Spider attachment hairs have outstanding adhesive properties that allow these creatures to walk upside-down on rough and smooth surfaces while carrying a multiple of their body weight. Spider feet are covered with thousands of specially designed hairs that have spatula-shaped tips made of composite material consisting of proteins and chitin fibres. The aim of Silja’s research is to reveal the structure-function mechanism of these hairs.

This research could be used, for example, to improve the longevity and efficiency of artificial sticky tapes or in the development of wall-climbing robots.

Looking to nature for innovation

“When I started this research, synthetic products based on the adhesiveness of spider feet already existed, for example the so-called “gecko tape”. However, the longevity of these synthetic products is still largely inferior to what is produced in nature. In this research, we are trying to see what in the structure of the hairs makes these natural systems stable for longer,” says Silja.

Silja Flenner, 26, is in the first year of a PhD at the Helmholtz-Zentrum Geesthacht, Centre for Materials and Coastal Research, in Germany. She first came to the ESRF for beamtime in 2015 and has been back several times since, working with the ESRF team on ID13. “The research has evolved from looking at the tip of the attachment hair to focussing today on the hair shaft. We’ve seen that the structure of the shaft changes depending where on the spider’s foot it is located.”

“I was surprised to receive the best poster prize at the ESRF and I’d like to thank all the beamline staff at ID13 for their support during my experiments here. Thanks, too, to my professor, Martin Müller, and to the biologist, Clemens Schaber, for giving me the opportunity to work on this exciting topic,” says Silja.

It’s Silja’s first time at the ESRF User Meeting and she hopes to become a regular in the coming years. “I learned a lot during the tutorial on tomography on Monday (T6) and what I really appreciate is that the meeting is well-scaled to allow you to see all the posters on show and have time to discuss with ESRF staff and other users. Thanks to the organisers for such a great event,” concluded Silja.

"Welcome everyone to the 28th ESRF User Meeting," said Paola Coan, head of the User Organisation. "Despite its great age, the User Meeting has maintained a dynamic and diversified programme and participation is on the rise this year."

Paola Coan continued her introduction to the meeting by recalling the successful year 2017 for the ESRF in terms of user popularity: the record number of proposals received and the record number of users coming on site was the most obvious sign of an active user community. She saluted the original ESRF storage ring that has served for the last 20 years and acknowledged the excellent science that has been produced in that time. “2018 also marks the end of an era for the original storage ring, as well as the beginning of a new era with the realisation of EBS, the first of a new generation of storage rings, and also the construction of new state-of-the art beamlines and an ambitious instrumentation programme."  She evoked the tremendous task that lay ahead for the ESRF and confirmed the confidence of the User Organisation in the successful achievement of EBS.

Paola Coan launched the plenary session. The first keynote speaker, Virginie Chamard from the Institut Fresnel, CNRS, at the Aix-Marseille  University, took the floor to talk about new X-ray microscopy techniques developed over the last few years and which can be used to shed new light on biomineralisation techniques.

The Plenary Session continues throughout the day with two further keynote lectures by

  • Hugh Simons, Technical University of Denmark, Department of Physics, Lyngby, Denmark
    • ​"Real-time 3D imaging of multi-scale material dynamics", and 
  • Jérôme Rose, Université Aix-Marseille III, Aix-en-provence, France
    • ​"Nanotechnologies risk assessment: exposure and product life cyle driven methodology"

Before lunch, the Directors' report will include presentations on the final three beamlines upgraded during Phase I, followed by a session dedicated to EBS with updates on the status of the machine, experimental programme and enabling technology programme. Then come the poster clips and one of the highlights of the day: the Young Scientist Award 2018.

The poster session will start at 17:40 and the winner will be announced during this evening's dinner.

What else has been happening at UM2018?

Flashback to Monday, when day 1 of the User Meeting saw the participants spread across the site of the EPN Campus, with 11 different tutorials on offer.

Over in the Science Building, the Partnership for Soft Condensed Matter (PSCM), opened the doors of its laboratories to show the facilities available, providing users and future users with a hands-on first approach to equipment and techniques.

“At the PSCM, we have around 60 instruments, half of which are major and can be booked online. They are available to all users and onsite staff for the preparation and characterisation of samples to be measured on the ESRF beamlines or using the neutrons at the ILL,” says Diego Pontoni, one of the tutorial organisers. For groups with a special interest in the facilities and seeking a long-term collaboration, it is possible to set up partnerships that include office/lab space and support for the development of new sample environments or tools.

The day concluded with the traditional bistrot evening in the marquee. While exchanging on science and enjoying the fine selection of local meats, cheeses and wines, we asked users why they had come to UM2018. Here's some of the replies we received :

web-whiteboardDay1.jpg

"I've come to visit the symposium UDM3 to find out which beamline I could use in the future for my science. And also for Tutorial T10 (Laue Microdiffraction)."

"Meeting friends, visiting beamlines.""To contribute to discussion on the future of structural biology."

"Great people and science!"

"I came for the wine, I stayed for the company!"

 

"To discuss on upcoming beamtime and tutorial T6 (Volume image analysis of tomographic data)."

"Come to talk science and do networking!"

"It's an important opportunity for communication about beamline performance, user guestions/issues, and plans to further develop this great machine."

"Because it's so cool and I have an experiment coming soon!"

"To be able to talk to users."

"To find cooperation partners."

"Curiosity driven, and for Tutorial T8 (Nuclear resonance applications)."
