{"title":"Die bemerkenswerte Mobilität „unbeweglicher“ Seepocken","authors":"","doi":"10.1002/cite.202570303","DOIUrl":"https://doi.org/10.1002/cite.202570303","url":null,"abstract":"&lt;p&gt;Seepocken – diese kleinen, muschelartigen Krustentiere, die oft Schiffsrümpfe, Felsen und sogar Meeresschildkröten bedecken – galten lange Zeit als sesshafte Lebewesen. Einmal angeheftet, so die gängige Meinung, verbringen sie ihr gesamtes Leben an ein und demselben Fleck. Doch die Forschung von Professor Dr. Benny Kwok-Kan Chan vom Biodiversity Research Center (BRC) der Academia Sinica in Taiwan zeigt, dass diese Annahme nicht immer zutrifft.&lt;/p&gt;&lt;p&gt;Chan und sein Team machten eine erstaunliche Entdeckung: Manche Seepocken, insbesondere jene, die auf Schildkröten leben, können sich entgegen der landläufigen Annahme fortbewegen. Mithilfe spezieller Zementproteine, die sie produzieren, können sie ihre Haftung lösen, sich gleitend über die Oberfläche bewegen und sich anschließend wieder fest verankern. Diese Fähigkeit ermöglicht es ihnen, sich an verändernde Umgebungsbedingungen anzupassen und beispielsweise beschädigte Stellen auf dem Schildkrötenpanzer zu verlassen.&lt;/p&gt;&lt;p&gt;Doch ihre Forschung offenbarte noch weitere Überraschungen. So stellte das Team fest, dass Seepocken in verschiedenen Lebensstadien und für unterschiedliche Funktionen spezifische Zementproteine einsetzen. Larven und Adulte verfügen über eigene Sets dieser vielseitigen Klebeproteine. Interessanterweise ähneln sich die Zementproteine von Seepocken, die ähnliche Lebensräume bewohnen. Dennoch gibt es Unterschiede in der Anzahl bestimmter Proteinvariationen. Diese Vielfalt ist der Schlüssel zur bemerkenswerten Anpassungsfähigkeit der Seepocken an verschiedenste Umgebungen.&lt;/p&gt;&lt;p&gt;Für diese Arbeit zeichnete die Gesellschaft Deutscher Chemiker (GDCh) Chan nun mit dem Mario-Markus-Preis für ludische Wissenschaften aus. Der mit 10 000 Euro dotierte Preis wird von Professor Dr. Mario Markus, Dortmund, finanziert, der sich der ludischen Wissenschaft verschrieben und diesen Begriff geprägt hat. Er würdigt wissenschaftliche Arbeiten aus dem Bereich der Naturwissenschaften, die sich durch ihren spielerischen Charakter auszeichnen. Chans Entdeckungen beruhen auf seinem spielerischen Forschungsansatz. „Ludisch“ bezeichnet dabei eine Herangehensweise, die von Neugier, Experimentierfreude und Kreativität geprägt ist. Der Blick in die Wissenschaftsgeschichte zeigt, dass bahnbrechende Erkenntnisse oft auf solch spielerischen Wegen gewonnen wurden. In einer Zeit, in der Forschung zunehmend unter dem Aspekt der konkreten Anwendbarkeit steht, erinnert der Mario-Markus-Preis daran, dass Wissenschaft immer auch von Neugier und Spieltrieb lebt.&lt;/p&gt;&lt;p&gt;Doch auch Chans „spielerische“ Forschung eröffnet bereits Anwendungsperspektiven. Das neu gewonnene Verständnis der Zementproteine könnte beispielsweise zur Entwicklung neuartiger, starker Unterwasserklebstoffe beitragen. Von der Seepockenforschung zu innovativen Materialien – dieser Weg zeigt exemplarisch, wie zweckfreie Grundlagenforschung und anwendungsorientierte Entwicklung oft Hand in Hand gehen.&lt;/p&gt;&lt;p&gt;Benny Kwok-Kan Chan studierte zunächst Umweltwiss","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 3","pages":"140-141"},"PeriodicalIF":1.5,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202570303","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the filtration kinetics of a depth filter can be investigated using various model approaches (dendrite growth model or fiber growth model) to describe particle separation in the clogging phase, it is not yet possible to transition to surface filtration by continuing the same model calculation. A new modeling approach with a multilayer construction and an offset for the growth of the dust cake is presented, which enables the description of particle separation by using analytical models throughout the entire filtration process without a separate add-on model for the change between depth and surface filtration. The continuous evaluation of the locally resolved structural changes, i.e., in the individual sub-layers, as well as the associated changes in the separation efficiency of the single-collectors in the growing two-component filtering system provide insightful information about the filtration kinetics during the entire filtration process and about the process of dust cake formation.¹⁾</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 4","pages":"334-343"},"PeriodicalIF":1.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202400154","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
