In Memoriam: Krzysztof JasikIt is with deep sorrow that we received the news of the passing of Krzysztof Jasik, a long-standing technical staff member of the Crystal Growth Laboratory NL-3 at our Institute. We have lost a truly reliable and conscientious colleague—someone we could always count on, both in everyday work and whenever help was needed. Krzysztof was a warm, kind, and exceptionally helpful person. He brought not only expertise and experience to our team, but also genuine goodwill and attentiveness to others. He will be remembered with gratitude and respect as someone who contributed greatly to the daily life and work of our laboratory and Institute. We extend our heartfelt condolences to his Family and Loved Ones. SPIE Photonics West 2026Scientists from our Institute will contribute a keynote presentation, five invited talks and one oral presentation at SPIE Photonics West 2026, the world’s largest photonics technologies event.

10th anniversary of IMaSS, Nagoya UniversityThe Institute of Materials and Systems for Sustainability (IMaSS), Nagoya University (Japan) celebrated its 10th anniversary in December 2025. Due to the active cooperation between IMaSS and our institute, we were invited to participate in this celebration. It was an honor for IHPP PAS and a meaningful sign of the strong relationship and scientific cooperation between our institutions. On the occasion of the anniversary, Professor Michał Boćkowski, Director of the Institute of High Pressure Physics PAS, presented IMaSS with a commemorative trophy with GaN crystal inside. In response, Professor Tomomi Uchiyama, Director of IMaSS, sent an official letter of appreciation to our Institute, emphasizing the significance of this thoughtful gesture and expressing his hope for continued collaboration and further development of academic ties between the institutions. We would like to thank IMaSS, Nagoya University for the warm welcome and kind words, and we wish continued success in its research activities.

IHPP PAS researchers to speak at the ISHA 2026 SeminarTwo researchers from the Institute of High Pressure Physics of the Polish Academy of Sciences (IHPP PAS, Unipress) will deliver presentations at an international online seminar organized by the International Solvothermal and Hydrothermal Association (ISHA) within the ISHA Seminar 2026 Series. The seminar will take place on January 26, 2026, from 12:00 to 14:00 (CET) and will focus on advanced topics related to the ammonothermal growth of gallium nitride (GaN) crystals, covering fundamental aspects of the process as well as the current state of the art and future development perspectives. During the seminar:
The session Chairperson will be Dr. Saskia Schimmel from Friedrich-Alexander-Universität Erlangen–Nürnberg (FAU), Germany. The seminar will be held online via Zoom platform. Participation is free of charge upon prior registration.
Ammonothermal GaN crystals and substrates. Fot. T. Sochacki IHPP PAS. Editor’s Choice ArticleWe are pleased to share that the article “Spontaneous and Piezo Polarization Versus Polar Surfaces: Fundamentals and Ab Initio Calculations” by P. Strak, P. Kempisty, K. Sakowski, J. Piechota, I. Grzegory, E. Monroy, A. Kaminska, and S. Krukowski, has been selected as an Editor’s Choice Article in the Materials journal by MDPI. The selection was made after a thorough evaluation by the journal’s Academic Editors, recognizing the paper for its academic originality, relevance to cutting-edge topics, rigorous argumentation, and clarity of structure, and the expectation that it will attract broad interest and academic attention. This paper presents fundamental insights into the interplay between spontaneous and piezoelectric polarization at polar surfaces, supported by ab initio (first-principles) computational analysis. The study advances understanding of how electric polarization phenomena influence the properties and stability of polar materials – a topic of high relevance for electronic, optoelectronic, and energy materials research. We congratulate the authors on this achievement and encourage to learn more about this work. Jaszowiec 202654th International School & Conference on the Physics of Semiconductors "Jaszowiec 2026" will be held on June 13-19, 2026, in Szczyrk, Poland. For over half a century, the Jaszowiec Conference has been connecting the national scientific community with leading international researchers, fostering collaborations, inspiring joint projects, and nurturing lasting friendships worldwide. The 54th edition will begin with a two-day tutorial School (June 13-14, 2026) chaired by Dr. hab. inż. Michał Baranowski from Wroclaw University of Science and Technology. The School is dedicated to graduate students and young scientists. It will be followed by the Conference (June 15-19, 2026) chaired by Prof. dr hab. Piotr Perlin from the Institute of High Pressure Physics PAS. The program will cover cutting-edge topics such as quantum and low-dimensional systems, light-matter interaction, magnetism and spin phenomena, devices and applications, and growth and characterization - presented through plenary lectures, topical sessions, and evening discussions for early-career researchers. The 54th edition will also include industrial lectures, an exhibition, and job fair for students.
