Congrats to Mees

Last week, July 2, Mees Vos successfully completed his BSc thesis project, entitled: Synthesis of dynamic polymers grafted with bisimine pincer crosslinkers. In his BSc thesis project Mees demonstrated that imine-based pincers can be appended to a polymer backbone in order to introduce reversible crosslinks in the polymer network.

Awarded grant in Top Sector Chemistry Student Competition

The team Beads vs Beats was awarded a grant in the Top Sector Chemistry Student Competition, for a proposal entitled: “Metafoams: a new and effective material for sound isolation”. The team consists of students Sophie van Lange (WUR) and Roel Borgers (TUE), and will be supervised by Maarten Smulders (WUR) and Albert Poortinga (TUE).

In their project a highly efficiently sound-isolating material will be produced, aimed at the blocking of low-frequency sound. This novel material, or ‘metafoam’, will consist of a foamed polymer that encloses heavy beads in its pores. These beads will resonate with incoming sound waves, leading to destructive interference.

Lecture Esther van Andel at the ACS meeting in New Orleans

This Thursday, March 22, Esther will give a lecture during the 255th ACS National Meeting in New Orleans. The title of her lecture is: Highly selective capturing of biomolecules by antifouling zwitterionic polymer-coated microbeads. If you want to find out more about romantic beads (and if you’re in the neighbourhood) you should definitely check her lecture out (details on the ACS website).

Master Class Bert Meijer during 100-year anniversary of WUR

As part of the activities to celebrate the 100-year anniversary of Wageningen University Maarten Smulders will host a master class with chemist Bert Meijer, who is Distinguished University Professor at Eindhoven University of Technology and (amongst other awards) recipient of the 2001 Spinoza Award. In this master class, the scope and limitations of how to create artificial life from a chemistry perspective will be discussed.

Attendance is open to students and employees of WUR. For more information (and to register), please go the (WUR intranet) web page: https://intranet.wur.nl/umbraco/nl/actueel/master-classes-100th-dies-natalis-register-now/

New group members

This month we welcome the following people to the lab:

  • Dr Ghazal Tavakoli (visiting postdoc), who will be working on the synthesis of multivalent pincer complexes that can assemble into dynamic polymer materials.
  • Albert-Jan van Zuilichem (BSc student), who will be working on a project involving dynamic polymers, together with Dr Joshua Dijksman (Laboratory of Physical Chemistry and Soft Matter).

PhD vacancy

Our lab has a vacancy for a PhD position in the area of self-healing polymer coatings. The position is part of a NWO-funded CHIPP project (coordinated by m2i), entitled “Nanostructured self-assembled functional materials” (NanoFun), and is part of large network of 4 universities and 6 companies that are involved in this project.

For more details on the vacancy and to apply, please go to our university’s website.

Congrats to Sophie

Last week, Friday December 22, Sophie van Lange successfully completed her BSc thesis project, entitled: Synthesis and Rheological Characterisation of Dynamic Polymers. During her thesis project Sophie was co-supervised by Joshua Dijksman, assistant professor at our neighbouring Laboratory of Physical Chemistry and Soft Matter. In her project Sophie demonstrated that imine-based polymer networks display self-healing behaviour.

Paper in ACS Appl. Mater. Interfaces online

Our paper “Highly Specific Binding on Antifouling Zwitterionic Polymer-Coated Microbeads as Measured by Flow Cytometry“, describing work by Esther van Andel and Ian de Bus, has been published (as ASAP) in ACS Applied Materials & Interfaces. The paper describes the preparation of magnetic micron-sized beads coated with zwitterionic sulfobetaine polymer brushes that display strong antifouling characteristics. These coated beads can then be equipped with recognition elements of choice, to enable the specific binding of target molecules.
