Obituary Viriato Semião

It is with great sadness that we announce the sudden passing of Viriato Semião on January 31, 2025. His death has left an irreplaceable void in our professional community, where his contributions, mentorship, and leadership have had a lasting impact.Viriato was a distinguished professor for mechanical engineering at Instituto Técnico Lisboa with a strong focus on experimental and computational fluid mechanics. Inspired by the excellent research in membrane separations at IST, Viriato developed a passion for membranes, and the fluid dynamic analysis and optimization of membrane modules in particular. Viriato has always been known for his exceptional intellect, dedication, and unwavering professionalism. His work was marked by a pursuit of excellence, continuously inspiring those around him. With quiet strength and thoughtful guidance, he played a pivotal role in numerous successful research projects. Whether leading teams through complex challenges or offering support to colleagues, he instilled confidence and respect.Despite his many accomplishments, Viriato led with humility, focusing on the success of his colleagues and the betterment of the work. His ability to nurture talent, share knowledge, and foster collaboration earned deep respect from all who worked with him. During the first project year of BioMembrOS, Viriato not only actively contributed his exceptional expertise in fluid dynamics and mass transfer to the progress of our research – he also challenged our concepts by raising the right questions at the right time. And with his scientific expertise and experience, he always had a solution or an idea at hand – mentoring, inspiring and guiding our younger researchers.His sudden passing has left us heartbroken. Viriato’s legacy of excellence, integrity, and kindness will continue to inspire us. He was a colleague, mentor, and friend whose influence will never be forgotten. Our thoughts are with his family.Rest in peace, Viriato. You will be deeply missed.

Young Scientists Symposium 2024

On November 6th, 2024, we participated in the Young Scientists Symposium in Klosterneuburg, an event dedicated to fostering collaboration among early-career researchers. Our team presented two posters, "Multi objective Optimization of Hollow Fiber Membrane Oxygenators Arrangement Using Modified Enhanced Jaya Algorithm" and "Oxygen and Carbon Dioxide Transport Modeling in Extracorporeal Membrane Oxygenators with Sinusoidal Fiber Morphology" including our work on the BioMembrOS Project, highlighting key advancements and engaging in discussions with fellow scientists.To further promote our research, we distributed leaflets, providing attendees with insights into our project and encouraging future collaborations. The symposium served as an excellent platform for networking, exchanging ideas, and strengthening interdisciplinary connections.We look forward to future opportunities to engage with the scientific community and continue driving innovation.

European Researchers Night 2024

On 27th September 2024 we had the opportunity to present the BioMembrOS project at the European Researchers’ Night 2024. We were represented by Professor Mónica Faria with the Support of Post Doc Rita Pires, Phd Student Flavia Rodrigues and Master Students Margarida Valente and Johanna Grimm. Thanks to their help, the booth ran smoothly during the whole evening.Our booth was set up at "Pavilhão do Conhecimento" (Pavilion of Knowledge) and we were present  from 6pm until midnight. With approximately 1800 event attendees, the night was a success.In our booth visitors were  able to see and interact with a lab-scale extracorporeal (false) blood  circulation setup, fabricate flat sheet membranes and become familiar  with the project.
