June 2020 liquid crystal picture

Image of "Trapped transitions", by John Sandford O'Neill, has been selected as the June 2020 ILCS liquid crystal picture. Jury finds it visually very attractive with the distribution of different spreading lines and the positioning of shapes of different colours.


Final Call for Voting

Dear ILCS Members:
I hope this email finds you all well.
I am writing to make the final call for your vote for the next President and Vice President of the ILCS.

May 2020 liquid crystal picture

Image of "Arrival of the spring", by Greta Babakhanova, has been selected as the May 2020 ILCS liquid crystal picture. Jury finds it very well observed and the combination of detailed observation of defect textures and artistic sensibility is very nice.


ILCC 2020 Postponed

Dear ILCS Members and Colleagues:

I hope this email finds you well in the time of coronavirus pandemic.
As announced on the website of the ILCC 2020 the Organizing Committee and the ILCS have made a decision to postpone the 28th ILCC to 2022.
Given the significance of this biennial event, we have been making every effort to minimize the negative impact of postponement. The honors and awards ceremony and the presentations by the awardees will be conducted on-line during the original conference period. Details will be communicated to you as soon as possible.

To keep our community alive and well through this difficult time, your understanding and contributions are very much appreciated.

President, ILCS

In response to the global pandemic caused by the novel coronavirus, the Organizer of the 28th International Liquid Crystal Conference (ILCC) and the International Liquid Crystal Society (ILCS) has made a decision to postpone the 28th ILCC in Lisbon for a similar week in 2022, dates to be confirmed. Information will be placed on the conference website. Consequently, the 29th ILCC to be held in Brazil is rescheduled to 2024. Postponement of the ILCC is unprecedented in the long history of the conference since its inception in 1965. The 28th ILCC has attracted enthusiastic submission of over 650 papers from all over the world and from all generations of scientists working at the frontier of the liquid crystal research. The real global nature of the liquid crystal community has made this decision inevitable to assure the safety of its members.

In order to make up for the loss of personal gathering in Lisbon this year, we are planning to hold the awards session on-line, to make sure that the awardees get their prizes and have a chance to present their research. We are diligently working out the specifics of the web-based presentations on the basis of on-going assessment of demand from the community.

The 28th ILCC in 2022 will refresh the program to reflect the up-to-date advances of the field.

We will keep you informed of any further development about the ILCC. Please visit the conference website often to get the latest information.

Other relevant information:
Participants who had already paid the ILCC2020 registration will receive a refund, please contact Ms. Madalena Almeida from Abreu.
Participants who had already booked a Hotel through Abreu (our Backoffice company), please contact Ms. Madalena Almeida from Abreu.
Participants who had already booked and paid the Students Residence Halls, please contact SASNOVA.
Finally, we apologize for the disappointment and inconvenience you may have. Your understanding and continued support is very much appreciated.

Best wishes for your health and wellbeing in this difficult time.

April 2020 liquid crystal picture

Image of a Spiral Smectic Filaments of Bent-core Mesogen, by Venkatesh Gude, has been selected as the April 2020 ILCS liquid crystal picture. Jury likes the aesthetics of your yellow/green spirals on a black background, showing the filament  structures, both right handed as well as left handed. of the B7 phase. It will now be featured on the home page of the ILCS website until the end of the month.

March 2020 liquid crystal picture

The image of a “Coexistence of three types of smectic texture of 8CB”, by Satoshi Aya, has been selected as the  March 2020 ILCS liquid crystal picture. The picture of three coexisting textures  of 8CB  in the SmA phase is very aesthetic and as well as instructive.  It show beautifully the  diversity of different textures of the SmA phase. The composition is striking with different fields of colour  with high visual contrasts and as a picture it looks very dynamic.

February 2020 liquid crystal picture

Image of a focal conic defect texture in ferroelectric liquid crystals, by Ambika Bawa, has been selected as the  February 2020 ILCS liquid crystal picture. The combination of  the closed packed helices in a hexagonal lattice together with a chirality of the helices is very impressive; illustrating self assembly on various length scales in a very nice manner.
