Why is ruby red and emerald green? These colors come from the same metal with the atomic structure
Credit: Pixabay/CC0 Public domain Ruby and emerald colors are very impressive, so they define red and green colors, red and emerald green. But have you ever wondered how they would do those colors? I am an inorganic chemist. Researchers in my field work to understand the chemistry of all elements that make up the periodic table. Many inorganic chemists are…

Redefining the second: Optical atomic clock achieves record precision in comparative measurements
A new In+/Yb+ crystal clock ion trap in a vacuum chamber. Credit: PTB The next generation of atomic clocks “keep time” at laser frequencies. This is about 100,000 times faster than the microwave frequency of cesium clocks, which currently generate seconds. These optical clocks are still being evaluated, but some are already 100 times more accurate than cesium clocks. They…

Atomic force microscopy reveals microtubule defects with submolecular resolution
Figure 1. High-resolution AFM images of the inner and outer surfaces of microtubules. Credit: Nano Letters (2024). DOI: 10.1021/acs.nanolett.4c04294 In a study recently published in the journal Nano Letters, researchers at Kanazawa University Nano Life Science Institute (WPI-NanoLSI) used frequency-modulated atomic force microscopy to examine the inner surfaces of microtubules (MTs) and microtubules. We revealed the submolecular structure of the…

Distorting the atomic arrangement of materials could lead to cleaner, smarter devices
Credit: Advanced Materials (2024). DOI: 10.1002/adma.202408664 What’s the best way to precisely manipulate a material’s properties to the desired state? According to a team led by researchers at Penn State University, it may be putting stress on the material’s very atoms. Researchers have discovered that by “spray painting” atoms of potassium niobate, a material used in advanced electronics, they can…

Atomic sensors reveal hidden dynamics of molecular polarization
A small cell containing rubidium metal. The central magnetic field sensing component within an atomic magnetometer. Credit: ICFO Magnetic resonance imaging (MRI) has long been a cornerstone of modern medicine and provides highly detailed images of internal organs and tissues. MRI machines are large tube-shaped magnets commonly found in hospitals that use powerful magnets to map the density of water…
