Magnetic or nonmagnetic substitution generally plays a significant role on the properties of a superconductor. It can induce disorder into the crystal, produce the impurity scattering, and cause a Cooper pairbreaking effect. Recently, Dr. Singh's research team from NL-6 has published a research paper that explores the non-magnetic Cu impurity effect on the high T_c iron-based superconductor through various types of measurements and analysis, including DFT calculations. This study concludes that the substitution of Cu in the superconducting FeAs layer results in the enlargement of the lattice volume and is a source of strong disorder scattering that leads to the suppression of superconducting properties and the emergence of a metal-to-insulator transition.

12th International Workshop on Nitride Semiconductors (IWN 2024) will be held this year in O'ahu, Hawai'i, on November 3-8, 2024. It is organized by Profs.Zlatko Sitar and Ramón Collazo.

The IWN 2024 will bring together researchers from around the world to discuss the latest advances in the field of III-Nitride semiconductors. IWN 2024 will celebrate the achievements of Profs. Asif Khan and Russel Dupuis as honorary chairs.

Prof. Czesław Skierbiszewski from our Institute will have a plenary talk „Tunnel Junctions for Novel Nitride Optoelectronic Devices”.

Jak wynika z analizy opublikowanej niedawno w Gazecie Wyborczej, Instytut Wysokich Ciśnień zajmuje 10. miejsce na liście polskich publicznych organizacji badawczych, które uzyskały najwięcej patentów za pośrednictwem Europejskiego Urzędu Patentowego (EPO).

Unipress, z 23 patentami europejskimi przyznanymi w ciągu ostatnich 10 lat, ustępuje jedynie niektórym największym uczelniom i plasuje się na pierwszym miejscu wśród instytutów Polskiej Akademii Nauk, wyprzedzając Instytut Biofizyki i Biochemii PAN posiadający 16 patentów. Lider klasyfikacji, Uniwersytet Jagielloński w Krakowie, uzyskał 82 patenty europejskie. Jeśli uwzględnić także firmy i instytucje prywatne, zajmujemy solidne siedemnaste miejsce, działając przecież w nieporównywalnie mniejszej skali.
