What is Atom Probe Tomography? Atom Probe Tomography (APT) is a powerful analytical technique that provides three-dimensional (3D) imaging and chemical composition analysis of materials at the atomic ...

Researchers with the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have created an innovative method to visualize and analyze atomic structures ...

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 ...

Control over a material's final atomic structure is essential to changing that material's properties. This is especially true for materials with quantum properties that respond rapidly to slight ...

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, ...

(Nanowerk Spotlight) At the scale of individual atoms, materials behave in ways that defy everyday intuition. Stretch a metal wire by a few micrometers and its resistance changes only slightly.

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

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 ...

Antiferromagnetic materials, with antiparallel atomic spins and zero net magnetization, are fast and resistant to external magnetic interference, making them ideal for high-speed, high-density ...

Chemists have developed an efficient skeletal editing method for frequently used heteroaromatic structures. The technique could serve as a means to chemically modify biologically active compounds.
