PiFM combines atomic force microscopy with chemical imaging, offering insights into molecular orientation and surface ...

Researchers have enhanced hydrogen evolution efficiency by converting imine to amide linkages in COFs, revealing how surface charge modulates Pt photodeposition and photocatalytic performance.

Applications testing at 1.3 GHz proton frequency was conducted using five different ... chemical elements with quadrupolar and low-gamma nuclei." "We are thrilled to be among the first scientists to ...

Abstract: One challenge of chemical exchange saturation transfer ... quantitative improvements in images from three different orientations. We also extracted molecular contrast maps, including the ...

Experimental demonstration of MODIST, including at different rf ... with small isotropic chemical shift differences, a 22.5° flip angle will yield higher transfer efficiency than a 45° flip angle.

Taken together our results indicate that, although all the metal ions here studied accelerate αS aggregation, they attain different binding modes with ... MG-G performed the NMR measurements and data ...

This system is also responsible for data acquisition and subsequent mathematical transformation into an NMR spectrum. The spectrum contains a series of peaks of different intensities as a function of ...

In traditional proton—or 1 H—NMR, chemists use the chemical shifts of hydrogen atoms ... NMR frequencies are “just like different tunes, different scales, which are easy to communicate.” ...

the structure and properties of chemicals containing many different nuclei could now be comprehensively characterised. Many elements are observable by NMR, but not every atom of each element is.
