Optical billiards on a microscale
24-08-2021…wo coupled microcavities. The entire complex structure was made of cadmium, zinc, and magnesium tellurides in the MBE laboratory, headed by Dr. Wojciech Pacuski. It took over 12 hours to produce the structure, and the thickness of each layer was made with an accuracy of a few nanometres (billionths of a metre). Then, the crystal was illuminated by a laser beam. The crystal absorbed the light and became excited for a short time (some tens of picose…

Join observation capabilities of these two telescopes would allow us to measure the masses of many free-floating planets. It would lead to a better understanding of the properties of these unusual objects,” explains Dr. Poleski. Details of the publication: “Kepler K2 Ca…

Artificial photosynthesis
25-05-2021…proach to building a highly conductive interface based on metallo-organic terpyridine wires forming a uniform and well-structured self-assembled monolayer (SAM) on the transparent conductive electrode composed of indium tin oxide (ITO). “We show for the first time that the TPY-ligand-SAM can be successfully used as a universal platform for the specific anchoring of the model electroactive protein (cytochrome c). The ITO-TPY nanosystem reported in…

Together against COVID-19
21-12-2020…iola Priesemann from the Max Planck Institute for Dynamics and Self-Organization, a leading author of a letter, calling for a pan-European vision to fight the viral spread. Researchers urge governments throughout Europe to agree on clearly formulated common goals, coordinate their efforts, develop regionally adapted strategies to reach the goals, and thereby work resolutely towards low case numbers. Panel: A joint European strategy for the COVID…

Fighting obesity
17-11-2020…Lipotoxicity is the process whereby fat molecules are deposited in non-adipose tissues. Like Dr. Jekyll and Mr. Hyde The researchers working at the UW Faculty of Chemistry: Dr. Maria Górna, Dr. Marta Kulik and Prof. Paulina Dominiak, specifically studied the PI3K signalling pathway. This is a major metabolic regulator, since it regulates fat storage and plays a major role in the cellular reaction to the hormone insulin. In obesity, diminished in…

Dr. Grzegorz Niedźwiedzki and colleagues analyzed via CT scanning the dentary anatomy and tooth structure of a recently described mammaliform species, Kalaallitkigun jenkinsi, discovered on the eastern coast of Greenland and dated Late Triassic. The species exhibits the…
