Open for Nominations: 2021 Soft Matter Lectureship

Do you know an early-career researcher who deserves recognition for their contribution to the soft matter field?

Now is your chance to put them forward for the accolade they deserve!

Soft Matter is pleased to announce that nominations are now being accepted for its 2021 Lectureship award. This annual award was established in 2009 to honour an early-stage career scientist who has made a significant contribution to the soft matter field.

The recipient of the award will be asked to present a lecture at an international conference in 2021, where they will also be presented with the award. The Soft Matter Editorial Office will provide £1000 financial support to the recipient for travel and accommodation costs.

The recipient will also be asked to contribute a research article to the journal and will have their work showcased free of charge on the front cover of the issue in which their article is published. The article would be subject to the normal peer review standards of the journal.

Eligibility

To be eligible for the lectureship, candidates should meet the following criteria:

  • Be an independent researcher, having completed PhD and postdoctoral studies
  • Be actively pursuing research within the soft matter field, and have made a significant contribution to the field
  • Be at an early stage of their independent career (this should be within 12 years of attaining their doctorate or equivalent degree, but appropriate consideration will be given to those who have taken a career break or followed an alternative study path)

Although the Soft Matter Lectureship doesn’t explicitly reward support of or contributions to the journal, candidates with a history of publishing or reviewing for the journal would be more likely to be considered favourably.

Selection

  • All eligible nominated candidates will be assessed by a shortlisting panel, made up of members of the Soft Matter Advisory Board and a previous lectureship winner.
  • The shortlisting panel will consider the nomination form and letter of recommendation, as well as the three recent research articles highlighted in the nomination form for consideration.
  • Shortlisted candidates will be further assessed by the Soft Matter Editorial Board, and a winner will be selected based on an anonymous poll.
  • Selection is not based simply on quantitative measures. Consideration will be given to all information provided in the letter of recommendation and nomination form, including research achievements and originality, contributions to the soft matter community, innovation, collaborations and teamwork, publication history, and engagement with Soft Matter.

Nominations

Nominations must be made via email to softmatter-rsc@rsc.org, and include the following:

  • A brief letter of recommendation (1 page maximum length)
  • A complete nomination form (includes list of the candidate’s relevant publications or recent work, 3 research articles to be considered during the shortlisting process, candidate’s scientific CV, and full contact details)

Please note:

  • Nominations from students and self-nomination is not permitted.
  • The nominee must be aware that he/she has been nominated for this lectureship.
  • As part of the Royal Society of Chemistry, we have a responsibility to promote inclusivity and accessibility in order to improve diversity. Where possible, we encourage each nominator to consider nominating candidates of all genders, races, and backgrounds. Please see the RSC’s approach to Inclusion and Diversity.
  • Candidates outside of the stated eligibility criteria may still be considered.

 

Nominations deadline: 30th November 2020

Hot article: Step-wise linking of vesicles by combining reversible and irreversible linkers – towards total control on vesicle aggregate sizes

Lipid bilayers are membranes consisting of two layers of lipid molecules. They have attracted an enormous interest from the research community, as they form the external envelope of cells. In three dimensions, these lipid bilayers can form vesicles, and such systems are currently used as models for many studies of cell signalling. In addition, they can be loaded with chemicals and used as drug delivery carriers. The performance of a drug delivery system formed by vesicles relies on their stability or, in other words, how much they tend to aggregate and in what manner. A system of vesicles where all of them aggregate into a very large cluster before they are even injected in the body will be of no use as it will not reach its target. On the other hand, if the vesicles all remain apart from each other indefinitely the dose applied in the target area might not be large enough to be effective.

 

Schematic representation of the individual vesicles with added C18-pNIPAm and added streptavidin before the temperature cycle.

In this publication, the authors design a vesicle system that enables full control over the aggregation of vesicles.  A combination of reversible and irreversible linkers is employed to form the vesicle aggregates, and such combination allows control of their size by setting the appropriate temperature program. The authors envisage that their method will be a useful tool for investigating membrane fusion phenomena or inter-membrane interactions, which are of high relevance in biological processes.

Comments from the authors:

  • We found that optimal conditions ​for self-limiting aggregation (defined in the text) are found when the lateral linker diffusion time is much shorter compared to the vesicle collision time. Experimentation at low vesicle concentration is therefore crucial/key.
  • Continued aggregation takes place at high temperatures (>32 degrees​ C) at high fractions of biotinylated lipids in combination with a high concentration of streptavidin. This aggregation can be stopped by lowering the temperature (C18-pNIPAm swells and prevents further aggregation). Rather than self-limiting aggregation, we have then obtained an aggregation start and stop mechanism using the C18-pNIPAm linker.
  • Optimizing the protocol for C18-pNIPAm synthesis, and varying the length of the pNIPAm polymer could further improve the control on final aggregation sizes.
  • Additionally, further control on the aggregation could be obtained varying the temperature steps. For temperature steps lower than 40 degrees​ C (but >32 degrees C), aggregation of vesicles is slower.
  • This work not only showcases the effect of combining biotin/streptavidin and C18-pNIPAm, but can also serves as a proof of principle for vesicle aggregation with other combinations of linkers, of which one of the linkers is reversible.

We are very pleased to welcome Dr Emanuela Zaccarelli as an Associate Editor for Soft Matter. Read more to learn all about Emanuela!

Emanuela Zaccarelli profile pictureEmanuela Zaccarelli has served on the Soft Matter Editorial Board for three years prior to becoming an Associate Editor for the journal, and is currently a Senior Researcher at the Institute of Complex Systems of the Italian National Research Council (CNR), based at the Physics Department of the Sapienza University of Rome. After graduating in Physics at the same University in 1999, she obtained a PhD in Physical Chemistry from the University College of Dublin, Ireland in 2002.

Emanuela’s main research interests are on phase behaviour and dynamic arrest of complex fluids, including colloids with depletion interactions, star polymers, microgels, clays and patchy particles. She mainly uses theory and computer simulations, often in connection with experimental work. She was the first recipient of the Soft Matter Lectureship in 2009 for her studies on gels and glasses in colloidal suspensions. In 2015 she was awarded an ERC Consolidator Grant to model the effective interactions of microgel particles. She is among the initiators of the “Italian Soft Days” series of meetings, which are aimed to gather together soft matter scientists working in Italy to favour collaboration and discussions among them.
