Publication in Bioactive Materials IF=18.0 Friday, 11 October 2024 15:23 |
The cooperation of two institutes of the Polish Academy of Sciences (the Institute of Metallurgy and Materials Science in Krakow and the Laboratory of High Pressure Plasticity of our Institute of High Presure Physics) resulted in a publication in the prestigious journal Bioactive Materials.
The paper M. Gieleciak, A. Jarzębska, Ł. Maj, P. Petrzak, M. Kulczyk, Ł. Rogal, and M. Bieda "Influence of magnesium addition on microstructural and mechanical stability of hydrostatically extruded biodegradable zinc alloys" Bioactive Materials 44, 1 (2025) shows the effect of hydrostatic extrusion on the properties of biodegradable zinc-magnesium alloys. The process of shaping the properties of these materials using high pressures impacts their homogeneity and microstructure fragmentation (mechanical properties) as well as thermal stability in operating conditions (as an implant in a living organism).
Unipress Thursday SeminarThursday, 03 October 2024 11:40 |
Development of bioabsorbable metals is of great importance since they can be used to produce temporary implants, replacing permanent ones, and thus limiting some harmful side-effects related to their long-term presence in a patient body. One of the most promising materials for such an application is zinc (Zn) due to its optimal corrosion rate. However, the mechanical properties of pure zinc are far from being acceptable for a proposed application. Alloying with other elements and additional plastic deformation such as hydrostatic extrusion (HE) can significantly improve material strength thus enabling applications for orthopedic fixtures such as bone screw implants. Institute of High Pressure Physics PAS invites you to its Unipress Thursday Seminar that will be given by dr inż. Jacek Skiba from Laboratory of Plastic Deformation Under High Pressure, Institute of High Pressure Physics. The talk is titled „Advanced zinc alloys for biomedical applications - Effect of plastic deformation by hydrostatic extrusion method on microstructure, mechanical and functional propertiess” Join us online via Zoom platform on Thursday, October 31, 2024 at 3:00 pm.

3rd Polish-Slovenian International Seminar on Soft MatterWednesday, 25 September 2024 12:31 |
The 3rd Polish Slovenian International Seminar on Soft Matter will be held on-line on September 26-28, 2024. Directors: dr hab., prof. Aleksandra Drozd-Rzoska (IWC PAN, Warsaw, Poland) and prof. Sami Kralj (Univ. Maribor & Josef Stefan Inst., Ljubljana, Slovenia). These are 30 lectures in the following sessions (i) Biological & Living Soft Matter), (ii) Colloidal Soft Matter, (iii) Bio-Complexity, (iv) Applications of Soft Matter, (v) Phase Transitions and Critical Phenomena in Soft Matter, and (vi) Glass-Forming Systems. 17 lectures will be given by outstanding specialists from Slovenia, Poland, Italy, Mexico, Denmark, Japan, Belgium, France. The remaining 13 lectures are presentations of particularly interesting results by young researchers on their way to the status of ‘outstanding’ specialists. Next there is a poster session with interesting results from young researchers that will complement the picture, and the Worskshop ‘Show YourSelf in Science’, which is dedicated for young scientists. This workshop is organized and will be chaired by three PhD students finishing their thesis at the Faculty of Marketing, University of Economics in Katowice. The event is online.

Dualtronics - novel concept for monolithic device integrationWednesday, 25 September 2024 17:03 |
Scientists from MBE Laboratory NL14 at the Institute of High Pressure Physics PAS (IHPP PAS, Unipress), in collaboration with groups at Cornell University (CU), have published the results of their recent study in Nature in a paper "Using both faces of polar semiconductor wafers for functional devices" by L. van Deurzen, E. Kim, N. Pieczulewski, Z. Zhang, A. Feduniewicz-Zmuda, M. Chlipala, M. Siekacz, D. Muller, H.G. Xing, D. Jena, and H. Turski. Demonstrated device is the first monolithic integration of a light source (light-emitting diode, LED) and a transistor (high electron mobility transistor, HEMT) on opposite sides of the same bulk semiconductor substrate. Therefore the authors introduce a term "dualtronics" to describe this concept and differentiate it from previous solutions. By using a polar bulk GaN substrate - recognized as the highest-quality bulk GaN substrate available, also grown at Unipress - they were able to amplify the advantages of the devices by utilizing the built-in field inherent in the material. The monolithic integration of both devices on the same crystal enables the full utilization of the substrate's surface area and allows for denser packing of LED pixels. Bulk crystal growth, surface preparation, dual-side epitaxial growth (schematically shown in the figure below), and initial characterization were all performed at IHPP PAS. Meanwhile, the dual-side processing of the LED and HEMT, microscopy characterization, and monolithic modulation of light emission from the LED by the HEMT were carried out at CU. This work represents a promising starting point for the broader development of dual-side integrated optoelectronic and electronic devices, not only within the III-nitride material system.
