Using long-wavelength terahertz radiation to produce video with a high frame rate

A team of researchers at Durham University has found a way to use long-wavelength terahertz radiation to produce video with a high frame rate. In their paper published in the journal Physical Review Letters, the group describes their technique and its possible uses.

But what about flow? The effect of hydrodynamics on liquid-liquid transitions

For a long time, the liquid state of pure substances was believed to be a continuous state in which the component atoms or molecules are all equivalent. However, it has now been widely shown that there can be multiple phases within liquids, even those containing only one component. Understanding what causes the components of liquids to switch from one state to another is currently a subject of particular interest. Researchers from the University of Tokyo Institute of Industrial Science have expanded the understanding of liquid behavior by describing the role of hydrodynamics in these transitions. Their findings are published in the Proceedings of the National Academy of Sciences (PNAS).

Quantum technologies: New insights into superconducting processes

The development of a quantum computer that can solve problems, which classical computers can only solve with great effort or not at all—this is the goal currently being pursued by an ever-growing number of research teams worldwide. The reason: Quantum effects, which originate from the world of the smallest particles and structures, enable many new technological applications. So-called superconductors, which allow for processing information and signals according to the laws of quantum mechanics, are considered to be promising components for realizing quantum computers. A sticking point of superconducting nanostructures, however, is that they only function at very low temperatures and are therefore difficult to bring into practical applications.

Not everything is ferromagnetic in high magnetic fields

High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in a zero field. Usually, high fields exceeding a certain critical value force the moments to align in the same direction as the field, leading to ferromagnetic arrangement. However, a recent study showed that this is not always the case. The experiments took place at the high-field magnet at HZB's neutron source BER II, which generates a constant magnetic field of up to 26 Tesla. This is about 500,000 times stronger than the Earth's magnetic field. Further experiments with pulsed magnetic fields up to 45 Tesla were performed at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).

Astronomy & Space news

Molecular oxygen detected in the nearest quasar

Observations using the IRAM 30 meter telescope and the NOEMA Interferometer have unveiled the presence of molecular oxygen in Markarian 231—the nearest known quasar.

The cosmic confusion of the microwave background

Roughly 380,000 years after the Big Bang, about 13.7 billion years ago, matter (mostly hydrogen) cooled enough for neutral atoms to form, and light was able to traverse space freely. That light, the cosmic microwave background radiation (CMBR), comes to us from every direction in the sky, uniform except for faint ripples and bumps at brightness levels of only a few part in one hundred thousand, the seeds of future structures like galaxies.

Surfing space dust bunnies spawn interplanetary magnetic fields

CHEOPS space telescope takes its first pictures

The tension was high: In front of a large screen at the house near Madrid where members of the Consortium participating in the commissioning of the satellite live, as well as at the other institutes involved in CHEOPS, the team waited for the first images from the space telescope. "The first images that were about to appear on the screen were crucial for us to be able to determine if the telescope's optics had survived the rocket launch in good shape," explains Willy Benz, Professor of Astrophysics at the University of Bern and Principal Investigator of the CHEOPS mission. "When the first images of a field of stars appeared on the screen, it was immediately clear to everyone that we did indeed have a working telescope," says Benz happily. Now the remaining question is how well it is working.

Qarman CubeSat: Falling into a fireball

This Wednesday 12 February, ESA's latest mission will enter the vacuum of space, not aboard a rocket but by being released from the International Space Station. The first task of the shoebox-sized Qarman CubeSat is simply to fall. While typical space missions resist orbital decay, Qarman will drift down month by month until it reenters the atmosphere, at which point it will gather a wealth of data on the fiery physics of reentry.

Camera provides view into Sun's polar regions

The Solar Orbiter mission will use a U.S. Naval Research Laboratory-designed and -built heliospheric camera, known as SoloHI, to provide unique perspectives and unprecedented views of the Sun's North and South poles. The spacecraft, a NASA and European Space Agency collaboration, launched aboard an Atlas V rocket at Cape Canaveral, Florida, Feb. 9.

Oblique electrostatic inject-deposited titanium oxide film leads efficient perovskite solar cells

The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites—materials with a particular crystal structure—is now competing with conventional silicon materials to satisfy the demand in this area. Perovskite solar cells (PSCs) are continually being optimized to fulfill their commercial potential, and a team led by researchers from Kanazawa University has now reported a new and simple oblique electrostatic inkjet (OEI) approach to deposit a titanium oxide (TiO2) compact layer on FTO-pattern substrates without the need for a vacuum environment as an electron transport layer (ETL) for enhancing the efficiency of PSCs. The findings are published in Scientific Reports.
