The Nature Index 2024 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 ...

When looking at calcite under a microscope, a scientist would immediately recognize the crystalline form of calcium carbonate by its rhombohedral appearance. That is, calcite is shaped like a ...

X-ray diffraction studies confirm that, with few exceptions, each skeletal element of echinoderms is a single crystal of magnesium-rich calcite and that a relation exists between the shape of the ...

X-ray crystallography is a powerful non-destructive technique for determining the molecular structure of a crystal. X-ray crystallography uses the principles of X-ray diffraction to analyze the sample ...
