloidal architectures directly from snowman-shaped Janus nanoparticle seeds (JNPS) by controlled radical polymerization. By doing so, they expand the scope of ATRP applications: Previously, ATRP has mainly been used for the synthesis of well-defined polymer chains both in solution and on the surface of materials.

In their work, the researchers incorporated an ATRP initiator into the solid bulk of a JNP. JNPs have at least two distinct chemical and/or physical properties on different sides of the same particle. Compared to conventional homogeneous nanoparticles, they have a much wider application potential in many fields.

During polymerization, monomers continuously add to the initiator containing the JNPS lobe. Growth conditions are controlled mainly through the interaction strength between the monomer and the JNPS. This leads to a variety of colloidal architectures, including dish-, basket, cocoon-, flower-, helmet- mushroom-, dumpling-, and pumpkin-like geometries. Furthermore, each of these grown architectures has different surface morphologies, including smooth, island, and grouped-island nanostructures.
