The atomic weight of an element having more than one principal isotope is calculated both from the atomic masses of the isotopes and from the relative abundance of each isotope in nature. For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses...
Low-energy electron-collision processes in molecular chlorine The results of close-coupling calculations using the complex Kohn variational method are reported for a variety of low-energy electron-collision processes ... Rescigno,N T. - 《Physical Review A Atomic Molecular & Optical Physics》 被引量...
for the preparation and oxidation of pure bismuth, we have developed techniques for chlorine determination in bismuth and bismuth oxide: indirect, using atomic absorption spectrometry, and direct, using laser mass spectrometry, with detection limits of 1 × 10 3 and 1 × 10 5 wt %, respectively...

Perhaps the classic example concerns the dissociation energy of the fluorine molecule which is difficult to measure experimentally: for many years this was taken to be ˜265 kJ mol−1 by extrapolation of the values for iodine, bromine, and chlorine (151, 193, and 243 kJ mol−1), ...
This was distinct from the case for Ru foil, the first shell scattering of which is located at 2.30 Å. From these observations, we assigned the primary feature at 1.48 Å to be Ru–N bonding42. The atomic dispersion of Ru was also evidenced by the wavelet transform (WT) ...
2j, k). The thickness of the grown Pt0Mn0 is ~ 0.42 nm (Fig. 2l and Supplementary Fig. 4), consistent with the thickness of a Pt0Mn0 single-atom layer. The mass loading of Pt and Mn in Pt0Mn0/GDY was 13.14 wt% and 2.36 wt%, respectively, determined by inductively...

Ru1/D-NiFe LDH with only 1.2 wt% of Ru single atoms has the catalytically most active polarization curve with a near zero onset potential. Ru1/D-NiFe LDH delivers the overpotentials of 18 and 61 mV to reach the current densities of 10 and 100 mA cm−2, which are lower ...
However, the ratio of Cl to Zr is reduced from 3.2 to 0.1 wt% compared with an as-deposited film with a pulse sequence of 4 s ZrCl4 pulse, 2 s purge, 3 s 1,4-BDC pulse and 1 s purge. This loss in chlorine may also contribute to a mass loss during the water ...
