DELTA is a 1.5-GeV synchrotron radiation source operated by the TU Dortmund University. This singular university-based facility with emphasis on research and education, offers high degree of flexibility both for user experiments and accelerator physics and technology. Most of the world’s synchrotrons are designed to provide a continuous supply of radiation to users in a […]

Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a sheet of paper. But quantum physics tells a different story. In reality, nature resists rigidity and forces even the simplest structures into the […]

When we think of atoms sitting on a surface, we tend to imagine them as fairly still, especially at very low temperatures (colder than liquid nitrogen, in fact). Yet in modern surface science we often discover the opposite: atoms can be surprisingly restless, gliding from place to place in ways that shape how materials grow […]

Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]

When you hear the word nanoparticle, it might sound like something futuristic or abstract. In reality, nanoparticles—tiny structures tens of thousands of times smaller than the width of a human hair—are already part of modern medicine. Some are used to deliver drugs more effectively, while others help doctors see inside the body by acting as […]

By Mapping Ignorance

A team of researchers has experimentally demonstrated a quantum tornado for the first time by refining an established method. In the quantum semimetal tantalum arsenide (TaAs), electrons in momentum space behave like a swirling vortex. This quantum phenomenon was first predicted eight years ago. Scientists have long known that electrons can form vortices in quantum […]

Catalysis in industry is often driven by empirical investigations and, eventually, by unexpected discoveries. Frequently, the scientific understanding of the process takes much longer to develop. Ideally, it would be preferable to reverse this timeline, where scientific insights precede application. Nonetheless, even when the scientific explanation takes more time, a deep understanding of the underlying […]

C-H bond The emission of methane, a highly potent greenhouse gas, is escalating due to livestock farming and the ongoing thawing of permafrost. Converting methane and longer alkanes into more benign and valuable chemicals presents an opportunity to mitigate these hazards while providing a vast resource for the chemical industry. Nevertheless, the conversion of methane […]

Scientists have successfully demonstrated that autonomous methods can discover new materials. The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The newly discovered structures were formed by a process called self-assembly, in which a material’s molecules organize themselves into unique patterns. Scientists at Brookhaven’s Center for […]

There are instances in which you would intentionally deliver nanoparticles to animals (humans included). Contrast agents for medical diagnosis or therapeutic ones for medical treatments are two examples. It is also the case with plants, as some fertilizers take the form of nanoparticles. Unintentional exposure of animals or plants to nanoparticles is also possible: environmental […]
