Atom Probe Tomography News Today

By analyzing tiny lunar crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth’s Moon. Although previous assessments estimated the Moon as 4.425 billion years old, the new study discovered it is actually 4.46 billion years old — 40 million years older than previously thought.

Zircon crystals hidden within lunar dust samples collected during the Apollo 17 mission in 1972 have revealed that the moon is 40 million years older than previously believed.

The discovery was made possible by a new approach known as atom probe tomography, which involves using a laser to evaporate atoms from crystals.

This study discusses atom probe tomography (APT) and the feasibility of using a novel script-controlled focused ion beam-scanning electron microscopy (FIB-SEM) system for tip fabrication to improve the reliability and reproducibility of the APT technique.

This article outlines how to enable Li-ion batteries with cryo-FIB and Atom probe tomography.

Catalyst surfaces have rarely been imaged in such detail before. And yet, every single atom can play a decisive role in catalytic activity. A German-Chinese research team has visualised the three ...

Abstract Continuous innovations in design of advanced structural steels are essential for future progress in manufacturing, automotive and construction industries. Events taking place at nano and atomic scales play crucial role in controlling the strength of steels. Recently, strengths of 1–1.5 GPa were realised in nano-scale precipitation strengthened steels. With availability of modern characterisation techniques, such as high-resolution scanning transmission electron microscopy and atom pr...

Non-Members can purchase the recording for $50 This three-part webinar series delves deeper into alloy design, a topic explored in an earlier roundtable discussion. TMS is reconvening experts to discuss the design of new alloys suited for metal additive manufacturing (AM), with a focus on computational approaches and experimental approaches. The topics will cover important aspects of processing and postprocessing in alloy design. In particular, the presenters will discuss ICME-based alloy desig...
