What is SCAATTM? How can we increase the 4-inch GaN bulk crystal diameter if the Ni-based superalloys material properties cannot withstand higher pressures? Are 8-inch bulk GaN crystals a dream or reality?
These questions will be adressed by Dr. Yuji Kagamitani from Mitsubishi Chemical in a talk on “Acidic Ammonothermal Growth of Bulk GaN” during next Unipress Thursday seminar.

3-D projectors used without polarization goggles are the "Holy Grail" of optoelectronics. In the Institute's Laboratory of Semiconductor Characterization, we have developed two technologies which could pave the way to such projectors. Both are based on AlGaInN epitaxy on GaN substrates after lateral patterning. However, there are a lot of problems to be solved. The question is if they can be solved?
Join us on Wednesday, March 27, 2024 at 3:00 pm for the next online Unipress Thursday seminar. Prof. Mike Leszczyński from our Institute of High Pressure Physics PAS, the Laboratory of Semiconductor Characterization will give a talk entitled "Multicolour laser diode arrays for 3-D projectors - science fiction?".
Why nuclear energy is the optimal energy source and why it is so difficult to build nuclear power plant today? These and other fundamental questions will be addressed in the coming Unipress Thursday seminar by prof. Jacek Jagielski from the National Centre for Nuclear Research.
The seminar will be held on-lineon Thursday, February 22, 2024 at 3:00 pm. The title of the presentation is "Energy for the future, or why we need nuclear power". Join the seminar if you would like to hear about the current concepts of Generation III and IV reactors, problems, risks and costs related to the implementation of nuclear power.

Implants allow us to recover quickly and efficiently after serious orthopedic injuries. It is known that the implant surface plays a key role in the organism's biological response, influencing implant regrowth and stability. In order to make implatnts more biocompatible, their surface can be covered by hydroxyapatite.
The next UNIPRESS Thursday seminar will be devoted to a novel method of implant coating - SonoNanoCoating (SNC). Urszula Szałaj from our Institute, the Laboratory of Nanomaterials will present its advantages and discuss the preliminary results obtained in her recent study. The title of her presentation is "SonoNanoCoating as a versatile method for hydroxyapatite coatings application on the surfaces of implants".
