Repeating this procedure for all signals in the NMR spectra gives information about the chemical composition of the sample and also dynamics such as motion and interaction between different chemicals ...

REFV AFMIR enhances nanoscale characterization, offering simultaneous chemical and mechanical insights with high spatial resolution and reduced lateral forces.

Researchers can switch between spectral maps, kinetic decays ... characterized reference material to become familiar with signal behavior and instrument operation. Pay attention to pump energy, sample ...

Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, ...

Under the high-dimensional setting that the data dimension and sample size tend to infinity proportionally, we derive the limiting spectral distribution and establish the central limit theorem of the ...

Delivering an asteroid sample OSIRIS-REx, which stands for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer, is NASA’s first asteroid sample return mission.
