Pyroxenes are a major group of rock-forming minerals. Scientists investigated the iron ion status of a calcium-rich pyroxene, using Mössbauer spectroscopy on thin sections of single crystals. The ...
Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...
Spectral phase-contrast tomography Three-dimensional rendering of a contrast-perfused mouse sample using three decomposition channels: water (soft tissues, blue), iodine (vasculature, red) and calcium ...
