Chemists at the University of Münster develop method for simple production of vicinal diamines Among the most common structures relevant to the function of biologically active molecules, natural products and drugs are so-called vicinal diamines - in particular, unsymmetrically constructed diamines. Vicinal diamines contain two functional atomic groups responsible for the substance properties, each with a nitrogen atom bonded to two neighbouring carbon atoms.

Researchers at Freie Universität Berlin took part in a new study on chiral molecules recently published in "Science Advances" In a recent study, researchers at Freie Universität Berlin, the DESY research center in Hamburg, Kiel University, and Kansas State University have shown how light can turn a planar molecule into a chiral molecule with just one particular handedness, providing a solution to the long-standing problem of absolute asymmetric synthesis.

In the macro world, friction doesn't depend on the speed at which two surfaces move past one another, but researchers from Basel and Tel Aviv have now observed precisely this effect in special graphene structures on a platinum surface. December 2022 Due to their low-friction properties, materials consisting of single atomic layers are of great interest for applications where the aim is to reduce friction — such as hard disks or moving components for satellites or space telescopes.

Youri van Hees defended his PhD thesis at the department of Applied Physics on December 7th. Due to the ever-increasing growth of our data consumption, researchers are looking for faster, more efficient, and more energy-conscious data storage techniques.

Unconventional computing combines Brownian computing with reservoir computing / First prototype developed A large percentage of energy used today is consumed in the form of electrical power for processing and storing data and for running the relevant terminal equipment and devices. According to predictions, the level of energy used for these purposes will increase even further in the future.

Patient study demonstrates benefits of dark-field X-ray technology A research team at the Technical University of Munich (TUM) has, for the first time, produced dark-field X-ray images of patients infected with the corona virus. In contrast to conventional X-ray images, dark-field images visualize the microstructure of the lung tissue, thereby providing additional information.

Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

A new study involving researchers at the University of Illinois Chicago achieved a milestone in the synthesis of multifunctional photonic nanomaterials. In a paper published in the American Chemical Society's journal Nano Letters , they report the synthesis of semiconductor -giant- core-shell quantum dots with record-breaking emissive lifetimes.

X-ray diffraction measurements under laser-driven dynamic compression allow researchers to investigate the atomic structure of matter at hundreds of thousands of atmospheres of pressure and temperatures of thousands of degrees, with broad implications for condensed matter physics, planetary science and astronomy.

Researchers at the University of Innsbruck investigated the effect of nuclear magnetic resonance on cryptochrome, an important protein of the "internal clock". To their surprise, the results of the experiments could only be explained by quantum mechanical principles - and could enable completely new therapeutic approaches.

Modern solar cells work with thin layers of semiconductors that convert sunlight into electrical energy. The key to increasing their efficiency even further lies in the composition and structure of the material. Due to the way the material is manufactured, it can have defects that have a disruptive effect.

Things are looking brighter than ever at the Berkeley Lab Laser Accelerator (BELLA) Center run by the Department of Energy's Lawrence Berkeley National Laboratory. A recently completed upgrade will expand the center's capabilities into new areas, including studies of particle acceleration, extremely hot plasmas, cancer treatment techniques, and materials for quantum science.

Researchers in Mainz and Kyushu established a novel strategy for the generation of highly energetic UV light Many photochemical processes rely on UV light from inefficient or toxic light sources that the LED technology cannot replace for technical reasons. An international team of scientists led by Professor Christoph Kerzig of Johannes Gutenberg University Mainz (JGU) in Germany and Professor Nobuhiro Yanai of Kyushu University in Japan has now developed the first molecular system for the conversion of blue light into high-energy UV photons with wavelengths below 315 nanometers.

An international collaboration involving the Autonomous University of Madrid (UAM) has succeeded in bringing X-ray photoelectron spectroscopy to the femtosecond time scale. This advance, published in Nature Communications , will not only make it possible to investigate the effects on chemical bonds due to the movements of atomic nuclei, but also those caused by electronic dynamics.

Researchers at the Center for Theoretical Physics lead work on testing quantum gravity on a quantum processor. For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this experiment didn't create a disruption of physical space and time in the way we might understand the term "wormhole" from science fiction, calculations from the experiment showed that qubits traveled from one system of entangled particles to another in a model of gravity.

Experimental physicists at the University of Toronto are closer to understanding why some icicles form with ripples up and down their outsides, while others form with smooth, slick, even surfaces. By growing icicles from water samples with different contaminants like sodium chloride (salt), dextrose (sugar) and fluorescent dye, the researchers discovered that water impurities become entrapped within icicles as they form and subsequently create chevron patterns that contribute to a ripple effect around their circumferences.

Scientists at EPFL have developed photonic integrated circuits that demonstrated a new principle of light amplification on a silicon chip. It can be employed for optical signals like those used in Lidar, trans-oceanic fiber amplifiers or in data center telecommunications. The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society.

Researchers decrypt transport dynamics of porous media What laws govern how chemicals pass through filters? How do droplets of oil move through layers of stone?
