It has been organised for almost 40 years as a result of a strong cooperation between the Institute of Physics of the Czech Academy of Sciences in Prague [1] and the Institute of Molecular Physics of the Polish Academy of Sciences in Poznań. The seminar is organised every two years, alternating between Poland and the Czech Republic. The last seminar took place in Kouty about halfway between Prague and Brno in the centre of the Czech Republic. The single-session conference was organised at Hotel Luna located in a quiet place at a pond, surrounded by green forests. The 23rd Seminar started on the 21st and finished on the 25th of May 2018. The previous three seminars were organised in Hucisko in 2016 (Poland) [2], Sezimovo Ústí in 2014 (Czech Republic) [3] and Ustroń in 2012 (Poland) [4]. The conference history is connected with a number of remarkable names in the field of dielectrics and ferroelectrics [5–7] The seminar was mainly devoted to polar effects in solid state crystals but traditionally there was also an interesting session devoted to polar effects in soft matter. It was very motivating for people involved in liquid crystal science to listen and discuss about properties of solid state materials. The multidisciplinary nature of the topics was definitely an advantage of this seminar so that the meeting facilities were always busy. The Czech–Polish Seminar hosted around 110 participants from 14 countries. The biggest delegations obviously arrived from the Czech Republic (45 participants) and Poland (37). But there were also participants from Germany (6), the USA (6), Austria (3), the Russian Federation (3), Switzerland (2) and Hungary (2). One researcher per country arrived from Croatia, France, Ireland, Japan, Israel and Luxembourg. One can say that the Czech–Polish Seminar was truly an international event (Photo 1). The conference programme was broad and diverse. The schedule included 54 oral presentations of different lengths, from short 10-minute reports to 40-minute plenary lectures. In addition, 59 posters were presented and discussed during two poster sessions. The seminar was opened with an interesting guest lecture by P. Paruch entitled, ‘Nanoscale Studies of Novel Functional Properties at Ferroelectric Domain Walls’. One could notice several interesting presentations about liquid crystals in the seminar’s schedule. A. Emelyanenko presented a theory of transitions between smectic, nematic and isotropic phases and discussed a molecular-statistical approach to the description of various smectic phases and transitions between them. K. Merkel discussed the molecular origin of various layer contractions at the SmA-SmC transition. V. Novotná presented supramolecular selfassembly of liquid crystalline molecules that create nanotubes. A. Bubnov presented the self-assembly behaviour of new photosensitive cinnamoyl-based monomers ","PeriodicalId":18110,"journal":{"name":"Liquid Crystals Today","volume":"27 1","pages":"80 - 83"},"PeriodicalIF":3.1,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1358314X.2018.1525058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47399286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this period, when the industrial evolution of the field has been the subject of cycles of progresses and setbacks, it has witnessed the appearance and disappearance of many PDLC film and glass producers. Currently, there are over 15 PDLC film manufacturers and many more glass suppliers worldwide, creating a business turnover of more than $360million. During the first two decades, the global growth of the field had not been according to much anticipation. Only the past decade has witnessed a surge of worldwide demand and rapid growth. The most important factors responsible for the slow industrial growth of PDLC technology during the early development period had been the price, patent and, most of all, the business strategy of PDLC film producers. The details of the evolution history and market status of PDLC technology have been reported elsewhere [1,2]. The business models of the current PDLC film producers are either based on: a) the sales of film products to the glass processors without any transformation or installation knowledge and involvement to the final PDLC glass product or b) those who are also producing PDLC glass in-house, approach the end-use market alone. Besides these traditional business models, we identified a newcomer in the field with a different business model, namely Gauzy Ltd., which is briefly dealt with in the report.","PeriodicalId":18110,"journal":{"name":"Liquid Crystals Today","volume":"27 1","pages":"84 - 87"},"PeriodicalIF":3.1,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1358314X.2018.1525065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45760070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the focus of the meeting was on liquid crystal research and research groups in Germany, in keeping with the international character of Luxembourg, invitations were sent out to lab groups in the neighbouring Benelux countries as well as to France, resulting in approximately 100 participants (see Figure 1) from 17 different countries attending, including some from as far away as the west coast of the United States and from the Republic of Korea. The 2.5-day meeting was kicked off with a separate half-day mini-conference, e@(LC), a focused session on recent advances in liquid crystal elastomer research in Europe. This session featured four invited talks (Rudolf Zentel from the University of Mainz; Natalie Katsonis from the University of Twente; Verena Görtz from the University of Lancaster; and Arri Priimägi from Tampere University of Technology) and three contributed oral presentations, all covering aspects of elastomers from the chemistry and its optimisation, to fabrication strategies and methods, and all the way to novel applications. Following the elastomer mini-conference was the main event. After some opening remarks by Jan Lagerwall on behalf of the organising committee, the main sessions began, featuring five invited speakers (Figure 2); 26 contributed oral presentations, of which over half were given by Ph.D. students and postdoctoral researchers; and 42 posters, including 5 posters related to topics from the e@(LC) session. Apart from the focus on liquid crystal elastomers, a wide range of topics was discussed from both experimental and theoretical standpoints (or a combination of the two). The oral presentations of the main conference were sorted into six sessions: ‘Living Liquid Crystals and Collective Behavior’, with talks about biological and active nematics and liquid crystals in microfluidic set-ups; ‘Liquid Crystal and Nanoparticle Composites’, featuring talks on nanoparticle-doped liquid crystals and their applications; ‘Liquid Crystal Optics’; ‘Novel Phenomena and Applications’, which looked into previously unexplored applications of liquid crystals; ‘Novel Liquid Crystal Phases and Structures’, which looked into lyotropic smectics and the rheological properties of reduced-dimension liquid crystals; and ‘Liquid Crystal Chemistry’, which focused on the synthesis and characterisation of new liquid crystals and optimisation of synthesis pathways to achieve the desired outcomes.
