NMAH copy purchased with funds from the S. Dillon Ripley Endowment. This comprehensive scientific history presents for the first time a detailed and comprehensive study of the Bohr atom in all its ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the universe. Understanding the structure of the atomic nucleus is crucial for ...

A firefly-inspired AI framework makes atomic structure prediction more robust by combining multimodal search with an uncertainty-aware machine learning technique. The method improves efficiency for ...

Cryo-electron microscopy has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high-resolution ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

A team of researchers has identified atomic distortions that may be linked with high-temperature superconductivity in a promising class of nickel-based materials, offering new insight into how ...
