Going Non-Linear: Contrasting LCDM with the internal properties of galaxies

News: Institute of Physics - Thu, 08/06/2023 - 16:01
Abstract: The Lambda Cold Dark Matter (LCDM) paradigm has been spectacularly successful at reproducing observations of the cosmic microwave background and of the large-scale structure of the Universe. On these scales, the structures contrasted with the theory are in the linear or mildly non-linear regime, where observations are well established and theoretical predictions are robust. LCDM also makes specific predictions in the non-linear regime; in particular, for the evolution, abundance, structure, and substructure of dark matter halos, the sites of galaxy formation. On these non-linear scales a number of potential challenges to LCDM have been identified when confronting the observed internal structure of galaxies with LCDM expectations. I plan to review briefly the status of these challenges and to discuss whether they signal a potential breakdown of the LCDM paradigm or just reflect our incomplete understanding of the complex process of galaxy formation.    The seminar will be held in the SOLID21 lecture hall in the SOLID21 building of the Institute of Physics, Na Slovance 2, Prague 8 on the ground floor. Location: The seminar will be also available via ZOOM video conference system: Meeting ID: 674 9629 6646 Passcode: 575511

Refining Cardiovascular Risk Stratification in Patients using Graphene-based bioFETs

News: Institute of Physics - Tue, 16/05/2023 - 09:52
Cardiovascular diseases (CVDs) remain one of the leading causes of death worldwide. To improve therapeutic outcomes and reduce health care costs, a better understanding of disease-specific variation across cardiac patients is needed with emerging technologies providing innovative opportunities in the form of home diagnosis. Electrical biosensors are especially promising when interconnected with 2D materials such as graphene. Despite impressive achievements in the electrical performance of graphene-based field effect transistors (gFET), some key bottlenecks need to be tackled: reproducibility of gFET preparation, maintaining high mobility after surface modification and sensing in high ionic strength medium.

Biosensors as a public health tool – research by a team of scientists from the Institute of Physics of the Czech Academy of Sciences has been published by the prestigious Journal of Travel Medicine

News: Institute of Physics - Thu, 11/05/2023 - 15:30
Scientists from the Institute of Physics of the Czech Academy of Sciences have published the results of extensive research in the field of public health. Their aim was to map the occurrence of SARS-CoV-2 virus in Prague public transport during the COVID-19 pandemic. The team from the Laboratory of Functional Biointerfaces, led by Hana Lísalová, developed special biosensors for testing. Their use has provided new insights into the fight against infectious diseases.  The research, which has recently been published in Journal of Travel Medicine, was implemented in collaboration with the Biology Centre of the Czech Academy of Sciences, University of South Bohemia in České Budějovice, Taiwanese Academia Sinica, ELI ERIC and Prague Public Transit Company.

New crystallographic method will help pharmacists and faster computers

News: Institute of Physics - Tue, 25/04/2023 - 09:44
Swapping your left shoe for the right one while putting them on is unpleasant, but swapping molecules in the same way when making medicines can be fatal - instead of a drug poison is produced. A new method invented by a team of international scientists led by Lukas Palatinus from the Institute of Physics of the Czech Academy of Sciences will help prevent this. The unique procedure for determining the position of atoms in crystals was published last week in the Nature Chemistry.

Verhagen's recipe for 2D sandwiches: you layer single-atom layers of different materials

News: Institute of Physics - Tue, 18/04/2023 - 15:13
Description Dr. Timotheus Verhagen ve své budoucí laboratoři In an ambitious project, Tim Verhagen, a dutch scientist at the Institute of Physics of the Czech Academy of Sciences, aims to create a new type of material that will have simultaneously ferromagnetic and ferroelectric properties at room temperature. The project, which is funded by the European Research Council (ERC), involves the deposition of very thin, single-atomic layers of different materials on top of each other to create so called “2D sandwich".

Sensors developed with Czech support help protect water consumers in Europe

News: Institute of Physics - Tue, 04/04/2023 - 06:04
Water pollution is endangering more lives annually than all forms of violence and war. Accessible sources of clean water are limited. Less than 1 percent of the planet's freshwater is available to us. The international Aqua3S project proposes innovative solutions to water facilities, as well as the standardization of current existing sensor technologie.

Spontaneous lattice distortion in HoB4

News: Institute of Physics - Mon, 03/04/2023 - 12:27
The rare earth tetraboride HoB4 was studied in detail by using X-ray powder diffraction in the temperature range of 3.5 − 8 K to investigate the crystal structure of this compound below its Neel temperature TN1 = 7.1 K. The system undergoes a first order transition of magnetic nature at TN2 = 5.7 K, yet the crystal structure is already distorted in between these two magnetic transitions. In fact, crystalline unit cell changes from the tetragonal symmetry with P4/mbm space group to a monoclinic symmetry. The ground state of this tetraboride compound at 3 K found to be best described by the space group P21/b. Furthermore, large bifurcation in unit cell volume between the warming and cooling cycle was observed, if the data are treated with tetragonal crystal symmetry - providing an additional support that the crystal structure is distorted indeed.
