or a Bruker AVANCE III 400 solid-state NMR spectrometer using TopSpin (version 3.7.0). Chemical shifts were referenced to the signal of the residual solvent protons. Mestrenova software by Mestrelab ...

Einsteinium-255, produced through irradiation in ILL’s high-flux reactor, provided a continuous supply of fermium-255, ...

Several metrics can be used to evaluate chemical shifts, peak patterns, intensities, and line shapes to determine how closely they match. All NMR parameters from the molecular structure available in ...

The roots of A. continentalis were purchased in a local market in Seoul, Korea, in May 2020. All solvents for extraction were of low particulate grade and purchased from SK chemicals (Ulsan, Korea).

The experimental results are shown in Table 1. TABLE 1. The effect of heating method and solvent on reaction. FIGURE 4. The effect of catalyst type on reaction. Reaction conditions: xylose (60 g/L), 0 ...

Even though several plants of this genus had already been investigated, the use of a simple bioassay was able to guide the chemical fractionation to a new bioactive naphthoquinone. Thus, besides ...

We are members of the QSNET consortium whose aim is to build a network of quantum sensors for testing variations of the fine structure constant, α, and the proton-to-electron mass ... to DC Stark or ...
