Witryna24 gru 1999 · Abstract. The spin dynamics of an arbitrary localized impurity in an insulating two-dimensional antiferromagnet, across the host transition from a paramagnet with a spin gap to a Néel state, is described. The impurity spin susceptibility has a Curie-like divergence at the quantum-critical coupling, but with a universal … Witryna10 cze 2016 · Ca-doped Na+- β/β′′-alumina was synthesized using a solid-state reaction. The changes in the properties of Na+- β/β′′-alumina resulting from the presence of Ca impurity were studied. Ca (0–5 wt%) was added to the respective samples, which were then sintered. The specimens were characterized using X-ray diffraction, scanning …

Witryna8 lis 2024 · Electrospray Ionization Mass Spectrometry is a technique used to determine molecular weights for proteins, peptides, and other biological macromolecules such as oligosaccharides 1. Originally described by Canadian-American Physicist Sir Arthur J. Dempster in an article titled "A new method of positive ray analysis." WitrynaThe reliable and accurate analysis of impurity peaks can also be achieved via mass spectrometry. During the above separations, the impurity peak (m/z) 278.4 amu, was examined. Figure 3 shows the SIR of the amitriptyline impurity on both the CORTECS C 18 +, 2.7 μm Column and the competitor solid-core C 18 column.
