Programme

Unfurtunately the monastery Irsee has been closed by the Bavarian government due to the corona virus.

Therefore we have decided to offer the conference as a web conference only.

In those unpredictable times, protecting our participants’ health has the highest priority for us!

The scientific exchange must not come to a complete standstill and we believe that with this web solution we have found a way to keep the scientific community going.

In order to participate in the livestream of the conference as easy as possible and to give your presentation, we recommend the use of the web browsers Google Chrome or Microsoft Edge.

Here you can find detailed instructions for using the livestream.

As a participant of the Bioinspired 2020 you have received an e-mail containing the login data for the web conference.

The login data for the sessions are provided daily.

In order to allow all conference participants access to the posters, we ask you to upload your poster by login on the conference homepage and clicking on the button "My Submission" in the upper right corner of the conference homepage. Then select the submission to which you want to upload the poster and upload the poster at the bottom of the page.

Furthermore we would like to ask all poster authors to prepare 4 PowerPoint slides to present your poster to the audience.
Please also include your contact details on the digital poster to allow participants to reach you with questions.

Please note that your poster will be pictured publically.

As poster author you can upload your poster similar to the way you submitted your abstract.
Click on "My Submissions" in the upper right corner at the homepage.

Poster documents can be found by opening the respective abstract in the online programme.
If a poster document has already been uploaded for the abstract, it can then be opened and downloaded.

Please note that your poster will be pictured publically.

You can ask your questions via chat already during the presentations!
Please use for this the Q&A (F&A) button!

For further scientific exchange we implemented a discussion forum on the homepage of the DGM.
Please visit discussion.dgm.de and use your DGM or Bioinspired user credentials to login.

Lecture

Bio-Inspired Soft Interfaces with Controlled Ice Formation and Adhesion

Tuesday (17.03.2020)
14:10 - 14:30

Soft interfaces and materials with freeze-tolerant and ice resistant properties are irreplaceable in life and materials science including engineering applications. Examples include cryopreservation, ice-templating, and robustness in functional coatings. Current advanced anti-icing strategies based on hydrophilic and hydrophobic materials exist but have intrinsic disadvantages, which limit their applicability.[1-3]

Our group aims to develop amphiphilic materials combining advantages of different ice preventing strategies such as supressing of freezing point using colligative properties or kinetic inhibition as well as de-icing strategies using low surfaces energy components. Specifically, we aim at the understanding of molecular origins of ice nucleation and formation at chemically heterogeneous interfaces and their correlation to macroscopic ice adhesion.[2] Ice formation from supercooled water drops is initiated by nucleation when the size of an ice embryo reaches a critical value. The lack of controlling the inception of heterogeneous nucleation and the rate of solidification, which depend on the properties of the substrate, temperature, and impact parameters of the liquid drop, poses a very serious challenge to the design of effective ice-preventing materials. In this exploratory experimental study, we show how a significant nucleation delay during impact of supercooled water drops can be achieved by tuning the properties of the substrate and, specifically, by introducing chemical and topographical heterogeneities on the surfaces formed by a mixture of either polymer-coated hydrophilic and hydrophobic particles or Janus particles.[3]
