Physicists have finally done what once sounded like science fiction: they have read the X-ray “fingerprint” of a single atom, isolating the signal of one of nature’s smallest building blocks from the ...

Atomic Absorption Spectroscopy (AAS) is a technique that deals with the absorption of electromagnetic radiation of free gaseous atoms at a specific wavelength. AAS allows the measurement of extremely ...

Researchers led by Prof. ZHOU Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom ...

Ocean Optics reports on how spectroscopy revolutionizes research by utilizing light to analyze materials, improving accuracy ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Researchers discover that embedding iridium atoms inside catalyst crystals instead of on the surface dramatically improves ...

This image shows (a) the Nature magazine cover; (b) the single atom X-ray mechanism; (c) a supramolecular ring with one iron atom; (d) X-ray spectra of one iron atom; (e) a terbium dimer complex; (f) ...

Scanning Tunneling Microscopes (STMs) are amazing tools which can manipulate singular atoms, but they cannot characterize these atoms as they act only on the outer electron shell. Meanwhile X-ray ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...
