Imaging Nuclear Shapes by Smashing them to Smithereens

Researchers demonstrated a new way to reveal the shapes of atomic nuclei. The method analyzes the flow and momentum of particles from high-energy collisions of nuclei. Those flow patterns are linked to the shape of nuclear matter created in these...

New Progress Toward the Discovery of New Elements

Researchers recently created two atoms of livermorium (element 116) using a new approach that offers a path to discovering even heavier elements. This brings scientists closer to creating a new element with 120 protons, which would push the...

Understanding the Adsorption Properties of Terbium for Future Medical Use

Terbium-161 (Tb-161) is a radiolanthanide that shows promise for use in theranostic nuclear medicine. To obtain Tb-161 in a form amenable for medical use, the isotope must be separated from gadolinium, generally using DGA...

Oxygen Tweaking May Be the Key to Optimizing Particle Accelerators

Many particle accelerators rely on superconducting radiofrequency components made of niobium. Nuclear physicists found that dissolving oxygen atoms a few micrometers into niobium greatly improves the performance of components made of the metal. Now,...

Molecular Modeling Reveals How Nanocrystals Take Shape

The shape of nanoparticles depends on the choice of solvent and temperature during their growth, but the seed particles that form first are too small to measure accurately. Researchers have developed a new approach to successfully model seed...

In an Advance for Promethium Production, Researchers Get a New View of the Element’s Properties

Promethium’s short half-life and lack of stable isotopes makes it difficult to study. In addition, promethium is difficult to separate from other lanthanide elements because of these elements’ similarity. In this study, scientists created a pure...

New Approach to Materials Synthesis—with Quick Validation by a Robotic Lab

To make inorganic materials such as catalysts, industry mixes precursor powders and fires them in an oven. This often produces a mix of compositions and structures. In this study, researchers developed a new way to select precursors to increase...
