We cooperate for innovative food processingThursday, 13 February 2025 11:02 |
Cold pressing is the food preservation method with the aid of high pressure. It allows to extend its shelf life without the need to use preservatives. The food preserves its nutritional value and taste that is the greatest advantage of cold pressing method over heat treatment. It is crucial especially in the case of juices, vegetables, fruits, meat and other products. On February 5, 2025, a letter of intent was signed in Piotrków Trybunalski initiating cooperation between the Institute of High Pressure Physics of the Polish Academy of Sciences, the Łukasiewicz Research Network - Łódź Institute of Technology and the Piotrków Academy in the field of developing innovative processing technologies that will increase the shelf-life of food products based on high-pressure methods. Under the signed agreement, the Institute of High Pressure Physics PAS will build a modern cold pressure equipment, which will be used, among others, by students at the technical and agricultural faculty at the Piotrków Academy. Łukasiewicz – Łódź Institute of Technology brings to the project experience in research on technologies for the food industry, having modern laboratory facilities and expert scientific staff. The cooperation agreement was signed by: dr hab. Jacek Bonarek, prof. AP - Rector of the Piotrków Academy, prof. Michał Boćkowski - Director of the Institute of High Pressure Physics PAS, Hubert Cichocki - President of the Łukasiewicz Center and dr hab. Marcin Górski - President of the Łukasiewicz Research Network - Łódź Institute of Technology.

Unipress Thursday SeminarMonday, 10 February 2025 21:30 |
Understanding GaN solubility in ammonothermal method is fundamental for the growth of high structural quality and large size crystals. When NaNH₂ is used as a mineralizer, retrograde solubility mode is obtained, i.e. solubility decreases with increasing temperature. The next Unipress Thursday Seminar will be devoted to the recent studies of ammonobasic NaNH₂–GaN–NH₃ system as a function of temperature, pressure, dissolution time, mineralizer concentration, and the surface area of GaN feedstock, opening the way to the improvement of the growth conditions. The next Unipress Thursday Seminar will be given by dr inż. Tomasz Sochacki from Crystal Growth Laboratory, Institute of High Pressure Physics in the talk „On the solubility of GaN in the ammonothermal process – results and their thermodynamic analysis”. Join us online via Zoom platform on Thursday, Februaty 27, 2025 at 3:00 pm. To get the link to Zoom meeting, please contact us at dyrekcja@unipress.waw.pl Abstract of the talk is here.
WOCSDICE - EXMATEC 2025Monday, 27 January 2025 13:02 |
WOCSDICE - EXMATEC combines the 48th Workshop on Compound Semiconductor Devices and Integrated Circuits (WOCSDICE) with the 19th Workshop on Evaluation and Control of Compound Semiconductor Materials and Technologies (EXMATEC). It will take place at Cádiz, Spain, from 16 to 20 June 2025. Prof. Mike Leszczyński serves as a member of the Steering Committee for this scientific meeting. WOCSDICE is much more than a conference, it is a tradition that brings together the brightest minds from around the world to explore the future of compound semiconductors. With EXMATEC joining this event, it has become a meeting point where seasoned experts and young talents share discoveries, collaborate on groundbreaking ideas, and ignite the spark of innovation. Together, we celebrate not only science but also the passion, creativity, and connections that drive us forward.

Featured Article on defect levels in β-Ga2O3 crystalsTuesday, 18 February 2025 12:14 |
The Editors of Applied Physics Letters featured recently published article resulting from the collaboration of the Institute of High Pressure Physics PAS (Warsaw) and Leibniz-Institut fur Kristallzuchtung (Berlin). P. Kruszewski, A. Fiedler, Z. Galazka; The electric field influence on EC-0.18 eV electron trap level in (100)-oriented β-Ga2O3 crystals grown by the Czochralski method. Appl. Phys. Lett. 126 (6): 062110, 2025. https://doi.org/10.1063/5.0251567 In this study, we have shown that the electron trap level typically observed at Ec-0.18 eV in Czochralski-grown β-Ga2O3 crystals is actually a superposition of two distinct electron levels with closely matched activation energies, specifically Ec-0.196 eV and Ec-0.209 eV. Moreover, both trap states were found to be donors. This significant finding was achieved using the high-resolution Laplace DLTS technique, combined with carefully optimized experimental conditions.

Progress of high-Tc superconductors by high pressure growth techniqueSunday, 09 February 2025 14:09 |
The high-pressure growth approach is now recognized as a useful technique for enhancing the quality of materials and also their superconducting properties. The potential candidate Sm-based oxypnictide (Sm1111) exhibits the highest critical temperature of 58 K among iron-based superconductors. In the recent study, Dr. Singh's research team from our Institute conducted the first comprehensive investigation of the high-pressure development of Sm1111. Interestingly, the high-pressure technique led to only a small variation in the observed superconducting properties of Sm1111, which is the distinct behavior from other families of iron-based superconductors. More deatil about this study can be found in the published paper by Mohammad Azam, Manasa Manasa, Tatiana Zajarniuk, Ryszard Diduszko, Taras Palasyuk, Tomasz Cetner, Andrzej Morawski, Cezariusz Jastrzębski, Andrzej Szewczyk, Michał Wierzbicki, Shiv J. Singh entitled “High-pressure growth effects on the superconducting properties of Sm-based oxypnictide superconductors” Ceramics International (Elsevier) journal (2025); https://doi.org/10.1016/j.ceramint.2025.01.208

In the second research paper, Dr. Singh’s research team summarizes their findings based on the various families of iron-based superconductors under the effect of high-pressure growth techniques in the form of a short review.
